These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws;

-2-

maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain

-3-

Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

SUPPLEMENT TO THE PROSPECTUSES DATED JANUARY 1, 2006 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares and Class G shares convert to Class A shares and Class T shares after eight years, respectively. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the ""Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the ""Annual Fees and Expenses" amounts shown would be higher.

THE FUND

INVESTMENT GOAL

The Fund seeks high total return by investing in common stocks and debt securities.

PRINCIPAL INVESTMENT STRATEGIES

Normally, 35% to 65% of total net assets will be allocated to stocks and 35% to 65% will be allocated to debt securities. The Fund's stocks will primarily be those of large-cap, well-established companies. Many of the Fund's stocks have a history of paying level or rising dividends and are expected to continue paying dividends.

The Fund's debt securities generally will have intermediate- to long-term maturities. They will be primarily investment-grade, or unrated securities determined by the Fund's investment advisor to be of comparable quality, including obligations of the U.S. Government, its agencies and instrumentalities, corporate debt securities, asset-backed securities, collateralized bonds, and loan and mortgage obligations. Investment grade securities are those rated at least BBB by Standard & Poor's (S&P) or at least Baa by Moody's Investors Services, Inc. (Moody's). The Fund may also invest up to 10% of its total assets in non-investment grade securities.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

THE FUND

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative

THE FUND

positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Certain of the U.S. Government securities in which the Fund invests, such as mortgage-backed securities that are issued by government sponsored enterprises and securities issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Bank, are neither insured nor guaranteed by the United States Government. Such securities may be supported by the ability to borrow from the U.S. Treasury or only by the credit of the issuing agency or instrumentality, and, as a result, may be subject to greater issuer risk than securities issued or guaranteed by the U.S. Treasury.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense

reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were reflected, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Standard & Poor's 500 Index ("S&P Index"), an unmanaged index that tracks the performance of 500 widely held, large capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index ("Lehman Index"), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on October 1, 1991.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "Your Expenses" and "Sales Charges."

YOUR ACCOUNT

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the shares were purchased. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e., dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father-in-law and mother-in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for


12

YOUR ACCOUNT

which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS D SHARES Class D shares are closed to new investors. Your purchases of Class D shares are made at the public offering price for these shares.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.


14

YOUR ACCOUNT

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


16

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.)("CMD")(collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated undo the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In Re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

BOND SELECTION

The Fund may invest in a variety of debt securities, including bonds, debentures, notes, equipment trust certificates and short-term obligations (those having maturities of 12 months or less), such as prime commercial paper and bankers' acceptances, domestic certificates of deposit, obligations of, or guaranteed by, the U.S. Government and its agencies and instrumentalities, mortgage-backed certificates, mortgage-backed securities and other similar securities representing ownership in a pool of loans. The Fund may also invest in repurchase agreements with banks or securities dealers relating to these securities.

Mortgage-backed securities are securities representing interests in "pools" of mortgages in which payments of both interest and principal on the securities are made monthly, in effect, "passing through" monthly payments made by the individual borrowers on the mortgage loans that underlie the securities (net of fees paid to the issuer or guarantor of the securities).

Payment of principal and interest on some mortgage pass-through securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of the U.S. Government (in the case of securities guaranteed by the Government National Mortgage Association (GNMA)) or guaranteed by agencies or instrumentalities of the U.S. Government (in the case of securities guaranteed by the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC), which are supported only by the discretionary authority of the U.S. Government to purchase the agency's obligations). Mortgage pass-through securities created by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may be supported with various credit enhancements such as pool insurance, guarantees issued by governmental entities, a letter of credit from a bank or senior/subordinated structures.

The Fund will usually invest some portion of its assets in collateralized mortgage obligations (CMOs) issued by U.S. agencies or instrumentalities or in privately issued CMOs that carry an investment-grade rating. CMOs are hybrid instruments with characteristics of both mortgage-backed bonds and mortgage pass-through securities. Similar to a mortgage pass-through, interest and prepaid principal on a CMO are paid, in most cases, monthly. CMOs may be collateralized by whole mortgage loans but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by GNMA, FHLMC, or FNMA. CMOs are structured in multiple classes, with each class bearing a different stated maturity or interest rate. The Fund will only invest in those CMOs whose characteristics and terms are consistent with the average maturity and market risk profile of the other fixed income securities held by the Fund.


23

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund is permitted to invest in asset-backed securities, subject to the Fund's rating and quality requirements. Through the use of trusts and special purpose subsidiaries, various types of assets, including home equity and automobile loans and credit card and other types of receivables, as well as purchase contracts, financing leases and sales agreements entered into by municipalities, are being securitized in pass-through structures similar to the mortgage pass-through structures described above.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the

-2-

amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks high total return by investing in common stocks and debt securities.

PRINCIPAL INVESTMENT STRATEGIES

Normally, 35% to 65% of total net assets will be allocated to stocks and 35% to 65% will be allocated to debt securities. The Fund's stocks will primarily be those of large-cap, well-established companies. Many of the Fund's stocks have a history of paying level or rising dividends and are expected to continue paying dividends.

The Fund's debt securities will generally have intermediate- to long-term maturities. They will be primarily investment-grade, or unrated securities determined by the Fund's investment advisor to be of comparable quality, including obligations of the U.S. Government, its agencies and instrumentalities, corporate debt securities, asset-backed securities, collateralized bonds, and loan and mortgage obligations. Investment grade securities are those rated at least BBB by Standard & Poor's (S&P) or at least Baa by Moody's Investors Services, Inc. (Moody's). The Fund may also invest up to 10% of its total assets, in non-investment grade securities.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the


2

THE FUND

values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the


3

THE FUND

Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Certain of the U.S. Government securities in which the Fund invests, such as mortgage-backed securities that are issued by government sponsored enterprises and securities issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Bank, are neither insured nor guaranteed by the United States Government. Such securities may be supported by the ability to borrow from the U.S. Treasury or only by the credit of the issuing agency or instrumentality, and, as a result, may be subject to greater issuer risk than securities issued or guaranteed by the U.S. Treasury.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year.

results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Standard & Poor's 500 Index ("S&P Index"), an unmanaged index that tracks the performance of 500 widely held, large capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index ("Lehman Index"), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly-placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with Columbia Management Services, Inc. or your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity.

If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

YOUR ACCOUNT

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers four additional classes of shares -- Class A, B, C and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

YOUR ACCOUNT

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


12

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must


13

YOUR ACCOUNT

determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late


17

MANAGING THE FUND

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In Re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

BOND SELECTION

The Fund may invest in a variety of debt securities, including bonds, debentures, notes, equipment trust certificates and short-term obligations (those having maturities of 12 months or less), such as prime commercial paper and bankers' acceptances, domestic certificates of deposit, obligations of, or guaranteed by, the U.S. Government and its agencies and instrumentalities, mortgage-backed certificates, mortgage-backed securities and other similar securities representing ownership in a pool of loans. The Fund may also invest in repurchase agreements with banks or securities dealers relating to these securities.

Mortgage-backed securities are securities representing interests in "pools" of mortgages in which payments of both interest and principal on the securities are made monthly, in effect, "passing through" monthly payments made by the individual borrowers on the mortgage loans that underlie the securities (net of fees paid to the issuer or guarantor of the securities).

Payment of principal and interest on some mortgage pass-through securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of the U.S. Government (in the case of securities guaranteed by the Government National Mortgage Association (GNMA)) or guaranteed by agencies or instrumentalities of the U.S. Government (in the case of securities guaranteed by the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC), which are supported only by the discretionary authority of the U.S. Government to purchase the agency's obligations). Mortgage pass-through securities created by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may be supported with various credit enhancements such as pool insurance, guarantees issued by governmental entities, a letter of credit from a bank or senior/subordinated structures.

The Fund will usually invest some portion of its assets in collateralized mortgage obligations (CMOs) issued by U.S. agencies or instrumentalities or in privately issued CMOs that carry an investment-grade rating. CMOs are hybrid instruments with characteristics of both mortgage-backed bonds and mortgage pass-through securities. Similar to a mortgage pass-through, interest and prepaid principal on a CMO are paid, in most cases, monthly. CMOs may be collateralized by whole mortgage loans but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by GNMA, FHLMC, or FNMA. CMOs are structured in multiple classes, with each class bearing a different stated maturity or interest rate. The Fund will only invest in those CMOs whose characteristics and terms are consistent with the average maturity and market risk profile of the other fixed income securities held by the Fund.


19

OTHER INVESTMENT STRATEGIES

The Fund is permitted to invest in asset-backed securities, subject to the Fund's rating and quality requirements. Through the use of trusts and special purpose subsidiaries, various types of assets, including home equity and automobile loans and credit card and other types of receivables, as well as purchase contracts, financing leases and sales agreements entered into by municipalities, are being securitized in pass-through structures similar to the mortgage pass-through structures described above.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

(a) The Fund changed its fiscal year end from December 31 to August 31.

(b) On November 1, 2002, the existing Fund shares were renamed Class Z shares.

(c) Per share data was calculated using average shares outstanding during the period.

(d) Net investment income per share reflects a special dividend. The effect of this dividend amounted to $0.06 per share.

(e) Effective January 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and accreting discount on all debt securities. The effect of this change for the year ended December 31, 2001, was to decrease net investment income per share by $0.01, decrease net realized and unrealized loss per share by $0.01 and decrease the ratio of net investment income to average net assets from 2.73% to 2.70%. Per share data and ratios for periods prior to December 31, 2001 have not been restated to reflect this change in presentation.

(f) Total return at net asset value assuming all distributions reinvested.

(g) Not annualized.

(h) The benefits derived from custody credits and directed brokerage arrangements, if applicable, had an impact of less than 0.01%.

(i) Annualized.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

(2) Performance is from 1/31/95.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

-2-

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the

-3-

judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of income, with capital appreciation as a secondary goal, by investing in non-investment-grade corporate debt securities, commonly referred to as "junk" or "high-yield" bonds.

PRINCIPAL INVESTMENT STRATEGIES

Normally, the Fund will invest at least 80% of its assets (plus any borrowings for investment purposes) in bonds rated Ba or B by Moody's Investors Service, Inc. (Moody's) or BB or B by Standard & Poor's (S&P). No more than 10% of the Fund's assets will be invested in bonds rated Caa by Moody's or CCC by S&P, and no Fund assets will be invested in bonds rated, at the time of purchase, below these grades. By focusing on higher quality junk bonds, the Fund seeks access to higher yielding bonds without assuming all the risk associated with the broader junk bond market.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns. This may result in higher transaction costs and additional tax liability.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk refers to the possibility that the issuer of a bond may fail to make timely payments of interest or principal. The lower-rated bonds held by the Fund, commonly referred to as "junk bonds," are subject to greater credit risk, and are generally less liquid, than higher-rated, lower yielding bonds. These bonds may be issued to fund corporate restructurings, such as leveraged buyouts, mergers, acquisitions, debt recapitalizations, or similar events, and they are often issued by smaller, less creditworthy companies or by companies with substantial debt. The prices of such bonds are generally more sensitive than higher-rated bonds to the financial condition of the issuer and adverse changes in the economy. Changes in economic conditions or other circumstances are more likely to weaken the ability of the issuer to make principal and interest payments on these bonds than is the case for high-rated bonds. In addition, the ratings of securities provided by Moody's and S&P are estimates by the rating agencies of the credit quality of the securities. The ratings may not take into account every risk related to whether interest or principal will be repaid on a timely basis. See the Statement of Additional Information for a complete discussion of bond ratings.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were reflected, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

Beginning in 2005, the Fund's benchmark was changed to the J.P. Morgan Chase Developed BB High Yield Index ("J.P. Morgan Index"), an unmanaged index that is designed to mirror the investable universe of the U.S. dollar developed, BB-rated, high yield corporate debt market. Previously, the Fund's returns were compared to the Merrill Lynch U.S. High Yield, Cash Pay Index ("Merrill Lynch High Yield Index"), an unmanaged index that tracks the performance of non-investment-grade corporate bonds. The advisor believes that the J.P. Morgan Index, because of its greater emphasis on the investable universe of the U.S. dollar developed, BB-rated, high yield corporate debt market, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the J.P. Morgan Index, as well as the Fund's previous benchmark, the Merrill Lynch High Yield Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and Class Z shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on October 1, 1993.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. High transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.

(2) The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D shareholders.

(1) Management fee has been restated to reflect contractual changes to the management fee for the Fund effective November 1, 2004.

(2) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

(3) The Fund may pay distribution and service (12b-1) fees up to a maximum of 0.35% of the Fund's average daily net assets attributable to Class A shares (comprised of up to 0.25% for shareholder liaison services and up to 0.10% for distribution services), but will limit such fees to an aggregate fee of not more than 0.25%.

(4) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C and Class D shares. As a result, the 12b-1 fee for Class C and Class D shares would be 0.85% and 0.85%, respectively, and the total annual fund operating expenses for Class C and Class D shares would be 1.53% and 1.53%, respectively. This arrangement may be modified or terminated at any time.

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "Your Expenses" and "Sales Charges".

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

YOUR ACCOUNT

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.
A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible


12

YOUR ACCOUNT

discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. The Fund's distributor has voluntarily agreed to waive a portion of the Class C and Class D 12b-1 fee so that it does not exceed 0.85% annually. This arrangement may be modified or terminated by the Fund's distributor at any time. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
  transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. It is expected that any of the Fund's distributions will constitute qualified dividend income. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC. (Columbia Advisors), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.56% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

STEPHEN PEACHER, a managing director of Columbia Advisors, is the lead manager for the Fund and has co-managed the Fund since September, 2005. Mr. Peacher has been associated with Columbia Advisors since April, 2005.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively


20

MANAGING THE FUND

as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.


21

MANAGING THE FUND

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D Shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC))

-1-

("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

-2-

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of income, with capital appreciation as a secondary goal, by investing in non-investment-grade corporate debt securities, commonly referred to as "junk" or "high-yield" bonds.

PRINCIPAL INVESTMENT STRATEGIES

Normally, the Fund will invest at least 80% of its assets (plus any borrowings for investment purposes) in bonds rated Ba or B by Moody's Investors Service, Inc. (Moody's) or BB or B by Standard & Poor's (S&P). No more than 10% of the Fund's assets will be invested in bonds rated Caa by Moody's or CCC by S&P, and no Fund assets will be invested in bonds rated, at the time of purchase, below these grades. By focusing on higher quality junk bonds, the Fund seeks access to higher yielding bonds without assuming all the risk associated with the broader junk bond market.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.


2

THE FUND

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk refers to the possibility that the issuer of a bond may fail to make timely payments of interest or principal. The lower-rated bonds held by the Fund, commonly referred to as "junk bonds," are subject to greater credit risk, and are generally less liquid, than higher-rated, lower yielding bonds. These bonds may be issued to fund corporate restructurings, such as leveraged buyouts, mergers, acquisitions, debt recapitalizations, or similar events, and they are often issued by smaller, less creditworthy companies or by companies with substantial debt. The prices of such bonds are generally more sensitive than higher-rated bonds to the financial condition of the issuer and adverse changes in the economy. Changes in economic conditions or other circumstances are more likely to weaken the ability of the issuer to make principal and interest payments on these bonds than is the case for high-rated bonds. In addition, the ratings of securities provided by Moody's and S&P are estimates by the rating agencies of the credit quality of the securities. The ratings may not take into account every risk related to whether interest or principal will be repaid on a timely basis. See the Statement of Additional Information for a complete discussion of bond ratings.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average total annual returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

Beginning in 2005, the Fund's benchmark was changed to the J.P.Morgan Chase Developed BB High Yield Index ("J.P.Morgan Index"), an unmanaged index that is designed to mirror the investable universe of the U.S. dollar developed, BB-rated, high yield corporate debt market. Previously, the Fund's returns were compared to the Merrill Lynch U.S. High Yield, Cash Pay Index ("Merrill Lynch High Yield Index"), an unmanaged index that tracks the performance of non-investment-grade corporate bonds. The advisor believes that the J.P.Morgan Index, because of its greater emphasis on the investable universe of the U.S. dollar developed, BB-rated, high yield corporate debt market, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the J.P.Morgan Index, as well as the Fund's previous benchmark, the Merrill Lynch High Yield Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
- $10,000 initial investment
- 5% total return for each year
- Fund operating expenses remain the same
- Reinvestment of all dividends and distributions

YOUR ACCOUNT

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

YOUR ACCOUNT

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meet the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers four additional classes of shares -- Class A, B, C, and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Your Account -- Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

"Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached.

Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must


12

YOUR ACCOUNT

determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, generally based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled. Shares stop earning dividends on the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. It is expected that any of the Fund's distributions will constitute qualified dividend income. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation.

Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.56% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

STEPHEN PEACHER, a managing director of Columbia Advisors, is the lead manager for the Fund and has co-managed the Fund since September, 2005. Mr. Peacher has been associated with Columbia Advisors since April, 2005.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as


15

MANAGING THE FUND

outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.


16

MANAGING THE FUND

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z Shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratios stay the same throughout the 10-year period and reinvesting all dividends and distributions. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia

-2-

Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including

-3-

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of income exempt from federal and Oregon income tax by investing at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities issued by the State of Oregon (and its political subdivisions, agencies, authorities and instrumentalities).

PRINCIPAL INVESTMENT STRATEGIES

Normally, the Fund will invest in Oregon municipal securities rated investment grade by a securities rating agency (rated BBB or higher by Standard and Poor's (S&P) or Baa or higher by Moody's Investors Services, Inc. (Moody's)), or, if unrated, determined by the Fund's investment advisor to be of equivalent quality. The Fund may also invest in the obligations of Puerto Rico, the U.S. Virgin Islands and Guam, the interest on which is generally exempt from state income taxes. The Fund intends to maintain an average portfolio maturity of approximately 3 to 10 years.

While the Fund attempts to invest 100% of its assets in municipal securities that are exempt from federal income tax, it may invest up to 20% of its assets in securities that pay taxable interest. In such circumstances, the Fund will invest in obligations of the U.S. Government or its agencies or instrumentalities; obligations of U.S. banks (including certificates of deposit, bankers' acceptances and letters of credit) that are members of the Federal Reserve System and that have capital surplus and undivided profits as of the date of their most recent published financial statements in excess of $100 million; commercial paper rated Prime 1 by Moody's, A-1 or better by S&P, or if not rated, issued by a company that, at the time of investment by the Fund, has an outstanding debt issue rated AA or better by S&P or Aa or better by Moody's; and repurchase agreements for any of these types of investments.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

THE FUND

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds. In addition, the Fund's concentration in Oregon tax-exempt bonds may cause it to be exposed to risks that do not apply to other bond funds, such as:

- Low trading volumes for Oregon municipal bonds

- Unfavorable economic conditions in Oregon

- Legal and legislative changes affecting the ability of Oregon municipalities to issue bonds

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Municipal Market Risk and Single-State Focus: A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in the state will be affected by these factors, which will, in turn, affect the value of the Fund's investments. Because the Fund invests primarily in municipal securities of a particular state, the value of the Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.


3

THE FUND

Political risk means that a significant or potential change in tax laws affecting municipal bonds or federal income tax rates could impact municipal bond demand and cause their prices to fall.

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

If you are subject to the federal alternative minimum tax, you should be aware that up to 10% of the Fund's net assets may be invested in debt securities, the interest on which is subject to the alternative minimum tax.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause the Fund to receive taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

THE FUND


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers General Obligation Bond Index. The Lehman Brothers General Obligation Bond Index is an unmanaged index that represents average market-weighted performance of general obligation securities that have been issued in the last five years with maturities greater than one year. Unlike the Fund, the Lehman Brothers General Obligation Bond Index is not an investment, does not incur fees, expenses, or taxes and is not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and Class Z shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on July 2, 1984.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after-tax return calculation.

(1) Class A, Class B, Class C and Class D are newer classes of shares. Their performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class C shares were initially offered on October 13, 2003, Class A, B and D shares were initially offered on November 1, 2002, and Class Z shares were initially offered on July 2, 1984.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

(2) The Fund may pay distribution and service (12b-1) fees up to a maximum of 0.35% of the Fund's average daily net assets attributable to Class A shares (comprised of up to 0.25% for shareholder liaison services and up to 0.10% for distribution services), but will limit such fees to an aggregate fee of not more than 0.25%.

(3) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C and Class D shares. If this waiver were reflected in the table, the 12b-1 fee for Class C and Class D shares would be 0.65% and 0.65%, respectively, and the total annual fund operating expenses for Class C and Class D shares would be 1.27% and 1.27%, respectively. This arrangement may be modified or terminated at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example,"good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "Your Expenses" and "Sales Charges."

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are now closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e., dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for


12

YOUR ACCOUNT

which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS D SHARES Class D shares are closed to new investors. Your purchases of Class D shares are made at the public offering price for these shares. This price includes a sales charge of 1.00% (currently being waived), which is paid as a commission to your financial advisor on the sale of Class D shares as shown in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


16

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. The Fund's distributor has voluntarily agreed to waive a portion of the Class C and Class D 12b-1 fee so that it does not exceed 0.65% annually. This arrangement may be modified or terminated by the Fund's distributor at any time. Over time, these fees will reduce the return on your investment and may cost


17

YOUR ACCOUNT

you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts, (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or


18

YOUR ACCOUNT

when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

TAX CONSEQUENCES For federal income tax purposes, distributions of investment income by the Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by the Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in the Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Fund intends to distribute federally tax-exempt income. The Fund may invest a portion of its assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.50% of average daily net assets of the Fund.

PORTFOLIO MANAGER

BRIAN M. MCGREEVY, a vice president of Columbia Advisors, is the portfolio manager for the Fund and is responsible for implementing and maintaining the investment themes and strategies of the Fund. Mr. McGreevy has managed the Fund since December, 2003. Mr. McGreevy has been with Columbia Management or its predecessor organizations since December, 1994.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,


21

MANAGING THE FUND

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

-2-

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of income exempt from federal and Oregon income tax by investing at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities issued by the State of Oregon (and its political subdivisions, agencies, authorities and instrumentalities).

PRINCIPAL INVESTMENT STRATEGIES

Normally, the Fund will invest in Oregon municipal securities rated investment grade by a securities rating agency (rated BBB or higher by Standard and Poor's (S&P) or Baa or higher by Moody's Investors Services, Inc. (Moody's)), or, if unrated, determined by the Fund's investment advisor to be of equivalent quality. The Fund may also invest in the obligations of Puerto Rico, the U.S. Virgin Islands and Guam, the interest on which is generally exempt from state income taxes. The Fund intends to maintain an average portfolio maturity of approximately 3 to 10 years.

While the Fund attempts to invest 100% of its assets in municipal securities that are exempt from federal income tax, it may invest up to 20% of its assets in securities that pay taxable interest. In such circumstances, the Fund will invest in obligations of the U.S. Government or its agencies or instrumentalities; obligations of U.S. banks (including certificates of deposit, bankers' acceptances and letters of credit) that are members of the Federal Reserve System and that have capital surplus and undivided profits as of the date of their most recent published financial statements in excess of $100 million; commercial paper rated Prime 1 by Moody's, A-1 or better by S&P, or if not rated, issued by a company that, at the time of investment by the Fund, has an outstanding debt issue rated AA or better by S&P or Aa or better by Moody's; and repurchase agreements for any of these types of investments.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

THE FUND

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds. In addition, the Fund's concentration in Oregon tax-exempt bonds may cause it to be exposed to risks that do not apply to other bond funds, such as:

- Low trading volumes for Oregon municipal bonds

- Unfavorable economic conditions in Oregon

- Legal and legislative changes affecting the ability of Oregon municipalities to issue bonds

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Municipal Market Risk and Single-State Focus: A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in the state will be affected by these factors, which will, in turn, affect the value of the Fund's investments. Because the Fund invests primarily in municipal securities of a particular state, the value of the Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.


3

THE FUND

Political risk means that a significant or potential change in tax laws affecting municipal bonds or federal income tax rates could impact municipal bond demand and cause their prices to fall.

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

If you are subject to the federal alternative minimum tax, you should be aware that up to 10% of the Fund's net assets may be invested in debt securities, the interest on which is subject to the alternative minimum tax.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause the Fund to receive taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers General Obligation Bond Index. The Lehman Brothers General Obligation Bond Index is an unmanaged index that represents average market-weighted performance of general obligation securities that have been issued in the last five years with maturities greater than one year. Unlike the Fund, the Lehman Brothers General Obligation Bond Index is not an investment, does not incur fees, expenses, or taxes and is not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax deferred arrangements, such as 401(k) plans or individual retirement accounts. The return

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who

YOUR ACCOUNT

holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers four additional classes of shares -- CLASS A, B, C and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

YOUR ACCOUNT

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this fee.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, generally based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES For federal income tax purposes, distributions of investment income by the Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by the Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in the Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Fund intends to distribute federally tax-exempt income. The Fund may invest a portion of its assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.


15

YOUR ACCOUNT

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.50% of average daily net assets of the Fund.

PORTFOLIO MANAGER

BRIAN M. MCGREEVY, a Vice President of Columbia Advisors, is the portfolio manager for the Fund and is responsible for implementing and maintaining the investment themes and strategies of the Fund. Mr. McGreevy has managed the Fund since December, 2003. Mr. McGreevy has been with Columbia Management or its predecessor organizations since December, 1994.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,


17

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees.

-2-

The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March

-3-

2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation and above-average income by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in the stocks of companies principally engaged in the real estate industry, including real estate investment trusts (REITs).

PRINCIPAL INVESTMENT STRATEGIES

A company is "principally engaged" in the real estate industry if at least 50% of its gross income or net profits are attributable to the ownership, construction, management or sale of residential, commercial or industrial real estate.

A REIT is an investment vehicle that pools investors' money for investment primarily in income producing real estate or related loans or interest in another REIT. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets and income, and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year.

REITs are generally classified as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, which invests the majority of its assets directly in real properties such as shopping centers, malls, multi-family housing and commercial properties derives its income primarily from rents and lease payments. An equity REIT can also realize capital gains by selling properties that have appreciated in value. A mortgage REIT, which invests the majority of its assets in real estate mortgages, derives its income primarily from interest payments. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

THE FUND

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were reflected, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the NAREIT Index (National Association of Real Estate Investment Trusts Index) which is an unmanaged index that reflects performance of all publicly-traded equity REITs. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

CALENDAR YEAR TOTAL RETURNS (CLASS A)(1)

(BAR CHART)

16.86%     38.30%     24.74%                           28.84%      5.41%      2.97%     34.93%     30.76%

The Class's year-to-date total return         For the periods shown in bar chart:
through September 30, 2005 was +4.69%.        Best quarter: 4th quarter 1996, +18.34%
                                              Worst quarter: 3rd quarter 2002, -9.86%

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as

THE FUND

Rule 12b-1 fees) between Class A shares and Class Z shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on April 1, 1994.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Their performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "Your Expenses" and "Sales Charges".

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales change. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

YOUR ACCOUNT

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible

YOUR ACCOUNT

discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS D SHARES Class D shares are closed to new investors. Your purchases of Class D shares are made at the public offering price for these shares. This price includes a sales charge of 1.00% (currently being waived) which is paid as a commission to your financial advisor on the sale of Class D shares as shown in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your


13

YOUR ACCOUNT

letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

OUTLINED BELOW ARE THE VARIOUS OPTIONS FOR SELLING SHARES:

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held


14

YOUR ACCOUNT

by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


17

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Recent tax legislation creates potential new tax return filing and tax withholding requirements for certain foreign persons who receive distributions from the Fund that are attributable to U.S. real property interests. Prospective investors who are foreign persons should refer to the Statement of Additional Information and consult their tax advisor.

Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


19

MANAGING THE FUND

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

(a) The Fund changed its fiscal year end from December 31 to August 31.

(b) Class D shares were initially offered on November 1, 2002. Per share data and total return reflect activity from that date.

(c) Per share data was calculated using average shares outstanding during the period.

(d) Net investment income per share reflects a special dividend. The effect of this dividend amounted to $0.24 per share.

(e) Effective January 1, 2003, the Fund adopted the policy to reduce cost of investments for financial statement purposes by the distributions received in excess of income from real estate investment trusts. The effect of this change for the eight months ended August 31, 2003 was to decrease the net investment income per share by $0.05, increase net realized and unrealized gain on investments per share by $0.05 and decrease the ratio of net investment income to average net assets from 2.44% to 2.02%. Per share data and ratios prior to August 31, 2003 have not been restated to reflect this change in policy.

(f) Total return at net asset value assuming all distributions reinvested and no contingent deferred sales charge.

(g) Not annualized.

(h) The benefits derived from custody credits and directed brokerage arrangements, if applicable, had an impact of less than 0.01%.

(i) Annualized.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and

-1-

Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

-2-

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation and above-average income by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in the stocks of companies principally engaged in the real estate industry, including real estate investment trusts (REITs).

PRINCIPAL INVESTMENT STRATEGIES

A company is "principally engaged" in the real estate industry if at least 50% of its gross income or net profits are attributable to the ownership, construction, management or sale of residential, commercial or industrial real estate.

A REIT is an investment vehicle that pools investors' money for investment primarily in income producing real estate or related loans or interest in another REIT. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets and income, and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year.

REITs are generally classified as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, which invests the majority of its assets directly in real properties such as shopping centers, malls, multi-family housing and commercial properties derives its income primarily from rents and lease payments. An equity REIT can also realize capital gains by selling properties that have appreciated in value. A mortgage REIT, which invests the majority of its assets in real estate mortgages, derives its income primarily from interest payments. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

THE FUND

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Inflation risk is a risk to investors who invest in fixed income instruments, such as bond or money market funds, because there is a chance that the returns on these instruments may not keep pace with inflation. Inflation represents the rising cost of goods and services over time.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the NAREIT Index (National Association of Real Estate Investment Trusts) an unmanaged index that reflects performance of all publicly-traded equity REITs. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

The Class's year-to-date total return         For the periods shown in bar chart:
through September 30, 2005 was +4.92%.        Best quarter: 4th quarter 1996, +18.34%
                                              Worst quarter: 3rd quarter 2002, -9.86%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

YOUR ACCOUNT

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- CLASS Z.

The Fund also offers four additional classes of shares -- CLASS A, B, C and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-345-6611 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


11

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for holidays.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must


12

YOUR ACCOUNT

determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Recent tax legislation creates potential new tax return filing and tax withholding requirements for certain foreign persons who receive distributions from the Fund that are attributable to U.S. real property interests. Prospective investors who are foreign persons should refer to the Statement of Additional Information and consult their tax advisor.

(which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as


15

MANAGING THE FUND

outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

MANAGING THE FUND

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last six fiscal periods, which run from September 1 to August 31, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z Shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

CLASS A, B AND C SHARES
(REPLACING SUPPLEMENTS DATED FEBRUARY 3, 2006 AND FEBRUARY 17, 2006)

The Prospectus is hereby supplemented with the following information:

1. The second paragraph under the heading "THE FUND; PRINCIPAL INVESTMENT STRATEGIES" is revised in its entirety as follows:

The Fund may invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts (derivatives). The Fund may also invest up to 20% of its total assets in foreign securities, including American Depositary Receipts.

2. The "Calendar Year Total Returns" and "Average Annual Total Returns" tables for the Fund in the section entitled "Performance History" are updated and restated in their entirety as follows:

CALENDAR YEAR TOTAL RETURNS (CLASS Z)(1)

1997    1998    1999     2000     2001      2002      2003     2004     2005

For the periods shown in bar chart:
Best quarter: 4th quarter 1999, +50.27%
Worst quarter: 3rd quarter 2001, -25.64%

(1) Because the Class A shares have not completed a full calendar year, the bar chart shown is for Class Z shares, the oldest existing fund class. Class Z shares are not offered in this prospectus. Class A shares would have substantially similar annual returns because they are invested in the same portfolio of securities and the returns would differ only to the extent that the classes do not have the same expenses.

(1) Because Class A, Class B and Class C shares have not yet completed a full calendar year of operations, the performance information shown is that of the Fund's Class Z shares (the oldest existing fund class). These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown would have been lower since Class Z shares are not subject to any Rule 12b-1 fees. Class A, Class B and Class C shares were initially offered on November 1, 2005 and Class Z shares were initially offered on October 1, 1996.

3. The section in the prospectus entitled "MANAGING THE FUND; PORTFOLIO MANAGER" is retitled "MANAGING THE FUND; PORTFOLIO MANAGERS" and is revised in its entirety and replaced with the following:

4. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

-3-

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

6. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Standard & Poor's SmallCap 600 Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment goal, the Fund will focus on growth stocks. There is no minimum aggregate market valuation for a company to be considered an appropriate investment for the Fund. The Fund may also invest up to 20% of its net assets in larger-cap stocks when the Fund's investment advisor believes they offer capital appreciation potential that is generally comparable to small-cap stocks.

The Fund may invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts (derivatives). The Fund may also invest in foreign securities, including American Depositary Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.


2

THE FUND

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.


3

THE FUND

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of the Fund's Class Z expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and for the life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies based on market capitalization. The Fund's returns are also compared to the Russell 2000 Growth Index, an unmanaged index that measures the performance of those Russell 2000 Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

The Class's year-to-date total return         For the periods shown in bar chart:
through September 30, 2005 was +9.66%.        Best quarter: 4th quarter 1999, +50.27%
                                              Worst quarter: 3rd quarter 2001, -25.64%

(1) Because the Class A shares have not completed a full calendar year, the bar chart shown is for Class Z shares, the oldest existing Fund class. Class Z shares are not offered in this prospectus. Class A shares would have substantially similar annual returns because they are invested in the same portfolio of securities and the returns would differ only to the extent that the classes do not have the same expenses.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Because Class A, Class B and Class C shares have not yet completed a full calendar year of operations, the performance information shown is that of the Fund's Class Z shares (the oldest existing fund class). These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown would have been lower since Class Z shares are not subject to any Rule 12b-1 fees. Class A, Class B and Class C shares were initially offered on November 1, 2005 and Class Z shares were initially offered on October 1, 1996.

(2) Performance information is from October 1, 1996.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.


10

YOUR ACCOUNT

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

YOUR ACCOUNT

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Fund, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Automatic conversion to Class A shares occurs eight years after purchase.

CLASS C SHARES Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares, as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

YOUR ACCOUNT

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by the financial service firm to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


16

YOUR ACCOUNT

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.91% of average daily net assets of the Fund.

PORTFOLIO MANAGER

KENNETH A. KORNGIEBEL, a senior vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since June, 2004. Mr. Korngiebel has been associated with Columbia Advisors or its predecessors since July, 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


19

MANAGING THE FUND

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including


20

MANAGING THE FUND

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Standard & Poor's SmallCap 600 Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment goal, the Fund will focus on growth stocks. There is no minimum aggregate market valuation for a company to be considered an appropriate investment for the Fund. The Fund may also invest up to 20% of its net assets in larger-cap stocks when the Fund's investment advisor believes they offer capital appreciation potential that is generally comparable to small-cap stocks.

The Fund may invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts (derivatives). The Fund may also invest in foreign securities, including American Depositary Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.


2

THE FUND

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.


3

THE FUND

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and for the life of the Fund periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies based on market capitalization. The Fund's returns are also compared to the Russell 2000 Growth Index, an unmanaged index that measures the performance of those Russell 2000 Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


11

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.


12

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution

which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.91% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

KENNETH A. KORNGIEBEL, a senior vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since June, 2004. Mr. Korngiebel has been associated with Columbia Advisors or its predecessors since July, 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


16

MANAGING THE FUND

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including


17

MANAGING THE FUND

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

WAYNE M. COLLETTE, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Collette has been associated with Columbia Advisors or its predecessors since 2001. Prior to 2001, Mr. Collette was an associate portfolio manager with Neuberger Berman from 1999 to 2001.

J. MICHAEL KOSICKI, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Kosicki has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Kosicki was with Fidelity Investments from 1993 to 2004, most recently as an equity analyst.

GEORGE J. MYERS, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Myers has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Myers was a portfolio manager with Dresdner RCM Global Investors from 1999 to 2004.

THEODORE R. WENDELL, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Wendell has been associated with Columbia Advisors or its predecessors since 2000.

6. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things,

-3-

requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

-4-

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment goal, the Fund will focus on growth stocks. The Fund may also invest up to 20% of its net assets in small-cap and large-cap companies, as compared to the Russell Midcap Index, when the advisor believes they offer comparable capital appreciation opportunities or may help stabilize the portfolio. Columbia will monitor economic conditions to determine the appropriate percentage of the Fund's assets that will be invested in mid-cap companies.

The Fund may invest in special situations such as initial public offerings (IPOs); companies that may benefit from technological or product developments or new management; and companies involved in tender offers, leveraged buy-outs or mergers.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts (derivatives). The Fund may also invest, to a limited extent, in foreign securities, including American Depository Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management

THE FUND

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

THE FUND

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special situations have risk because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were reflected, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell Midcap Index and the Russell Midcap Growth Index. The Russell Midcap Index is an unmanaged index that tracks the performance of the 800 smallest companies in the Russell 1000 Index. The Russell Midcap Growth Index is an unmanaged index that tracks the performance of those Russell Midcap companies with higher price-to-book ratios. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 20, 1985.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "Your Expenses" and "Sales Charges."

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers additional classes of shares, exclusively to certain institutional and other investors. These shares are made available through separate prospectuses provided to these investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on

the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

YOUR ACCOUNT

REDUCED SALES CHARGES FOR LARGER INVESTMENTS
A. What are the principal ways to obtain a breakpoint discount? There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e., dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts? The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father-in-law and mother-in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount? The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or


12

YOUR ACCOUNT

other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts? Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary


14

YOUR ACCOUNT

to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern


17

YOUR ACCOUNT

time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


18

YOUR ACCOUNT

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.81% of average daily net assets of the Fund.

PORTFOLIO MANAGER

KENNETH A. KORNGIEBEL, Senior Vice President of Columbia Advisors, manages the Fund and has managed the Fund since June, 2004. Mr. Korngiebel has been associated with Columbia Advisors or its predecessors since July, 1996.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

MANAGING THE FUND

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In Re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

SUPPLEMENT TO THE PROSPECTUS DATED JANUARY 1, 2006
(REPLACING THE SUPPLEMENT DATED FEBRUARY 17, 2006)

COLUMBIA MID CAP GROWTH FUND (THE "FUND")

CLASS R SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The third paragraph under the heading "THE FUND - PRINCIPAL INVESTMENT STRATEGIES" is revised in its entirety as follows:

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts (derivatives). The Fund may also invest, to a limited extent, in foreign securities, including American Depository Receipts. The Fund may invest up to 20% of its total assets in foreign securities.

4. The "Calendar Year Total Returns" and "Average Annual Total Returns" tables for the Fund in the section entitled "Performance History" are updated and restated in their entirety as follows:

CALENDAR YEAR TOTAL RETURNS (CLASS A)(1)(2)

 1996    1997    1998    1999    2000    2001     2002     2003   2004    2005

For the periods shown in bar chart:
Best quarter: 4th quarter 1999, +37.43%
Worst quarter: 1st quarter 2001, -20.28%

(1) Because the Class R shares have not completed a full calendar year, the bar chart and average annual total returns shown are for Class A shares. Class A shares are not offered in this prospectus. Class R shares would have substantially similar annual returns because they are invested in the same portfolio of securities, and the returns would differ only to the extent that the classes do not have the same expenses and Class R shares do not have a sales charge.

(2) Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A shares. If differences in expenses had been reflected, the returns shown for periods prior to the

inception of Class A shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 20, 1985.

Mr. Myers has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Myers was a portfolio manager with Dresdner RCM Global Investors from 1999 to 2004.

THEODORE R. WENDELL, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Wendell has been associated with Columbia Advisors or its predecessors since 2000.

6. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment objective, the Fund will focus on growth stocks. The Fund may also invest up to 20% of its net assets in small-cap and large-cap companies, as compared to the Russell Midcap Index, when the advisor believes they offer comparable capital appreciation opportunities or may help stabilize the portfolio. Columbia will monitor economic conditions to determine the appropriate percentage of the Fund's assets that will be invested in mid-cap companies.

The Fund may invest in special situations such as initial public offerings (IPOs); companies that may benefit from technological or product developments or new management; and companies involved in tender offers, leveraged buy-outs or mergers.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts (derivatives). The Fund may also invest, to a limited extent, in foreign securities, including American Depository Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.


2

THE FUND

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating

histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special situations have risk because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

Because Class R shares have not been offered for a full calendar year, the bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were reflected, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class A average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell Midcap Index and the Russell Midcap Growth Index. The Russell Midcap Index is an unmanaged index that tracks the performance of the 800 smallest companies in the Russell 1000 Index. The Russell Midcap Growth Index is an unmanaged index that tracks the performance of those Russell Midcap companies with higher price-to-book ratios. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Because the Class R shares have not completed a full calendar year, the bar chart and average annual total returns shown are for Class A shares. Class A shares are not offered in this prospectus. Class R shares would have substantially similar annual returns because they are invested in the same portfolio of securities, and the returns would differ only to the extent that the classes do not have the same expenses and Class R shares do not have a sales charge.

(2) Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of Class A shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 20, 1985.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

HOW TO BUY SHARES

All orders for the purchase of Class R shares must be made through your eligible retirement plan.

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class R shares of the Fund, directly or by exchange. Eligible Investors are as follows:

- 401(k) plans;

- 457 plans;

- Employer-sponsored 403(b) plans;

- Profit sharing and money purchase pension plans;

- Defined benefit plans; and

- Non-qualified deferred compensation plans ("eligible retirement plans").

Class R shares will not be available to retail nonretirement accounts, traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, Simple IRAs, individual 403(b) plans or 529 tuition programs.

The Fund reserves the right to change the criteria for Eligible Investors. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class R shares are at net asset value, which is the value of a Class R share excluding any sales charge. Class R shares are not subject to an initial sales charge when purchased or contingent deferred sales charge when sold.

Your financial advisor/plan sponsor may receive cumulative commissions from Columbia Management Distributors, Inc. for the shares purchased in accordance with the table below:

AMOUNT PURCHASED                                                     COMMISSION %
First $50 million                                                        0.50

Additionally, your financial advisor/plan sponsor may receive ongoing 12b-1 fees with respect to Class R shares.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- CLASS R.

The Fund also offers seven additional classes of shares -- Class A, B, C and D shares are available through a separate prospectus, Class T and G shares are available through a separate prospectus and Class Z shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on, among other factors, the assets of the plan and the amount invested in the Fund and other Funds distributed by Columbia Management Distributors, Inc. Plan sponsors should consider their eligibility for other classes of shares, including, for some plans, Class Z shares, which are not subject to 12b-1 or shareholder services fees.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class R shares of another fund distributed by Columbia Management Distributors, Inc. that offers Class R shares at net asset value. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Your Account -- Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

For information about how to sell Class R shares through your eligible retirement plan, please contact your plan administrator. You may sell shares of the Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere


9

YOUR ACCOUNT

with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

YOUR ACCOUNT

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class R shares and certain services provided to you by your financial advisor. The annual distribution fee may equal up to 0.50%. Distribution fees are paid out of the assets of Class R. Over time, this fee will reduce the return on your investment and may cost you more than paying other types of sales charges.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class R shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


11

YOUR ACCOUNT

The Fund determines the net asset value of its Class R shares by dividing total net assets attributable to Class R shares by the number of outstanding Class R shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class R shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and CMG. The lawsuit alleges that defendants violated common law


15

LEGAL PROCEEDINGS

duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class R shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

GEORGE J. MYERS, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Myers has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Myers was a portfolio manager with Dresdner RCM Global Investors from 1999 to 2004.

THEODORE R. WENDELL, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Wendell has been associated with Columbia Advisors or its predecessors since 2000.

6. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

-3-

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment goal, the Fund will focus on growth stocks. The Fund may also invest up to 20% of its net assets in small-cap and large-cap companies, as compared to the Russell Midcap Index, when the advisor believes they offer comparable capital appreciation opportunities or may help stabilize the portfolio. Columbia will monitor economic conditions to determine the appropriate percentage of the Fund's assets that will be invested in mid-cap companies.

The Fund may invest in special situations such as initial public offerings (IPOs); companies that may benefit from technological or product developments or new management; and companies involved in tender offers, leveraged buy-outs or mergers.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts (derivatives). The Fund may also invest, to a limited extent, in foreign securities, including American Depository Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management

THE FUND

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or


3

THE FUND

diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special situations have risk because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell Midcap Index and the Russell Midcap Growth Index. The Russell Midcap Index is an unmanaged index that tracks the performance of the 800 smallest companies in the Russell 1000 Index. The Russell Midcap Growth Index is an unmanaged index that tracks the performance of those Russell Midcap companies with higher price-to-book ratios. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class T is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class T shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 20, 1985.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class G shares convert to Class T shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CLASS T SHARES Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

YOUR ACCOUNT


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts


11

YOUR ACCOUNT

include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS G SHARES Your purchases of Class G shares are made at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B shares of the Galaxy Growth Fund II purchased prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For

additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held


14

YOUR ACCOUNT

by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% of the average daily net assets attributable to Class T shares, but will not exceed the Fund's net investment income attributable to Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after a certain number of years, eliminating a portion of these fees upon conversion. Conversion generally occurs eight years after purchase, depending on the program under which you purchased your shares. See "Your Account -- Sales Charges" or the Statement of Additional Information for the conversion schedules applicable to Class G shares.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.81% of average daily net assets of the Fund.

PORTFOLIO MANAGER

KENNETH A. KORNGIEBEL, Senior Vice President of Columbia Advisors, manages the Fund and has managed the Fund since June, 2004. Mr. Korngiebel has been associated with Columbia Advisors or its predecessors since July, 1996.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.)("CMD")(collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In Re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class T and G shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

J. MICHAEL KOSICKI, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2006. Mr. Kosicki has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Kosicki was with Fidelity Investments from 1993 to 2004, most recently as an equity analyst.

Mr. Myers has been associated with Columbia Advisors or its predecessors since 2004. Prior to 2004, Mr. Myers was a portfolio manager with Dresdner RCM Global Investors from 1999 to 2004.

6. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia

-2-

Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November

-3-

3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under
Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment goal, the Fund will focus on growth stocks. The Fund may also invest up to 20% of its net assets in small-cap and large-cap companies, as compared to the Russell Midcap Index, when the advisor believes they offer comparable capital appreciation opportunities or may help stabilize the portfolio. Columbia will monitor economic conditions to determine the appropriate percentage of the Fund's assets that will be invested in mid-cap companies.

The Fund may invest in special situations such as initial public offerings (IPOs); companies that may benefit from technological or product developments or new management; and companies involved in tender offers, leveraged buy-outs or mergers.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts (derivatives). The Fund may also invest, to a limited extent, in foreign securities, including American Depository Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

THE FUND

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or

THE FUND

diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special situations have risk because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell Midcap Index and the Russell Midcap Growth Index. The Russell Midcap Index is an unmanaged index that tracks the performance of the 800 smallest companies in the Russell 1000 Index. The Russell Midcap Growth Index is an unmanaged index that tracks the performance of those Russell Midcap companies with higher price-to-book ratios. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with Columbia Management Services, Inc. or your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section


8

YOUR ACCOUNT

for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;


9

YOUR ACCOUNT

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers six additional classes of shares -- CLASS A, B, C, D, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A shares (only if Class Z is not offered) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes.


10

YOUR ACCOUNT

The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.


13

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
  transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution

which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.81% of average daily net assets of the Fund.

PORTFOLIO MANAGER

KENNETH A. KORNGIEBEL, Senior Vice President of Columbia Advisors, manages the Fund and has managed the Fund since June, 2004. Mr. Korngiebel has been associated with Columbia Advisors or its predecessors since July, 1996.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

MANAGING THE FUND

trading activity and seek, among other things, removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In Re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION
The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

Mr. White has been associated with Columbia Advisors since January, 2006.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

5. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.


In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth of capital by using a "value" approach to invest primarily in common stocks.

PRINCIPAL INVESTMENT STRATEGIES

The value approach employed by the Fund emphasizes investments in companies the Fund's investment advisor believes are undervalued relative to their intrinsic worth or prior history. The Fund devotes more attention to the growth and earnings of companies than is normally associated with a fund using a strict value approach.

A company may be undervalued due to market or economic conditions, temporary earnings declines, unfavorable developments affecting the company or other factors. Such factors may provide buying opportunities at prices attractive when compared to historical or market price-to-earnings (P/E) ratios, price-to-cash flow ratios, book value or return on equity. These "undervalued" companies may have a history of below-average earnings growth. A company's value is measured based on its P/E ratios, price/sales ratios, asset values, and discount-to-private market value.

Typically, the Fund seeks companies that are attractively valued and that are demonstrating or show the potential to demonstrate earnings growth, improving cash flow and improving return on invested capital. These may also include special situations companies that are experiencing management changes or are temporarily out of favor.

The Fund may invest in companies of any size, and may also invest a significant percentage of its assets in small- and mid-cap sized companies. The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts (derivatives). The Fund may also invest up to 33% of its assets in foreign securities, including American Depositary Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate


2

THE FUND

drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special Situations Companies have risks because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or U.S. dollars without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

The Fund may also invest in stock futures and option contracts, which are traditional types of derivatives. A derivative is a financial contract whose value is based on (or "derived" from) a traditional security (such as a stock or bond), an asset (such as a commodity like gold), or a market index (such as the S&P 500 Index). Losses (or gains) involving derivatives can sometimes be substantial. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indexes, have been trading on regulated exchanges for more than two decades. These types of derivatives are standardized contracts that generally can easily be bought and sold, and whose market values are determined and published daily. Non-standardized derivatives, on the other hand, tend to be more specialized or complex and may be harder to value. If used for


3

THE FUND

speculation or as leveraged investments, derivatives can carry considerable risk. The Fund will not use derivatives for speculative purposes or as leveraged investment that may magnify gains or losses.

Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio or predetermined price (the conversion prices). A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security's market value tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than its conversion price. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would be paid before the company's common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer's convertible securities generally entail less risk than its common stock but more risk than its debt obligations.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of broad measures of market performance for one year and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's performance over the past one-year and life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the S&P 500 Index and the Russell 3000 Value Index. The S&P 500 Index is an unmanaged index generally considered representative of the U.S. stock market. The Russell 3000 Value Index measures the performance of those Russell 3000 Index companies with lower price-to- book ratios and lower forecasted growth values. Unlike the Fund, the indexes are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and Class Z shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 9, 2000.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, See "The Fund -- Your Expenses" and "Your Account -- Sales Charges" in this Prospectus.

YOUR ACCOUNT

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on

the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those shares you have held the longest.

YOUR ACCOUNT

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e., dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father-in-law and mother-in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for


12

YOUR ACCOUNT

which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group Plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


16

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay the Fund's distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value) your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
  transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.75% of average daily net assets of the Fund.

PORTFOLIO MANAGER

EMIL A. GJESTER, a vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2002. Mr. Gjester has been associated with Columbia Advisors or its predecessors since 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures


20

MANAGING THE FUND

designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

STOCK SELECTION

In making decisions as to the securities to hold, the Fund's investment advisor employs fundamental research and evaluates the issuer based on its financial statements and operations. The Fund's investment advisor focuses on the quality of the issuer, the price of an individual issuer's common stock, and also on economic sectors. Market timing strategies may occasionally be employed. The Fund's investment advisor measures a company's value by its P/E ratio, price to cash flow ratio, price to book ratio and price-to-private market values. A P/E ratio is the relationship between the price of a stock and earnings per share and it attempts to measure how much investors are willing to pay for future earnings. This figure is determined by dividing a stock's market price by the issuing company's earnings per share. Price to cash flow is the relationship between the price of a stock and the company's available cash from operations and helps provide an understanding about expected future cash flow.

Before selecting individual securities for the Fund, the Fund's investment advisor begins with a top-down, industry sector analysis. Then, in addition to measuring value by focusing on issuing companies' P/E ratios and price/cash flow ratios, factors the portfolio manager looks for in selecting investments include, but are not limited to:

- Estimated private market value in excess of current stock price. Private market value is the price an investor would pay to own the entire company.

- Management with demonstrated ability and commitment to the company.

- Low market valuations relative to earnings forecasts, book value, cash flow and sales.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

5. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.


Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions


making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth of capital by using a "value" approach to invest primarily in common stocks.

PRINCIPAL INVESTMENT STRATEGIES

The value approach employed by the Fund emphasizes investments in companies the Fund's investment advisor believes are undervalued relative to their intrinsic worth or prior history. The Fund devotes more attention to the growth and earnings of companies than is normally associated with a fund using a strict value approach.

A company may be undervalued due to market or economic conditions, temporary earnings declines, unfavorable developments affecting the company or other factors. Such factors may provide buying opportunities at prices attractive when compared to historical or market price-to-earnings (P/E) ratios, price-to-cash flow ratios, book value or return on equity. These "undervalued" companies may have a history of below-average earnings growth. A company's value is measured based on its P/E ratios, price/sales ratios, asset values, and discount-to-private market value.

Typically, the Fund seeks companies that are attractively valued and that are demonstrating or show the potential to demonstrate earnings growth, improving cash flow and improving return on invested capital. These may also include special situations companies that are experiencing management changes or are temporarily out of favor.

The Fund may invest in companies of any size, one may also invest a significant percentage of its assets in small- and mid-cap sized companies. The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts (derivatives). The Fund may also invest up to 33% of its assets in foreign securities, including American Depositary Receipts.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset


2

THE FUND

classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospectus is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Special situations companies have risks because they often involve major corporate changes and, thus, present a high degree of uncertainty as to the security's market price.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies or U.S. dollars without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

The Fund may also invest in stock futures and option contracts, which are traditional types of derivatives. A derivative is a financial contract whose value is based on (or "derived" from) a traditional security (such as a stock or bond), an asset (such as a commodity like gold), or a market index (such as the S&P 500 Index). Losses (or gains) involving derivatives can sometimes be substantial. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indexes, have been trading on regulated exchanges for more than two decades. These types of derivatives are standardized contracts that generally can easily be bought and sold, and whose market values are determined and published daily. Non-standardized derivatives, on the other hand, tend to be more specialized or complex and may be harder to value. If used for


3

THE FUND

speculation or as leveraged investments, derivatives can carry considerable risk. The Fund will not use derivatives for speculative purposes or as leveraged investment that may magnify gains or losses.

Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio or predetermined price (the conversion price). A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security's market value tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than its conversion price. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would be paid before the company's common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer's convertible securities generally entail less risk than its common stock but more risk than its debt obligations.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual returns for Class Z shares compare with those of broad measures of market performance for one year and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year and life of the Fund periods. They include the effects of Fund expenses.

The Fund's returns are compared to the S&P 500 Index and the Russell 3000 Value Index. The S&P 500 Index is an unmanaged index generally considered representative of the U.S. stock market. The Russell 3000 Value Index measures the performance of those Russell 3000 Index companies with lower price-to- book ratios and lower forecasted growth values. Unlike the Fund, the indexes are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers four additional classes of shares -- CLASS A, B, C and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

YOUR ACCOUNT

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


12

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must


13

YOUR ACCOUNT

determine the price of each security in its portfolio at the close of each trading day. Because the Fund may hold securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.75% of average daily net assets of the Fund.

PORTFOLIO MANAGER

EMIL A. GJESTER, a vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2002. Mr. Gjester has been associated with Columbia Advisors or its predecessors since 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,


16

MANAGING THE FUND

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including


17

MANAGING THE FUND

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

OTHER INVESTMENT STRATEGIES

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

STOCK SELECTION

In making decisions as to the securities to hold, the Fund's investment advisor employs fundamental research and evaluates the issuer based on its financial statements and operations. The Fund's investment advisor focuses on the quality of the issuer, the price of an individual issuer's common stock, and also on economic sectors. Market timing strategies may occasionally be employed. The Fund's investment advisor measures a company's value by its P/E ratio, price to cash flow ratio, price to book ratio and price-to-private market values. A P/E ratio is the relationship between the price of a stock and earnings per share and it attempts to measure how much investors are willing to pay for future earnings. This figure is determined by dividing a stock's market price by the issuing company's earnings per share. Price to cash flow is the relationship between the price of a stock and the company's available cash from operations and helps provide an understanding about expected future cash flow.

Before selecting individual securities for the Fund, the Fund's investment advisor begins with a top-down, industry sector analysis. Then, in addition to measuring value by focusing on issuing companies' P/E ratios and price/cash flow ratios, factors the portfolio manager looks for in selecting investments include, but are not limited to:

- Estimated private market value in excess of current stock price. Private market value is the price an investor would pay to own the entire company.

- Management with demonstrated ability and commitment to the company.

- Low market valuations relative to earnings forecasts, book value, cash flow and sales.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the fiscal years since the inception of Class Z shares, which run from September 1 to August 31, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information is included in the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

4. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay


$70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.


On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation by investing, under normal market conditions, at least 80% of its total net assets (plus any borrowings for investment purposes) in stocks of technology companies that may benefit from technological improvements, advancements or developments.

PRINCIPAL INVESTMENT STRATEGIES

The technology companies in which the Fund invests include those that the Fund's investment advisor believes have or will develop products, processes or services that will provide significant technological improvements, advances or developments, as well as those expected to benefit from their extensive reliance on technology in connection with their operations and services.

The Fund may invest in companies from the biotechnology, cable and network broadcasting, communications, computer hardware, computer services and software, consumer electronics, defense, medical devices, pharmaceutical and semiconductor industries, among others. The Fund may invest in companies in all stages of corporate development, ranging from new companies developing a promising technology or scientific advancement to established companies with a record of producing breakthrough products and technologies from research and development efforts.

The Fund will invest in companies of all sizes, and expects to invest a significant percentage of its assets in small- and mid-cap companies.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts ("derivatives"). The Fund may also invest in foreign securities, including American Depositary Receipts.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Because the Fund concentrates in technology stocks, it is subject to sector risk and its share price will likely be subject to more volatility than the overall stock market. The risks of investing only in technology-related stocks may be greater than investing in other market sectors or in a more diversified portfolio because of:

- Competitive pressures among technology companies that result in aggressive pricing of their products or services

- Short product cycles due to an accelerated rate of technological developments

- Varying investor enthusiasm for technology and technology-related stocks

Additionally, the prices of technology stocks will likely fluctuate more than non-technology stocks because technology companies are affected by scientific and technological developments and advancements and, for biotechnology companies in particular, may be subject to government regulation, including approval of their products. Technology companies may also be subject to greater business risks and, accordingly, may be more sensitive to changes in economic conditions. Many technology companies are currently operating at a loss and may never be profitable. In addition, the share price of technology stocks may be more sensitive to companies' disappointing quarterly or annual earnings results, such as lower sales or profits than originally projected.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Foreign equity securities, which are generally denominated in foreign currencies, involve risks not typically associated with investing in domestic securities. Foreign securities may be subject to foreign taxes that would reduce their effective yield. Certain foreign governments levy withholding taxes against dividend and interest income. Although in some countries a portion of these taxes is recoverable, the unrecovered portion of any foreign withholding taxes would reduce the income the Fund receives from its foreign investments. In addition, to the extent that the securities are denominated in a foreign currency, the value of the Fund invested in foreign securities will fluctuate as a result of changes in the exchange rates between the U.S. dollar and the currencies in which foreign securities are denominated.


3

THE FUND

Foreign investments involve other risks, including possible political or economic instability of the country of the issuer, the difficulty of predicting international trade patterns, and the possibility of currency exchange controls. Foreign securities may also be subject to greater fluctuations in price than domestic securities. There may be less publicly available information about a foreign company than about a domestic company. Foreign companies generally are not subject to uniform accounting, auditing and financial reporting standards comparable to those of domestic companies.

Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio or predetermined price (the conversion price). A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security's market value tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than its conversion price. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would be paid before the company's common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer's convertible securities generally entail less risk than its common stock but more risk than its debt obligations.

The Fund may also invest in stock futures and option contracts, which are traditional types of derivatives. A derivative is a financial contract whose value is based on (or "derived" from) a traditional security (such as a stock or bond), an asset (such as a commodity like gold), or a market index (such as the S&P 500 Index). Losses (or gains) involving derivatives can sometimes be substantial. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indexes, have been trading on regulated exchanges for more than two decades. These types of derivatives are standardized contracts that generally can easily be bought and sold, and whose market values are determined and published daily. Non-standardized derivatives, on the other hand, tend to be more specialized or complex and may be harder to value. If used for speculation or as leveraged investments, derivatives can carry considerable risk. The Fund will not use derivatives for speculative purposes or as leveraged investment that may magnify gains or losses.

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B, C and D shares, including sales charges, compare with those of a broad measure of

THE FUND

market performance for one year and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's performance over the past one-year and life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Merrill Lynch 100 Technology Index. The Merrill Lynch 100 Technology Index is an equally weighted index of 100 leading technology stocks. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

CALENDAR YEAR TOTAL RETURNS (CLASS A)(1)

(BAR CHART)

                      84.17%     21.20%
-28.97%    -38.17%
 2001       2002       2003       2004

The Class's year-to-date total return         For the periods shown in bar chart:
through September 30, 2005 was +8.51%.        Best quarter: 2nd quarter 2003, +35.60%
                                              Worst quarter: 3rd quarter 2001, -37.59%

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and Class Z shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class A shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 9, 2000.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B, Class C and Class D are newer classes of shares. Their performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class C shares were initially offered on October 13, 2003, Class A, B and D shares were initially offered on November 1, 2002, and Class Z shares were initially offered on November 9, 2000.

(2) Performance information is from November 9, 2000.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table, but does reflect the waiver of the initial sales charge for Class D shares. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for the transfer agency and pricing and bookkeeping services effective November 1, 2005.

This arrangement may be modified or terminated by the advisor at any time.

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Notice to Fund Shareholders: Class D shares are closed to new investors and new accounts. The Fund now offers Class C shares, which are subject to the same service and distribution fees and sales charges as Class D shares except Class C shares are not subject to a front-end sales charge. The Fund's advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors. For more information on expenses and sales charges for Class C shares and Class D shares, see "The Fund -- Your Expenses" and "Your Account -- Sales Charges" in this prospectus.

YOUR ACCOUNT

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers four classes of shares in this prospectus -- CLASS A, B, C and D. Class D shares are closed to new investors and new accounts. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A, Class C or Class D shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C and D shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those shares you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e., dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father-in-law and mother-in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for


12

YOUR ACCOUNT

which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group Plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS D SHARES Class D shares are closed to new investors. Your purchases of Class D shares are made at the public offering price for these shares. This price includes a sales charge of 1.00% (currently being waived), which is paid as a commission to your financial advisor on the sale of Class D shares as shown in the chart below.

In addition, the distributor pays your financial advisor an initial commission of 1.00% on sales of Class D shares. The Fund's investment advisor has agreed to waive indefinitely the front-end sales charge for purchases of Class D shares by existing Class D investors.

Class D shares also carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. In the case of Class D shares, you may exchange your Class D shares for Class D shares of another fund in which you own Class D shares. Otherwise, you may exchange your Class D shares only for Class C shares. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" in this Prospectus for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


16

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12b-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay the Fund's distributor marketing and other fees to support the sale and distribution of Class A, B, C and D shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B, Class C and Class D shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B, Class C and Class D shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Directors limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

YOUR ACCOUNT

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However,


18

YOUR ACCOUNT

where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

YOUR ACCOUNT

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund, and subsequent distributions will be reinvested.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.89% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

WAYNE M. COLLETTE, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since June, 2002. Mr. Collette has been associated with Columbia Advisors or its predecessors since 2001. Prior to joining, Mr. Collette was an associate portfolio manager with Neuberger Berman from 1999 to 2001.

THEODORE R. WENDELL, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since June, 2002. Mr. Wendell has been associated with Columbia Advisors or its predecessors since 2000.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud

MANAGING THE FUND

provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.


22

MANAGING THE FUND

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these


amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks capital appreciation by investing, under normal market conditions, at least 80% of its total net assets (plus any borrowings for investment purposes) in stocks of technology companies that may benefit from technological improvements, advancements or developments.

PRINCIPAL INVESTMENT STRATEGIES

The technology companies in which the Fund invests include those that the Fund's investment advisor believes have or will develop products, processes or services that will provide significant technological improvements, advances or developments, as well as those expected to benefit from their extensive reliance on technology in connection with their operations and services.

The Fund may invest in companies from the biotechnology, cable and network broadcasting, communications, computer hardware, computer services and software, consumer electronics, defense, medical devices, pharmaceutical and semiconductor industries, among others. The Fund may invest in companies in all stages of corporate development, ranging from new companies developing a promising technology or scientific advancement to established companies with a record of producing breakthrough products and technologies from research and development efforts.

The Fund will invest in companies of all sizes, and expects to invest a significant percentage of its assets in small- and mid-cap companies.

The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), and certain options and financial futures contracts ("derivatives"). The Fund may also invest in foreign securities, including American Depositary Receipts.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques that are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Except as noted otherwise, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Because the Fund concentrates in technology stocks, it is subject to sector risk and its share price will likely be subject to more volatility than the overall stock market. The risks of investing only in technology-related stocks may be greater than investing in other market sectors or in a more diversified portfolio because of:

- Competitive pressures among technology companies that result in aggressive pricing of their products or services

- Short product cycles due to an accelerated rate of technological developments

- Varying investor enthusiasm for technology and technology-related stocks

Additionally, the prices of technology stocks will likely fluctuate more than non-technology stocks because technology companies are affected by scientific and technological developments and advancements and, for biotechnology companies in particular, may be subject to government regulation, including approval of their products. Technology companies may also be subject to greater business risks and, accordingly, may be more sensitive to changes in economic conditions. Many technology companies are currently operating at a loss and may never be profitable. In addition, the share price of technology stocks may be more sensitive to companies' disappointing quarterly or annual earnings results, such as lower sales or profits than originally projected.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Foreign equity securities, which are generally denominated in foreign currencies, involve risks not typically associated with investing in domestic securities. Foreign securities may be subject to foreign taxes that would reduce their effective yield. Certain foreign governments levy withholding taxes against dividend and interest income. Although in some countries a portion of these taxes is recoverable, the unrecovered portion of any foreign withholding taxes would reduce the income the Fund receives from its foreign investments. In addition, to the extent that the securities are denominated in a foreign currency, the value of the Fund invested in foreign


3

THE FUND

securities will fluctuate as a result of changes in the exchange rates between the U.S. dollar and the currencies in which foreign securities are denominated.

Foreign investments involve other risks, including possible political or economic instability of the country of the issuer, the difficulty of predicting international trade patterns, and the possibility of currency exchange controls. Foreign securities may also be subject to greater fluctuations in price than domestic securities. There may be less publicly available information about a foreign company than about a domestic company. Foreign companies generally are not subject to uniform accounting, auditing and financial reporting standards comparable to those of domestic companies.

Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio or predetermined price (the conversion price). A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security's market value tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than its conversion price. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would be paid before the company's common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer's convertible securities generally entail less risk than its common stock but more risk than its debt obligations.

The Fund may also invest in stock futures and option contracts, which are traditional types of derivatives. A derivative is a financial contract whose value is based on (or "derived" from) a traditional security (such as a stock or bond), an asset (such as a commodity like gold), or a market index (such as the S&P 500 Index). Losses (or gains) involving derivatives can sometimes be substantial. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indexes, have been trading on regulated exchanges for more than two decades. These types of derivatives are standardized contracts that generally can easily be bought and sold, and whose market values are determined and published daily. Non-standardized derivatives, on the other hand, tend to be more specialized or complex and may be harder to value. If used for speculation or as leveraged investments, derivatives can carry considerable risk. The Fund will not use derivatives for speculative purposes or as leveraged investment that may magnify gains or losses.

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual returns for Class Z shares compare with those of a broad measure of market performance for one year and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year and life of the Fund periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Merrill Lynch 100 Technology Index. The Merrill Lynch 100 Technology Index is an equally weighted index of 100 leading technology stocks. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc. ;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

YOUR ACCOUNT

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers four additional classes of shares -- CLASS A, B, C, and D shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Directors of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


12

YOUR ACCOUNT

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must


13

YOUR ACCOUNT

determine the price of each security in its portfolio at the close of each trading day. Because the Fund may hold securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund, and subsequent distributions will be reinvested.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling and exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Directors. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.89% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

WAYNE M. COLLETTE, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since June, 2002. Mr. Collette has been associated with Columbia Advisors or its predecessors since 2001. Prior to joining, Mr. Collette was an associate portfolio manager with Neuberger Berman from 1999 to 2001.

THEODORE R. WENDELL, a vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since June, 2002. Mr. Wendell has been associated with Columbia Advisors or its predecessors since 2000.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC, now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


16

MANAGING THE FUND

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including


17

MANAGING THE FUND

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

-2-

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the
MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

-3-

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

(EACH A "FUND" AND COLLECTIVELY, THE "FUNDS")

SUPPLEMENT TO THE PROSPECTUSES DATED JANUARY 1, 2006 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares and Class G shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth of capital.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies whose principal activities are in the Greater China Region. This region includes Hong Kong, The People's Republic of China and Taiwan, among others. The Fund's investment advisor will determine where a company's principal activities are located by considering its country of organization, the principal trading market for its stocks, the source of its revenues and the location of its assets. The Fund may invest in stocks of any size, whose earnings, the advisor believes, are in a growth trend or are undervalued.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.


2

THE FUND

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Because the Fund invests predominantly in foreign securities, the Fund may be particularly susceptible to market timers. Market timers generally attempt to take advantage of the way the Fund prices its shares by trading based on market information they expect will lead to a change in the Fund's net asset value on the next pricing day. Market timing activity may be disruptive to Fund management and, since a market timer's profits are effectively paid directly out of the Fund's assets, may negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and discourage frequent trading based on this strategy, it cannot ensure that all such activity can be identified or terminated.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

Because the Fund's investments are concentrated in the Greater China Region, the Fund is particularly susceptible to regional risks. Events in any one country within the region may impact the other countries or the Asian region as a whole. As a result, events in the region will generally have a greater effect on the Fund than if the Fund were more geographically diversified, which may result in greater losses and volatility. Markets in the Greater China Region can experience significant volatility due to social, regulatory and political uncertainties.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.


3

THE FUND

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and for the life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Morgan Stanley Capital International China Index ("MSCI China Index"), an unmanaged index that is designed to broadly and fairly represent the full diversity of business activities in China. This index aims to capture 85% of the free float adjusted market capitalization in each industry group. The Fund's returns are also compared to the Hang Seng Stock Index ("Hang Seng Index"), an unmanaged index that tracks the performance of approximately 70% of the total market capitalization of the stock exchange of Hong Kong. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charges may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

YOUR ACCOUNT

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint


10

YOUR ACCOUNT

discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions


11

YOUR ACCOUNT

under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Automatic conversion to Class A shares occurs eight years after purchase.

CLASS C SHARES Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares, as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares


12

YOUR ACCOUNT

acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


14

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, the Fund imposes a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase, as described below.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

The Fund will assess, subject to limited exceptions, a 2.00% redemption fee on the proceeds of Fund shares that are redeemed (either by selling shares or exchanging into another Columbia Fund) within 60 days of their purchase. The redemption fee is paid to the Fund.

The redemption fee is imposed on Fund shares redeemed (including redemptions by exchange) within 60 days of purchase. In determining which shares are being redeemed, we generally apply a first-in, first-out approach. For Fund shares acquired by exchange, the holding period prior to the exchange will not be considered in determining whether to assess the redemption fee.

The redemption fee will not be imposed if you qualify for a waiver and the Fund has received proper notification, unless the waiver is automatic as noted below. We'll redeem any shares that are eligible for a waiver first.


15

YOUR ACCOUNT

A Fund shareholder won't pay an otherwise applicable redemption fee on any of the following transactions:

- shares sold following the death or disability (as defined in the Internal Revenue Code) of the shareholder, including a registered joint owner

- shares sold by or distributions from participant directed retirement plans, such as 401(k), 403(b), 457, Keogh, profit sharing, and money purchase pension accounts, where the Fund does not have access to information about the individual participant account activity, except where the Fund has received an indication that the plan administrator is able to assess the redemption fee to the appropriate accounts (automatic)

- shares sold by certain investment funds, including those that Columbia Management Advisors, LLC or its affiliates may manage (automatic)

- shares sold as part of an automatic rebalancing within an asset allocation program or by certain wrap programs where the program sponsor has provided assurances reasonably satisfactory to the Fund that the program is not designed to be a vehicle for market timing

- shares sold by accounts maintained by a financial institution or intermediary where the Fund has received information reasonably satisfactory to the Fund indicating that the financial institution or intermediary maintaining the account is unable for administrative reasons to assess the redemption fee to underlying shareholders

- shares sold by an account which has demonstrated a hardship, such as a medical emergency, as determined in the absolute discretion of the Fund

- shares that were purchased by reinvested dividends (automatic)

- shares that are redeemed or exchanged thorough Columbia Funds' Systematic Withdrawal Plan or similar affiliated or unaffiliated automated plans

- the following retirement plan distributions:

- lump-sum or other distributions from a qualified corporate or self-employed retirement plan following retirement (or following attainment of age 59 1/2 in the case of a "key employee" of a "top heavy" plan)

- distributions from an individual retirement account ("IRA") or Custodial Account under Section 403(b)(7) of the Internal Revenue Code, following attainment of age 59 1/2

The Fund also has the discretion to waive the 2.00% redemption fee if the Fund is in jeopardy of failing the 90% income test or losing its registered investment company qualification for tax purposes.

As described above, certain intermediaries do not assess redemption fees to certain categories of redemptions that do not present significant market timing concerns (such as automatic withdrawal plan redemptions). In these situations, the Fund's ability to assess redemption fees is generally limited by the intermediary's policies and, accordingly, no redemption fees will be assessed on such redemptions.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-l that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.


17

YOUR ACCOUNT

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

YOUR ACCOUNT

DISTRIBUTION OPTIONS The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. The Fund's investments in foreign securities may be subject to foreign withholding taxes. You may be entitled to claim a credit or deduction with respect to foreign taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations

-2-

to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth of capital.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies whose principal activities are in the Greater China Region. This region includes Hong Kong, The People's Republic of China and Taiwan, among others. The Fund's investment advisor will determine where a company's principal activities are located by considering its country of organization, the principal trading market for its stocks, the source of its revenues and the location of its assets. The Fund may invest in stocks of any size, whose earnings, the advisor believes, are in a growth trend or are undervalued.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.


2

THE FUND

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Because the Fund invests predominantly in foreign securities, the Fund may be particularly susceptible to market timers. Market timers generally attempt to take advantage of the way the Fund prices its shares by trading based on market information they expect will lead to a change in the Fund's net asset value on the next pricing day. Market timing activity may be disruptive to Fund management and, since a market timer's profits are effectively paid directly out of the Fund's assets, may negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and discourage frequent trading based on this strategy, it cannot ensure that all such activity can be identified or terminated.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

Because the Fund's investments are concentrated in the Greater China Region, the Fund is particularly susceptible to regional risks. Events in any one country within the region may impact the other countries or the Asian region as a whole. As a result, events in the region will generally have a greater effect on the Fund than if the Fund were more geographically diversified, which may result in greater losses and volatility. Markets in the Greater China Region can experience significant volatility due to social, regulatory and political uncertainties.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

As a non-diversified mutual fund, the Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

THE FUND

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and for the life of the Fund periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Morgan Stanley Capital International China Index ("MSCI China Index"), an unmanaged index that is designed to broadly and fairly represent the full diversity of business activities in China. This index aims to capture 85% of the free float adjusted market capitalization in each industry group. The Fund's returns are also compared to the Hang Seng Stock Index ("Hang Seng Index"), an unmanaged index that tracks the performance of approximately 70% of the total market capitalization of the stock exchange of Hong Kong. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who

YOUR ACCOUNT

holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, the Fund imposes a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase, as described below.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

The Fund will assess, subject to limited exceptions, a 2.00% redemption fee on the proceeds of Fund shares that are redeemed (either by selling shares or exchanging into another Columbia Fund) within 60 days of their purchase. The redemption fee is paid to the Fund.

The redemption fee is imposed on Fund shares redeemed (including redemptions by exchange) within 60 days of purchase. In determining which shares are being redeemed, we generally apply a first-in, first-out approach. For Fund shares acquired by exchange, the holding period prior to the exchange will not be considered in determining whether to assess the redemption fee.

The redemption fee will not be imposed if you qualify for a waiver and the Fund has received proper notification, unless the waiver is automatic as noted below. We'll redeem any shares that are eligible for a waiver first.


13

YOUR ACCOUNT

A Fund shareholder won't pay an otherwise applicable redemption fee on any of the following transactions:

- shares sold following the death or disability (as defined in the tax code) of the shareholder, including a registered joint owner

- shares sold by or distributions from participant directed retirement plans, such as 401(k), 403(b), 457, Keogh, profit sharing, and money purchase pension accounts, where the Fund does not have access to information about the individual participant account activity, except where the Fund has received an indication that the plan administrator is able to assess the redemption fee to the appropriate accounts (automatic)

- shares sold by certain investment funds, including those that Columbia Management Advisors, LLC or its affiliates may manage (automatic)

- shares sold as part of an automatic rebalancing within an asset allocation program or by certain wrap programs where the program sponsor has provided assurances reasonably satisfactory to the Fund that the program is not designed to be a vehicle for market timing

- shares sold by accounts maintained by a financial institution or intermediary where the Fund has received information reasonably satisfactory to the Fund indicating that the financial institution or intermediary maintaining the account is unable for administrative reasons to assess the redemption fee to underlying shareholders

- shares sold by an account which has demonstrated a hardship, such as a medical emergency, as determined in the absolute discretion of the Fund

- shares that were purchased by reinvested dividends (automatic)

- shares that are redeemed or exchanged thorough Columbia Funds' Systematic Withdrawal Plan or similar affiliated or unaffiliated automated plans

- the following retirement plan distributions:

- lump-sum or other distributions from a qualified corporate or self-employed retirement plan following retirement (or following attainment of age 59 1/2 in the case of a "key employee" of a "top heavy" plan)

- distributions from an individual retirement account ("IRA") or Custodial Account under Section 403(b)(7) of the tax code, following attainment of age 59 1/2

The Fund also has the discretion to waive the 2.00% redemption fee if the Fund is in jeopardy of failing the 90% income test or losing its RIC qualification for tax purposes.

As described above, certain intermediaries do not assess redemption fees to certain categories of redemptions that do not present significant market timing concerns (such as automatic withdrawal plan redemptions). In these situations, the Fund's ability to assess redemption fees is generally limited by the intermediary's policies and, accordingly, no redemption fees will be assessed on such redemptions.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current


15

YOUR ACCOUNT

market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. The Fund's investments in foreign securities may be subject to foreign withholding taxes. You may be entitled to claim a credit or deduction with respect to foreign taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.95% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

FRED COPPER, a portfolio manager of Columbia Advisors, is the lead manager for the Fund and has co-managed the Fund since October, 2005.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as


18

MANAGING THE FUND

outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.


19

MANAGING THE FUND

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA ASSET ALLOCATION FUND
CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.


In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks a high total return by providing both a current level of income that is greater than that provided by popular stock market averages, as well as long-term growth in the value of the Fund's assets.

Current income includes both dividends from stocks and interest income from fixed income securities, after deducting Fund expenses.

PRINCIPAL INVESTMENT STRATEGIES

The Fund's investment advisor allocates the Fund's assets among various classes of equity and debt securities, including: large capitalization (large-cap) growth stocks, large-cap value stocks, middle capitalization (mid-cap) growth stocks, mid-cap value stocks, small capitalization (small-cap) growth stocks, small-cap value stocks, foreign securities, investment grade bonds, and non-investment grade bonds. Each asset class is managed by a separate portfolio manager or team with experience in investing in that particular class.

The Fund's lead portfolio manager will allocate the Fund's assets among the various asset classes. The lead portfolio manager will adjust the number of asset classes, as well as the portion of the Fund's assets allocated to each asset class, from time to time, based on his assessment of such factors as relative attractiveness, valuation, fundamentals, quantitative analyses and economic and market expectations.

In selecting equity securities, the advisor favors stocks with long-term growth potential that are expected to outperform their peers over time. The advisor also forecasts the direction and degree of change in long-term interest rates to help in the selection of debt securities. Investment grade debt securities purchased by the Fund will have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or will be unrated securities determined by the advisor to be of comparable quality. When deemed appropriate by the advisor, however, the Fund may invest up to 10% of its net assets in non-investment grade debt securities that are rated below BBB by S&P or Baa by Moody's or are unrated securities judged by the advisor to be of comparable quality (also known as "junk bonds"). The Fund keeps at least 25% of its total assets in fixed income investments, including debt securities and preferred stocks, at all times. The Fund may also participate in mortgage dollar rolls.

The Fund may invest up to 25% of its net assets in foreign securities.

The Fund may invest up to 10% of its net assets in exchange-traded funds, such as iShares/SM/. Exchange-traded funds are shares of investment companies which are traded like traditional equity securities on a national securities exchange or the NASDAQ(R) National Market System. iShares, which are traded on the American Stock Exchange, are shares of an investment company that invests substantially all of its assets in securities included in specified indices, including the Morgan Stanley Capital International indices for various countries and regions. The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor determines it is appropriate to revise the allocation of the Fund's assets between stocks and bonds. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

The Fund

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and nonhedging purposes, such as to adjust to the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.


3

The Fund

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

The Fund may invest in real estate investment trusts (REITs). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.


4

The Fund

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

The Fund may enter into a number of derivative strategies, including those that employ futures, options and foreign currencies, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust the Fund's sensitivity to changes in interest rates, or for other hedging purposes (i.e., attempting to offset a potential loss in one position by establishing an interest in an opposite position). Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been

The Fund

lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Standard & Poor's 500 Index (S&P Index), an unmanaged index that tracks the performance of 500 widely held, large-capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index (Lehman Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar denominated and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

The returns shown for Class A shares also include the returns of Retail A shares of the Galaxy Fund for periods prior to the inception of Prime A shares (November 1, 1998). Class A shares generally would have had substantially similar returns to Retail A shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Retail A shares.

(1) The returns for Class A and Class B shares include the returns of Prime A shares (for Class A shares) and Prime B shares (for Class B shares) of the Galaxy Fund for periods prior to November 18, 2002. The returns shown for Class A shares and Class B shares also include the returns of Retail A shares of the Galaxy Fund (adjusted, as necessary, to reflect the sales charges applicable to Class A shares and Class B shares, respectively), for periods prior to the inception of Prime A shares (November 1, 1998) and Prime B shares (November 1, 1998). Class A and Class B shares generally would have had substantially similar returns to Retail A shares because they would have been invested in the same portfolio of securities, although returns would have been lower to the extent that expenses for Class A and Class B shares exceed expenses paid by Retail A shares. The returns shown for Class C shares include the returns of Prime B shares of the Galaxy Fund (adjusted to reflect the sales charge applicable to Class C shares) for periods prior to November 18, 2002, the date on which Class C shares were initially offered by the Fund. The returns shown for Class C shares also include the returns of Retail A shares of the Galaxy Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to the date of inception of Prime B shares (November 1, 1998). Class C shares generally would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class C shares exceed expenses paid by Retail A and Prime B shares. Retail A shares of the Galaxy Fund were initially offered on December 30, 1991. Class A, B and C shares were initially offered on November 18, 2002.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years.

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.
(2) This charge applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares -- Class T, G and Z shares, exclusively to certain institutional and other investors. Class T, G and Z shares are made available through separate prospectuses provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

Your Account

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

Your Account

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Your Account

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Class C shares Your purchases of Class C shares are at Class C's net asset value.

The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares, as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the

advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single-round-trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.

UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and


23

Managing the Fund

other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiff's filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA ASSET ALLOCATION FUND
CLASS T AND G SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.


In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks a high total return by providing both a current level of income that is greater than that provided by popular stock market averages, as well as long-term growth in the value of the Fund's assets.

Current income includes both dividends from stocks and interest income from fixed income securities, after deducting Fund expenses.

PRINCIPAL INVESTMENT STRATEGIES

The Fund's investment advisor allocates the Fund's assets among various classes of equity and debt securities, including: large capitalization (large-cap) growth stocks, large-cap value stocks, middle capitalization (mid-cap) growth stocks, mid-cap value stocks, small capitalization (small-cap) growth stocks, small-cap value stocks, foreign securities, investment grade bonds, and non-investment grade bonds. Each asset class is managed by a separate portfolio manager or team with experience in investing in that particular class.

The Fund's lead portfolio manager will allocate the Fund's assets among the various asset classes. The lead portfolio manager will adjust the number of asset classes, as well as the portion of the Fund's assets allocated to each asset class, from time to time, based on his assessment of such factors as relative attractiveness, valuation, fundamentals, quantitative analyses and economic and market expectations.

In selecting equity securities, the advisor favors stocks with long-term growth potential that are expected to outperform their peers over time. The advisor also forecasts the direction and degree of change in long-term interest rates to help in the selection of debt securities. Investment grade debt securities purchased by the Fund will have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or will be unrated securities determined by the advisor to be of comparable quality. When deemed appropriate by the advisor, however, the Fund may invest up to 10% of its net assets in non-investment grade debt securities that are rated below BBB by S&P or Baa by Moody's or are unrated securities judged by the advisor to be of comparable quality (also known as "junk bonds"). The Fund keeps at least 25% of its total assets in fixed income investments, including debt securities and preferred stocks, at all times. The Fund may also participate in mortgage dollar rolls.

The Fund may invest up to 25% of its net assets in foreign securities.

The Fund may invest up to 10% of its net assets in exchange-traded funds, such as iShares/SM/. Exchange-traded funds are shares of investment companies which are traded like traditional equity securities on a national securities exchange or the NASDAQ(R) National Market System. iShares, which are traded on the American Stock Exchange, are shares of an investment company that invests substantially all of its assets in securities included in specified indices, including the Morgan Stanley Capital International indices for various countries and regions. The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor determines it is appropriate to revise the allocation of the Fund's assets between stocks and bonds. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and nonhedging purposes, such as to adjust to the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U. S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U. S. government. Furthermore, no assurances can be given that the U. S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

The Fund

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

The Fund may invest in real estate investment trusts (REITs). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

The Fund

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

The Fund may enter into a number of derivative strategies, including those that employ futures, options and foreign currencies, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust the Fund's sensitivity to changes in interest rates, or for other hedging purposes (i.e., attempting to offset a potential loss in one position by establishing an interest in an opposite position). Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted below, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Standard & Poor's 500 Index (S&P Index), an unmanaged index that tracks the performance of 500 widely held, large-capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index (Lehman Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar denominated and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The average annual total returns shown include the returns of Retail A shares (for Class T shares) and Retail B shares (for Class G shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A shares (adjusted to reflect sales charges applicable to Class G shares) for periods prior to the inception of Retail B shares of the Galaxy Fund (March 4, 1996). Retail A shares of the Galaxy Fund were initially offered on December 30, 1991. Class G shares generally would have had substantially similar returns to Retail A shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

(1) The Fund pays a management fee of 0.65% and an administration fee of 0.07%. Management fees have been restated to reflect contractual changes to the management fee effective November 1, 2004.
(2) The Fund may pay distribution and service (12b-1) fees up to a maximum of 1.15% of the Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services), but will limit such fees to an aggregate fee of not more than 0.95% during the current fiscal year.
(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.
(4) The Fund may pay shareholder service fees (which are included in other expenses) of up to a maximum of 0.50% of the Fund's average daily net assets attributable to Class T shares (comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services) but will limit such fees to an aggregate fee of not more than 0.30% during the current fiscal year.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Your Account

Class T and G shares are sold only to investors who received (and who have continuously held) Class T or G shares in connection with the merger of certain Galaxy Funds into various Columbia Funds (formerly named Liberty Funds).

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts


12

Your Account

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two round trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


16

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administrative support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia". You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


18

Your Account

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,


23

Managing the Fund

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiff's filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA ASSET ALLOCATION FUND
CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.


In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks a high total return by providing both a current level of income that is greater than that provided by popular stock market averages, as well as long-term growth in the value of the Fund's assets.


Current income includes both dividends from stocks and interest income from fixed income securities, after deducting Fund expenses.

PRINCIPAL INVESTMENT STRATEGIES

The Fund's investment advisor allocates the Fund's assets among various classes of equity and debt securities, including: large capitalization (large-cap) growth stocks, large-cap value stocks, middle capitalization (mid-cap) growth stocks, mid-cap value stocks, small capitalization (small-cap) growth stocks, small-cap value stocks, foreign securities, investment grade bonds, and non-investment grade bonds. Each asset class is managed by a separate portfolio manager or team with experience in investing in that particular class.

The Fund's lead portfolio manager will allocate the Fund's assets among the various asset classes. The lead portfolio manager will adjust the number of asset classes, as well as the portion of the Fund's assets allocated to each asset class, from time to time, based on his assessment of such factors as relative attractiveness, valuation, fundamentals, quantitative analyses and economic and market expectations.

In selecting equity securities, the advisor favors stocks with long-term growth potential that are expected to outperform their peers over time. The advisor also forecasts the direction and degree of change in long-term interest rates to help in the selection of debt securities. Investment grade debt securities purchased by the Fund will have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or will be unrated securities determined by the advisor to be of comparable quality. When deemed appropriate by the advisor, however, the Fund may invest up to 10% of its net assets in non-investment grade debt securities that are rated below BBB by S&P or Baa by Moody's or are unrated securities judged by the advisor to be of comparable quality (also known as "junk bonds"). The Fund keeps at least 25% of its total assets in fixed income investments, including debt securities and preferred stocks, at all times. The Fund may also participate in mortgage dollar rolls.

The Fund may invest up to 25% of its net assets in foreign securities.

The Fund may invest up to 10% of its net assets in exchange-traded funds, such as iShares/SM/. Exchange-traded funds are shares of investment companies which are traded like traditional equity securities on a national securities exchange or the NASDAQ(R) National Market System. iShares, which are traded on the American Stock Exchange, are shares of an investment company that invests substantially all of its assets in securities included in specified indices, including the Morgan Stanley Capital International indices for various countries and regions.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor determines it is appropriate to revise the allocation of the Fund's assets between stocks and bonds. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

The Fund

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and nonhedging purposes, such as to adjust to the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.


3

The Fund

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

The Fund may invest in real estate investment trusts (REITs). REITs are entities which either own properties or make construction or mortgage loans. REITs may also include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.


4

The Fund

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

The Fund may enter into a number of derivative strategies, including those that employ futures, options and foreign currencies, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust the Fund's sensitivity to changes in interest rates, or for other hedging purposes (i.e., attempting to offset a potential loss in one position by establishing an interest in an opposite position). Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Standard & Poor's 500 Index (S&P Index), an unmanaged index that tracks the performance of 500 widely held, large-capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index (Lehman Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar denominated and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc.

Your Account

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS
The Fund offers one class of shares in this

prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification number available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


13

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will


14

Your Account

not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.


15

Your Account

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other


20

Managing the Fund

things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiff's filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006

COLUMBIA LARGE CAP GROWTH FUND
CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

-------------------------------------------------------------------------------

INVESTMENT GOAL

The Fund seeks long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a broadly diversified portfolio of large-capitalization equity securities, primarily common stocks and securities that can be converted into common stocks. The Fund invests mainly in the securities of U.S. issuers, but may invest up to 20% of its total assets in foreign securities.


Growth stocks generally offer the
potential for strong revenue and
earnings, and accompanying capital
growth, with less dividend income than value stocks.

The Fund invests mainly in companies which the Fund's investment advisor believes will have faster earnings growth than the economy in general. The advisor looks for large-capitalization companies (generally over $5 billion) in growing industries, focusing on technological advances, good product development, strong management and other factors which support future growth. The advisor seeks out companies that have a history of strong earnings growth and are projected to continue a similar pattern of growth over the next three to five years.

The Fund may sell a portfolio security if there is an adverse change in the projected earnings growth of the company issuing the security. A security will also be sold when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

The Fund

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges./ /The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years./ /They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Growth Index ("Russell Index"), an unmanaged index that tracks the performance of those companies in the Russell Index with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

Calendar Year Total Returns (Class A)/(1)/

Best quarter: 4th quarter 1998, +23.93%
Worst quarter: 3rd quarter 2001, -17.16%

(1) The calendar year total returns shown for Class A shares include the returns of Prime A Shares of the Galaxy Equity Growth Fund (the Galaxy Fund), the predecessor to the Fund, for periods prior to November 18, 2002, the date on which Class A shares were initially offered by the Fund. The returns shown for Class A shares also include the returns of Retail A Shares of the Galaxy Fund for periods prior to the date of inception of Prime A Shares (November 1, 1998). Class A shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Retail A Shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Class A and Class B shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although returns would have been lower to the extent that expenses for Class A and Class B shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.
(2) This charge applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares -- Class T, G and Z shares, exclusively to certain institutional and other investors through separate prospectuses.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

Your Account

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase.
Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to


10

Your Account

that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder,


11

Your Account

certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Commission to financial advisors is 4.00%.

Automatic conversion to Class A shares occurs eight years after purchase.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in


15

Your Account

determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur


16

Your Account

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.


17

Your Account

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.


20

Managing the Fund

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006

COLUMBIA LARGE CAP GROWTH FUND
CLASS T AND G SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund
-------------------------------------------------------------------------------

INVESTMENT GOAL

The Fund seeks long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a broadly diversified portfolio of large-capitalization equity securities, primarily common stocks and securities that can be converted into common stocks. The Fund invests mainly in the securities of U.S. issuers, but may invest up to 20% of its total assets in foreign securities.

Growth stocks generally offer the potential for strong revenue and earnings, and accompanying capital growth, with less dividend income than value stocks.

The Fund invests mainly in companies which the Fund's investment advisor believes will have faster earnings growth than the economy in general. The advisor looks for large-capitalization companies (generally over $5 billion) in growing industries, focusing on technological advances, good product development, strong management and other factors which support future growth. The advisor seeks out companies that have a history of strong earnings growth and are projected to continue a similar pattern of growth over the next three to five years.

The Fund may sell a portfolio security if there is an adverse change in the projected earnings growth of the company issuing the security. A security will also be sold when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

The Fund

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges./ /The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years./ /They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges./ /

The Fund's returns are compared to the Russell 1000 Growth Index ("Russell Index"), an unmanaged index that tracks the performance of those companies in the Russell Index with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Retail A shares (for Class T shares) and Retail B shares (for Class G shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A shares (adjusted to reflect sales charges applicable to Class G shares) for periods prior to the inception of Retail B shares of the Galaxy Fund (March 4, 1996). Retail A shares were initially offered on December 14, 1990. Class G shares generally would have had substantially similar returns to Retail A shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T Sales Charges

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                     Commission %
Less than $3 million                     1.00

$3 million to less than $ 50 million     0.50
-------------------------------------------------
$50 million or more                      0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia

Your Account

fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


13

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Your Account

Distribution Options The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan in still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

Managing the Fund

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class T and G shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006

COLUMBIA LARGE CAP GROWTH FUND
CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOAL

The Fund seeks long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a broadly diversified portfolio of large-capitalization equity securities, primarily common stocks and securities that can be converted into common stocks. The Fund invests mainly in the securities of U.S. issuers, but may invest up to 20% of its total assets in foreign securities.


Growth stocks generally offer the potential for strong revenue and earnings, and accompanying capital growth, with less dividend income than value stocks.

The Fund invests mainly in companies which the Fund's investment advisor believes will have faster earnings growth than the economy in general. The advisor looks for large-capitalization companies (generally over $5 billion) in growing industries, focusing on technological advances, good product development, strong management and other factors which support future growth. The advisor seeks out companies that have a history of strong earnings growth and are projected to continue a similar pattern of growth over the next three to five years.

The Fund may sell a portfolio security if there is an adverse change in the projected earnings growth of the company issuing the security. A security will also be sold when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell 1000 Growth Index ("Russell Index"), an unmanaged index that tracks the performance of those companies in the Russell Index with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i)

Your Account

who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely

to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that


12

Your Account

are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.


13

Your Account

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in the principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.


16

Managing the Fund

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the Fund's last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the fiscal years ended September 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

The Fund's Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks long-term capital appreciation. Income is secondary to the objective of capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, mainly common stocks that the Fund's investment advisor believes are undervalued. The Fund may invest in companies of all sizes, but invests most of its assets in companies that have a market capitalization of more than $1.5 billion.

The Fund will typically hold a selection of common stocks consisting of stocks included in the Russell 1000 Value Index ("Russell Index"). The advisor tries to maintain a portfolio that matches the risk characteristics of the Russell Index. The advisor will, from time to time, vary the number and percentages of the Fund's holdings to try to provide higher returns than the Russell Index and to reduce the risk of underperforming the index over time. The Fund generally holds fewer stocks than the index and may hold securities that are not in the index.

Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

In selecting investments for the Fund, the advisor uses quantitative analysis to evaluate the attractiveness of each potential investment. The advisor may examine a wide variety of factors classified, for example, as value measures (forward price-to-earnings, trailing price-to-earnings, book value-to-price, price-to-cash flow, etc.), growth measures (earnings growth, revenue growth, etc.), price momentum and/or earnings momentum (earnings change, estimate revision, earnings surprise, etc.), among others.

The Fund seeks to hold a higher percentage of attractive investments than the index and a lesser percentage, or none, of less attractive investments. In all cases, investments are selected with the intention of increasing return relative to the Russell Index and/or reducing portfolio volatility relative to the Russell Index.

In addition, the advisor believes capital market inefficiencies may exist and may sometimes be exploited by using a variety of derivative instruments.

The advisor tries to control costs when it buys and sells securities for the Fund by using computerized systems called crossing networks that allow it to try to make trades at better prices and reduced commission rates.

The advisor may sell a stock when it believes other stocks in the index are more attractive investments, when the stock is removed from the index, or for other reasons.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.


2

The Fund

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.


3

The Fund

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Fund

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Value Index (Russell Index), an unmanaged index that tracks the performance of those companies in the Russell Index with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper Multi-Cap Value Funds Category (Lipper Average), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

Calendar Year Total Returns (Class A)/(1)/

LOGO

For the periods shown in bar chart:
Best quarter: 4th quarter 1998, +27.15%.
Worst quarter: 3rd quarter 2002, -21.36%.

(1) The calendar year total returns shown for Class A shares include returns of Retail A Shares of the Galaxy Equity Value Fund (the Galaxy Fund), the predecessor to the Fund, for the periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. Class A shares would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Retail A Shares.

The Fund

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of Retail A Shares (for Class A shares) and Retail B Shares (for Class B and Class C shares) of the Galaxy Fund for periods prior to November 25, 2002, the date on which Class A, B and C shares were initially offered by the Fund. The returns shown for Class B and Class C shares also include the performance of Retail A Shares of the Galaxy Fund for periods prior to the inception of Retail B Shares (March 4, 1996). Class B and Class C shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class B and Class C shares exceed expenses paid by Retail A Shares. The returns have not been restated to reflect any differences in expenses (such as 12b-1 fees) between any of the predecessor shares and the newer classes of shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares -- Class T, G and Z shares, exclusively to certain institutional and other investors through separate prospectuses.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES
Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.


11

Your Account

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Your Account

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


15

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


17

Your Account

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGER

Vikram J. Kuriyan, PhD, a portfolio manager of Columbia Advisors, is the manager for the Fund and has managed the Fund since June, 2005. Dr. Kuriyan has been associated with Columbia Advisors or its predecessors since January, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former


19

Managing the Fund

Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks long-term capital appreciation. Income is secondary to the objective of capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, mainly common stocks that the Fund's investment advisor believes are undervalued. The Fund may invest in companies of all sizes, but invests most of its assets in companies that have a market capitalization of more than $1.5 billion.

The Fund will typically hold a selection of common stocks consisting of stocks included in the Russell 1000 Value Index ("Russell Index"). The advisor tries to maintain a portfolio that matches the risk characteristics of the Russell Index. The advisor will, from time to time, vary the number and percentages of the Fund's holdings to try to provide higher returns than the Russell Index and to reduce the risk of underperforming the index over time. The Fund generally holds fewer stocks than the index and may hold securities that are not in the index.


Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

In selecting investments for the Fund, the advisor uses quantitative analysis to evaluate the attractiveness of each potential investment. The advisor may examine a wide variety of factors classified, for example, as value measures (forward price-to-earnings, trailing price-to-earnings, book value-to-price, price-to-cash flow, etc.), growth measures (earnings growth, revenue growth, etc.), price momentum and/or earnings momentum (earnings change, estimate revision, earnings surprise, etc.), among others.

The Fund seeks to hold a higher percentage of attractive investments than the index and a lesser percentage, or none, of less attractive investments. In all cases, investments are selected with the intention of increasing return relative to the Russell Index and/or reducing portfolio volatility relative to the Russell Index.

In addition, the advisor believes capital market inefficiencies may exist and may sometimes be exploited by using a variety of derivative instruments.

The advisor tries to control costs when it buys and sells securities for the Fund by using computerized systems called crossing networks that allow it to try to make trades at better prices and reduced commission rates.

The advisor may sell a stock when it believes other stocks in the index are more attractive investments, when the stock is removed from the index, or for other reasons.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

The Fund

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative

The Fund

transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Value Index (Russell Index), an unmanaged index that tracks the performance of those companies in the Russell Index with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper Multi-Cap Value Funds Category (Lipper Average), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G shares) of the Galaxy Fund for periods prior to November 25, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares), for periods prior to the inception of Retail B Shares of the Galaxy Fund (March 4, 1996). Retail A Shares were initially offered on September 1, 1988. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                                        Commission %

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be


10

Your Account

aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G Shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.


12

Your Account

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund


13

Your Account

will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administrative support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders


14

Your Account

by their financial advisors. The annual shareholder services fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


15

Your Account

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Your Account

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGER

Vikram J. Kuriyan, PhD, a portfolio manager of Columbia Advisors, is the manager for the Fund and has managed the Fund since June, 2005. Dr. Kuriyan has been associated with Columbia Advisors or its predecessors since January, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other


18

Managing the Fund

things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA DISCIPLINED VALUE FUND (THE "FUND")

CLASS Z SHARES

The Fund's Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks long-term capital appreciation. Income is secondary to the objective of capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities, mainly common stocks that the Fund's investment advisor believes are undervalued. The Fund may invest in companies of all sizes, but invests most of its assets in companies that have a market capitalization of more than $1.5 billion.

The Fund will typically hold a selection of common stocks consisting of stocks included in the Russell 1000 Value Index ("Russell Index"). The advisor tries to maintain a portfolio that matches the risk characteristics of the Russell Index. The advisor will, from time to time, vary the number and percentages of the Fund's holdings to try to provide higher returns than the Russell Index and to reduce the risk of underperforming the index over time. The Fund generally holds fewer stocks than the index and may hold securities that are not in the index.


Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

In selecting investments for the Fund, the advisor uses quantitative analysis to evaluate the attractiveness of each potential investment. The advisor may examine a wide variety of factors classified, for example, as value measures (forward price-to-earnings, trailing price-to-earnings, book value-to-price, price-to-cash flow, etc.), growth measures (earnings growth, revenue growth, etc.), price momentum and/or earnings momentum (earnings change, estimate revision, earnings surprise, etc.), among others.

The Fund seeks to hold a higher percentage of attractive investments than the index and a lesser percentage, or none, of less attractive investments. In all cases, investments are selected with the intention of increasing return relative to the Russell Index and/or reducing portfolio volatility relative to the Russell Index.

In addition, the advisor believes capital market inefficiencies may exist and may sometimes be exploited by using a variety of derivative instruments.

The advisor tries to control costs when it buys and sells securities for the Fund by using computerized systems called crossing networks that allow it to try to make trades at better prices and reduced commission rates.

The advisor may sell a stock when it believes other stocks in the index are more attractive investments, when the stock is removed from the index, or for other reasons.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.


2

The Fund

As part of its investment strategy, the Fund may buy and sell securities frequently. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Frequent trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.


3

The Fund

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell 1000 Value Index (Russell Index), an unmanaged index that tracks the performance of those companies in the Russell Index with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper Multi-Cap Value Funds Category (Lipper Average), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

Your Account

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur


13

Your Account

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.


14

Your Account

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGER

Vikram J. Kuriyan, PhD, a portfolio manager of Columbia Advisors, is the manager for the Fund and has managed the Fund since June, 2005. Dr. Kuriyan has been associated with Columbia Advisors or its predecessors since January, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD'') (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former


16

Managing the Fund

Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the Fund's last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the fiscal years ended September 30, 2005 and September 30, 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOAL

The Fund seeks to provide a relatively high total return through long-term capital appreciation and current income.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks. In addition, under normal market conditions, the Fund also invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies with large market capitalizations (generally over $2 billion) that the Fund's investment advisor believes offer attractive return potential from stock price appreciation and dividends.


A company's market capitalization is the price of a share of its stock, multiplied by the number of shares held by investors.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

The Fund

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges./ /The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years./ /They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both fund expenses and current sales charges.

Beginning in 2005, the Fund's benchmark was changed to the Russell 1000 Index (Russell 1000 Index), an unmanaged index that tracks the performance of 1000 of the largest U.S. companies, based on market capitalization. Previously, the Fund's returns were compared to the Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index that tracks the performance of 500 widely held large-capitalization U.S. stocks listed on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The advisor believes that the Russell 1000 Index, because of its broader market representation, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Russell 1000 Index, as well as the Fund's previous benchmark, the S&P 500 Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

For the periods shown in bar chart:
Best quarter: 4th quarter 1998, +20.82%
Worst quarter: 3rd quarter 2002, -19.00%

(1) The calendar year total returns shown for Class A shares for periods prior to December 9, 2002, the date on which Class A shares were initially offered by the Fund, include the returns of Prime A Shares of the Galaxy Growth & Income Fund (the Galaxy Fund), the predecessor to the Fund. The returns shown for Class A shares also include the returns of Retail A Shares for periods prior to the inception of Prime A Shares of the Galaxy Fund (November 1, 1998). Class A shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A shares exceed expenses paid by Retail A Shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The returns for Class A and Class B shares include the returns of Prime A Shares (for Class A shares) and Prime B Shares (for Class B shares) of the Galaxy Fund for periods prior to December 9, 2002, the date on which Class A and Class B shares were initially offered by the Fund. The returns shown for Class A shares and Class B shares also include the returns of Retail A Shares of the Galaxy Fund (adjusted, as necessary, to reflect the sales charge applicable to Class A shares and Class B shares, respectively) for periods prior to the date of inception of Prime A and Prime B Shares (November 1, 1998). Class A and Class B shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although returns would have been lower to the extent that expenses for Class A and Class B shares exceed expenses paid by Retail A Shares. The returns shown for Class C shares include the returns of Prime B Shares of the Galaxy Fund (adjusted to reflect the sales charge applicable to Class C shares) for periods prior to December 9, 2002, the date on which Class C shares were initially offered. The returns shown for Class C shares also include the returns of Retail A Shares of the Galaxy Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to the inception of Prime B Shares (November 1, 1998). Class C shares generally would have had substantially similar returns to Retail A and Prime B Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class C shares exceed expenses paid by Retail A and Prime B Shares. Retail A Shares were initially offered on February 12, 1993.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.
(2) This charge applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

(1) The Fund pays a management fee of 0.70% and an administration fee of 0.07%.
(2) The Fund may pay distribution and service (12b-1) fees up to a maximum of 0.35% of the Fund's average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder liaison services), but will limit such fees to an aggregate fee of not more than 0.25% for Class A shares during the current fiscal year.
(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.
(4) The Fund's Advisor has contractually agreed to bear a portion of the Fund's expenses so that the Fund's ordinary operating expenses (excluding any distribution and service fees, tax and interest expenses) do not exceed 0.89% until March 19, 2006. After this date the Advisor has agreed to continue this waiver on a voluntary basis. If the waiver were reflected in the table, Total Annual Fund Operating Expenses would be 1.14% for Class A, 1.89% for Class B and 1.89% for Class C. After March 19, 2006 this arrangement may be modified or terminated by the Advisor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares -- Class T, G and Z shares exclusively to certain institutional and other investors through separate prospectuses.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

Your Account

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost


10

Your Account

(i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with regard to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.


14

Your Account

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may


15

Your Account

be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

Your Account

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.


17

Your Account

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Jeffrey Huffman, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since August, 2005. Mr. Huffman has been associated with Columbia Advisors or its affiliates since March, 2000.

Guy W. Pope, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since March, 2005. Mr. Pope has been associated with Columbia Advisors or its predecessors since July, 1993.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see


19

Managing the Fund

below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

CLASS T AND G SHARES

The Fund's Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOAL

The Fund seeks to provide a relatively high total return through long-term capital appreciation and current income.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks. In addition, under normal market conditions, the Fund also invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies with large market capitalizations (generally over $2 billion) that the Fund's investment advisor believes offer attractive return potential from stock price appreciation and dividends.


A company's market capitalization is the price of a share of its stock, multiplied by the number of shares held by investors.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

The Fund

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing the changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

Beginning in 2005, the Fund's benchmark was changed to the Russell 1000 Index (Russell 1000 Index), an unmanaged index that tracks the performance of 1000 of the largest U.S. companies, based on market capitalization. Previously, the Fund's returns were compared to the Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index that tracks the performance of 500 widely held large-capitalization U.S. stocks listed on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The advisor believes that the Russell 1000 Index, because of its broader market representation, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Russell 1000 Index, as well as the Fund's previous benchmark, the S&P 500 Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G shares) of the Galaxy Fund for periods prior to December 9, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares for periods prior to the inception of Retail B Shares of the Galaxy Fund (March 4, 1996). Retail A Shares were initially offered on February 12, 1993. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

(1) The Fund pays a management fee of 0.70% and an administration fee of 0.07%.
(2) The Fund may pay shareholder service fees (which are included in other expenses) up to a maximum of 0.50% of the Fund's average daily net assets attributable to Class T shares (comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services), but will limit such fees to an aggregate fee of not more than 0.30% during the current fiscal year.
(3) The Fund may pay distribution and service (12b-1) fees up to a maximum of 1.15% of the Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services), but will limit such fees to an aggregate fee of not more than 0.95% during the current fiscal year.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.
(5) The Fund's Advisor has contractually agreed to bear a portion of the Fund's expenses so that the Fund's ordinary operating expenses (excluding any distribution and service fees, tax and interest expenses) do not exceed 0.89% until March 19, 2006. After this date the Advisor has agreed to continue this waiver on a voluntary basis. If the waiver were reflected in the table, Total Annual Fund Operating Expenses would be 1.84% for Class G and 1.19% for Class T. After March 19, 2006 this arrangement may be modified or terminated by the Advisor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class T and G shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Class T and G shares are sold only to investors who received (and who have continuously held) Class T or G shares in connection with the merger of certain Galaxy Funds into various Columbia Funds (formerly named Liberty Funds).

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T Sales Charges

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


13

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administrative support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value) your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Your Account

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Jeffrey Huffman, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since August, 2005. Mr. Huffman has been associated with Columbia Advisors or its affiliates since March, 2000.

Guy W. Pope, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since March, 2005. Mr. Pope has been associated with Columbia Advisors or its predecessors since July, 1993.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,

Managing the Fund

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

CLASS Z SHARES

The Fund's Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOAL

The Fund seeks to provide a relatively high total return through long-term capital appreciation and current income.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks. In addition, under normal market conditions, the Fund also invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies with large market capitalizations (generally over $2 billion) that the Fund's investment advisor believes offer attractive return potential from stock price appreciation and dividends.


A company's market capitalization is the price of a share of its stock, multiplied by the number of shares held by investors.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of an actual or expected deterioration in the performance of the security or in the financial condition of the issuer of the security.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

The Fund

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares./ /The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

Beginning in 2005, the Fund's benchmark was changed to the Russell 1000 Index (Russell 1000 Index), an unmanaged index that tracks the performance of 1000 of the largest U.S. companies, based on market capitalization. Previously, the Fund's returns were compared to the Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index that tracks the performance of 500 widely held large-capitalization U.S. stocks listed on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The advisor believes that the Russell 1000 Index, because of its broader market representation, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Russell 1000 Index, as well as the Fund's previous benchmark, the S&P 500 Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management

Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc. ;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


11

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.


12

Your Account

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

                for a 12-month period or less.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Jeffrey Huffman, a portfolio manager of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since August, 2005. Mr. Huffman has been associated with Columbia Advisors or its affiliates since March, 2000.

Guy W. Pope, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since March, 2005. Mr. Pope has been associated with Columbia Advisors or its predecessors since July, 1993.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see

Managing the Fund

below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOAL

The Fund seeks to provide long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests mainly in the common stocks of small companies that the Fund's investment advisor believes are undervalued. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. issuers, but may invest up to 20% of its total assets in foreign equity securities. In selecting portfolio securities for the Fund, the advisor looks at the underlying strength of companies, their products, their competitive positions and the quality of their management. It also performs research to attempt to identify companies likely to benefit from emerging industry trends and potential market recoveries. A portfolio security may be sold if the advisor determines that it is no longer undervalued or if there has been a deterioration in the performance of the security or in the financial condition of the issuer.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.


2

The Fund

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

The Fund


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies based on market capitalization. The Fund's returns are also compared to the Standard & Poor's SmallCap 600 Composite Index (S&P SmallCap 600), an unmanaged index that tracks the performance of 600 domestic companies traded on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The S&P SmallCap 600 is heavily weighted with the stocks of companies with small market capitalizations. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Prime A Shares of the Galaxy Small Cap Value Fund (Galaxy Fund), the predecessor to the Fund, for periods prior to November 18, 2002, the date on which Class A shares were initially offered by the Fund. The returns shown for Class A shares also include the returns of Retail A Shares of the Galaxy Fund for periods prior to the inception of Prime A Shares (November 1, 1998). Class A shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Retail A Shares.

The Fund

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Prime A Shares (for Class A shares) and Prime B Shares (for Class B shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class A and Class B shares were initially offered by the Fund. The returns shown for Class A shares and Class B shares also include the returns of Retail A Shares of the Galaxy Fund (adjusted, as necessary, to reflect the sales charges applicable to Class A shares and Class B shares, respectively) for periods prior to the date of inception of Prime A and Prime B Shares (November 1, 1998). Class A and Class B shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although returns would have been lower to the extent that expenses for Class A and Class B shares exceed expenses paid by Retail A Shares. The returns shown for Class C shares include the returns of Retail B Shares of the Galaxy Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to November 18, 2002, the date on which Class C shares were initially offered by the Fund. The returns shown for Class C shares also include the returns of Retail A Shares of the Galaxy Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to the date of inception of Retail B Shares (November 1, 1998). Class C shares generally would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class C shares exceed expenses paid by Retail A and Retail B Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.
(2) This charge applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

HOW TO BUY SHARES

Effective March 1, 2004, the Fund is closed to both new investors and new accounts. Shareholders who have opened and funded an account with the Fund as of February 27, 2004 (i) may continue to make additional purchases in their accounts, (ii) may continue to reinvest dividends and capital gain distributions, and (iii) are allowed to open new accounts resulting from the transfer of existing assets in the Fund. All retirement plans that are held at the plan level and discretionary wrap programs that invest with the Fund and trade on an omnibus basis which are invested in the Fund prior to March 1, 2004, may continue to make additional investments. Certain retirement plans may require additional time to fund their accounts due to operational constraints. Those retirement plans must have chosen the Fund as an investment option prior to February 1, 2004 and must be funded by April 5, 2004 in order to continue to make additional purchases in their accounts.

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Automated dollar You may purchase shares of the Fund for your account by
cost averaging   exchanging $100 or more each month from another fund for
                 shares of the same class of the Fund at no additional cost.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares, Class T, G and Z shares, exclusively to certain institutional and other investors. Class T, G and Z shares are made available through separate prospectuses provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00

$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for


11

Your Account

which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares, as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


14

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in


15

Your Account

determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur

Your Account

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Your Account

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.69% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Peter Larson, a senior vice president of Columbia Advisors, is the lead manager for the Fund and has managed the Fund, including the predecessor funds, since it commenced operations in 1992. Mr. Larson has been associated with Columbia Advisors or its predecessors since 1963.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


19

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

Managing the Fund

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INT-47/107869-0306 March 27, 2006


Effective March 1, 2004, the Fund is closed to both new investors and new accounts. For more information, see the section entitled "How to Buy Shares."

Class T and G shares are sold only to investors who received (and who have continuously held) Class T or G shares in connection with the merger of certain Galaxy Funds into various Columbia Funds (formerly named Liberty Funds).

Although these securities have been registered with the Securities and Exchange Commission, the Commission has not approved or disapproved any shares offered in this prospectus or determined whether this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The Fund
-------------------------------------------------------------------------------

INVESTMENT GOAL

The Fund seeks to provide long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests mainly in the common stocks of small companies that the Fund's investment advisor believes are undervalued. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. issuers, but may invest up to 20% of its total assets in foreign equity securities. In selecting portfolio securities for the Fund, the advisor looks at the underlying strength of companies, their products, their competitive positions and the quality of their management. It also performs research to attempt to identify companies likely to benefit from emerging industry trends and potential market recoveries. A portfolio security may be sold if the advisor determines that it is no longer undervalued or if there has been a deterioration in the performance of the security or in the financial condition of the issuer.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and

The Fund

developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

The Fund


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies based on market capitalization. The Fund's returns are also compared to the Standard & Poor's SmallCap 600 Composite Index (S&P SmallCap 600), an unmanaged index that tracks the performance of 600 domestic companies traded on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The S&P SmallCap 600 is heavily weighted with the stocks of companies with small market capitalizations. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares) for periods prior to the inception of Retail B Shares of the Galaxy Fund (November 1, 1998). Retail A Shares were initially offered on February 12, 1993. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

HOW TO BUY SHARES

Effective March 1, 2004, the Fund is closed to both new investors and new accounts. Shareholders who have opened and funded an account with the Fund as of February 27, 2004 (i) may continue to make additional purchases in their accounts, (ii) may continue to reinvest dividends and capital gain distributions, and (iii) are allowed to open new accounts resulting from the transfer of existing assets in the Fund. All retirement plans that are held at the plan level and discretionary wrap programs that invest with the Fund and trade on an omnibus basis which are invested in the Fund prior to March 1, 2004, may continue to make additional investments. Certain retirement plans may require additional time to fund their accounts due to operational constraints. Those retirement plans must have chosen the Fund as an investment option prior to February 1, 2004 and must be funded by April 5, 2004 in order to continue to make additional purchases in their accounts.

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class T and G shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Class T and G shares are sold only to investors who received (and who have continuously held) Class T or G shares in connection with the merger of certain Galaxy Funds into various Columbia Funds (formerly named Liberty Funds).

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


13

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fees for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisor. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after a certain number of years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


15

Your Account

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

Managing the Fund

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Information for Class T shares and Class G shares prior to November 18, 2002, the date of reorganization, is for the former Retail A shares and Retail B shares, respectively, of the Galaxy Small Cap Value Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the years ended September 30, 2005 and September 30, 2004 have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003 and for the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA SMALL CAP CORE FUND
CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the


judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INT-47/107779-0306 March 27, 2006


Effective March 1, 2004, the Fund is closed to both new investors and new accounts. For more information, see the section entitled "How to Buy Shares."

INVESTMENT GOAL

The Fund seeks to provide long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests mainly in the common stocks of small companies that the Fund's investment advisor believes are undervalued. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. issuers, but may invest up to 20% of its total assets in foreign equity securities. In selecting portfolio securities for the Fund, the advisor looks at the underlying strength of companies, their products, their competitive positions and the quality of their management. It also performs research to attempt to identify companies likely to benefit from emerging industry trends and potential market recoveries. A portfolio security may be sold if the advisor determines that it is no longer undervalued or if there has been a deterioration in the performance of the security or in the financial condition of the issuer.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.


2

The Fund

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

The Fund


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses. Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.
The Fund's returns are compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies based on market capitalization. The Fund's returns are also compared to the Standard & Poor's SmallCap 600 Composite Index (S&P SmallCap 600), an unmanaged index that tracks the performance of 600 domestic companies traded on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The S&P SmallCap 600 is heavily weighted with the stocks of companies with small market capitalizations. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

HOW TO BUY SHARES

Effective March 1, 2004, the Fund is closed to both new investors and new accounts. Shareholders who have opened and funded an account with the Fund as of February 27, 2004 (i) may continue to make additional purchases in their accounts, (ii) may continue to reinvest dividends and capital gain distributions, and (iii) are allowed to open new accounts resulting from the transfer of existing assets in the Fund. All retirement plans that are held at the plan level and discretionary wrap programs that invest with the Fund and trade on an omnibus basis which are invested in the Fund prior to March 1, 2004, may continue to make additional investments. Certain retirement plans may require additional time to fund their accounts due to operational constraints. Those retirement plans must have chosen the Fund as an investment option prior to February 1, 2004 and must be funded by April 5, 2004 in order to continue to make additional purchases in their accounts.

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with Columbia Management Services, Inc. or your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;


8

Your Account

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc. ;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to the frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


11

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will


12

Your Account

not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.

                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer


13

Your Account

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.69% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Peter Larson, a senior vice president of Columbia Advisors, is the lead manager for the Fund and has managed the Fund, including the predecessor funds, since it commenced operations in 1992. Mr. Larson has been associated with Columbia Advisors or its predecessors since 1963.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and

Managing the Fund

certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions).

The information for the period ended September 30, 2003 and for the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOAL

The Fund seeks capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Growth Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. companies, but may invest up to 20% of its total assets in foreign equity securities.

In selecting investments for the Fund, the Fund's investment advisor looks for promising industries. It then looks within those industries for what it judges to be reasonably priced companies that have above-average growth potential. The advisor consults a wide range of sources, including management, competitors, other industry sources and regional brokerage analysts.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of a deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.


2

The Fund

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

The Fund


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

Beginning in 2003, the Fund's primary benchmark was changed to the Russell 2000 Growth Index, an unmanaged index that tracks the performance of those Russell 2000 companies with higher price-to-book ratios and higher forecasted growth values. The Fund's returns are also compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies, based on market capitalization. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Retail A Shares of the Galaxy Small Company Equity Fund (Galaxy Fund), the predecessor to the Fund, for periods prior to November 18, 2002, the date on which Class A shares were initially offered by the Fund. Class A shares would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Retail A Shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of Retail A Shares (for Class A shares) and Retail B Shares (for Class B and Class C shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class A, B and C shares were initially offered by the Fund. The returns of Class B and Class C shares also include the returns of Retail A Shares for periods prior to the inception of Retail B Shares of the Galaxy Fund (March 4, 1996). Class B and Class C shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class B and Class C shares exceed expenses paid by Retail A Shares. The returns have not been restated to reflect any differences in expenses between the predecessor shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares, Class T, G and Z shares, exclusively to certain institutional and other investors. Class T, G and Z shares are made available through separate prospectuses provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00

$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES
Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

Your Account

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares, as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the


12

advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.


14

Your Account

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25%. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight of years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may


15

Your Account

be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

Your Account

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Your Account

distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

Managing the Fund

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA SMALL COMPANY EQUITY FUND
CLASS T AND G SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the


judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOAL

The Fund seeks capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Growth Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. companies, but may invest up to 20% of its total assets in foreign equity securities.

In selecting investments for the Fund, the Fund's investment advisor looks for promising industries. It then looks within those industries for what it judges to be reasonably priced companies that have above-average growth potential. The advisor consults a wide range of sources, including management, competitors, other industry sources and regional brokerage analysts.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of a deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

The Fund

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Frequent trading risk Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

Beginning in 2003, the Fund's primary benchmark was changed to the Russell 2000 Growth Index, an unmanaged index that tracks the performance of those Russell 2000 companies with higher price-to-book ratios and higher forecasted growth values. The Fund's returns are also compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies, based on market capitalization. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G shares) of the Galaxy Fund for periods prior to November 18, 2002, the date on which Class T and Class G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares) for periods prior to the inception of Retail B Shares of the Galaxy Fund (March 4, 1996). Retail A Shares were initially offered on December 30, 1991. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

(3) The Fund may pay shareholder service fees (which are included in other expenses) up to a maximum of 0.50% of the Fund's average daily net assets attributable to Class T shares (comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative services), but will limit such fees to an aggregate fee of not more than 0.30% during the current fiscal year.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00

$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts


9

Your Account

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Commission to financial advisors is 4.00%.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund


12

Your Account

will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders


13

Your Account

by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after a certain number of years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


14

Your Account

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.


15

Your Account

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions may also be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the


18

Managing the Fund

funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Information for Class T shares and Class G shares prior to November 18, 2002, the date of reorganization, is for the former Retail A shares and Retail B shares, respectively, of the Galaxy Small Company Equity Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the years ended September 30, 2005 and September 30, 2004 have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003 and for the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA SMALL COMPANY EQUITY FUND
CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the


judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOAL

The Fund seeks capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Growth Index. As of December 31, 2005, that index included companies with capitalizations between approximately $3 million and $4.39 billion. All market capitalizations are determined at the time of purchase. The Fund invests primarily in the common stock of U.S. companies, but may invest up to 20% of its total assets in foreign equity securities.

In selecting investments for the Fund, the Fund's investment advisor looks for promising industries. It then looks within those industries for what it judges to be reasonably priced companies that have above-average growth potential. The advisor consults a wide range of sources, including management, competitors, other industry sources and regional brokerage analysts.

The Fund will sell a portfolio security when, as a result of changes in the economy, the advisor believes that holding the security is no longer consistent with the Fund's investment goal. A security may also be sold as a result of a deterioration in the performance of the security or in the financial condition of the issuer of the security.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

The Fund

and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses. Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.
Beginning in 2003, the Fund's primary benchmark was changed to the Russell 2000 Growth Index, an unmanaged index that tracks the performance of those Russell 2000 companies with higher price-to-book ratios and higher forecasted growth values. The Fund's returns are also compared to the Russell 2000 Index, an unmanaged index that tracks the performance of the 2,000 smallest of the 3,000 largest U.S. companies, based on market capitalization. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

"Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of Fund shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund except as noted below with respect to orders received through omnibus accounts, in any 28-day period, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.


11

Your Account

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.


12

Your Account

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends annually and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS
On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratios used for the Fund, which is the same as those stated in the Annual Fund Operating Expenses table, are presented in the chart, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA DIVIDEND INCOME FUND
(THE "FUND")

CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could


increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose.


On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

2. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

3. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

The Fund

INVESTMENT GOAL

The Fund seeks current income and capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of income-producing (dividend-paying) equity securities, which will consist primarily of common stocks but may also include preferred stocks and convertible securities. The Fund's investment advisor looks for investments that it believes offer prospects for dividend growth and capital appreciation.

The Fund generally will emphasize value stocks, but may purchase growth securities when such securities pay dividends or the advisor believes such securities have particularly good prospects for capital appreciation. In addition to equity securities, the Fund may also invest up to 20% of its net assets in debt securities, including lower-quality debt securities. The Fund may invest up to 20% of its net assets in securities of foreign issuers.

Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

Growth stocks generally offer the potential for strong revenue and earnings, and accompanying capital growth, with less dividend income than value stocks.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values


2

The Fund

of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Medium-quality debt securities. Medium-quality debt securities, although considered investment grade, may have some speculative characteristics.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more


3

The Fund

limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance, over the past one-year, five-year and life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Value Index, an unmanaged index that tracks the performance of those Russell 1000 Index companies with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

Calendar Year Total Returns (Class A)/(1)/

For the periods shown in bar chart:
Best quarter: 2nd quarter 2003, +18.41%
Worst quarter: 3rd quarter 2002, -19.80%

(1) The bar chart total returns shown are for Class A shares and include the returns of the Fund's Class T shares, which include the returns of Retail A Shares of the Galaxy Strategic Equity Fund (the Galaxy Fund), the predecessor to the Fund, for periods prior to November 25, 2002. Class T shares are not offered in this prospectus. Class A shares would have had substantially similar annual returns because they are invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares exceed expenses paid by Class T shares. On October 27, 2003, the investment policies of the Fund (formerly known as Columbia Strategic Equity Fund) were modified. As a result, the Fund's performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class T shares (for Class A) and Class G shares (for Class B and Class C) for periods prior to November 25, 2002, the date on which Class A, B and C shares were initially offered by the Fund. The returns shown for Class T and G shares include the returns of Retail A Shares (for Class T) and Retail B Shares (for Class G) of the Galaxy Fund for periods prior to November 25, 2002, the date on which Class T and G shares were initially offered by the Fund. The returns have not been restated to reflect any differences in expenses between the predecessor shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. On October 27, 2003, the investment policies of the Fund (formerly known as Columbia Strategic Equity Fund) were modified. As a result, the Fund's performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.

The Fund

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expense table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) The Fund pays a management fee of 0.70% and an administrative fee of 0.07%.
(2) The Fund may pay distribution and service (12b-1) fees up to a maximum of 0.35% of the Fund's average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder liaison services) but will limit such fees to an aggregate of not more than 0.25% for Class A shares during the current fiscal year.
(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.
(4) The Fund's Advisor has contractually agreed to bear a portion of the Fund's expenses so that the Fund's ordinary operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) do not exceed 0.80% annually through January 31, 2007.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documents it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares -- Classes T, G and Z shares, exclusively to certain institutional and other investors. Class T and G and Class Z shares are available through separate prospectuses provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Your Account

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $ 1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions gains are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost


11

Your Account

(i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to


12

Your Account

waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are made at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Commission to financial advisors is 4.00%.

Automatic conversion to Class A shares occurs eight years after purchase.

Class C shares Your purchases of Class C shares are made at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policies. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


15

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The Fund's Board of Trustees currently limits total payments under the Rule 12b-1 plan for Class A shares to 0.25% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to


16

Your Account

promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.


17

Your Account

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer


18

Your Account

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Scott L. Davis, vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since November 2001. Mr. Davis has been associated with Columbia Advisors or its predecessors since 1985.

Richard Dahlberg, managing director and head of Columbia Advisors' Income Strategies team, is a co-manager of the Fund and has co-managed the Fund since October 2003. Mr. Dahlberg has been associated with Columbia Advisors or its predecessors since September 2003. Prior to joining Columbia Advisors in September, 2003, Mr. Dahlberg was with Grantham, Mayo, Van Otterloo & Co. LLC from November 2001 to December 2002 and with Pioneer Investment Management, Inc. from September 1998 to November 2001.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud


20

Managing the Fund

provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.


21

Managing the Fund

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA DIVIDEND INCOME FUND
(THE "FUND")

CLASS T AND G SHARES

The Prospectus is hereby supplemented with the following information:

1. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could


increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose.


On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

2. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

3. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

The Fund

INVESTMENT GOAL

The Fund seeks current income and capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of income-producing (dividend-paying) equity securities, which will consist primarily of common stocks but may also include preferred stocks and convertible securities. The Fund's investment advisor looks for investments that it believes offer prospects for dividend growth and capital appreciation.

The Fund generally will emphasize value stocks, but may purchase growth securities when such securities pay dividends or the advisor believes such securities have particularly good prospects for capital appreciation. In addition to equity securities, the Fund may also invest up to 20% of its net assets in debt securities, including lower-quality debt securities. The Fund may invest up to 20% of its net assets in securities of foreign issuers.


Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

Growth stocks generally offer the potential for strong revenue and earnings, and accompanying capital growth, with less dividend income than value stocks.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values


2

The Fund

of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Medium-quality debt securities. Medium-quality debt securities, although considered investment grade, may have some speculative characteristics.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more


3

The Fund

limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges./ /The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and the life of the Fund./ /The chart and table are intended to illustrate some of the risks of investing in the Fund by showing the changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Value Index, an unmanaged index that tracks the performance of those Russell 1000 Index companies with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

As a result, the Fund's performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

(2) This charge applies only to certain Class T shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

(2) The Fund may pay shareholder service fees (which are included in other expenses) up to a maximum of 0.50% of such Fund's daily net assets attributable to Class T shares (comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative services), but will limit such fees to an aggregate fee of not more than 0.30% during the current fiscal year.
(3) The Fund may pay distribution and service (12b-1) fees up to a maximum of 1.15% of the Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services), but will limit such fees to an aggregate fee not more than 0.95% during the current fiscal year.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application is complete, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class T Sales Charges

                                                      % of offering

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts
. Joint accounts
. Certain IRA accounts
. Certain trusts
. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

Your Account

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depends on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class G shares Your purchases of Class G shares are made at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group Plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Commission to financial advisors is 4.00%.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account number and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" also means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


13

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fees for shareholder liaison services and administrative support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.95% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisor. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.30% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

Your Account

Additional Intermediary Compensation In addition to the commission specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.


15

Your Account

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value) your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Your Account

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

Scott L. Davis, vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since November 2001. Mr. Davis has been associated with Columbia Advisors or its predecessors since 1985.

Richard Dahlberg, managing director and head of Columbia Advisors' Income Strategies team, is a co-manager of the Fund and has co-managed the Fund since October 2003. Mr. Dahlberg has been associated with Columbia Advisors or its predecessors since September 2003.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,


18

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006 (THE "PROSPECTUS")

COLUMBIA DIVIDEND INCOME FUND
(THE "FUND")

CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could


increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose.


On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOAL

The Fund seeks current income and capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of income-producing (dividend-paying) equity securities, which will consist primarily of common stocks but may also include preferred stocks and convertible securities. The Fund's investment advisor looks for investments that it believes offer prospects for dividend growth and capital appreciation.

The Fund generally will emphasize value stocks, but may purchase growth securities when such securities pay dividends or the advisor believes such securities have particularly good prospects for capital appreciation. In addition to equity securities, the Fund may also invest up to 20% of its net assets in debt securities, including lower-quality debt securities. The Fund may invest up to 20% of its net assets in securities of foreign issuers.

Value stocks are stocks that appear to be underpriced based on measures such as lower price-to-earnings, price-to-book value and price-to-earnings growth ratios.

Growth stocks generally offer the potential for strong revenue and earnings, and accompanying capital growth, with less dividend income than value stocks.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values


2

The Fund

of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Medium-quality debt securities. Medium-quality debt securities, although considered investment grade, may have some speculative characteristics.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day-to-day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Convertible securities are securities that can be converted into common stock, such as certain debt securities and preferred stock. Convertible securities are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to market risk.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more


3

The Fund

limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing the changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and life of the Fund periods. They include the effects of Fund expenses./(1)/

The Fund's returns are compared to the Russell 1000 Value Index, an unmanaged index that tracks the performance of those Russell 1000 Index companies with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The average annual total returns shown include returns of Trust Shares of the Galaxy Fund for periods prior to November 25, 2002, the date on which Class Z shares were initially offered by the Fund. Trust Shares were initially offered by the Galaxy Fund on March 4, 1998. On October 27, 2003, the investment policies of the Fund (formerly known as Columbia Strategic Equity Fund) were modified. As a result, the Fund's performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.

As a result, the Fund's performance for periods prior to that date may not be representative of the performance it would have achieved had its current investment policies been in place.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions.
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

(3) The Fund's Advisor has contractually agreed to bear a portion of the Fund's expenses so that the Fund's ordinary operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) do not exceed 0.80% annually through January 31, 2007.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price.
"Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accents, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-


13

Your Account

transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value) your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined by the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.70% of average daily net assets of the Fund.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


16

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including


17

Managing the Fund

claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgment. The plaintiffs filed a notice of appeal on December 30, 2005.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Information for Class Z shares prior to November 25, 2002, the date of reorganization, is for the former Trust shares of the Galaxy Strategic Equity Fund. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the years ended September 30, 2005 and 2004 have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003, and the fiscal years ended October 31, 2002, 2001 and 2000, have been audited by another independent registered public accounting firm, whose report, expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

CLASS A, B AND C SHARES
(REPLACING SUPPLEMENT DATED FEBRUARY 17, 2006)

The Prospectus is hereby supplemented with the following information:

1. The second paragraph in the section "PRINCIPAL INVESTMENT STRATEGIES" under the heading "THE FUND" is revised in its entirety as follows:

The Fund's investments are diversified among industries and market sectors including, but not limited to, technology, financial services, health care, and global consumer franchise sectors. The Fund may invest up to 20% of its total assets in foreign securities. To select investments for the Fund, the Fund's investment advisor considers companies that it believes will generate earnings growth over the long term regardless of the economic environment.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32


million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.


On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in large capitalization ("large-cap") stocks. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the Russell 1000 Growth Index. As of December 31, 2005, that index included companies with capitalizations between approximately $702 million and $370.3 billion. All market capitalizations are determined at the time of purchase.

The Fund's investments are diversified among industries and market sectors including, but not limited to, technology, financial services, health care, and global consumer franchise sectors. The Fund may invest up to 25% of its total assets in foreign stocks. To select investments for the Fund, the Fund's investment advisor considers companies that it believes will generate earnings growth over the long term regardless of the economic environment.

The advisor may sell a portfolio holding if, among other reasons, the security reaches the advisor's price target or if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) that could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.


2

THE FUND

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 1000 Growth Index ("Russell Index"), an unmanaged index that measures the performance of those Russell 1000 Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on July 15, 2002, and Class Z shares were initially offered on July 1, 1958.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class Z shares (the oldest existing Fund class) for periods prior to their inception (adjusted to reflect the sales charges applicable to Class A, Class B and Class C, respectively). These returns have not been restated to reflect any differences in expenses (such as 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A, Class B and Class C shares were initially offered on July 15, 2002, and Class Z shares were initially offered on July 1, 1958.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

(2) Other expenses have been restated to reflect contractual changes to the transfer agency fees and pricing and bookkeeping fees for the Fund effective November 1, 2005.

(3) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class A shares. If this waiver were reflected in the table the 12b-1 fee for Class A shares would be 0.30% and total annual fund operating expenses for Class A shares would be 1.34%. This arrangement may be modified or terminated by the distributor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

YOUR ACCOUNT

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.


13

YOUR ACCOUNT

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-l that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Class A share distribution fee so that it does not exceed 0.05% annually. This arrangement may be modified or terminated by the distributor at any time. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

MANAGING THE FUND

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year-to-year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although, to a limited extent, it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

CLASS Z SHARES
(REPLACING SUPPLEMENT DATED FEBRUARY 17, 2006)

The Prospectus is hereby supplemented with the following information:

1. The second paragraph in the section "PRINCIPAL INVESTMENT STRATEGIES" under the heading "THE FUND" is revised in its entirety as follows:

The Fund's investments are diversified among industries and market sectors including, but not limited to, technology, financial services, health care, and global consumer franchise sectors. The Fund may invest up to 20% of its total assets in foreign securities. To select investments for the Fund, the Fund's investment advisor considers companies that it believes will generate earnings growth over the long term regardless of the economic environment.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32


million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.


On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in large capitalization ("large-cap") stocks. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the Russell 1000 Growth Index. As of December 31, 2005, that index included companies with capitalizations between approximately $702 million and $370.3 billion. All market capitalizations are determined at the time of purchase.

The Fund's investments are diversified among industries and market sectors including, but not limited to, technology, financial services, health care, and global consumer franchise sectors. The Fund may invest up to 25% of its total assets in foreign stocks. To select investments for the Fund, the Fund's investment advisor considers companies that it believes will generate earnings growth over the long term regardless of the economic environment.

The advisor may sell a portfolio holding if, among other reasons, the security reaches the advisor's price target or if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) that could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.


2

THE FUND

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell 1000 Growth Index ("Russell Index"), an unmanaged index that measures the performance of those Russell 1000 Index companies with higher price-to-book ratios and higher forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with Columbia Management Services, Inc. or your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity.

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

YOUR ACCOUNT

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

YOUR ACCOUNT

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- CLASS A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.


11

YOUR ACCOUNT

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

YOUR ACCOUNT

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.


13

YOUR ACCOUNT

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

current fund

14

YOUR ACCOUNT

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

LEGAL PROCEEDINGS


On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").


17

MANAGING THE FUND

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year-to-year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although, to a limited extent, it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

CLASS A, B AND C SHARES

1. The section under the heading "MANAGING THE FUND; PORTFOLIO MANAGER" is revised and replaced in its entirety with the following:

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC


Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.


On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in common stocks believed to have long-term growth potential. Under normal market conditions, the Fund invests at least 80% of its total assets in common stocks. The Fund may invest in companies of any size, ranging from small-cap companies to large-cap companies and the Fund's investments are diversified among industries and market sectors. The Fund seeks to invest in companies that produce products or provide services that the advisor believes children or teenagers use, are aware of, or have an interest in. Examples of these types of industries and market sectors include, but are not limited to, apparel and footwear, entertainment, retail, computer and electronics, Internet service providers, financial services and personal care products.

The Fund may invest up to 33% of its assets in foreign stocks including American Depositary Receipts. The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts ("derivatives").

In selecting securities for the Fund, the Fund's investment advisor begins with a top-down industry sector analysis tracking specific sectors or industries of the market and identifying securities within those areas that are expected to reward shareholders. Through this process, the advisor determines the emphasis to be placed on different industries and selects individual stocks in which the Fund invests. In building the Fund's portfolio, the advisor combines this top-down approach with intensive bottom-up research of individual securities issues, evaluating each company on the basis of its financial statements and operations. Factors such as management, financial condition, industry dynamics, earnings growth, profit margins, sales trends, dividend paying history and potential, as well as financial ratios and investment in research and development will be scrutinized as part of the advisor's analysis. The advisor seeks companies that are attractively valued and that have demonstrated or show the potential to demonstrate improved cash flow and return on invested capital. These may also include special situations companies that are experiencing management changes or are temporarily out of favor. This approach, combined with judgments about valuation and trends in the environment which tend to drive stock price appreciation, is intended to identify investment opportunities that the advisor believes will outperform the market and offer long-term financial reward.

The Fund also has an educational objective. It seeks to teach children and teenagers about mutual funds, basic economic principles and personal finance through a variety of educational materials. The materials are paid for by the Fund and distributed to shareholders on a regular basis.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.


2

THE FUND

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.


3

THE FUND

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for its Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Russell 3000 Index, an unmanaged index that tracks the performance of 3,000 of the largest U.S. companies, based on market capitalization. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on July 29, 2002, and Class Z shares were initially offered on April 29, 1994.

THE FUND

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

(1) The Fund pays a management fee of 0.58% and an administration fee of 0.18%.

(2) The Fund's advisor has voluntarily agreed to reimburse the Fund for certain expenses so that the transfer agency fees for each of Class A, B and C will not exceed 0.10%. If this reimbursement were reflected in the table, other expenses for each share class would be 0.28% and total annual fund operating expenses for Class A, B and C shares would be 1.34%, 2.04% and 2.04%, respectively (taking into account the 12b-1 fee waiver discussed in footnote (4) below). This arrangement may be modified or terminated by the advisor at any time.

(3) Other expenses have been restated to reflect contractual changes to the transfer agency fees and pricing and bookkeeping fees for the Fund effective November 1, 2005.

(4) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class A shares. If this waiver were reflected in the table the 12b-1 fee for Class A shares would be 0.30% and total annual fund operating expenses for Class A shares would be 1.34% (taking into account the reimbursement discussed in footnote (2) above). This arrangement may be modified or terminated by the distributor at any time.

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the tables below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.


11

YOUR ACCOUNT

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Automatic conversion to Class A shares occurs eight years after purchase.

CLASS C SHARES Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.


15

YOUR ACCOUNT

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Class A share distribution fee so that it does not exceed 0.05% annually. This arrangement may be modified or terminated by the distributor at any time. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating a portion of the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.

YOUR ACCOUNT


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
  transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

EDUCATIONAL MATERIALS

The Fund provides educational materials such as a newsletter and an activity book to all Fund shareholders. The materials are designed to teach children and teenagers basic investing principles. The Fund also sends investors an owner's manual. The educational materials and the owner's manual are paid for by the Fund.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.58% of average daily net assets of the Fund.

PORTFOLIO MANAGER

EMIL A. GJESTER, a vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2005. Mr. Gjester has been associated with Columbia Advisors or its predecessors since 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory,

MANAGING THE FUND

compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL.").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

CLASS Z SHARES

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC


Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.


On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

4. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

The Fund seeks long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in common stocks believed to have long-term growth potential. Under normal market conditions, the Fund invests at least 80% of its total assets in common stocks. The Fund may invest in companies of any size, ranging from small-cap companies to large-cap companies and the Fund's investments are diversified among industries and market sectors. The Fund seeks to invest in companies that produce products or provide services that the advisor believes children or teenagers use, are aware of, or have an interest in. Examples of these types of industries and market sectors include, but are not limited to, apparel and footwear, entertainment, retail, computer and electronics, Internet service providers, financial services and personal care products.

The Fund may invest up to 33% of its assets in foreign stocks including American Depositary Receipts. The Fund may also invest in securities convertible into or exercisable for stock (including preferred stock, warrants and debentures), certain options and financial futures contracts ("derivatives").

In selecting securities for the Fund, the Fund's investment advisor begins with a top-down industry sector analysis tracking specific sectors or industries of the market and identifying securities within those areas that are expected to reward shareholders. Through this process, the advisor determines the emphasis to be placed on different industries and selects individual stocks in which the Fund invests. In building the Fund's portfolio, the advisor combines this top-down approach with intensive bottom-up research of individual securities issues, evaluating each company on the basis of its financial statements and operations. Factors such as management, financial condition, industry dynamics, earnings growth, profit margins, sales trends, dividend paying history and potential, as well as financial ratios and investment in research and development will be scrutinized as part of the advisor's analysis. The advisor seeks companies that are attractively valued and that have demonstrated or show the potential to demonstrate improved cash flow and return on invested capital. These may also include special situations companies that are experiencing management changes or are temporarily out of favor. This approach, combined with judgments about valuation and trends in the environment which tend to drive stock price appreciation, is intended to identify investment opportunities that the advisor believes will outperform the market and offer long-term financial reward.

The Fund also has an educational objective. It seeks to teach children and teenagers about mutual funds, basic economic principles and personal finance through a variety of educational materials. The materials are paid for by the Fund and distributed to shareholders on a regular basis.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

THE FUND

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

THE FUND

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

Small- or mid-cap companies may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Russell 3000 Index, an unmanaged index that tracks the performance of 3,000 of the largest U.S. companies, based on market capitalization. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order.

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

YOUR ACCOUNT

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

YOUR ACCOUNT

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.


12

YOUR ACCOUNT

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

YOUR ACCOUNT

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current


14

YOUR ACCOUNT

market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

YOUR ACCOUNT

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

EDUCATIONAL MATERIALS

The Fund provides educational materials such as a newsletter and an activity book to all Fund shareholders. The materials are designed to teach children and teenagers basic investing principles. The Fund also sends investors an owner's manual. The educational materials and the owner's manual are paid for by the Fund.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.58% of average daily net assets of the Fund.

PORTFOLIO MANAGER

EMIL A. GJESTER, a vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2005. Mr. Gjester has been associated with Columbia Advisors or its predecessors since 1996.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.


17

MANAGING THE FUND

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006

COLUMBIA LIBERTY FUND
CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOALS

The Fund seeks primarily income and capital growth and, secondarily, capital preservation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund allocates its investments among various categories of equity and debt securities, including: large capitalization (large-cap) growth stocks, large-cap value stocks, foreign securities and investment grade bonds of U.S. issuers. Each asset class is managed by a separate portfolio manager or team with experience in investing in that particular class.

The Fund's lead portfolio manager will allocate the Fund's assets among the various asset classes. The lead portfolio manager will adjust the number of asset classes, as well as the portion of the Fund's assets allocated to each class, from time to time, based on his assessment of such factors as relative attractiveness, valuation, fundamentals, quantitative analyses and economic and market expectations.

In selecting equity securities, the Fund's investment advisor favors stocks with long-term growth potential that are expected to outperform their peers over time. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the Standard & Poor's 500 Index. As of December 31, 2005, that index included companies with capitalizations between approximately $778 million and $370.3 billion. All market capitalizations are determined at the time of purchase.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed-income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

The advisor also forecasts the direction and degree of change in long-term interest rates to help in the selection of debt securities. Investment grade debt securities purchased by the Fund will have one of the top four ratings assigned by Standard & Poor's Ratings Group or Moody's Investors Service, Inc., or will be unrated securities determined by the advisor to be of comparable quality. The Fund may also participate in mortgage dollar rolls.

At times, the advisor may maintain cash positions for liquidity purposes, temporary defensive purposes, or to implement the Fund's active allocation strategy.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities when not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative


3

THE FUND

positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns

THE FUND

include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Standard & Poor's 500 Index ("S&P Index"), an unmanaged index that tracks the performance of 500 widely held, large-capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index ("Lehman Index"), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

THE FUND

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower. Class A shares were initially offered on April 30, 1982, and Class C shares were initially offered on August 1, 1997.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

This arrangement results in a rate of service fee for all shares that is a blend between the 0.15% and 0.25% rates.

(2) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

YOUR ACCOUNT

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

YOUR ACCOUNT

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS C SHARES Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange

privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


15

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

12b-1 PLAN The Fund has adopted a plan under Rule 12b-l that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee is calculated by adding (1) 0.15% on net assets attributable to shares issued prior to April 1, 1989 and (2) 0.25% on net assets attributable to shares issued thereafter. This arrangement results in a rate of service fee payable by the Fund that is a blend between the 0.15% and 0.25% rates. For the fiscal year ended September 30, 2005, the combined service fee was 0.23% of the Fund's average net assets. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.


16

YOUR ACCOUNT

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However,


17

YOUR ACCOUNT

where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late


23

MANAGING THE FUND

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS
When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms. In a dollar roll, the Fund sells a security and simultaneously enters into a commitment to purchase a similar security at a later date. Dollar rolls also involve the risk that the other party may not honor the contract terms.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED FEBRUARY 1, 2006

COLUMBIA LIBERTY FUND
CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.


A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOALS

The Fund seeks primarily income and capital growth and, secondarily, capital preservation.

PRINCIPAL INVESTMENT STRATEGIES

The Fund allocates its investments among various categories of equity and debt securities, including: large capitalization (large-cap) growth stocks, large-cap value stocks, foreign securities and investment grade bonds of U.S. issuers. Each asset class is managed by a separate portfolio manager or team with experience in investing in that particular class.

The Fund's lead portfolio manager will allocate the Fund's assets among the various asset classes. The lead portfolio manager will adjust the number of asset classes, as well as the portion of the Fund's assets allocated to each class, from time to time, based on his assessment of such factors as relative attractiveness, valuation, fundamentals, quantitative analyses and economic and market expectations.

In selecting equity securities, the Fund's investment advisor favors stocks with long-term growth potential that are expected to outperform their peers over time. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the Standard & Poor's 500 Index. As of December 31, 2005, that index included companies with capitalizations between approximately $778 million and $370.3 billion. All market capitalizations are determined at the time of purchase.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed-income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

The advisor also forecasts the direction and degree of change in long-term interest rates to help in the selection of debt securities. Investment grade debt securities purchased by the Fund will have one of the top four ratings assigned by Standard & Poor's Ratings Group or Moody's Investors Service, Inc., or will be unrated securities determined by the advisor to be of comparable quality. The Fund may also participate in mortgage dollar rolls.

At times, the advisor may maintain cash positions for liquidity purposes, temporary defensive purposes, or to implement the Fund's active allocation strategy.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities when not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative

THE FUND

positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Growth stocks are stocks of companies believed to have above-average potential for growth in revenue and earnings. Prices of growth stocks may be more sensitive to changes in current or expected earnings than the prices of other stocks. Growth stocks may not perform as well as value stocks or the stock market in general.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance

THE FUND

results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Standard & Poor's 500 Index ("S&P Index"), an unmanaged index that tracks the performance of 500 widely held, large-capitalization U.S. stocks. The Fund's returns are also compared to the Lehman Brothers Aggregate Bond Index ("Lehman Index"), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds


9

YOUR ACCOUNT

Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

YOUR ACCOUNT

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals or other entertainment; and/or (iii) support for financial service firm educational or training events.


13

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities

-----------------------------------------------------------------------------------

                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.


15

YOUR ACCOUNT

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late


20

MANAGING THE FUND

trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of the litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and entered final judgement. The plaintiffs filed a notice of appeal on December 30, 2005.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS
When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms. In a dollar roll, the Fund sells a security and simultaneously enters into a commitment to purchase a similar security at a later date. Dollar rolls also involve the risk that the other party may not honor the contract terms.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last six fiscal periods, which run from October 1 to September 30, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the fiscal years ended September 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the period ended September 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

The Funds' Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Funds

INVESTMENT GOAL

Each Fund seeks as high a level of current interest income exempt from federal income tax and, to the extent possible, from the personal income tax of its state, as is consistent with relative stability of principal.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund normally invests at least 80% of its net assets plus any borrowings for investment purposes in the municipal securities of its state, which are securities issued by that state and other governmental issuers (potentially including issuers located outside that state) and that pay interest which is exempt from both federal income tax (including the federal alternative minimum tax) and the income tax of that state and, in the case of the Connecticut Intermediate Municipal Bond Fund and the Massachusetts Intermediate Municipal Bond Fund, mutual funds that invest in that state's municipal securities. Under normal circumstances, each Fund will invest no more than 20% of its net assets in taxable obligations, such as U.S. Government obligations, money market instruments and repurchase agreements.

Municipal securities purchased by each Fund may include general obligation securities, revenue securities and private activity bonds. The interest on private activity bonds may be subject to the federal alternative minimum tax. Investments in private activity bonds will not be treated as investments in municipal securities for purposes of the 80% requirement stated above. Each Fund is "non-diversified," which means that it is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund.

Each Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Funds may use derivatives for both hedging and non-hedging purposes, such as to adjust a Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Funds typically use derivatives in an effort to achieve more efficiently economic exposures similar to those they could have achieved through the purchase and sale of municipal securities.

In selecting portfolio securities for a Fund, each Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. Each Fund's advisor also determines the appropriate allocation of its Fund's assets among various issuers and industry sectors.

Nearly all of the investments of a Fund will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the Fund's advisor to be of comparable quality. Under normal market conditions, each Fund will invest at least 65% of its total assets in securities that have one of the top three ratings assigned by S&P or Moody's or unrated securities determined by its advisor to be of comparable quality. Occasionally, the rating of a security held by a Fund may be downgraded to below investment grade. If that happens, a Fund does not have to sell the security, unless its advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, each Fund will sell promptly any rated securities that are not rated investment grade by either S&P or Moody's if the securities exceed 5% of the Fund's net assets.

Under normal circumstances, each Fund's average weighted maturity is expected to be between three and ten years.

Each Fund will sell a security when, as a result of changes in the economy or the performance of the security or other circumstances, its advisor believes that holding the security is no longer consistent with the Fund's investment goal.


2

The Funds

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily a Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

In seeking to achieve its investment goal, each Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in each Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent a Fund from achieving its investment goal. You may lose money by investing in the Funds.

As a non-diversified mutual fund, each Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. Each Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

Management risk means that the advisor's investment decisions might produce losses or cause a Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal securities holders. Because of management and market risk, there is no guarantee that a Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income a Fund receives from them but will affect the value of a Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in special revenue obligations, including asset-backed securities and debt securities issued by private entities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payments of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.


3

The Funds

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing a Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause a Fund to receive taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from a Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for a Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Funds may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The interest income distributed by a Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

Municipal Market Risk and Single-State Focus: A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in the state will be affected by these factors, which will, in turn, affect the value of the Fund's investments. Because the Fund invests primarily in municipal securities of a particular state, the value of the Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY (CONNECTICUT)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Retail A Shares (the predecessor to the Fund's Class T shares) of the Galaxy Connecticut Intermediate Municipal Bond Fund (the Galaxy Connecticut Fund), the predecessor to the Fund, for periods prior to November 18, 2002, the date on which Class A shares were initially offered by the Fund, returns of Trust Shares of the Galaxy Connecticut Fund for periods prior to June 26, 2001, and returns of shares of the Boston 1784 Connecticut Tax-Exempt Income Fund (the 1784 Connecticut Fund), the predecessor to the Galaxy Connecticut Fund, for periods prior to June 26, 2000. Class A, B and C shares would have substantially similar returns because they are invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A, B and C shares exceed expenses paid by Class T shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

---------------------------------------------------------------------------------------------------------------------------

UNDERSTANDING EXPENSES
Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and
other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal
fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that
make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The
Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses
disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities
for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as
potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of
transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the
Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The
table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund
Operating Expenses table. It uses the following hypothetical conditions:
.  $10,000 initial investment
.  5% total return for each year
.  Fund operating expenses remain the same
.  Reinvestment of all dividends and distributions
.  Class B shares convert to Class A shares after eight years

This arrangement may be modified or terminated by the distributor at any time.

PERFORMANCE HISTORY (MASSACHUSETTS)

The bar chart below shows the Fund's calendar year total returns before taxes for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance, over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Retail A Shares (the predecessor to the Fund's Class T shares) of the Galaxy Massachusetts Intermediate Municipal Bond Fund (the Galaxy Massachusetts Fund), the predecessor to the Fund, for periods prior to December 9, 2002, the date on which Class A shares were initially offered by the Fund, returns of Trust Shares of the Galaxy Massachusetts Fund for periods prior to June 26, 2001, and returns of shares of the Boston 1784 Massachusetts Tax-Exempt Income Fund (the 1784 Massachusetts Fund), the predecessor to the Galaxy Massachusetts Fund, for periods prior to June 26, 2000. Class A, B and C shares would have substantially similar returns because they are invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A, B and C shares exceed expenses paid by Class T shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table, the 12b-1 fee for Class C shares would be 0.65% and total annual fund operating expenses for Class C shares would be 1.48%. This arrangement may be modified or terminated by the distributor at any time.
(3) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

PERFORMANCE HISTORY (NEW YORK)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance, over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Retail A Shares (the predecessor to the Fund's Class T shares) of the Galaxy New York Municipal Bond Fund (the Galaxy New York Fund), the predecessor to the Fund, for periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. Class A, B and C shares would have substantially similar returns because they are invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A, B and C shares exceed expenses paid by Class T shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When a Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Funds' transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of a Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

------------------------------------------------------------

CHOOSING A SHARE CLASS
Each Fund offers three classes of shares in this prospectus
-- Class A, B and C. Each share class has its own sales
charge and expense structure. Determining which share class
is best for you depends on the dollar amount you are
investing and the number of years for which you are willing
to invest. Purchases of $50,000 or more but less than $1
million can be made only in Class A or Class C shares.
Purchases of $1 million or more can be made only in Class A
shares. Based on your personal situation, your financial
advisor can help you decide which class of shares makes the
most sense for you.

The Funds also offer additional classes of shares,
including Class T, G and Z shares, exclusively to certain
institutional and other investors. Class T, G and Class Z
shares are made available through separate prospectuses
provided to eligible institutional and other investors.


26

Your Account

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00

$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Funds and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Funds will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, a Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include


28

Your Account

those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Funds are not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by a Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Funds' transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Funds' Statement of Additional Information which can be obtained at www.columbiafunds.com or by calling 1-800-345-6611.

Class B shares Your purchases of Class B shares are made at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Funds may not be able to do anything in response to market timing that occurs in the Funds which may result in certain shareholders being able to market time the Funds while the shareholders in the Funds bear the burden of such activities.


32

Your Account

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers") have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Funds following various suspension periods.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan Each Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of each Fund's Class C share distribution fee so that it does not exceed 0.40% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by the financial service firm to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of a Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Funds' Share Price is Determined The price of each class of a Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

Each Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

The Funds have retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Funds. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Funds have the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by a Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


34

Your Account

Distribution Options The Funds declare any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, a Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences For federal income tax purposes, distributions of investment income by a Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by a Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in a Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Funds intend to distribute federally tax-exempt income. The Funds may invest a portion of their assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Funds

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Funds' investment advisor. Columbia Advisors is responsible for the Funds' management, subject to oversight by the Funds' Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Funds, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by each of the Funds, amounted to 0.48% of average daily net assets of each Fund. A discussion of the factors considered by the Funds' Board of Trustees in approving the Funds' investment advisory contracts is included in the Funds' annual report to shareholders for the fiscal year ended October 31, 2005.

PORTFOLIO MANAGERS

Susan Sanderson, a vice president of Columbia Advisors, is the manager for the Massachusetts Fund and has managed the Fund since it commenced operations in 1993. Ms. Sanderson has been associated with Columbia Advisors or its predecessors since 1985.

Brian McGreevy, a vice president of Columbia Advisors, is the manager for the New Jersey, Rhode Island, Connecticut and New York Funds, and has managed the New Jersey Fund since January, 1998, the Rhode Island Fund since July, 1997, the Connecticut Fund since September, 2002, and the New York Fund since July, 1997. Mr. McGreevy has been associated with Columbia Advisors or its predecessors since December, 1994.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Funds.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


36

Managing the Funds

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On November 3, 2005, the U.S. District Court for the District of Maryland dismissed the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims against Columbia and others. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and
Section 36(b) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from


37

Managing the Funds

contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

For the year ended November 30, 2005, Columbia has assumed $35,472 of legal, consulting services and Trustees' fees incurred by the fund in connection with these matters.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of each Fund, including investment advisory fees and other Fund costs, on each Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of each Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for each Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in


consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Funds

INVESTMENT GOAL

Each Fund seeks as high a level of current interest income exempt from federal income tax and, to the extent possible, from the personal income tax of its state, as is consistent with relative stability of principal.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund normally invests at least 80% of its net assets plus any borrowings for investment purposes in the municipal securities of its state, which are securities issued by that state and other governmental issuers (potentially including issuers located outside that state) and that pay interest which is exempt from both federal income tax (including the federal alternative minimum tax) and the income tax of that state and, in the case of the Connecticut Intermediate Municipal Bond Fund and the Massachusetts Intermediate Municipal Bond Fund, mutual funds that invest in that state's municipal securities. Under normal circumstances, each Fund will invest no more than 20% of its net assets in taxable obligations, such as U.S. Government obligations, money market instruments and repurchase agreements.

Municipal securities purchased by each Fund may include general obligation securities, revenue securities and private activity bonds. The interest on private activity bonds may be subject to the federal alternative minimum tax. Investments in private activity bonds will not be treated as investments in municipal securities for purposes of the 80% requirement stated above. Each Fund is "non-diversified," which means that it is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund.

Each Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Funds may use derivatives for both hedging and non-hedging purposes, such as to adjust a Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Funds typically use derivatives in an effort to achieve more efficiently economic exposures similar to those they could have achieved through the purchase and sale of municipal securities.

In selecting portfolio securities for a Fund, each Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. Each Fund's advisor also determines the appropriate allocation of its Fund's assets among various issuers and industry sectors.

Nearly all of the investments of a Fund will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the Fund's advisor to be of comparable quality. Under normal market conditions, each Fund will invest at least 65% of its total assets in securities that have one of the top three ratings assigned by S&P or Moody's or unrated securities determined by its advisor to be of comparable quality. Occasionally, the rating of a security held by a Fund may be downgraded to below investment grade. If that happens, a Fund does not have to sell the security, unless its advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, each Fund will sell promptly any securities that are not rated investment grade by either S&P or Moody's if the securities exceed 5% of the Fund's net assets.

Under normal circumstances, each Fund's average weighted maturity is expected to be between three and ten years.

Each Fund will sell a security when, as a result of changes in the economy or the performance of the security or other circumstances, its advisor believes that holding the security is no longer consistent with the Fund's investment goal.


2

The Funds

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily a Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

In seeking to achieve its investment goal, each Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in each Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent a Fund from achieving its investment goal. You may lose money by investing in the Funds.

As a non-diversified mutual fund, each Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. Each Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

Management risk means that the advisor's investment decisions might produce losses or cause a Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal securities holders. Because of management and market risk, there is no guarantee that a Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income a Fund receives from them but will affect the value of a Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in special revenue obligations, including asset-backed securities and debt securities issued by private entities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payments of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.


3

The Funds

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing a Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause a Fund to receive taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from a Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for a Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Funds may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The interest income distributed by a Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

Municipal Market Risk and Single-State Focus. A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in the state will be affected by these factors, which will, in turn, affect the value of the Fund's investments. Because the Fund invests primarily in municipal securities of a particular state, the value of the Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY (CONNECTICUT)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

Retail A share returns include returns for BKB Shares of the Galaxy Connecticut Fund for periods prior to June 26, 2001, the date on which BKB Shares were converted into Retail A Shares. The returns shown for Class T shares also include the returns of Trust Shares of the Galaxy Connecticut Fund for periods prior to the inception of Retail A Shares (June 26, 2000). Class T shares generally would have had substantially similar returns to Trust shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class T shares exceed expenses paid by Trust Shares.

The Funds

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

The returns shown for Class T shares and Class G shares also include the returns of Trust Shares of the Galaxy Connecticut Fund (adjusted, as necessary, to reflect the sales charges applicable to Class T shares and Class G shares) for periods prior to the date of inception of Retail A Shares (June 26, 2000). Trust shares of the Galaxy Connecticut Fund were initially offered on August 1, 1994. Class T and Class G shares generally would have had substantially similar returns to Trust Shares because they would have been invested in the same portfolio of securities, although returns would be lower to the extent that expenses for Class T and Class G shares exceed expenses paid by Trust Shares. Class T and G shares were initially offered on November 18, 2002.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

PERFORMANCE HISTORY (MASSACHUSETTS)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges./ /

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

Retail A share returns include returns for BKB Shares of the Galaxy Massachusetts Fund for periods prior to June 26, 2001, the date on which BKB Shares were converted into Retail A Shares. The returns shown for Class T shares also include the returns of Trust Shares of the Galaxy Massachusetts Fund for periods prior to the inception of Retail A Shares (June 26, 2000). Class T shares generally would have had substantially similar returns as Trust shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class T shares exceed expenses paid by Trust Shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

PERFORMANCE HISTORY (NEW JERSEY)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and for the life of the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each complete calendar year since the Fund commenced operations. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and life of the Fund periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding.

The performance table following the bar chart shows how the Fund's average annual total returns for Class T and Class G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares) for periods prior to the inception of Retail B Shares of the Galaxy New York Fund (March 1, 2001). Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares. Retail A Shares were initially offered on December 31, 1991.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. Except as noted, the table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class G shares convert to Class T shares after eight years

PERFORMANCE HISTORY (RHODE ISLAND)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Except as noted, any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When a Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Funds' transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of a Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

Class T shares Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares.

Class T shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class T share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class T share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC for Class G shares, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Funds and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Funds will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, a Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts
. Joint accounts
. Certain IRA accounts
. Certain trusts
. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be

Your Account

aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Funds are not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by a Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Funds' transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Funds' Statement of Additional Information which can be obtained at www.columbiafunds.com or by calling 1-800-345-6611.

Class G shares Your purchases of Class G shares are made at Class G's net asset value. Purchases up to $50,000 are allowed in Class G shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class G shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Commission to financial advisors is 4.00%.

Class G shares will automatically convert to Class T shares eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and you may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-338-2550. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


31

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Funds may not be able to do anything in response to market timing that occurs in the Funds which may result in certain shareholders being able to market time the Funds while the shareholders in the Funds bear the burden of such activities.

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers") have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Funds following various suspension periods.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Each Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. Each Fund does not intend to pay more than a total of 0.80% for Class G shares in distribution and shareholder service fees during the current fiscal

Your Account

year. Each Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Rhode Island Fund does not intend to pay shareholder service fees for its Class T shares during the current fiscal year, and each Fund (other than the Rhode Island Fund) does not intend to pay more than 0.15% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by the financial service firm to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of a Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Funds' Share Price is Determined The price of each class of a Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


33

Your Account

Each Fund determines its net asset value for its share classes by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

The Funds have retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value) your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Funds.

Dividends, Distributions and Taxes The Funds have the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by a Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Funds declare any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.


34

Your Account

If you do not indicate on your application or at the time your account is established your preference for handling distributions, a Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences For federal income tax purposes, distributions of investment income by a Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by a Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in a Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Funds intend to distribute federally tax-exempt income. The Funds may invest a portion of their assets in securities that generate income subject to federal or state income taxes.

Managing the Funds

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Funds' investment advisor. Columbia Advisors is responsible for the Funds' management, subject to oversight by the Funds' Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Funds, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by each of the Funds, amounted to 0.48%, of average daily net assets of each Fund. A discussion of the factors considered by the Funds' Board of Trustees in approving the Funds' investment advisory contract is included in the Funds' annual report to shareholders for the fiscal year ended October 31, 2005.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


36

Managing the Funds

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On November 3, 2005, the U.S. District Court for the District of Maryland dismissed the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims against Columbia and others. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and
Section 36(b) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.


37

Managing the Funds

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

For the year ended November 30, 2005, Columbia has assumed $35,472 of legal, consulting services and Trustees' fees incurred by the fund in connection with these matters.

Financial Highlights

The financial highlights table is intended to help you understand each Fund's financial performance. Information is shown for each Fund's last five fiscal years or since inception, which run from November 1 to October 31, unless otherwise indicated. Information for Class T shares and Class G shares prior to the date of reorganization, as further described in the footnotes to each Fund's financial highlights, is for the former Retail A shares and Retail B shares, of the respective Galaxy Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions). This information has been derived from each Fund's financial statements which, for the years ended October 31, 2005 and October 31, 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Funds' financial statements, is included in the Funds' annual report. The information for the years and periods ended October 31, 2003, 2002 and 2001 has been derived from the Funds' financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of each Fund, including investment advisory fees and other Fund costs, on each Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class T and G shares of each Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratios used for each Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in


consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Funds

INVESTMENT GOAL

Each Fund seeks as high a level of current interest income exempt from federal income tax and, to the extent possible, from the personal income tax of its state, as is consistent with relative stability of principal.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund normally invests at least 80% of its net assets plus any borrowings for investment purposes in the municipal securities of its state, which are securities issued by that state and other governmental issuers (potentially including issuers located outside that state) and that pay interest which is exempt from both federal income tax (including the federal alternative minimum tax) and the income tax of that state and, in the case of the Connecticut Intermediate Municipal Bond Fund and the Massachusetts Intermediate Municipal Bond Fund, mutual funds that invest in that state's municipal securities. Under normal circumstances, each Fund will invest no more than 20% of its net assets in taxable obligations, such as U.S. Government obligations, money market instruments and repurchase agreements.

Municipal securities purchased by each Fund may include general obligation securities, revenue securities and private activity bonds. The interest on private activity bonds may be subject to the federal alternative minimum tax. Investments in private activity bonds will not be treated as investments in municipal securities for purposes of the 80% requirement stated above. Each Fund is "non-diversified," which means that it is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund.

Each Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Funds may use derivatives for both hedging and non-hedging purposes, such as to adjust a Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Funds typically use derivatives in an effort to achieve more efficiently economic exposures similar to those they could have achieved through the purchase and sale of municipal securities.

In selecting portfolio securities for a Fund, each Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. Each Fund's advisor also determines the appropriate allocation of its Fund's assets among various issuers and industry sectors.

Nearly all of the investments of a Fund will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the Fund's advisor to be of comparable quality. Under normal market conditions, each Fund will invest at least 65% of its total assets in securities that have one of the top three ratings assigned by S&P or Moody's or unrated securities determined by its advisor to be of comparable quality. Occasionally, the rating of a security held by a Fund may be downgraded to below investment grade. If that happens, a Fund does not have to sell the security, unless its advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, each Fund will sell promptly any securities that are not rated investment grade by either S&P or Moody's if the securities exceed 5% of the Fund's net assets.

Under normal circumstances, each Fund's average weighted maturity is expected to be between three and ten years.

Each Fund will sell a security when, as a result of changes in the economy or the performance of the security or other circumstances, its advisor believes that holding the security is no longer consistent with the Fund's investment goal.


2

The Funds

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily a Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

In seeking to achieve its investment goal, each Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in each Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent a Fund from achieving its investment goal. You may lose money by investing in the Funds.

As a non-diversified mutual fund, each Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. Each Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

Management risk means that the advisor's investment decisions might produce losses or cause a Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal securities holders. Because of management and market risk, there is no guarantee that a Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income a Fund receives from them but will affect the value of a Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in special revenue obligations, including asset-backed securities and debt securities issued by private entities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payments of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.


3

The Funds

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing a Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause a Fund to receive taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from a Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for a Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Funds may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The interest income distributed by a Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

Municipal Market Risk and Single-State Focus: A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in the state will be affected by these factors, which will, in turn, affect the value of the Fund's investments. Because the Fund invests primarily in municipal securities of a particular state, the value of the Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY (CONNECTICUT)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

PERFORMANCE HISTORY (MASSACHUSETTS)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Brothers 3-15 Year Bond Index), an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990 with remaining maturities between 2 and 17 years and at least $5 million in principal amount outstanding. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

(1) The average annual total returns shown include returns of Trust Shares of the Galaxy Rhode Island Fund for periods prior to November 18, 2002, the date on which Class Z shares were initially offered by the Fund. The returns for Class Z shares also include the returns of Retail A Shares of the Galaxy Rhode Island Fund for periods prior to the inception of Trust Shares (June 19, 2000). Class Z shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been higher to the extent that expenses for Class Z shares are lower than expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Funds, directly or by exchange. Class Z shares of the Funds generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by a Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.


21

Your Account

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary; or

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Funds' transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement).

The Funds reserve the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Funds also reserve the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Funds offer one class of shares in this prospectus -- Class Z.

The Funds also offer five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, a Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Funds may not be able to do anything in response to market timing that occurs in the Funds which may result in certain shareholders being able to market time the Funds while the shareholders in the Funds bear the burden of such activities.


24

Your Account

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers") have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Funds following various suspension periods.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of a Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Funds' Share Price is Determined The price of a Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.


25

Your Account

Each Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

The Funds have retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Funds have the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by a Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options Each Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, a Fund will automatically reinvest all distributions in additional shares of the Fund.

Your Account

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences For federal income tax purposes, distributions of investment income by a Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by a Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in a Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Funds intend to distribute federally tax-exempt income. The Funds may invest a portion of their assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Funds' investment advisor. Columbia Advisors is responsible for the Funds' management, subject to oversight by the Funds' Board of Trustees. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Funds, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by each of the Funds amounted to 0.48% of average daily net assets of each Fund. A discussion of the factors considered by the Funds' Board of Trustees in approving the Funds' investment advisory contract is included in the Funds' annual report to shareholders for the fiscal year ended October 31, 2005.

PORTFOLIO MANAGERS

Susan Sanderson, a vice president of Columbia Advisors, is the manager for the Massachusetts Fund and has managed the Fund since it commenced operations in 1993. Ms. Sanderson has been associated with Columbia Advisors or its predecessors since 1985.

Brian McGreevy, a vice president of Columbia Advisors, is the manager for the New Jersey, Rhode Island, Connecticut and New York Funds, and has managed the New Jersey Fund since January, 1998, the Rhode Island Fund since July, 1997, the Connecticut Fund since September, 2002, and the New York Fund since July, 1997. Mr. McGreevy has been associated with Columbia Advisors or its predecessors since December, 1994.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Funds.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


28

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On November 3, 2005, the U.S. District Court for the District of Maryland dismissed the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims against Columbia and others. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and
Section 36(b) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemptin from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.


29

Managing the Fund

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

For the year ended November 30, 2005, Columbia has assumed $35,472 of legal, consulting services and Trustees' fees incurred by the fund in connection with these matters.

Financial Highlights

The financial highlights table is intended to help you understand each Fund's Class Z financial performance. Information is shown for the last five fiscal years, which run from November 1 to October 31, unless otherwise indicated. Certain information shown for each Fund is that of Trust Shares of its predecessor Galaxy Fund, as further described in the footnotes to each Fund's financial highlights tables. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions). This information has been derived from each Fund's financial statements, which, for the years ended October 31, 2005 and October 31, 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Funds' financial statements, is included in the Funds' annual report. The information for the years ended October 31, 2003, 2002 and 2001 has been derived from the Funds' financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

APPENDIX A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of each Fund, including investment advisory fees and other Fund costs, on each Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of each Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested. The annual expense ratio used for each Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent


distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were


consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Funds

INVESTMENT GOAL

Each Fund seeks as high a level of after-tax total return as is consistent with prudent risk.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund seeks to achieve its investment goal by pursuing current income exempt from federal income tax and its state's personal income tax (if any) and by pursuing opportunities for long-term appreciation. Under normal market conditions, each Fund invests at least 80% of its total assets in municipal bonds, the interest on which is exempt from federal income tax and that state's personal income tax. Bonds subject to the alternative minimum tax will not be counted for purposes of the 80% test described above. In selecting municipal bonds for a Fund, the Fund's investment advisor primarily invests in "investment grade" securities, which are securities rated in the four highest categories by Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), Moody's Investors Service, Inc. ("Moody's"), or other nationally recognized rating agencies, and in unrated securities that the advisor believes to be comparable in quality to investment grade securities.

Each Fund may also invest up to 25% of its total assets in lower-rated debt securities, which are rated below investment grade by Moody's, S&P or other nationally recognized rating agencies, or comparable unrated securities. Each Fund is "non-diversified," which means that it is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund.

The Funds may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Funds may use derivatives for both hedging and non-hedging purposes, such as to adjust the Funds' sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Funds typically use derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of municipal securities.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."


UNDERSTANDING TAX-EXEMPT BONDS

Tax-exempt bonds are issued by state and local governments for various public purposes. The interest on tax-exempt bonds, typically, is not subject to federal and state income tax. As a result, the yields on tax-exempt securities are generally lower than the yields on taxable bonds with similar maturities. However, a portion or all of such interest may be subject to a shareholder's federal alternative minimum tax liability. Tax-exempt bond funds may be appropriate for investors in high tax brackets who seek current income that is free from state and federal tax.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Funds from achieving their investment goal. You may lose money by investing in the Funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values

The Funds

of bonds usually will not affect the amount of income the Funds receive from them but will affect the value of the Funds' shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Reinvestment risk is the risk that income from each Fund's debt securities will decline if and when each Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of each Fund's portfolio.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. These bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

Municipal Market Risk and Single-State Focus: A state's municipal market may be volatile and can be significantly affected by adverse tax, legislative, demographic or political changes, as well as changes in the financial or economic condition of the state that issues municipal securities. Municipal issues in each state will be affected by these factors, which will, in turn, affect the value of each Fund's investments. Because each of the Funds invests primarily in municipal securities of a particular state, the value of each Fund's shares may be more volatile than the value of shares of funds that invest in securities of issuers in a number of different states.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Funds to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also cause the Funds to receive

The Funds

taxable income, which could increase the amount of taxes payable by shareholders. Other risks arise from the Funds' potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Funds' derivative positions at times when the Funds might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Funds may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

The interest income distributed by the Funds from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, each Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

As a non-diversified mutual fund, each Fund is allowed to invest a greater percentage of its total assets in the securities of fewer issuers than a "diversified" fund. Each Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. All information in this prospectus relating to the Fund for periods prior to September 19, 2005, including the performance information shown below, is that of Columbia California Tax-Exempt Fund, a series of Columbia Funds Trust V, the predecessor to the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Municipal Bond Index ("Lehman Index"), an unmanaged index that tracks the performance of the municipal bond market. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper California Municipal Debt Funds Category ("Lipper Average"), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class B shares for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class B shares and the newer class of shares. Class A shares were initially offered on June 16, 1986, Class B shares were initially offered on August 4, 1992, and Class C shares were initially offered on August 1, 1997.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) The Fund's Advisor has contractually agreed to bear a portion of the Fund's expenses so that the Fund's ordinary operating expenses (excluding any distribution and service fees, tax and interest expenses) do not exceed 0.60% until September 16, 2006. If the waiver were reflected in the table, total annual fund operating expenses would be 0.82% for Class A, 1.57% for Class B and 1.27% for Class C, (taking into account the 12b-1 fee waiver discussed in footnote (3) below). After September 16, 2006, this arrangement may be modified or terminated by the Advisor at any time.
(2) The annual service fee portion of the 12b-1 fee may equal up to 0.10% on net assets attributable to shares issued prior to December 1, 1994 and 0.25% on net assets attributable to shares issued thereafter. This arrangement results in a rate of service fee for all shares that is a blend between the 0.10% and 0.25% rates.
(3) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table, the 12b-1 fee for Class C shares would be 0.67%, and total annual fund operating expenses for Class C shares would be 1.27% (taking into account the fee waiver discussed in footnote 1 above). This arrangement may be modified or terminated by the distributor at any time.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

. $ 10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) The Fund's advisor has voluntarily agreed to waive advisory fees and reimburse the Fund for certain expenses so that the total annual fund operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) will not exceed 0.60%. If this waiver were reflected in the table, the management fee for each share class would be 0.41% and total annual fund operating expenses for Class A, B and C shares would be 0.84%, 1.59% and 1.29%, respectively (taking into account the 12b-1 fee waiver discussed in footnote 3 below). This arrangement may be modified or terminated by the advisor at any time.
(2) The annual service fee portion of the 12b-1 fee may equal up to 0.10% on net assets attributable to shares issued prior to December 1, 1994 and 0.25% on net assets attributable to shares issued thereafter. This arrangement results in a rate of service fee for all shares that is a blend between the 0.10% and 0.25% rates.
(3) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table, the 12b-1 fee for Class C shares would be 0.68%, and total annual fund operating expenses for Class C shares would be 1.29% (taking into account the fee waiver discussed in footnote 1 above). This arrangement may be modified or terminated by the distributor at any time.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

Columbia Massachusetts Tax-Exempt Fund

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Municipal Bond Index ("Lehman Index"), an unmanaged index that tracks the performance of the municipal bond market. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper Massachusetts Municipal Debt Funds Category ("Lipper Average"), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) The Fund's advisor has voluntarily agreed to waive advisory fees and reimburse the Fund for certain expenses so that the total annual fund operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) will not exceed 0.60%. If this waiver were reflected in the table, the management fee for each share class would be 0.35% and total annual fund operating expenses for Class A, B and C shares would be 0.84%, 1.59% and 1.29%, respectively (taking into account the 12b-1 fee waiver discussed in footnote 3 below). This arrangement may be modified or terminated by the advisor at any time.
(2) The annual service fee portion of the 12b-1 fee may equal up to 0.10% on net assets attributable to shares issued prior to December 1, 1994 and 0.25% on net assets attributable to shares issued thereafter. This arrangement results in a rate of service fee for all shares that is a blend between the 0.10% and 0.25% rates.
(3) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table, the 12b-1 fee for Class C shares would be 0.69%, and total annual fund operating expenses for Class C shares would be 1.29% (taking into account the fee waiver discussed in footnote 1 above). This arrangement may be modified or terminated by the distributor at any time.
(4) Other expenses have been restated to reflect contractual changes to the fees paid by the Fund for transfer agency and pricing and bookkeeping services effective November 1, 2005.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When a Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Funds' transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of a Fund. These sales charges are described below. In certain circumstances, the sales charges may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Funds offer three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

Columbia California Tax-Exempt Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the


22

Your Account

first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Funds and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.


23

Your Account

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information which can be obtained at www.columbiafunds.com or by calling 1-800-345-6611.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share Class (and, in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Shareholders of Columbia Acorn funds that qualify to purchase Class A shares at net asset value may exchange their Class A shares for Class Z shares of another fund distributed by Columbia Management Distributors, Inc. (see the Statement of Additional Information for a description of these situations). Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize


25

Your Account

a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if a Fund determines that any person, group or account has


27

Your Account

engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Funds may not be able to do anything in response to market timing that occurs in a Fund which may result in certain shareholders being able to market time a Fund while the shareholders in that Fund bear the burden of such activities. Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers")) have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Funds' practices discussed above. In particular, the Bank of America retirement service provider permits the reinstatement of future purchase orders for shares of Columbia Funds following various suspension periods.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan Each Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee is calculated by adding
(1) 0.10% on net assets attributable to shares issued prior to December 1, 1994 and (2) 0.25% on net assets attributable to shares issued thereafter. This arrangement results in a rate of service fee payable by the Funds that is a blend between the 0.10% and 0.25% rates. For the fiscal year ended October 31, 2005, each Fund's combined service fee was the following percentage of each Fund's average net assets: California Tax-Exempt Fund 0.22%; Connecticut Tax-Exempt Fund 0.24%; Massachusetts Tax-Exempt Fund 0.22% and New York Tax-Exempt Fund 0.24%. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of each Fund's Class C share distribution fee so that it does not exceed 0.45% annually. This arrangement may be modified or terminated by the distributor at any time. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Funds on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How a Fund's Share Price is Determined The price of each class of a Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on


29

Your Account

each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

Each Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

The Funds have retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Funds' transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Funds. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions, and Taxes The Funds have the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Funds, net of expenses incurred by the Funds.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less


UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of a Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


30

Your Account

Distribution Options The Funds declare any dividends daily and pay them monthly, and declare and pay any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, a Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences For federal income tax purposes, distributions of investment income by a Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by a Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in a Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Funds intend to distribute federally tax-exempt income. The Funds may invest a portion of their assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Funds

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Funds' investment advisor. Columbia Advisors is responsible for Funds' management, subject to oversight by the Funds' Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Funds' day-to-day business, including placing all orders for the purchase and sale of the Funds' portfolio securities.

Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management and/or Columbia Advisors by Columbia California Tax-Exempt Fund, Columbia Connecticut Tax-Exempt Fund, Columbia Massachusetts Tax-Exempt Fund and Columbia New York Tax-Exempt Fund not including pricing and bookkeeping and other fees paid to Columbia Management and/or Columbia Advisors by the Funds, amounted to 0.50%, 0.50%, 0.50% and 0.50% of average daily net assets of the Funds, respectively. A discussion of the factors considered by the Funds' Boards of Trustees in approving the Funds' investment advisory contracts is included in the Funds' annual reports to shareholders for the period ended October 31, 2005.

PORTFOLIO MANAGER

Gary Swayze, a senior vice president of Columbia Advisors, is the manager for each Fund and has managed the New York Fund since September, 1997, the California Fund since October, 1997, the Connecticut Fund since November, 1997 and the Massachusetts Fund since July, 1998. Mr. Swayze has been associated with Columbia Advisors or its predecessor since 1997.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Funds.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


32

Managing the Funds

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On November 3, 2005, the U.S. District Court for the District of Maryland dismissed the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims against Columbia and others. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and
Section 36(b) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.


33

Managing the Funds

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

Other Investment Strategies and Risks

Each Fund's principal investment strategies and their associated risks are described under "The Funds --Principal Investment Strategies" and "The Funds -- Principal Investment Risks." This section describes other investments the Funds may make and the risks associated with them. In seeking to achieve their investment goal, the Funds may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Funds and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Funds' Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. Each Fund may not always achieve its investment goal. Except as otherwise noted, approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or any of its investment strategies.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS
When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms. In a dollar roll, a Fund sells a security and simultaneously enters into a commitment to purchase a similar security at a later date. Dollar rolls also involve the risk that the other party may not honor the contract terms.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as mortgages and student loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors.

Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed


35

Other Investment Strategies and Risks

through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MUNICIPAL LEASE OBLIGATIONS

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts. Municipal leases are issued by state and local governments and authorities to acquire property or equipment. They frequently involve special risks not normally associated with general obligation bonds or special revenue obligations. Municipal lease obligations may not be backed by the issuing municipality, and many have a "non-appropriation" clause. A non-appropriation clause relieves the issuer of any lease obligation from making future payments under the lease unless money is appropriated for such purpose on a periodic basis. In addition, such lease obligation payments to a Fund may be suspended if the issuing municipality is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. The disposition of the property in the event of non-appropriation or foreclosure may be difficult, time-consuming and costly and may result in a delay in recovery or the failure to fully recover the Fund's original investment.

INVERSE FLOATING RATE OBLIGATIONS

Inverse floating rate obligations represent interests in bonds. They carry coupon rates that vary inversely to changes in short-term rates. As short-term rates rise, inverse floaters produce less income and as short-term rates fall, inverse floaters produce more income. In addition, prices of inverse floaters are more volatile than prices of bonds with similar maturities. The market value of inverse floaters falls when long-term rates rise, but will fall further than the market value of a bond with a similar maturity (and will also increase more when long-term rates fall). The advisor has set an internal policy to invest no more than 15% of a Fund's total assets in inverse floating rate obligations.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend a Fund's normal investment activities. During such times, a Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

Financial Highlights

The financial highlights table is intended to help you understand the Funds' financial performance. Information is shown for the Funds' last six fiscal periods, which run from November 1 to October 31, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the applicable Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Funds' financial statements which, for the fiscal years ended October 31, 2005 and 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Funds' financial statements, is included in the Funds' annual report. For the New York Fund, the information for the period ended October 31, 2003 and for the fiscal years ended January 31, 2003, 2002 and 2001 has been derived from the Fund's financial statements, which have also been audited by PricewaterhouseCoopers, whose report expressed an unqualified opinion on those financial statements and highlights. For the California Fund, Connecticut Fund and Massachusetts Fund, the information for the period ended October 31, 2003 and for the fiscal years ended January 31, 2003, 2002 and 2001, has been derived from the Funds' financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Funds, including investment advisory fees and other Fund costs, on the Funds' returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, and C shares of the Funds assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that the all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Funds, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

The Funds -- Columbia Tax-Exempt Fund
---------------------------------------

INVESTMENT GOAL

The Fund seeks as high a level of after-tax total return as is consistent with prudent risk, by pursuing current income exempt from federal income tax and opportunities for long-term appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its total assets in tax-exempt bonds. Under normal market conditions, the Fund invests at least 65% of its total assets in tax-exempt bonds that are rated investment grade, which means that they are rated at least BBB (or Baa) by a nationally recognized rating agency. Bonds subject to the alternative minimum tax will not be counted for purposes of the 80% test described above. The Fund's investment advisor may purchase bonds of any maturity.

The Fund may invest up to 35% of its total assets in any combination of the following bonds (not including pre-refunded bonds): (i) bonds rated below investment grade by a nationally recognized rating agency and (ii) bonds that are not rated, provided that the Fund's total investments in unrated bonds may not exceed 25% of its total assets.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and nonhedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of municipal securities.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."


UNDERSTANDING TAX-EXEMPT BONDS

Tax-exempt bonds are issued by state and local governments for various public purposes. The interest on tax-exempt bonds, typically, is not subject to federal income tax. As a result, the yields on tax-exempt securities are generally lower than the yields on taxable bonds with similar maturities. However, a portion or all of such interest may be subject to a shareholder's federal alternative minimum tax liability. Tax-exempt bond funds may be appropriate for investors in high tax brackets who seek current income that is free from federal tax.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal security holders. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

The Funds -- Columbia Tax-Exempt Fund

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally-owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. The bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

Derivatives involve special risks and may result in losses. The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts, and inverse floaters to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to fund a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

The interest income distributed by the Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Funds -- Columbia Tax-Exempt Fund

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. All information in this prospectus relating to the Fund for periods prior to September 19, 2005, including the performance information shown below, is that of Columbia Tax-Exempt Fund, a series of Columbia Funds Trust IV, the predecessor to the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Municipal Bond Index ("Lehman Index"), an unmanaged index considered representative of the broad market for investment-grade, tax-exempt bonds with a maturity of at least one year. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper General Municipal Debt Funds Category ("Lipper Average"), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from the capital loss on the after tax return calculation.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $ 10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

Previously, the advisor had, with respect to the period from November 1, 2004 to February 9, 2005, waived a portion of its fees, so that it retained fees at the new contractual rate.
(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table the 12b-1 fee for Class C shares would be 0.80% and total annual fund operating expenses for Class C shares would be 1.39%. This arrangement may be modified or terminated by the distributor at any time.
(3) Other expenses have been restated to reflect contractual changes to the pricing and bookkeeping fees and transfer agency fees for the Fund effective November 1, 2005.

The Funds -- Columbia Tax-Exempt Insured Fund
-------------------------------------------------------------------------------------

INVESTMENT GOAL

The Fund seeks as high a level of after-tax total return as is consistent with prudent risk, by pursuing current income exempt from federal income tax and opportunities for long-term appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its total assets in tax-exempt bonds that are fully insured as to the payment of interest and principal. As an alternative to purchasing insured bonds, the investment advisor may purchase uninsured bonds and simultaneously purchase insurance for these bonds. The remaining 20% of the Fund's total assets may be invested in uninsured tax-exempt bonds. Under normal market conditions, the Fund invests all of its assets in tax-exempt bonds that are rated investment-grade, which means that they are rated at least BBB (or Baa) by a nationally recognized rating agency. The Fund's investment advisor currently anticipates that most of the insured bonds purchased by the Fund will have the highest credit rating given by a nationally recognized rating agency. Not more than 20% of the Fund's total assets will be rated BBB or Baa. Bonds subject to alternative minimum tax will not be counted for purposes of the 80% test described above.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and nonhedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of municipal securities.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."


UNDERSTANDING TAX-EXEMPT BONDS

Tax-exempt bonds are issued by state and local governments for various public purposes. The interest on tax-exempt bonds, typically, is not subject to federal income tax. As a result, the yields on tax-exempt securities are generally lower than the yields on taxable bonds with similar maturities. However, a portion or all of such interest may be subject to a shareholder's federal alternative minimum tax liability. Tax-exempt bond funds may be appropriate for investors in high tax brackets who seek current income that is free from federal tax.

UNDERSTANDING TAX-EXEMPT INSURANCE

The insurance feature of the Fund's tax-exempt bonds helps to reduce certain financial risks. The insurance may take any of the following forms: (i) the issuer of the bond obtains the insurance at the time the bond is issued;
(ii) the Fund buys uninsured tax-exempt bonds and simultaneously insures these specific bonds until their maturity date; and (iii) the Fund buys an insurance policy to cover specific bonds only while the Fund holds the bonds.

The Funds -- Columbia Tax-Exempt Insured Fund

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal security holders. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally-owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. The bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.

The Funds -- Columbia Tax-Exempt Insured Fund

Derivatives involve special risks and may result in losses. The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts, and inverse floaters to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to fund a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

The interest income distributed by the Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

While insurance reduces credit risk by insuring that the Fund will receive payment of principal and interest, it does not protect against fluctuations in the value of the Fund's shares caused by changes in interest rates or other factors. Also, insurance premiums, which are paid from the Fund's assets, reduce the Fund's yield.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

(1) Management fee has been restated to reflect contractual changes to the management fee for the Fund effective February 9, 2005. Previously, the advisor had, with respect to the period from November 1, 2004 to February 9, 2005, waived a portion of its fees, so that it retained fees at the new contractual rate.
(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table the 12b-1 fee for Class C shares would be 0.65% and total annual fund operating expenses would be 1.34%. This arrangement may be modified or terminated by the distributor at any time.
(3) Other expenses have been restated to reflect contractual changes to the pricing and bookkeeping fees and transfer agency fees for the Fund effective November 1, 2005.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When a Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Funds' transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide this information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of a Fund. These sales charges are described below. In certain circumstances, the sales charges may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Funds offer three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $ 1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

Columbia Tax-Exempt Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.


16

Your Account

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00

$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors will receive a 1.00% commission from the distributor on all purchases less than $3 million.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Funds and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts


18

Your Account

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information which can be obtained at www.columbiafunds.com or by calling 1-800-345-6611.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of a customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.


22

Your Account

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if a Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Funds may not be able to do anything in response to market timing that occurs in the Fund which may result in certain shareholders being able to market time the Funds while the shareholders in the Funds bear the burden of such activities.

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers")) have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Funds' practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Funds following various suspension periods.


23

Your Account

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan Each Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.20% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of each Fund's Class C share distribution fee so that it does not exceed 0.60% annually for Columbia Tax-Exempt Fund and 0.45% for Columbia Tax-Exempt Insured Fund. These arrangements may be modified or terminated by the distributor at any time. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Funds on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How a Fund's Share Price is Determined The price of each class of a Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

Each Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's shares outstanding. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Funds' transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Funds. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions, and Taxes The Funds have the potential to make the following distributions:

Types of Distributions

Dividends     Represents interest and dividends earned from securities
              held by the Funds, net of expenses incurred by each Fund.
--------------------------------------------------------------------------
Capital gains Represents net long-term capital gains on sales of
              securities held for more than 12 months and net short-term
              capital gains which are gains on sales of securities held
              for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of a Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


25

Your Account

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, each Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable all subsequent distributions will be reinvested in additional shares of the Fund.

Tax Consequences For federal income tax purposes, distributions of investment income by a Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by a Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in a Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. Each Fund intends to distribute federally tax-exempt income. Each Fund may invest a portion of its assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor on federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Funds' investment advisor. Columbia Advisors is responsible for the Funds' management, subject to oversight by the Funds' Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Funds' day-to-day business, including placing all orders for the purchase and sale of the Funds' portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management"), merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by Columbia Tax-Exempt Fund and Columbia Tax-Exempt Insured Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Funds, amounted to 0.49% and 0.48% of average daily net assets of the Funds, respectively. A discussion of the factors considered by the Funds' Boards of Trustees in approving the Funds' investment advisory contracts is included in the Funds' annual reports to shareholders for the fiscal year ended November 30, 2005.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the ''MDL''). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.


28

Managing the Funds

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under
Section 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

Other Investment Strategies and Risks
---------------------------------------

Each Fund's principal investment strategies and their associated risks are described under "The Funds --Principal Investment Strategies" and "The Funds -- Principal Investment Risks". This section describes other investments the Funds may make and the risks associated with them. In seeking to achieve their investment goal, the Funds may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Funds and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Funds' Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Funds may not always achieve their investment goal. Except as otherwise noted, approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or any of its investment strategies.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS
When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms. In a dollar roll, a Fund sells a security and simultaneously enters into a commitment to purchase a similar security at a later date. Dollar rolls also involve the risk that the other party may not honor the contract terms.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to a Fund and distributed to its shareholders.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as mortgages and student loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.


30

Other Investment Strategies and Risks

MUNICIPAL LEASE OBLIGATIONS

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts. Municipal leases are issued by state and local governments and authorities to acquire property or equipment. They frequently involve special risks not normally associated with general obligation bonds or special revenue obligations. Municipal lease obligations may not be backed by the issuing municipality, and many have a "non-appropriation" clause. A non-appropriation clause relieves the issuer of a lease obligation from making future payments under the lease unless money is appropriated for such purpose on a periodic basis. In addition, such lease obligation payments to a Fund may be suspended if the issuing municipality is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. The disposition of the property in the event of non-appropriation or foreclosure may be difficult, time-consuming and costly and may result in a delay in recovery or the failure to fully recover the Fund's original investment.

INVERSE FLOATING RATE OBLIGATIONS

Inverse floating rate obligations represent interests in bonds. They carry coupon rates that vary inversely to changes in short-term rates. As short-term rates rise, inverse floaters produce less income and as short-term rates fall, inverse floaters produce more income. In addition, prices of inverse floaters are more volatile than prices of bonds with similar maturities. The market value of inverse floaters falls when long-term rates rise, but will fall further than the market value of a bond with a similar maturity (and will also increase more when long-term rates fall). The advisor has set an internal policy to invest no more than 15% of a Fund's total assets in inverse floating rate obligations.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend a Fund's normal investment activities. During such times, a Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

Financial Highlights

The financial highlights table is intended to help you understand the Funds' financial performance. Information is shown for the Funds' last five fiscal years, which run from December 1 to November 30, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the tables represent the rate that you would have earned (or lost) on an investment in the Funds (assuming reinvestment of all dividends and distributions). This information has been derived from the Funds' financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Funds' financial statements, is included in each Fund's annual report.

(a) Per share data was calculated using average shares outstanding during the period.
(b) Effective December 1, 2001, the Fund adopted the provision of the AICPA Audit and Accounting Guide for Investment Companies and began accreting market discount on all debt securities. The effect of this change for the year ended November 30, 2002 was to increase the ratio of net investment income to average net assets from 3.61% to 3.65%. The impact to the net investment income and net realized and unrealized gain per share was less than $0.01. Per share data and ratios for periods prior to November 30, 2002 have not been restated to reflect this change in presentation.

(c) Total return at net asset value assuming all distributions reinvested and no contingent deferred sales charge.
(d) Had the investment advisor, distributor and/or transfer agent not waived a portion of expenses, total return would have been reduced.
(e) The benefits derived from custody credits had an impact of less than 0.01%.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Funds, including investment advisory fees and other Fund costs, on the Funds' returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Funds assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Funds, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

The Fund

INVESTMENT GOAL

The Fund seeks as high a level of after-tax total return as is consistent with prudent risk, by pursuing current income exempt from federal income tax and opportunities for long-term appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its total assets in tax-exempt bonds. Under normal market conditions, the Fund invests at least 65% of its total assets in tax-exempt bonds that are rated investment grade, which means that they are rated at least BBB (or Baa) by a nationally recognized rating agency. Bonds subject to the alternative minimum tax will not be counted for purposes of the 80% test described above. The Fund's investment advisor may purchase bonds of any maturity.

The Fund may invest up to 35% of its total assets in any combination of the following bonds (not including pre-refunded bonds): (i) bonds rated below investment grade by a nationally recognized rating agency and (ii) bonds that are not rated, provided that the Fund's total investments in unrated bonds may not exceed 25% of its total assets.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the municipal bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of municipal securities.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."


UNDERSTANDING TAX-EXEMPT BONDS

Tax-exempt bonds are issued by state and local governments for various public purposes. The interest on tax-exempt bonds, typically, is not subject to federal income tax. As a result, the yields on tax-exempt securities are generally lower than the yields on taxable bonds with similar maturities. However, a portion or all of such interest may be subject to a shareholder's federal alternative minimum tax liability. Tax-exempt bond funds may be appropriate for investors in high tax brackets who seek current income that is free from federal tax.

The Fund

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. The municipal securities market is also subject to uncertainties related to taxation, changes in legislation and the rights of municipal security holders. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Credit risk is the possibility that changes in the obligated entity's financial condition, changes in general economic conditions, or changes in economic conditions that affect the obligated entity, may impact the obligated entity's actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and, in some cases, a decrease in income. Bonds that are backed by an issuer's taxing authority, including general obligation bonds, may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. These bonds may depend for payment on legislative appropriation and/or aid from other governments. Other municipal bonds, known as revenue obligations, are payable from revenues earned by a particular project or other revenue source. Some revenue obligations are backed by private companies, some are asset-backed securities, such as bonds backed by mortgage payments, and some are for municipally-owned utilities, such as water or sewer systems. Revenue obligations are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project, assets, or private company backing the project, rather than to the taxing power of the state or local government issuer of the bonds.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Tax-exempt bonds are subject to special risks. Changes in tax laws or adverse determinations by the Internal Revenue Service may make the income from some of these bonds taxable. Bonds that are backed by the issuer's taxing authority, known as general obligation bonds, may depend for payment on legislative appropriation and/or aid from other governments. The bonds may be vulnerable to legal limits on a government's power to raise revenue or increase taxes. Other tax-exempt bonds, known as special revenue obligations, are payable from revenues earned by a particular project or other revenue sources. These bonds are subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or the private company backing the project, rather than to the credit of the state or local government issuer of the bonds.


3

The Fund

Derivatives involve special risks and may result in losses. The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts, and inverse floaters to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to fund a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

The interest income distributed by the Fund from certain tax-exempt bonds may be subject to the federal alternative minimum tax for individuals and corporations. As a fundamental policy that cannot be changed without shareholder approval, the Fund may not invest more than 20% of its total assets in bonds subject to the alternative minimum tax. Consult your tax advisor for more information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. All information in this prospectus relating to the Fund for periods prior to September 19, 2005, including the performance information shown below, is that of Columbia Tax-Exempt Fund, a series of Columbia Funds Trust IV, the predecessor to the Fund. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

The Fund


UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses. Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses./(1)/
The Fund's returns are compared to the Lehman Brothers Municipal Bond Index ("Lehman Index"), an unmanaged index considered representative of the broad market for investment-grade, tax-exempt bonds with a maturity of at least one year. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper General Municipal Debt Funds Category ("Lipper Average"), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.

(1) Class Z is a newer class of shares. Its performance information consists of returns of the Fund's Class A shares (the oldest existing fund class). These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees.

If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on November 21, 1978, and Class Z shares were initially offered on September 16, 2005.

The Fund

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The return after taxes on distributions and sale of fund shares at a capital loss may be higher than the return before taxes due to the resulting tax benefit from capital loss on the after tax return calculation.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

(1) Because Class Z has not been offered for a full calendar year, the expenses provided are estimates based on Class A shares for its last fiscal year.

The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a Fund with different pricing options. This allows you and your financial adviser to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial adviser offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations, purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for eligible investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Fund may not be able to do anything in response to market timing that occurs in the Fund which may result in certain shareholders being able to market time the Fund while the shareholders in the Fund bear the burden of such activities.

Certain financial intermediaries (including certain retirement service plan providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers")) have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Fund following various suspension periods.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive the day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.


14

Your Account

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

---------------------------------------------------------------------------
  Reinvest all distributions in shares of another fund

Tax Consequences For federal income tax purposes, distributions of investment income by the Fund, whether in cash or additional securities, will ordinarily constitute tax-exempt income. Generally, gains realized by the Fund on the sale or exchange of investments, the income from which is tax-exempt, will be taxable to shareholders. In addition, an investment in the Fund may result in liability for federal alternative minimum tax for both individuals and corporate shareholders. The Fund intends to distribute federally tax-exempt income. The Fund may invest a portion of its assets in securities that generate income subject to federal or state income taxes. Income exempt from federal tax may be subject to state and local taxes.

You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.49% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended November 30, 2005.

PORTFOLIO MANAGER

Kimberly Campbell, a senior vice president of Columbia Advisors, is the manager for the Fund and has managed the Fund since May, 2004 and served as a portfolio manager from January, 2002 to March, 2004. Ms. Campbell was on a leave of absence for the period March, 2004 to May, 2004. Ms. Campbell has been associated with Columbia Advisors or its predecessors since June, 1995.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


17

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.


18

Managing the Fund

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

Other Investment Strategies and Risks
---------------------------------------

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risk." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS
When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms. In a dollar roll, a Fund sells a security and simultaneously enters into a commitment to purchase a similar security at a later date. Dollar rolls also involve the risk that the other party may not honor the contract terms.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as mortgages and student loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

Other Investment Strategies and Risks

MUNICIPAL LEASE OBLIGATIONS

Municipal lease obligations are revenue bonds backed by leases or installment purchase contracts. Municipal leases are issued by state or local governments and authorities to acquire property or equipment. They frequently involve special risks not normally associated with general obligation bonds or special revenue obligations. Municipal lease obligations may not be backed by the issuing municipality, and many have a "non-appropriation" clause. A non-appropriation clause relieves the issuer of a lease obligation from making future payments under the lease unless money is appropriated for such purpose on a periodic basis. In addition, such lease obligation payments to a Fund may be suspended if the issuing municipality is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. The disposition of the property in the event of non-appropriation or foreclosure may be difficult, time-consuming and costly and may result in a delay in recovery or the failure to fully recover the Fund's original investment.

INVERSE FLOATING RATE OBLIGATIONS


Inverse floating rate obligations represent interest in bonds. They carry coupon rates that vary inversely to changes in short-term rates. As short-term rates rise, inverse floaters produce less income and as short-term rates fall, inverse floaters produce more income. In addition, prices of inverse floaters are more volatile than prices of bonds with similar maturities. The market value of inverse floaters falls when long-term rates rise, but will fall further than the market value of a bond with a similar maturity (and will also increase more when long-term rates fall). The advisor has set an internal policy to invest no more than 15% of a Fund's total assets in inverse floating rate obligations.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

THE FUND

INVESTMENT GOALS

The Fund seeks current income and long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of utilities companies. Up to 20% of the Fund's net assets (plus any borrowings for investment purposes) may be invested in equity securities of non-utilities related companies. The Fund may invest up to 20% of its assets in securities of foreign utilities companies.

UTILITY COMPANY SECURITIES

Utility company securities in which the Fund may invest include securities of companies engaged in the manufacture, production, generation, transmission, sale or distribution of electricity, natural gas or other types of energy, water or other sanitary services. They also include securities of companies engaged in telecommunications, such as telephone, Internet, satellite, television, microwave and other communications media. The Fund may invest in securities of companies engaged in the manufacture and production of equipment utilized in the energy and telecommunications industries.

UNDERSTANDING VALUE INVESTING

In managing the Fund, the Fund's investment advisor uses a value investing strategy that focuses on buying stocks cheaply when they are undervalued or "out of favor." The advisor buys stocks that have attractive current prices, consistent operating performance and/or favorable future growth prospects. The advisor's strategy uses fact-based, quantitative analysis supported by fundamental business and financial analyses.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management


2

THE FUND

and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Utility company securities are subject to special risks. These securities are generally strongly affected by changes in interest rates, as well as by general competitive and market forces in the utilities industries. As interest rates increase, the value of securities of utility companies tends to decrease, and vice versa. In addition, utility companies may be affected by changes in government regulation. In particular, the value of utility company securities may be adversely affected by increased competition resulting from deregulation.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have

THE FUND

been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Standard & Poor's Utility Index ("S&P Utility Index"), an unmanaged market-cap weighted index that tracks the performance of natural gas and electric companies, and the Standard & Poor's Telecom Index ("S&P Telecom Index"), an unmanaged market-cap weighted index that tracks the performance of telecommunications companies. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

Best quarter: 2nd quarter 2003, +18.35%
Worst quarter: 3rd quarter 2002, -28.90%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class B shares for periods prior to the inception of Class C shares. Class B shares would have substantially similar annual returns because Class B and Class C shares generally have similar expense structures. Class B shares were initially offered on May 5, 1992 and Class C shares were initially offered on August 1, 1997.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

YOUR ACCOUNT

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

For certain group retirement plans, financial advisors receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint


9

YOUR ACCOUNT

discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Fund as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions


10

YOUR ACCOUNT

under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information which can be obtained at www.columbiafunds.com or by calling 1-800-345-6611.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS C SHARES Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts,


13

YOUR ACCOUNT

the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is the risk that the Fund may not be able to do anything in response to market timing that occurs in the Fund which may result in certain shareholders being able to market time the Fund while the shareholders in the Fund bear the burden of such activities.

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others, various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers") have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Fund following various suspension periods.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-l that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If

YOUR ACCOUNT

you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.


16

YOUR ACCOUNT

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, all subsequent distributions will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.65% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended November 30, 2005.

PORTFOLIO MANAGER

EDWARD PAIK, an assistant vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2002. Mr. Paik has been associated with Columbia Advisors or its predecessors since March, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS


On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud


18

MANAGING THE FUND

provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from


19

MANAGING THE FUND

contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

THE FUND

INVESTMENT GOALS

The Fund seeks current income and long-term growth.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of utilities companies. Up to 20% of the Fund's net assets (plus any borrowings for investment purposes) may be invested in equity securities of non-utilities related companies. The Fund may invest up to 20% of its assets in securities of foreign utilities companies.


UTILITY COMPANY SECURITIES

Utility company securities in which the Fund may invest include securities of companies engaged in the manufacture, production, generation, transmission, sale or distribution of electricity, natural gas or other types of energy, water or other sanitary services. They also include securities of companies engaged in telecommunications, such as telephone, Internet, satellite, television, microwave and other communications media. The Fund may invest in securities of companies engaged in the manufacture and production of equipment utilized in the energy and telecommunications industries.

UNDERSTANDING VALUE INVESTING

In managing the Fund, the Fund's investment advisor uses a value investing strategy that focuses on buying stocks cheaply when they are undervalued or "out of favor." The advisor buys stocks that have attractive current prices, consistent operating performance and/or favorable future growth prospects. The advisor's strategy uses fact-based, quantitative analysis supported by fundamental business and financial analyses.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.


2

THE FUND

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of the company's stock may fall, or may not approach the value the advisor has placed on it.

Utility company securities are subject to special risks. These securities are generally strongly affected by changes in interest rates, as well as by general competitive and market forces in the utilities industries. As interest rates increase, the value of securities of utility companies tends to decrease, and vice versa. In addition, utility companies may be affected by changes in government regulation. In particular, the value of utility company securities may be adversely affected by increased competition resulting from deregulation.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Standard & Poor's Utility Index (S&P Utility Index), an unmanaged market cap-weighted index that tracks the performance of natural gas and electric companies. The Fund's returns are also compared to the Standard & Poor's Telecom Index (S&P Telecom Index), an unmanaged market cap-weighted index that tracks the performance of telecommunications companies. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on August 3, 1981, and Class Z shares were initially offered on January 29, 1999.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order.

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by a broker/dealer, bank, third-party administrator or other financial institution (each commonly referred to as an "intermediary"). Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

NO MINIMUM INVESTMENT APPLIES TO ACCOUNTS PARTICIPATING IN THE AUTOMATIC INVESTMENT PLAN; HOWEVER, EACH INVESTMENT REQUIRES A $25 MINIMUM PURCHASE. THE FUND ALSO RESERVES THE RIGHT TO REFUSE A PURCHASE ORDER FOR ANY REASON, INCLUDING IF IT BELIEVES THAT DOING SO WOULD BE IN THE BEST INTEREST OF THE FUND AND ITS SHAREHOLDERS.

YOUR ACCOUNT

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 10 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


12

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Consequently, there is risk that the Fund may not be able to do anything in response to market timing that occurs in the Fund which may result in certain shareholders being able to market time the Fund while the shareholders in the Fund bear the burden of such activities.

Certain financial intermediaries (including certain retirement plan service providers whose clients include, among others; various retirement plans sponsored by Bank of America and its affiliates for the benefit of its employees (the "Bank of America retirement service plan providers")) have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above. In particular, the Bank of America retirement service plan provider permits the reinstatement of future purchase orders for shares of the Fund following various suspension periods.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of


13

YOUR ACCOUNT

factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to an intermediary. Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur


14

YOUR ACCOUNT

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends quarterly and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

15

YOUR ACCOUNT

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a direct, wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.65% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended November 30, 2005.

PORTFOLIO MANAGER

EDWARD PAIK, an assistant vice president of Columbia Advisors, is the manager for the Fund and has managed or co-managed the Fund since May, 2002. Mr. Paik has been associated with Columbia Advisors or its predecessors since March, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud


17

MANAGING THE FUND

provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and he has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from


18

MANAGING THE FUND

contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

SUPPLEMENT TO THE PROSPECTUS DATED AUGUST 1, 2005

COLUMBIA INCOME FUND (THE "FUND")

CLASS A, B AND C SHARES

(REPLACING SUPPLEMENTS DATED AUGUST 19, 2005 AND FEBRUARY 17, 2006)

The Fund's Prospectus is hereby supplemented with the following information:

1. The fifth paragraph under the heading "PRINCIPAL INVESTMENT STRATEGIES" is revised in its entirety as follows:

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics. The Fund may participate in mortgage dollar rolls.

2. The section under the heading "PRINCIPAL INVESTMENT RISKS" is revised to include the following:

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

3. The "Calendar Year Total Returns" and "Average Annual Total Returns" tables for the Fund in the section entitled "Performance History" are updated and restated in their entirety as follows:

CALENDAR YEAR TOTAL RETURNS

For the periods shown above:

Worst quarter: 2nd quarter 2004, -2.47%

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower, since

Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. Class B and Class C performance information includes returns of the Fund's Class A shares for the period from July 31, 2000 through July 15, 2002.

(3) These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower, since the newer classes of shares are subject to a Rule 12b-1 fee. Class A shares were initially offered on July 31, 2000, Class B and Class C shares were initially offered on July 15, 2002, and Class Z shares were initially offered on March 5, 1986.

4. The footnotes to the table entitled "Shareholder Fees" are revised to provide that the contingent deferred sales charge ("CDSC") applicable to Class A shares applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.

5. The section entitled "Investment Minimums" is revised in its entirety as follows:

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

6. The call-out box entitled "Choosing a Share Class" is revised in its entirety as follows:

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

7. The table entitled "Class A Sales Charges" is replaced in its entirety as follows:

8. The paragraph immediately following the table entitled "Class A Sales Charges" is revised in its entirety as follows:

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

9. The table entitled "Purchases Over $1 Million" for Class A shares is replaced in its entirety as follows:

-3-

PURCHASES OVER $ILLION

                                      COMMISSION %
                                      ------------

$3 million to less than $50 million       0.50
$50 million or more                       0.25

For certain group retirement plans, financial advisors will receive a 1% commission from the distributor on all purchases less than $3 million.

10. The section entitled "Reduced Sales Charges for Larger Investments" is revised in its entirety as follows:

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

-4-

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, though fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

11. All disclosure related to Class B Sales Charges under the section entitled "Sales Charges" is revised in its entirety as follows:

-5-

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

CLASS B SALES CHARGES

Automatic conversion to Class A shares occurs eight years after purchase.

12. The instructions with respect to redemptions by systematic withdrawal plan in the table under the section "How to Sell Shares" are revised in their entirety as follows:

You may automatically sell a specified dollar amount or percentage of your account on a monthly, quarterly or semi-annual basis and have the proceeds sent to you if your account balance is at least $5,000. The $5,000 minimum account balance requirement has been waived for wrap accounts. This feature is not available if you hold your shares in certificate form. All dividend and capital gains distributions must be reinvested. Be sure to complete the appropriate section of the account application for this feature.

13. Columbia Funds Distributor, Inc. (the Funds' distributor) and Columbia Funds Services, Inc. (the Funds' transfer agent) changed their names to Columbia Management Distributors, Inc. and Columbia Management Services, Inc., respectively.

14. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-

-6-

and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption

-7-

from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

15. The section entitled "FINANCIAL HIGHLIGHTS" is updated and restated in its entirety as follows:

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the fiscal year ended March 31, 2005 and the Fund's prior fiscal years, which ran from July 1 to June 30, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended September 30, 2005 is unaudited. Other information is included in the financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the periods ended June 30, 2003, 2002, and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

SUPPLEMENT TO THE PROSPECTUSES DATED AUGUST 1, 2005 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the ""Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the ""Annual Fees and Expenses" amounts shown would be higher.

The Fund

INVESTMENT GOALS

The Fund seeks its total return by investing for a high level of current income and, to a lesser extent, capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, including:

. debt securities issued by the U.S. government; these include U.S. treasury securities and agency securities; agency securities include certain mortgage-backed securities, which represent interests in pools of mortgages,

. debt securities of corporations,

. mortgage-backed securities and asset-backed securities issued by private (non-governmental) entities, and

. dollar-denominated debt securities issued by foreign governments and corporations.

At least 60% of total assets are medium- or higher-quality securities that are at the time of purchase:

. rated at least BBB by Standard & Poor's,

. rated at least Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the advisor believes to be of comparable quality.

The Fund may invest up to 40% of its total assets in lower-rated or comparable unrated debt securities. These securities are sometimes referred to as "junk bonds" and are at the time of purchase:

. rated below BBB by Standard & Poor's,

. rated below Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the advisor believes to be of comparable quality.

The Fund seeks to achieve capital appreciation through purchasing bonds that increase in market value. In addition, to a limited extent, the Fund may seek capital appreciation by using hedging techniques such as futures or options.

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics.

The Fund

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities.

Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payment of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid

The Fund

earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. The Fund's returns are compared to the Lehman Brothers Intermediate Government/Credit Bond Index (Lehman Intermediate Gov't/Credit Index), an unmanaged index that tracks the performance of intermediate term U.S. government and corporate bonds. The Fund's returns are also compared to the Lehman Brothers Intermediate Credit Bond Index (Lehman Index), the intermediate component of the U.S. Credit Index. The U.S. Credit Index includes publicly issued US corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A is a newer class of shares. Its performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer class of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been lower, since Class A shares are subject to a Rule 12b-1 fee. Class A shares were initially offered on July 31, 2000, and Class Z shares were initially offered on March 5, 1986.

These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower, since the newer classes of shares are subject to a Rule 12b-1 fee. Class A shares were initially offered on July 31, 2000, Class B and Class C shares were initially offered on July 15, 2002, and Class Z shares were initially offered on March 5, 1986.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Funds Distributor, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) The Fund pays a management fee of 0.41% and administration fee of 0.13%. Management fees have been restated to reflect contractual changes effective November 1, 2004.
(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table the 12b-1 fee for Class C shares would be 0.85% and total annual fund operating expenses for Class C shares would be 1.53%. This arrangement may be modified or terminated by the distributor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. If your financial advisor does not participate in the Class B discount program, purchases of $250,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Your Account

Class A shares bought without an initial sales charge in accounts aggregating $1 million to $25 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 18 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $25 million) are subject to a CDSC if redeemed within 18 months of the date of purchase. The 18-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                                         Commission %
Less than $3 million                                         1.00
---------------------------------------------------------------------
$3 million to less than $5 million                           0.80
---------------------------------------------------------------------
$5 million to less than $25 million                          0.50
---------------------------------------------------------------------
$25 million or more                                          0.25

The commission to financial advisors for Class A share purchases of $25 million or more is paid over 12 months but only to the extent the shares remain outstanding.

For Class A share purchases by participants in certain group retirement plans offered through a fee-based program, financial advisors receive a 1.00% commission from the distributor on all purchases of less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the


11

Your Account

Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information. Upon request, a Statement of Intent may apply to purchases made 90 days prior to the date the Statement of Intent is received by the Fund.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission. For purposes of obtaining either breakpoint discount, purchases of Galaxy money market funds are not included.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Funds Services, Inc., you will need to provide the foregoing information to a Columbia Funds Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

Purchases of less than $250,000:

Commission to financial advisors is 4.00%.

Automatic conversion to Class A shares occurs eight years after purchase.

You can pay a lower CDSC and reduce the period during which a CDSC would apply when making purchases of Class B shares through a financial advisor that participates in the Class B share discount program for larger purchases as described in the charts below. Some financial advisors are not able to participate because their record keeping or transaction processing systems are not designed to accommodate these reductions. For non-participating financial advisors, purchases of Class B shares must be less than $250,000. Consult your financial advisor to see whether it participates in the discount program for larger purchases. For participating financial advisors, Rights of Accumulation (as described above) apply, so that if the combined value of the eligible Fund accounts in all classes maintained by you and each member of your immediate family (as defined above), together with the value of your current purchase, is at or above a discount level, your current purchase will be subject to a lower CDSC and the applicable reduced holding period, provided that you have notified your financial advisor in writing of the identity of such other accounts and your relationship to the other account holders. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. This Class B share discount program for larger purchases (as further described in the charts below) is not applicable to Class B shares received by former Galaxy Fund Prime B shareholders in connection with the reorganization of the former Galaxy Fund.

Your financial advisor will receive the lower commission for purchases in excess of the applicable discount level. If you exchange from a participating fund or transfer your account from a financial advisor that does participate in the program into a non-participating fund or to a financial advisor that does not participate in the program, the exchanged or transferred shares will retain the pre-existing CDSC schedule and holding period but all additional purchases of Class B shares will be subject to the higher CDSC and longer holding period of the non-participating fund or applicable to the non-participating financial advisor.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays the financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

Outlined below are the various options for selling shares:

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-


16

Your Account

round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan. The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Class C share distribution fee so that it does not exceed 0.60% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after a certain number of years, eliminating the distribution fee upon conversion. Conversion may occur three, four or eight years after purchase, depending on the program under which you purchased your shares. See "Your Account -- Sales Charges" for the conversion schedules applicable to Class B shares.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial


17

Your Account

institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub- transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which the Fund shares are priced. If a security is valued at a "fair value" that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution

which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Management runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities.

Columbia Management, a registered investment advisor, has been an investment advisor since 1969.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.45% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended March 31, 2005.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight

structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC, to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant, who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the Funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the Funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the Funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors.

Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.


23

Other Investment Strategies and Risks

Commercial mortgage-backed securities are secured by loans to commercial properties such as office buildings, multi-family apartment buildings, and shopping centers. These loans usually contain prepayment penalties that provide protection from refinancing in a declining interest rate environment.

Real estate mortgage investment conduits (REMICs) are multi-class securities that qualify for special tax treatment under the Internal Revenue Code. REMICs invest in certain mortgages that are secured principally by interests in real property such as single family homes.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year to year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although, to a limited extent, it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold in public transactions because of Securities and Exchange Commission regulations (these are known as "restricted securities"). Under procedures adopted by the Fund's Board of Trustees, certain restricted securities may be deemed liquid and will not be counted towards this 15% limit.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

SUPPLEMENT TO THE PROSPECTUS DATED AUGUST 1, 2005

COLUMBIA INCOME FUND (THE "FUND")

CLASS Z SHARES

(REPLACING SUPPLEMENTS DATED AUGUST 19, 2005 AND FEBRUARY 17, 2006)

The Fund's Prospectus is hereby supplemented with the following information:

1. The fifth paragraph under the heading "PRINCIPAL INVESTMENT STRATEGIES" is revised in its entirety as follows:

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics. The Fund may participate in mortgage dollar rolls.

2. The section under the heading "PRINCIPAL INVESTMENT RISKS" is revised to include the following:

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

3. The section entitled "Eligible Investors" was revised in its entirety as follows:

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

-2-

The Funds reserve the right to change the criteria for eligible investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Funds also reserve the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

4. Columbia Funds Distributor, Inc. (the Funds' distributor) and Columbia Funds Services, Inc. (the Funds' transfer agent) changed their names to Columbia Management Distributors, Inc. and Columbia Management Services, Inc., respectively.

5. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

7. The section entitled "FINANCIAL HIGHLIGHTS" is updated and restated in its entirety as follows:

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the fiscal year ended March 31, 2005 and the Fund's prior fiscal years, which ran from July 1 to June 30, unless otherwise indicated. The Fund did not have separate classes of shares prior to July 31, 2000. On that date, the Fund's outstanding shares were redesignated as Class S shares and on July 15, 2002, Class S shares were redesignated as Class Z shares. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended September 30, 2005 is unaudited. Other information has been derived from the Fund's financial statements which, for the fiscal year ended March 31, 2005 and for the period ended March 31, 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the years ended June 30, 2003, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Selected data for a share outstanding throughout each period is as follows:

The Fund

INVESTMENT GOALS

The Fund seeks its total return by investing for a high level of current income and, to a lesser extent, capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, including:

. debt securities issued by the U.S. government; these include U.S. treasury securities and agency securities; agency securities include certain mortgage-backed securities, which represent interests in pools of mortgages,

. debt securities of corporations,

. mortgage-backed securities and asset-backed securities issued by private (non-governmental) entities, and

. dollar-denominated debt securities issued by foreign governments and corporations.

At least 60% of total assets are medium- or higher-quality securities that are at the time of purchase:

. rated at least BBB by Standard & Poor's,

. rated at least Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the advisor believes to be of comparable quality.

The Fund may invest up to 40% of its total assets in lower-rated or comparable unrated debt securities. These securities are sometimes referred to as "junk bonds" and are at the time of purchase:

. rated below BBB by Standard & Poor's,

. rated below Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the advisor believes to be of comparable quality.

The Fund seeks to achieve capital appreciation through purchasing bonds that increase in market value. In addition, to a limited extent, the Fund may seek capital appreciation by using hedging techniques such as futures or options.

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency.

The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payment of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

The Fund

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The Fund did not have separate classes of shares prior to July 31, 2000; on that date, the Fund's outstanding shares were redesignated as Class S shares and on July 15, 2002, Class S shares were redesignated as Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers Intermediate Government/Credit Bond Index, (Lehman Intermediate Gov't/Credit Index), an unmanaged index that tracks the performance of U.S. government and corporate bonds. The Fund's returns are also compared to the Lehman Brothers Intermediate Credit Bond Index (Lehman Index) the intermediate component of the U.S. Credit Index. The U.S. Credit Index includes publicly issued US corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important things to consider when deciding on a Class of shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Funds Distributor, Inc.


8

Your Account

(i) who holds Class Z shares; (ii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iii) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Funds Distributor, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Funds Distributor, Inc. ;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement); or

. Any insurance company, trust company, bank, endowment, investment company or foundation purchasing shares for its own account.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $50 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased, or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all the information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" also means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


11

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will


12

Your Account

not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which the Fund shares are priced. If a security is valued at a "fair value" that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.


13

Your Account

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance,


15

Managing the Fund

control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC, to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant, who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the Funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the Funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the Funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors.

Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.


17

Other Investment Strategies and Risks

Commercial mortgage-backed securities are secured by loans to commercial properties such as office buildings, multi-family apartment buildings, and shopping centers. These loans usually contain prepayment penalties that provide protection from refinancing in a declining interest rate environment.

Real estate mortgage investment conduits (REMICs) are multi-class securities that qualify for special tax treatment under the Internal Revenue Code. REMICs invest in certain mortgages that are secured principally by interests in real property such as single family homes.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year to year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although, to a limited extent, it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold in public transactions because of Securities and Exchange Commission regulations (these are known as "restricted securities"). Under procedures adopted by the Fund's Board of Trustees, certain restricted securities may be deemed liquid and will not be counted towards this 15% limit.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the fiscal year ended March 31, 2005 and the Fund's prior fiscal years, which ran from July 1 to June 30, unless otherwise indicated. The Fund did not have separate classes of shares prior to July 31, 2000. On that date, the Fund's outstanding shares were redesignated as Class S shares and on July 15, 2002, Class S shares were redesignated as Class Z shares. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the fiscal year ended March 31, 2005 and for the period ended March 31, 2004, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the years ended June 30, 2003, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED AUGUST 1, 2005 (THE "PROSPECTUS")
(REPLACING SUPPLEMENTS DATED AUGUST 19, 2005)

COLUMBIA INTERMEDIATE BOND FUND

CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. Columbia Funds Distributor, Inc. (the Funds' distributor) and Columbia Funds Services, Inc. (the Funds' transfer agent) changed their names to Columbia Management Distributors, Inc. and Columbia Management Services, Inc., respectively.

4. The following disclosure is added under the heading "PRINCIPAL INVESTMENT STRATEGIES":

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

5. The following disclosure is added under the heading "PRINCIPAL INVESTMENT RISKS":

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors. Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies:
Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the


future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

6. The "CALENDAR YEAR TOTAL RETURNS" and "AVERAGE ANNUAL TOTAL RETURNS" tables for the Fund in the section entitled "PERFORMANCE HISTORY" are updated and restated in their entirety as follows:

(1) Class A, B and C are newer classes of shares. Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. Class B and Class C performance information includes returns of the Fund's Class A shares for the period from July 31, 2000 through February 1, 2002.


(2) Class A, B and C are newer classes of shares. Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. Class B and Class C performance information includes returns of the Fund's Class A shares for the period from July 31, 2000 through February 1, 2002 and for the periods prior thereto, the Fund's Class Z shares (the oldest existing Fund class).

(3) These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower, since the newer classes of shares are subject to a Rule 12b-1 fee. Class A shares were initially offered on July 31, 2000, Class B and C shares were initially offered on February 1, 2002 and Class Z shares were initially offered on December 5, 1978. On July 29, 2002, Class S shares were redesignated as Class Z shares. Class Z shares are not offered in this Prospectus.

7. The footnotes to the table entitled "SHAREHOLDER FEES" are revised to provide that the contingent deferred sales charge ("CDSC") applicable to Class A shares applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.

8. The section entitled "INVESTMENT MINIMUMS" is revised in its entirety as follows: The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

9. The call-out box entitled "CHOOSING A SHARE CLASS" is revised in its entirety as follows:

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.


10. The table entitled "CLASS A SALES CHARGES" is replaced in its entirety as follows:

11. The paragraph immediately following the table entitled "CLASS A SALES CHARGES" is revised in its entirety as follows:

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

12. The table entitled "PURCHASES OVER $1 MILLION" for Class A shares is replaced in its entirety as follows:

PURCHASES OVER $1 MILLION

AMOUNT PURCHASED                      COMMISSION %
----------------                      ------------

$3 million to less than $50 million       0.50
$50 million or more                       0.25

For certain group retirement plans, financial advisors will receive a 1% commission from the distributor on all purchases less than $3 million.

13. The section entitled "REDUCED SALES CHARGES FOR LARGER INVESTMENTS" is revised in its entirety as follows:

A. WHAT ARE THE PRINCIPAL WAYS TO OBTAIN A BREAKPOINT DISCOUNT?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.


RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. WHAT ACCOUNTS ARE ELIGIBLE FOR BREAKPOINT DISCOUNTS?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. HOW DO I OBTAIN A BREAKPOINT DISCOUNT?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor


and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. HOW CAN I OBTAIN MORE INFORMATION ABOUT BREAKPOINT DISCOUNTS?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, though fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

14. All disclosure related to Class B Sales Charges under the section entitled "SALES CHARGES" is revised in its entirety as follows:

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

Purchases of less than $50,000

CLASS B SALES CHARGES

                                % DEDUCTED WHEN

Longer than six years                 0.00

Commission to financial advisors is 2.75%.

Automatic conversion to Class A shares occurs eight years after purchase.


15. The instructions with respect to redemptions by systematic withdrawal plan in the table under the section "HOW TO SELL SHARES" are revised in their entirety as follows:

You may automatically sell a specified dollar amount or percentage of your account on a monthly, quarterly or semi-annual basis and have the proceeds sent to you if your account balance is at least $5,000. The $5,000 minimum account balance requirement has been waived for wrap accounts. This feature is not available if you hold your shares in certificate form. All dividend and capital gains distributions must be reinvested. Be sure to complete the appropriate section of the account application for this feature.

16. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.


In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

17. The disclosure titled "MORTGAGE-BACKED SECURITIES" under the heading "OTHER INVESTMENT STRATEGIES AND RISKS" is deleted in its entirety.


18. The section entitled "FINANCIAL HIGHLIGHTS" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's fiscal years since inception, which run from April 1 to March 31, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended September 30, 2005 is unaudited. Other information has been derived from the Fund's financial statements which for the year ended March 31, 2005 and the period ended March 31, 2004, have been audited by PricewaterhouseCoopers LLP, independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the periods ended June 30, 2003, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

The Fund

INVESTMENT GOALS

The Fund seeks its total return by pursuing current income and opportunities for capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, including:

. debt securities issued by the U.S. government, including U.S. treasury securities and agency securities (agency securities include certain mortgage-backed securities, which represent interests in pools of mortgages),

. debt securities of corporations, and

. mortgage-backed securities and asset-backed securities issued by private (non-governmental) entities.

The Fund will invest at least 60% of its net assets in high-quality debt securities that are at the time of purchase:

. rated at least A by Standard & Poor's,

. rated at least A by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

The Fund may invest up to 20% of its net assets in lower-rated debt securities. These securities are sometimes referred to as "junk bonds" and are at the time of purchase:

. rated below BBB by Standard & Poor's,

. rated below Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

Normally, the Fund expects to maintain a dollar-weighted average effective maturity of three to ten years.

The Fund seeks to achieve capital appreciation through purchasing bonds that increase in market value.

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics. The advisor may be required to sell portfolio investments to fund redemptions.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's

The Fund

sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payment of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid

The Fund

earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Reinvestment Risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Fund

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Aggregate Bond Index (Lehman Aggregate Index), a market value-weighted index that tracks fixed-rate, publicly placed, dollar-dominated, and non-convertible investment grade debt issues. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class A, B and C are newer classes of shares. Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. Class B and Class C performance information includes returns of the Fund's Class A shares for the period from July 31, 2000 through February 1, 2002 and for the periods prior thereto, the Fund's Class Z shares (the oldest existing Fund class). These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower, since the newer classes of shares are subject to a Rule 12b-1 fee. Class A shares were initially offered on July 31, 2000, Class B and C shares were initially offered on February 1, 2002 and Class Z shares were initially offered on December 5, 1978. On July 29, 2002, Class S shares were redesignated as Class Z shares. Class Z shares are not offered in this Prospectus.

The Fund

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Funds Distributor, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class A and C shares. If this waiver were reflected in the table, the 12b-1 fee for Class A and C shares would be 0.25% and 0.85%, respectively, and total annual fund operating expenses for Class A and C shares would be 0.94% and 1.54%, respectively. This arrangement may be modified or terminated by the distributor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all the information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, these sales charges may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. If your financial advisor does not participate in the Class B discount program, purchases of $250,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

                                                                      % of offering price

Your Account

Class A shares bought without an initial sales charge in accounts aggregating $1 million to $25 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 18 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $25 million) are subject to a CDSC if redeemed within 18 months of the date of purchase. The 18-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $5 million      0.80
------------------------------------------------
$5 million to less than $25 million     0.50
------------------------------------------------
$25 million or more                     0.25

The commission to financial advisors for Class A share purchases of $25 million or more is paid over 12 months but only to extent the shares remain outstanding.

For Class A share purchases by participants in certain group retirement plans offered through a fee-based program, financial advisors receive a 1.00% commission from the distributor on all purchases of less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.


11

Your Account

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information. Upon request, a Statement of Intent may apply to purchases made 90 days prior to the date the Statement of Intent is received by the Fund.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission. For purposes of obtaining either breakpoint discount, purchases of Galaxy money market funds are not included.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Funds Services, Inc., you will need to provide the foregoing information to a Columbia Funds Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

Purchases of less than $250,000:

Commission to financial advisors is 4.00%.

Automatic conversion to Class A shares occurs eight years after purchase.

You can pay a lower CDSC and reduce the period during which a CDSC would apply when making purchases of Class B shares through a financial advisor that participates in the Class B share discount program for larger purchases as described in the charts below. Some financial advisors are not able to participate because their record keeping or transaction processing systems are not designed to accommodate these reductions. For non-participating financial advisors, purchases of Class B shares must be less than $250,000. Consult your financial advisor to see whether it participates in the discount program for larger purchases. For participating financial advisors, Rights of Accumulation (as described above) apply, so that if the combined value of the eligible Fund accounts in all classes maintained by you and each member of your immediate family (as defined above), together with the value of your current purchase, is at or above a discount level, your current purchase will be subject to a lower CDSC and the applicable reduced holding period, provided that you have notified your financial advisor in writing of the identity of such other accounts and your relationship to the other account holders. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. This Class B share discount program for larger purchases (as further described in the charts below) is not applicable to Class B

If you exchange into a fund participating in the Class B share discount program or transfer your fund account from a financial advisor that does not participate in the program to one that does, the exchanged or transferred shares will retain the pre-existing CDSC but any additional purchases of Class B shares which, together with the exchanged or transferred account, exceed the applicable discount level will be subject to the lower CDSC and the reduced holding period for amounts in excess of the discount level. Your financial advisor will receive the lower commission for purchases in excess of the applicable discount level. If you exchange from a participating fund or transfer your account from a financial advisor that does participate in the program into a non-participating fund or to a financial advisor that does not participate in the program, the exchanged or transferred shares will retain the pre-existing CDSC schedule and holding period but all additional purchases of Class B shares will be subject to the higher CDSC and longer holding period of the non-participating fund or applicable to the non-participating financial advisor.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays the financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all of the information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" also means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) you have included any certificates for shares to be sold and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


16

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.10% for Class A shares and 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive the Class A share distribution fee and a portion of the Class C share distribution fee so that it does not exceed 0.60% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after a certain number of years, eliminating a portion of the distribution fee upon conversion. Conversion may occur three, four or eight years after purchase, depending on the program under which you purchased your shares. See "Your Account; Sales Charges" for the conversion schedules applicable to Class B shares.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur


18

Your Account

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions, and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day
before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer


19

Your Account

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

INVESTMENT ADVISOR

Columbia Management Advisors, Inc. ("Columbia Management"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Management is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Management runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures


21

Managing the Fund

designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC, to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant, who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the Funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the Funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the Funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described above under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors.

Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.


23

Other Investment Strategies and Risks

Commercial mortgage-backed securities are secured by loans to commercial properties such as office buildings, multi-family apartment buildings, and shopping centers. These loans usually contain prepayment penalties that provide protection from refinancing in a declining interest rate environment.

Real estate mortgage investment conduits (REMICs) are multi-class securities that qualify for special tax treatment under the Internal Revenue Code. REMICs invest in certain mortgages that are secured principally by interests in real property such as single family homes.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold in public transactions because of Securities and Exchange Commission regulations (these are known as "restricted securities"). Under procedures adopted by the Fund's Board of Trustees, certain restricted securities may be deemed liquid and will not be counted toward this 15% limit.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year to year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although, it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's fiscal years since inception, which run from April 1 to March 31, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which for the year ended March 31, 2005 and the period ended March 31, 2004, have been audited by PricewaterhouseCoopers LLP, independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the periods ended June 30, 2003, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

COLUMBIA INTERMEDIATE BOND FUND

CLASS R SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367."

3. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.


As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the


judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

The Fund

INVESTMENT GOALS

The Fund seeks its total return by pursuing current income and opportunities for capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, including:

. debt securities issued by the U.S. government, including U.S. treasury securities and agency securities (agency securities include certain mortgage-backed securities, which represent interests in pools of mortgages),

. debt securities of corporations, and

. mortgage-backed securities and asset-backed securities issued by private (non-governmental) entities.

The Fund will invest at least 60% of its net assets in high-quality debt securities that are at the time of purchase:

. rated at least A by Standard & Poor's,

. rated at least A by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

The Fund may invest up to 20% of its net assets in lower-rated debt securities. These securities are sometimes referred to as "junk bonds" and are at the time of purchase:

. rated below BBB by Standard & Poor's,

. rated below Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

Normally, the Fund expects to maintain a dollar-weighted average effective maturity of three to ten years.

The Fund seeks to achieve capital appreciation through purchasing bonds that increase in market value.

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics. The advisor may be required to sell portfolio investments to fund redemptions.

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency.


2

The Fund

The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. Such trading usually increases portfolio turnover rates, which usually increases the chance that the Fund will pay investors short-term capital gains (which are taxable at higher rates than long-term capital gains). Such trading may also result in higher brokerage commissions and other transaction costs and additional tax liability, which could reduce the Fund's returns.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payment of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid

The Fund

earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Reinvestment Risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors. Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

The Fund

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

Because Class R shares have not been offered for a full calendar year, the bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's Class A average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers Aggregate Bond Index (Lehman Aggregate Index), a market value-weighted index that tracks fixed-rate, publicly placed, dollar-dominated, and non-convertible investment grade debt issues. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Because the Class R shares have not completed a full calendar year, the bar chart and average annual total returns shown are for Class A shares. Class A shares are not offered in this prospectus. Class R shares would have substantially similar annual returns because they are invested in the same portfolio of securities, and the returns would differ only to the extent that the classes do not have the same expenses and Class R shares do not have a sales charge.
(2) Class A performance information includes returns of the Fund's Class Z shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class Z shares and Class A shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of Class A shares would have been lower. Class A shares were initially offered on July 31, 2000. Class Z shares were initially offered on December 5, 1978. On July 29, 2002, Class S shares were redesignated as Class Z shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not. Higher transaction costs reduce the Fund's returns.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

HOW TO BUY SHARES

All orders for the purchase of Class R shares must be made through your eligible retirement plan.

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all the information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class R shares of the Fund, directly or by exchange. Eligible Investors are as follows:

. 401(k) plans;

. 457 plans;

. Employer-Sponsored 403(b) plans;

. Profit sharing and money purchase pension plans;

. Defined benefit plans; and

Your Account

Additionally, your financial advisor/plan sponsor may receive ongoing 12b-1 fees with respect to Class R shares.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class R.

The Fund also offers four additional classes of shares -- Class A, B and C shares are available through a separate prospectus and Class Z shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on, among other factors, the assets of the plan and the amount invested in the Fund and other Funds distributed by Columbia Management Distributors, Inc. Plan sponsors should consider their eligibility for other classes of shares, including, for some plans, Class Z shares, which are not subject to 12b-1 or shareholder services fees.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class R shares of another fund distributed by Columbia Management Distributors, Inc. that offers Class R shares at net asset value. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

For information about how to sell Class R shares through your eligible retirement plan, please contact your plan administrator. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all of the information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" also means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a money market fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


11

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class R shares and certain services provided to you by your financial advisor. The annual distribution fee may equal up to 0.50%. Distribution fees are paid out of the assets of Class R. Over time, this fee will reduce the return on your investment and may cost you more than paying other types of sales charges.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class R shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.


12

Your Account

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines the net asset value of its Class R shares by dividing total net assets attributable to Class R shares by the number of outstanding Class R shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class R shares.

Dividends, Distributions, and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day
before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.


13

Your Account

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.35% of average daily net assets of the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the


15

Managing the Fund

"NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March, 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the funds or their shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL").

The derivative cases purportedly brought on behalf of the Columbia Funds in the MDL have been consolidated under the lead case. The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, the removal of the trustees of the Columbia Funds, removal of the Columbia Group, disgorgement of all management fees and monetary damages.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.


16

Managing the Fund

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purposes. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described above under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold in public transactions because of Securities and Exchange Commission regulations (these are known as "restricted securities"). Under procedures adopted by the Fund's Board of Trustees, certain restricted securities may be deemed liquid and will not be counted toward this 15% limit.


18

Other Investment Strategies and Risks

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year to year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class R shares of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The chart also assumes that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is presented in the chart, and is net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower.

SUPPLEMENT TO THE PROSPECTUS DATED AUGUST 1, 2005 (THE "PROSPECTUS")
(REPLACING SUPPLEMENTS DATED AUGUST 19, 2005)

COLUMBIA INTERMEDIATE BOND FUND

CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. The name of the Trust on the back cover of the Prospectus in the section titled "For More Information" is revised to read "Columbia Funds Series Trust I."

2. The Investment Company Act file number on the back cover of the Prospectus is revised to read "811-4367".

3. Columbia Funds Distributor, Inc. (the Funds' distributor) and Columbia Funds Services, Inc. (the Funds' transfer agent) changed their names to Columbia Management Distributors, Inc. and Columbia Management Services, Inc., respectively.

4. The following disclosure is added under the heading "PRINCIPAL INVESTMENT STRATEGIES":

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

5. The following disclosure is added under the heading "PRINCIPAL INVESTMENT RISKS":

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors. Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies:
Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the


future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

6. The "CALENDAR YEAR TOTAL RETURNS" and "AVERAGE ANNUAL TOTAL RETURNS" tables for the Fund in the section entitled "PERFORMANCE HISTORY" are updated and restated in their entirety as follows:

7. The section entitled "ELIGIBLE INVESTORS" is revised in its entirety as follows:

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.


IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of a Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (CMD) (i) who holds Class Z shares; (ii) who


held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by CMD;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by CMD;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations, purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Funds reserve the right to change the criteria for eligible investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Funds also reserve the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

8. The section entitled "LEGAL PROCEEDINGS" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.


On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOALS

The Fund seeks its total return by pursuing current income and opportunities for capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds, including:

. debt securities issued by the U.S. government, including U.S. treasury securities and agency securities (agency securities include certain mortgage-backed securities, which represent interests in pools of mortgages),

. debt securities of corporations, and

. mortgage-backed securities and asset-backed securities issued by private (non-governmental) entities.

The Fund will invest at least 60% of its net assets in high-quality debt securities that are at the time of purchase:

. rated at least A by Standard & Poor's,

. rated at least A by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

The Fund may invest up to 20% of its net assets in lower-rated debt securities. These securities are sometimes referred to as "junk bonds" and are at the time of purchase:

. rated below BBB by Standard & Poor's,

. rated below Baa by Moody's Investors Service, Inc.,

. given a comparable rating by another nationally recognized rating agency, or

. unrated securities that the investment advisor believes to be of comparable quality.

Normally, the Fund expects to maintain a dollar-weighted average effective maturity of three to ten years.

The Fund seeks to achieve capital appreciation through purchasing bonds that increase in market value.

The advisor has wide flexibility to vary the allocation among different types of debt securities based on its judgment of which types of securities will outperform the others. In determining whether to buy or sell securities, the advisor evaluates relative values of the various types of securities in which the Fund can invest (e.g., the relative value of corporate debt securities versus mortgage-backed securities under prevailing market conditions), relative values of various rating categories (e.g., relative values of higher-rated securities versus lower-rated securities under prevailing market conditions), and individual issuer characteristics. The advisor may be required to sell portfolio investments to fund redemptions.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's

The Fund

sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security or the entity responsible for payment of a special revenue obligation, changes in general economic conditions, or changes in economic conditions that affect the issuer or the entity responsible for payment of a special revenue obligation may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid

The Fund

earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Reinvestment Risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Fund

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. On July 29, 2002, the Fund's Class S shares were redesignated as Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers Aggregate Bond Index (Lehman Aggregate Index), a market value-weighted index that tracks fixed-rate, publicly placed, dollar-dominated, and non-convertible investment grade debt issues. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions

HOW TO BUY SHARES

When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated price. "Good form" means that the Fund's transfer agent has all the information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with Columbia Funds Services, Inc. or your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

. Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Funds Distributor, Inc.


9

Your Account

(i) who holds Class Z shares; (ii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iii) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Funds Distributor, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Funds Distributor, Inc. ;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary.

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement); or

. Any insurance company, trust company, bank, endowment, investment company or foundation purchasing shares for its own account.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $50 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification number available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all the information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" also means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


12

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations


13

Your Account

are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains, based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer


14

Your Account

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.35% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended March 31, 2005.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see

Managing the Fund

below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC, to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant, who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the Funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the Funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the Funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described above under "The Fund --Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

When-issued securities and forward commitments are securities that are purchased prior to the date they are actually issued or delivered. These securities involve the risk that they may fall in value by the time they are actually issued or that the other party may fail to honor the contract terms.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities are securities that represent ownership interests in large, diversified pools of mortgage loans. Sponsors pool together mortgages of similar rates and terms and offer them as a security to investors.

Most mortgage securities are pooled together and structured as pass-throughs. Monthly payments of principal and interest from the underlying mortgage loans backing the pool are collected by a servicer and "passed through" regularly to the investor. Pass-throughs can have a fixed or an adjustable rate. The majority of pass-through securities are issued by three agencies: Ginnie Mae, Fannie Mae and Freddie Mac. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. A decline in interest rates may lead to a faster rate of repayment on mortgage-backed securities and, therefore, cause the Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of a mortgage-backed security may be difficult to predict and result in greater volatility. During periods of rising interest rates, mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the maturity of the securities.


18

Other Investment Strategies and Risks

Commercial mortgage-backed securities are secured by loans to commercial properties such as office buildings, multi-family apartment buildings, and shopping centers. These loans usually contain prepayment penalties that provide protection from refinancing in a declining interest rate environment.

Real estate mortgage investment conduits (REMICs) are multi-class securities that qualify for special tax treatment under the Internal Revenue Code. REMICs invest in certain mortgages that are secured principally by interests in real property such as single family homes.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment is a security or other position that cannot be disposed of quickly in the normal course of business. For example, some securities are not registered under U.S. securities laws and cannot be sold in public transactions because of Securities and Exchange Commission regulations (these are known as "restricted securities"). Under procedures adopted by the Fund's Board of Trustees, certain restricted securities may be deemed liquid and will not be counted toward this 15% limit.

PORTFOLIO TURNOVER

There are no limits on turnover. Turnover may vary significantly from year to year. The advisor does not expect it to exceed 100% under normal conditions. The Fund generally intends to purchase securities for long-term investment, although it may purchase securities in anticipation of relatively short-term price gains. The Fund will also sell securities without regard to turnover if it believes that developments within specific issuers, sectors or the market as a whole so warrant. Portfolio turnover typically results in transaction costs and produces capital gains or losses resulting in tax consequences for Fund investors. It also increases transaction expenses, which reduce the Fund's total return.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last five fiscal years which run from April 1 to March 31, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which for the year ended March 31, 2005 and the period ended March 31, 2004, have been audited by PricewaterhouseCoopers LLP, independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the years ended June 30, 2003, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm whose report expressed an unqualified opinion on those financial statements and highlights.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratios stay the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

(1) Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A shares were initially offered on October 15, 1991, and Class B and Class C shares were initially offered on March 27, 1995.

5. The footnotes to the table entitled "Shareholder Fees" are revised to provide that the contingent deferred sales charge ("CDSC") applicable to Class A shares applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.

6. The section entitled "Investment Minimums" is revised in its entirety as follows:

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

7. The call-out box entitled "Choosing a Share Class" is revised in its entirety as follows:

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

8. The paragraph immediately following the table entitled "Class A Sales Charges" is revised in its entirety as follows:

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

9. The table entitled "Purchases Over $1 Million" for Class A shares is replaced in its entirety as follows:

PURCHASES OVER $1 MILLION

 AMOUNT PURCHASED                                          COMMISSION %
 Less than $3 million                                          1.00
--------------------------------------------------------------------------------
  $3 million to less than $50 million                          0.50
--------------------------------------------------------------------------------
  $50 million or more                                          0.25

For certain group retirement plans, financial advisors will receive a 1% commission from the distributor on all purchases less than $3 million.

10. The section entitled "Reduced Sales Charges for Larger Investments" is revised in its entirety as follows:

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

-3-

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

o Individual accounts
o Joint accounts
o Certain IRA accounts
o Certain trusts
o UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

-4-

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, though fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

11. All disclosure related to Class B Sales Charges under the section entitled "Sales Charges" is revised in its entirety as follows:

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

CLASS B SALES CHARGES

-----------------------------------------------------------------------------

Commission to financial advisors is 4.00%.
Automatic conversion to Class A shares occurs eight years after purchase.

12. The instructions with respect to redemptions by systematic withdrawal plan in the table under the section "How to Sell Shares" are revised in their entirety as follows:

You may automatically sell a specified dollar amount or percentage of your account on a monthly, quarterly or semi-annual basis and have the proceeds sent to you if your account balance is at least $5,000. The $5,000 minimum account balance requirement has been waived for wrap accounts. This feature is not available if you hold your shares in certificate form. All dividend and capital gains distributions must be reinvested. Be sure to complete the appropriate section of the account application for this feature.

13. The information provided by the bullet point list under the section entitled "FUND POLICY ON TRADING OF FUND SHARES" in the Fund's prospectus is revised and replaced with the following:

A Fund shareholder won't pay an otherwise applicable redemption fee on any of the following transactions:

o shares sold following the death or disability (as defined in the tax code) of the shareholder, including a registered joint owner

o shares sold by or distributions from participant directed retirement plans, such as 401(k), 403(b) 457, Keogh, profit sharing, and money purchase pension accounts, where the Fund does not have access to information about the individual participant account activity, except where the Fund has received an indication that the plan administrator is able to assess the redemption fee to the appropriate accounts (automatic)

o shares sold by certain investment funds, including those that Columbia Management Advisors, LLC or its affiliates may manage (automatic)

o shares sold as part of an automatic rebalancing within an asset allocation program or by certain wrap programs where the program sponsor has provided assurances reasonably satisfactory to the Fund that the program is not designed to be a vehicle for market timing

o shares sold by accounts maintained by a financial institution or intermediary where the Fund has received information reasonably satisfactory to the Fund indicating that the financial institution or intermediary maintaining the account is unable for administrative reasons to assess the redemption fee to underlying shareholders

o shares sold by an account which has demonstrated a hardship, such as a medical emergency, as determined in the absolute discretion of the Fund

o shares that were purchased by reinvested dividends (automatic)

o shares that are redeemed or exchanged through Columbia Funds' Systematic Withdrawal Plan or similar affiliated or unaffiliated automated plans

o the following retirement plan distributions:

o lump-sum or other distributions from a qualified corporate or self-employed retirement plan following retirement (or following attainment of age 59 1/2 in the case of a "key employee" of a "top heavy" plan)

o distributions from an individual retirement account ("IRA") or Custodial Account under Section 403(b)(7) of the tax code, following attainment of age 59 1/2

16. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

-10-

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

INVESTMENT GOAL

The Fund seeks long-term growth by investing primarily in global equities.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. and foreign equity securities. The Fund invests at least 25% of its total assets in the securities of utility companies and may invest up to 75% of the Fund's total assets in U.S. and foreign equity securities and investment-grade debt securities not issued by utility companies. The Fund's investment advisor intends to diversify the Fund's investments among a number of developed countries and market sectors and the Fund will have exposure to at least three countries, including the U.S.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.


UTILITY COMPANIES

Utility companies in which the Fund may invest include companies engaged in the manufacture, production, generation, transmission, sale or distribution of electricity, natural gas or other types of energy, water or other sanitary services. They also include regulated public services such as toll-roads and airports. They also include companies engaged in telecommunications, such as telephone, telegraph, satellite, microwave and other communications media (but excluding companies primarily engaged in public broadcasting, print media, cable television or the Internet). The Fund may invest in companies engaged in the manufacture and production of equipment utilized in the energy and telecommunications industries.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

The Fund

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Utility company securities are subject to special risks. These securities are generally strongly affected by changes in interest rates, as well as by general competitive and market forces in the utilities industries. As interest rates increase, the value of securities of utility companies tends to decrease, and vice versa. In addition, utility companies may be affected by changes in government regulation. In particular, the value of utility company securities may be adversely affected by increased competition resulting from deregulation.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Because the Fund invests predominantly in foreign securities, the Fund may be particularly susceptible to market timers. Market timers generally attempt to take advantage of the way the Fund prices its shares by trading based on market information they expect will lead to a change in the Fund's net asset value on the next pricing day. Market timing activity may be disruptive to Fund management and, since a market timer's profits are effectively paid directly out of the Fund's assets, may negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and discourage frequent trading based on this strategy, it cannot ensure that all such activity can be identified or terminated.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

Average Annual Total Returns are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Morgan Stanley Capital International World Index (MSCI Index), an unmanaged index that tracks the performance of global stocks. The Fund's returns are also compared to the Standard & Poor's Utilities Index (S&P Utilities Index), an unmanaged market capitalization weighted index of natural gas and electric companies. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

The Fund

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to their inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A shares were initially offered on October 15, 1991, and Class B and Class C shares were initially offered on March 27, 1995.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Funds Distributor, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, other administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- Class A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. If your financial advisor does not participate in the Class B discount program, purchases of $250,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

Your Account

Class A shares bought without an initial sales charge in accounts aggregating $1 million to $25 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 18 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $25 million) are subject to a CDSC if redeemed within 18 months of the date of purchase. The 18-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
----------------                    ------------
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $5 million      0.80
------------------------------------------------
$5 million to less than $25 million     0.50
------------------------------------------------
$25 million or more                     0.25

The commission to financial advisors for Class A share purchases of $25 million or more is paid over 12 months but only to the extent the shares remain outstanding.

For Class A share purchases by participants in certain group retirement plans offered through a fee-based program, financial advisors receive a 1.00% commission from the distributor on all purchases of less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.


9

Your Account

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information. Upon request, a Statement of Intent may apply to purchases made 90 days prior to the date the Statement of Intent is received by the Fund.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission. For purposes of obtaining either breakpoint discount, purchases of Galaxy money market funds are not included.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Funds Services, Inc., you will need to provide the foregoing information to a Columbia Funds Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

Purchases of less than $250,000:

                              % deducted when

Automatic conversion to Class A shares occurs eight years after purchase.

You can pay a lower CDSC and reduce the period during which a CDSC would apply when making purchases of Class B shares through a financial advisor that participates in the Class B share discount program for larger purchases as described in the charts below. Some financial advisors are not able to participate because their record keeping or transaction processing systems are not designed to accommodate these reductions. For non-participating financial advisors, purchases of Class B shares must be less than $250,000. Consult your financial advisor to see whether it participates in the discount program for larger purchases. For participating financial advisors, Rights of Accumulation (as described above) apply, so that if the combined value of the eligible Fund accounts in all classes maintained by you and each member of your immediate family (as defined above), together with the value of your current purchase, is at or above a discount level, your current purchase will be subject to a lower CDSC and the applicable reduced holding period, provided that you have notified your financial advisor in writing of the identity of such other accounts and your relationship to the other account holders. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. This Class B share discount program for larger purchases (as further described in the charts below) is not applicable to Class B shares received by former Galaxy Fund Prime B shareholders in connection with the reorganization of the former Galaxy Fund.

If you exchange into a fund participating in the Class B share discount program or transfer your fund account from a financial advisor that does not participate in the program to one that does, the exchanged or transferred shares will retain the pre-existing CDSC but any additional purchases of Class B shares which, together with the exchanged or transferred account, exceed the applicable discount level will be subject to the lower CDSC and the reduced holding period for amounts in excess of the discount level. Your financial advisor will receive the lower commission for purchases in excess of the applicable discount level. If you exchange from a participating fund or transfer your account from a financial advisor that does participate in the program into a non-participating fund or to a financial advisor that does not participate in the program, the exchanged or transferred shares will retain the pre-existing CDSC schedule and holding period but all additional purchases of Class B shares will be subject to the higher CDSC and longer holding period of the non-participating fund or applicable to the non-participating financial advisor.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Shareholders of Columbia Acorn funds that qualify to purchase Class A shares at net asset value may exchange their Class A shares for Class Z shares of another fund distributed by Columbia Funds Distributor, Inc. (see the Statement of Additional Information for a description of these situations). Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


14

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, the Fund imposes a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase, as described below.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

The Fund will assess, subject to limited exceptions, a 2.00% redemption fee on the proceeds of Fund shares that are redeemed (either by selling shares or exchanging into another Columbia Fund) within 60 days of their purchase. The redemption fee is paid to the Fund.

The redemption fee is imposed on Fund shares redeemed (including redemptions by exchange) within 60 days of purchase. In determining which shares are being redeemed, we generally apply a first-in, first-out approach. For Fund shares acquired by exchange, the holding period prior to the exchange will not be considered in determining whether to assess the redemption fee.

The redemption fee will not be imposed if you qualify for a waiver and the Fund has received proper notification, unless the waiver is automatic as noted below. We'll redeem any shares that are eligible for a waiver first.


15

Your Account

A Fund shareholder won't pay an otherwise applicable redemption fee on any of the following transactions:

. shares sold following the death or disability (as defined in the tax code) of the shareholder, including a registered joint owner

. shares sold by or distributions from participant directed retirement plans, such as 401(k), 403(b) 457, Keogh, profit sharing, and money purchase pension accounts, where the Fund does not have access to information about the individual participant account activity, except where the Fund has received an indication that the plan administrator is able to assess the redemption fee to the appropriate accounts (automatic)

. shares sold by certain investment funds, including those that Columbia Management Advisors, Inc. or its affiliates may manage (automatic)

. shares sold as part of an automatic rebalancing within an asset allocation program or by certain wrap programs where the program sponsor has provided assurances reasonably satisfactory to the Fund that the program is not designed to be a vehicle for market timing

. shares sold by accounts maintained by a financial institution or intermediary where the Fund has received information reasonably satisfactory to the Fund indicating that the financial institution or intermediary maintaining the account is unable for administrative reasons to assess the redemption fee to underlying shareholders

. shares sold by an account which has demonstrated a hardship, such as a medical emergency, as determined in the absolute discretion of the Fund

. shares that were purchased by reinvested dividends (automatic)

. the following retirement plan distributions:

. lump-sum or other distributions from a qualified corporate or self-employed retirement plan following retirement (or following attainment of age 59 1/2 in the case of a "key employee" of a "top heavy" plan)

. distributions from an individual retirement account ("IRA") or Custodial Account under Section 403(b)(7) of the tax code, following attainment of age 59 1/2

The Fund also has the discretion to waive the 2.00% redemption fee if the Fund is in jeopardy of failing the 90% income test or losing its RIC qualification for tax purposes.

As described above, certain intermediaries do not assess redemption fees to certain categories of redemptions that do not present significant market timing concerns (such as automatic withdrawal plan redemptions). In these situations, the Fund's ability to assess redemption fees is generally limited by the intermediary's policies and, accordingly, no redemption fees will be assessed on such redemptions.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after a certain number of years, eliminating the distribution fee upon conversion. Conversion may occur three, four or eight years after purchase, depending on the program under which you purchased your shares. See "Your Account -- Sales Charges" for the conversion schedules applicable to Class B shares.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.


18

Your Account

Distribution Options The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. The Fund's investments in foreign securities may be subject to foreign withholding taxes. You may be entitled to claim a credit or deduction with respect to foreign taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other

Managing the Fund

things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the charts and is net of fee waivers or expense reimbursements. Your actual costs may be higher or lower.

SUPPLEMENT TO THE PROSPECTUS DATED AUGUST 1, 2005 (THE "PROSPECTUS")

(REPLACING SUPPLEMENTS DATED AUGUST 19, 2005, SEPTEMBER 26, 2005 AND NOVEMBER 1, 2005)

COLUMBIA U.S. TREASURY INDEX FUND
(THE "FUND")

CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. At a meeting held on September 16, 2005, shareholders of Columbia Large Company Index Fund and Columbia Small Company Index Fund (the "Funds") approved the reorganization of the Funds into Columbia Large Cap Index Fund (formerly named Nations LargeCap Index Fund) and Columbia Small Cap Index Fund (formerly named Nations SmallCap Index Fund), respectively (the "Reorganization"). The Reorganization took place on September 23, 2005. Accordingly, effective September 26, 2005, all references to the Funds in the Prospectus are removed.

2. Effective August 22, 2005, Columbia Funds Distributor, Inc. (the Fund's distributor) and Columbia Funds Services, Inc. (the Fund's transfer agent) changed their names to Columbia Management Distributors, Inc. and Columbia Management Services, Inc., respectively.

3. The "Calendar Year Total Returns" and "Average Annual Total Returns" tables for the Fund in the section entitled "Performance History" are updated and restated in their entirety as follows:

CALENDAR YEAR TOTAL RETURNS

For the periods shown above:


Best quarter: 3rd quarter 2002, +7.25%
Worst quarter: 2nd quarter 2004, -3.27%

(1) The calendar year total returns shown for Class A shares include the returns of the Fund's Class Z shares for periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. Prior to November 25, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II U.S. Treasury Index Fund, the predecessor to the Fund. Class A shares would have had substantially similar annual returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares (in particular, 12b-1 fees, which Class Z shares do not pay) exceed expenses paid by Class Z shares.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class Z shares for periods prior to November 25, 2002, the date on which Class A, B and C shares were initially offered by the Fund. Prior to November 25, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II U.S. Treasury Index Fund, the predecessor to the Fund. The returns have not been adjusted to reflect any differences in expenses (such as 12b-1 fees) between Class Z and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A, B and C shares were initially offered on November 25, 2002, and Trust shares were initially offered on October 1, 1990.

4. The section entitled "Investment Minimums" is revised in its entirety as follows:

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

5. The call-out box entitled "Choosing a Share Class" is revised in its entirety as follows:

CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

6. The table entitled "Class A Sales Charges" is replaced in its entirety as follows:

CLASS A SALES CHARGES

                                             AS a % OF THE                        % OF OFFERING PRICE

7. The section entitled "Reduced Sales Charges for Larger Investments" is revised in its entirety as follows:

A. WHAT ARE THE PRINCIPAL WAYS TO OBTAIN A BREAKPOINT DISCOUNT?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all

-3-

purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. WHAT ACCOUNTS ARE ELIGIBLE FOR BREAKPOINT DISCOUNTS?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. HOW DO I OBTAIN A BREAKPOINT DISCOUNT?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisors' failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. HOW CAN I OBTAIN MORE INFORMATION ABOUT BREAKPOINT DISCOUNTS?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, though fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

8. All disclosure related to Class B Sales Charges under the section entitled "Sales Charges" is revised in its entirety as follows:

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

Purchases of less than $50,000

Commission to financial advisors is 4.00%.

Automatic conversion to Class A shares occurs eight years after purchase.

9. The instructions with respect to redemptions by systematic withdrawal plan in the table under the section "How to Sell Shares" are revised in their entirety as follows:

You may automatically sell a specified dollar amount or percentage of your account on a monthly, quarterly or semi-annual basis and have the proceeds sent to you if your account balance is at least $5,000. The $5,000 minimum account balance requirement has been

-5-

waived for wrap accounts. This feature is not available if you hold your shares in certificate form. All dividend and capital gains distributions must be reinvested. Be sure to complete the appropriate section of the account application for this feature.

10. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the

-6-

"MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

11. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Funds' financial performance. Information is shown for the Funds' fiscal years since inception, which run from April 1 to March 31, unless otherwise indicated. Certain information reflects financial results for a single Fund share. Information for the six-month period ended September 30, 2005 is unaudited. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Funds (assuming reinvestment of all dividends and distributions). This information has been derived from the Funds' financial statements which, for the years ended March 31, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Funds' financial statements, is included in the Funds' annual report. The information for the period ended

-7-

March 31, 2003 has been derived from the Funds' financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Selected data for a share outstanding throughout each period is as follows:

THE FUNDS

INVESTMENT GOAL

Each Fund seeks to provide investment results that, before deduction of operating expenses, match the price and yield performance of its index.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund pursues an indexing strategy to approximate the investment performance of its index. Each Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets plus any borrowings for investment purposes) in the securities included in its index.

The Funds follow INDEXING STRATEGIES and are not actively managed. This means that the Funds' investment advisor does not use economic, financial and market analysis in selecting securities for a Fund. Instead, the advisor attempts to approximate the performance of the Fund's target index by investing the Fund's assets in securities included in that index. The advisor relies on sophisticated computerized tools and analysis in managing the Fund's investments.

The STANDARD & POOR'S 500 INDEX (S&P 500) is an unmanaged index that tracks the performance of 500 widely held, large capitalization U.S. stocks.

The STANDARD & POOR'S SMALLCAP 600 INDEX (S&P SMALLCAP 600) is an unmanaged index that tracks the performance of 600 domestic companies traded on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The S&P SmallCap 600 is heavily weighted with the stocks of small companies.

The CITIGROUP BOND U.S. TREASURY INDEX is an unmanaged index composed of all U.S. Treasury notes and bonds with remaining maturities of at least one year and outstanding principal of at least $25 million that are included in the Citigroup Broad Investment-Grade Bond Index. Securities in the Citigroup Bond U.S. Treasury Index are weighted by market value, that is, the price per bond or note multiplied by the number of bonds or notes outstanding.

The Columbia Large Company Index Fund normally holds all 500 stocks in the S&P 500, in approximately the same percentage as each stock is represented in the S&P 500. From time to time, however, when deemed advisable by the Fund's investment advisor, the Fund may not hold all of the stocks in the S&P 500 or hold the stocks in the same percentages as the index.

The Columbia Small Company Index Fund normally holds all 600 stocks in the S&P SmallCap 600, in approximately the same percentage as each stock is represented in the S&P SmallCap 600. From time to time, however, when deemed advisable by the Fund's investment advisor, the Fund may not hold all of the stocks in the S&P SmallCap 600 or hold the stocks in the same percentages as the index.

To the extent that, from time to time, the stocks in a particular market sector, such as technology, comprise a significant proportion of the S&P 500 or the S&P SmallCap 600, those stocks will be represented in substantially the same proportion in their corresponding funds.

The Columbia Large Company Index Fund and the Columbia Small Company Index Fund


may also invest in stock index futures contracts in order to track the S&P 500 and the S&P SmallCap 600, respectively, when the purchase of individual securities may be less efficient.

The Columbia U.S. Treasury Index Fund will not hold all of the issues in the U.S. Treasury Index because of the costs involved. Instead, the Fund's investment advisor will consider whether or not to include each security in the Fund based on that security's contribution to the Fund's total market value, average coupon rate and average weighted maturity of the Fund as compared to the U.S. Treasury Index.

A Fund will only purchase a portfolio security that is included in its index at the time of purchase. A Fund will normally only buy or sell portfolio securities to adjust to changes in the composition of its index or to accommodate cash flows into and out of the Fund.

Under normal market conditions, it is expected that the quarterly performance of a Fund, before expenses, will track the performance of its index within a .95 correlation coefficient.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily a Fund's normal investment activities. During such times, a Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

In seeking to achieve its investment goal, a Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in each Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent a Fund from achieving its investment goal. You may lose money by investing in a Fund.

Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that a Fund will achieve its investment goal or perform favorably among comparable funds.

Index funds are subject to indexing risk. Your investment in a Fund will typically decline in value when its index declines. Since the Fund is designed to track its index, the Fund cannot purchase other securities that may help offset declines in its index. In addition, because a Fund may not hold all issues included in its index, may not always be fully invested, and bears transaction costs and expenses, a Fund's performance may fail to match the performance of its index, after taking expenses into account.

A Fund may not always be able to track the performance of its index by entering into stock index futures contracts because the prices of stock index futures contracts may not always match the movement of the index to which they relate. Also, a liquid secondary market may not be available, which might prevent the advisor from closing out a futures contract when desired.

The U.S. Treasury Index Fund is subject to interest rate risk, which is the risk of a change in the price of a bond when prevailing interest rates increase


or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Although U.S. Government securities, particularly U.S. Treasury securities, have historically involved little credit risk, if an issuer fails to pay interest or repay principal, the value of your investment could decline.

Since the Columbia Large Company Index Fund and the Columbia Small Company Index Fund purchase equity securities, they are subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Sector risk is inherent in the investment strategy of the Columbia Large Company Index Fund and the Columbia Small Company Index Fund. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although a Fund does not intend to focus on any particular sector, to the extent that the stocks in a particular market sector comprise a significant portion of one of the Fund's indexes and, correspondingly, of a Fund's holdings, the Fund will be especially susceptible to the risks associated with investments in those market sectors.

Small- or mid-cap companies, such as those whose stocks are purchased by the Columbia Small Company Index Fund, may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY (LARGE COMPANY)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

CALENDAR YEAR TOTAL RETURNS (CLASS A)(1)

(BAR CHART)

37.09%   22.54%   32.81%   28.06%   20.49%                                   27.67%   10.16%
                                             -9.08%    -12.22%    -22.05%
 1995     1996     1997     1998     1999     2000       2001       2002      2003     2004

The Class's year-to-date total      For the periods shown in bar chart:
return through June 30, 2005        Best quarter: 4th quarter 1998, +21.24%
was -1.01%.                         Worst quarter: 3rd quarter 2002, -17.03%

(1) The calendar year total returns shown for Class A shares include the returns of the Fund's Class Z shares for periods prior to December 9, 2002, the date on which Class A shares were initially offered by the Fund. Prior to December 9, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II Large Company Index Fund, the predecessor to the Fund. Class A shares would have had substantially similar annual returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares (in particular, 12b-1 fees, which Class Z shares do not pay) exceed expenses paid by Class Z shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class A, Class B and Class C are newer classes of shares. Their performance information includes returns of the Fund's Class Z shares for periods prior to December 9, 2002, the date on which Class A, B and C shares were initially offered by the Fund. Prior to December 9, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II Large Company Index Fund, the predecessor to the Fund. The returns have not been adjusted to reflect any differences in expenses (such as 12b-1 fees) between Class Z and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A, B and C shares were initially offered on December 9, 2002, and Trust shares were initially offered on October 1, 1990.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Funds Distributor, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees, 12b-1 fees, and other expenses that generally include, but are not limited to, trustee and commitment fees. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily


identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

PERFORMANCE HISTORY (SMALL COMPANY)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges.

(1) The calendar year total returns shown for Class A shares include the returns of the Fund's Class Z shares, for periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. Prior to November 25, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II Small Company Index Fund, the predecessor to the Fund. Class A shares would have had substantially similar annual returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class A shares (in particular, 12b-1 fees, which Class Z shares do not pay) exceed expenses paid by Class Z shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Their performance information includes returns of the Fund's Class Z shares for periods prior to November 25, 2002, the date on which Class A, B and C shares were initially offered by the Fund. Prior to November 25, 2002, the Fund's Class Z shares were designated as Trust Shares of the Galaxy II Small Company Index Fund, the predecessor to the Fund. The returns have not been adjusted to reflect any differences in expenses (such as 12b-1 fees) between Class Z and the newer classes of shares. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer classes of shares would have been lower. Class A, B and C shares were initially offered on November 25, 2002, and Trust shares were initially offered on October 1, 1990.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Funds Distributor, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund.

The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When a Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Funds' transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For participants in the Automatic Investment Plan the initial investment minimum is $50. For participants in certain retirement plans the initial investment minimum is $25. The Funds reserve the right to change these investment minimums. Each Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of a Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Funds offer three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. If your financial advisor does not participate in the Class B discount program, purchases of $250,000 or more but less than $1 million can be made only in Class A or Class C shares.


Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Funds also offer an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class B and Class C shares are subject to a CDSC, a sales charge applied at the time you sell your


shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Funds and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, a Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart above, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, a Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Funds and your financial intermediary may not maintain this information. Upon request, a Statement of Intent may apply to purchases made 90 days prior to the date the Statement of Intent is received by a Fund.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law. Eligible accounts include those


registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission. For purposes of obtaining either breakpoint discount, purchases of Galaxy money market funds are not included.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Funds are not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Funds or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Funds' transfer agent, Columbia Funds Services, Inc., you will need to provide the foregoing information to a Columbia Funds Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Funds' Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are made at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

You can pay a lower CDSC and reduce the period during which a CDSC would apply when making purchases of Class B shares through a financial advisor that participates in the Class B share discount program for larger purchases as described in the charts below. Some financial advisors are not able to participate because their record keeping or transaction processing systems are not designed to accommodate these reductions. For non-participating financial advisors, purchases of Class B shares must be less than $250,000. Consult your financial advisor to see whether it participates in the discount program for larger purchases. For participating financial advisors, Rights of Accumulation (as described above) apply, so that if the combined value of the eligible Fund accounts in all classes maintained by you and each member of your immediate family (as defined above), together with the value of your current purchase, is at or above a discount level, your current purchase will be subject to a lower CDSC and the applicable reduced holding period, provided that you have notified your financial advisor in writing of the identity of such other accounts and your relationship to the other account holders. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Funds are not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Funds or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. This Class B share discount program for larger purchases (as further described in the charts below) is not applicable to Class B shares received by former Galaxy Fund Prime B shareholders in connection with the reorganization of the former Galaxy Fund.

If you exchange into a fund participating in the Class B share discount program or transfer your fund account from a financial advisor that does not participate in the program to one that does, the exchanged or transferred shares will retain the pre-existing CDSC but any additional purchases of Class B shares which, together with the exchanged or transferred account, exceed the applicable discount level will be subject to the lower CDSC and the reduced holding period for amounts in excess of the discount level. Your financial advisor will receive the lower commission for purchases in excess of the applicable discount level. If you exchange from a participating fund or transfer your account from a financial advisor that does participate in the program into a non-participating fund or to a financial advisor that does not participate in the program, the exchanged or transferred shares will retain the pre-existing CDSC schedule and holding period but all additional purchases of Class B shares will be subject to the higher CDSC and longer holding period of the non-participating fund or applicable to the non-participating financial advisor.

CLASS C SHARES Your purchases of Class C shares are made at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same class (and in some cases, certain other classes) of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES


Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Funds' shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if a Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an


exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically are not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Funds' practices discussed above.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither a Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN Each Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B, and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Treasury Fund's Class C share distribution fee so that it does not exceed 0.60% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after a certain number of years, eliminating the distribution fee upon conversion. Conversion may occur three, four or eight years after purchase, depending on the program under which you purchased your shares. See "Your Account -- Sales Charges" for the conversion schedule applicable to Class B shares.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the


services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of a Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUNDS' SHARE PRICE IS DETERMINED The price of each class of a Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

Each Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, each Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Funds may use other data to determine the fair value of the securities.

Each Fund, with the exception of Columbia U.S. Treasury Index Fund, has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.


You can find the daily prices of some share classes for each Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Funds' transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Funds.

DIVIDENDS, DISTRIBUTIONS AND TAXES Each Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Funds, net of expenses incurred by the Funds.

Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net
                       short-term capital gains, which are gains on sales of
                       securities held for a 12-month period or less.

UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Large Company and Small Company Funds distribute any dividends annually and any capital gains (including short-term capital gains) at least annually. The Treasury Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares of the Treasury Fund begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, each Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your current fund

Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest


capital gains

Receive all distributions in cash (with one of the following options):

- send the check to your address of record

- send the check to a third party address

- transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUNDS

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov.


A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Funds, including investment advisory fees and other Fund costs, on the Funds' returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Funds assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Funds, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

4. The section entitled "Eligible Investors" is revised in its entirety as follows:

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

-2-

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of a Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 minimum initial investment

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (CMD) (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by CMD;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by CMD;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

-3-

The Funds reserve the right to change the criteria for eligible investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Funds also reserve the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

5. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUNDS

INVESTMENT GOAL

Each Fund seeks to provide investment results that, before deduction of operating expenses, match the price and yield performance of its index.

PRINCIPAL INVESTMENT STRATEGIES

Each Fund pursues an indexing strategy to approximate the investment performance of its index. Each Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets plus any borrowings for investment purposes) in the securities included in its index.

The Funds follow INDEXING STRATEGIES and are not actively managed. This means that the Funds' investment advisor does not use economic, financial and market analysis in selecting securities for a Fund. Instead, the advisor attempts to approximate the performance of the Fund's target index by investing the Fund's assets in securities included in that index. The advisor relies on sophisticated computerized tools and analysis in managing the Fund's investments.

The STANDARD & POOR'S 500 INDEX (S&P 500) is an unmanaged index that tracks the performance of 500 widely held, large capitalization U.S. stocks.

The STANDARD & POOR'S SMALLCAP 600 INDEX (S&P SMALLCAP 600) is an unmanaged index that tracks the performance of 600 domestic companies traded on the New York Stock Exchange, the American Stock Exchange and NASDAQ. The S&P SmallCap 600 is heavily weighted with the stocks of small companies.

The CITIGROUP BOND U.S. TREASURY INDEX is an unmanaged index composed of all U.S. Treasury notes and bonds with remaining maturities of at least one year and outstanding principal of at least $25 million that are included in the Citigroup Broad Investment-Grade Bond Index. Securities in the Citigroup Bond U.S. Treasury Index are weighted by market value, that is, the price per bond or note multiplied by the number of bonds or notes outstanding.

The Columbia Large Company Index Fund normally holds all 500 stocks in the S&P 500, in approximately the same percentage as each stock is represented in the S&P 500. From time to time, however, when deemed advisable by the Fund's investment advisor, the Fund may not hold all of the stocks in the S&P 500 or hold the stocks in the same percentages as the index.

The Columbia Small Company Index Fund normally holds all 600 stocks in the S&P SmallCap 600, in approximately the same percentage as each stock is represented in the S&P SmallCap 600. From time to time, however, when deemed advisable by the Fund's investment advisor, the Fund may not hold all of the stocks in the S&P SmallCap 600 or hold the stocks in the same percentages as the index.

To the extent that, from time to time, the stocks in a particular market sector, such as technology, comprise a significant proportion of the S&P 500 or the S&P SmallCap 600, those stocks will be represented in substantially the same proportion in their corresponding funds.

The Columbia Large Company Index Fund and the Columbia Small Company Index Fund


may also invest in stock index futures contracts in order to track the S&P 500 and the S&P SmallCap 600, respectively, when the purchase of individual securities may be less efficient.

The Columbia U.S. Treasury Index Fund will not hold all of the issues in the U.S. Treasury Index because of the costs involved. Instead, the Fund's investment advisor will consider whether or not to include each security in the Fund based on that security's contribution to the Fund's total market value, average coupon rate and average weighted maturity of the Fund as compared to the U.S. Treasury Index.

A Fund will only purchase a portfolio security that is included in its index at the time of purchase. A Fund will normally only buy or sell portfolio securities to adjust to changes in the composition of its index or to accommodate cash flows into and out of the Fund.

Under normal market conditions, it is expected that the quarterly performance of a Fund, before expenses, will track the performance of its index within a .95 correlation coefficient.

At times, the advisor may determine that adverse market conditions make it desirable to suspend temporarily a Fund's normal investment activities. During such times, a Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent a Fund from achieving its investment goal.

In seeking to achieve its investment goal, a Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in each Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by a Fund's shareholders is not required to modify or change a Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Funds are described below. There are many circumstances (including additional risks that are not described here) which could prevent a Fund from achieving its investment goal. You may lose money by investing in a Fund.

Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that a Fund will achieve its investment goal or perform favorably among comparable funds.

Index funds are subject to indexing risk. Your investment in a Fund will typically decline in value when its index declines. Since the Fund is designed to track its index, the Fund cannot purchase other securities that may help offset declines in its index. In addition, because a Fund may not hold all issues included in its index, may not always be fully invested, and bears transaction costs and expenses, a Fund's performance may fail to match the performance of its index, after taking expenses into account.

A Fund may not always be able to track the performance of its index by entering into stock index futures contracts because the prices of stock index futures contracts may not always match the movement of the index to which they relate. Also, a liquid secondary market may not be available, which might prevent the advisor from closing out a futures contract when desired.


The U.S. Treasury Index Fund is subject to interest rate risk, which is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Although U.S. Government securities, particularly U.S. Treasury securities, have historically involved little credit risk, if an issuer fails to pay interest or repay principal, the value of your investment could decline.

Since the Columbia Large Company Index Fund and the Columbia Small Company Index Fund purchase equity securities, they are subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Sector risk is inherent in the investment strategy of the Columbia Large Company Index Fund and the Columbia Small Company Index Fund. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although a Fund does not intend to focus on any particular sector, to the extent that the stocks in a particular market sector comprise a significant portion of one of the Fund's indexes and, correspondingly, of a Fund's holdings, the Fund will be especially susceptible to the risks associated with investments in those market sectors.

Small- or mid-cap companies, such as those whose stocks are purchased by the Columbia Small Company Index Fund, may be more susceptible to market downturns, and their prices could be more volatile. These companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team and may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, such companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY (LARGE COMPANY)

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.(1)

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Funds, directly or by exchange. Class Z shares of the Funds generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by a Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or


- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Funds Distributor, Inc. (i) who holds Class Z shares; (ii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iii) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Funds Distributor, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Funds Distributor, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary.

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Funds for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Funds' transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement); or

- Any insurance company, trust company, bank, endowment, investment company or foundation purchasing shares for its own account.

The Funds reserve the right to change the criteria for Eligible Investors and the investment minimums. No minimum Investment applies to accounts participating in the automatic investment plan; however, each investment requires a $50 minimum purchase. The Funds also reserve the right to refuse a purchase order for any reason, including if they believe that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Funds offer one class of shares in this prospectus -- CLASS Z.

The Funds also offer three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing


to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Funds Distributor, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. A Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Funds' policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of a Fund on any regular business day that the NYSE is open.

When a Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Funds' transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

A Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, a Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Funds' long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Funds. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Funds has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

Each Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if a Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future


purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if a Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), each Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Funds are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into a Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Funds typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Funds seek to act in a manner that they believe is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither a Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such


factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of a Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Funds' investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Funds. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUNDS' SHARE PRICE IS DETERMINED The price of a Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

Each Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, a Fund must determine the price of each security in its portfolio at the close of each trading day. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, a Fund may use other data to determine the fair value of the securities.

Each Fund, with the exception of the Columbia U.S. Treasury Index Fund, has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for each Fund in most major


daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Funds' transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Funds.

DIVIDENDS, DISTRIBUTIONS AND TAXES Each Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends       Represents interest and dividends earned from securities
                held by the Funds, net of expenses incurred by the Funds.

Capital gains   Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.

UNDERSTANDING FUND DISTRIBUTIONS

Each Fund may earn income from the securities it holds. Each Fund also may realize capital gains or losses on sales of its securities. Each Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of a Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Large Company and Small Company Funds distribute any dividends annually and any capital gains (including short-term capital gains) at least annually. The Treasury Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares of the Treasury Fund begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, each Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your current fund

Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains


Receive all distributions in cash (with one of the following options):

- send the check to your address of record

- send the check to a third party address

- transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in a Fund may have additional personal tax implications. Please consult your tax advisor about federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by each Fund, you may realize a capital gain or loss when selling or exchanging shares of a Fund. Such transactions also may be subject to federal, state and local income tax.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Funds Distributor, Inc. ("CFD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CFD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Funds' Class Z financial performance.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Funds, including investment advisory fees and other Fund costs, on the Funds' returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z Shares of the Funds assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Funds, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED SEPTEMBER 1, 2005 (THE "PROSPECTUS")
(REPLACING SUPPLEMENTS DATED OCTOBER 5, 2005 AND OCTOBER 21, 2005)

COLUMBIA CORE BOND FUND
(FORMERLY NAMED COLUMBIA QUALITY PLUS BOND FUND)

(THE "FUND")

CLASS A, B AND C SHARES

The Prospectus is hereby supplemented with the following information:

1. Effective October 10, 2005, Columbia Quality Plus Bond Fund changed its name to Columbia Core Bond Fund; accordingly, all references throughout the Prospectus are changed as appropriate.

2. The section under the heading "PRINCIPAL INVESTMENT STRATEGIES" is revised and replaced in its entirety with the following disclosure:

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P), Moody's Investors Service, Inc. (Moody's) or Fitch, Inc. (Fitch), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by S&P, Moody's or Fitch (or unrated

but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

3. The following disclosure is added under the heading "PRINCIPAL INVESTMENT RISKS":

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

4. The second paragraph under the heading "AVERAGE ANNUAL TOTAL RETURNS" in the call-out box entitled "Understanding Performance" is revised in its entirety as follows:

Beginning in 2005, the Fund's benchmark was changed to the Lehman Brothers Aggregate Bond Index (the Lehman Aggregate Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Previously, the Fund's returns were compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. The advisor believes that the Lehman Aggregate Index, because of its greater emphasis on total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Lehman Aggregate Index, as well as the Fund's previous benchmark, the Lehman Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The calendar year total returns shown for Class A shares include the returns of Prime A Shares of Galaxy Quality Plus Bond Fund, the predecessor to the Fund, for periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. The returns shown for Class A shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund for periods prior to the inception of Prime A Shares (November 1, 1998). Class A shares generally would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A shares (in particular, 12b-1 fees, which Class T shares do not pay) exceed expenses paid by Retail A Shares.

by the Fund. The returns shown for Class A shares and Class B shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund (adjusted, as necessary, to reflect the sales charges applicable to Class shares and Class B shares, respectively) for periods prior to the inception of Prime A Shares and Prime B Shares (November 1, 1998). Class A and Class B shares would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although returns would be lower to the extent that expenses for Class A and Class B shares exceed expenses for Retail A Shares. The returns shown for Class C shares for periods prior to November 25, 2002 include the returns of Retail B Shares of Galaxy Quality Plus Bond Fund (adjusted to reflect the sales charge applicable to Class C shares). The returns shown for Class C shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to the date of inception of Retail B Shares (March 4, 1996). Class C shares would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class C shares exceed expenses paid by Retail A and Retail B Shares.

6. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and

-4-

has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

7. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class A and Class B shares prior to November 25, 2002, the date Class A and Class B shares were initially offered, is for the former Prime A shares and Prime B shares, respectively, of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended October 31, 2005 is unaudited. Other information has been derived from the Fund's financial statements which, for the years ended April 30, 2004 and 2005, have been audited by Pricewaterhouse Coopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

COLUMBIA CORE BOND FUND
(THE "FUND")

SUPPLEMENT TO THE PROSPECTUSES DATED SEPTEMBER 1, 2005 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares and Class G shares convert to Class A shares and Class T shares after eight years, respectively. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of current income consistent with prudent risk of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. The Fund expects that under normal circumstances at least 50% of its net assets plus any borrowings for investment purposes will be invested in high quality debt obligations that have one of the top two ratings assigned by S&P or Moody's or unrated securities determined by the advisor to be of comparable quality. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by either S&P or Moody's (or unrated but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

THE FUND

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.


3

THE FUND

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

THE FUND


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

CALENDAR YEAR TOTAL RETURNS (CLASS A)(1)

21.20%      1.37%      9.11%      9.24%                12.57%      7.30%     10.28%      3.33%      3.45%

The Class's year-to-date total return         For the periods shown in bar chart:
through June 30, 2005 was +2.40%.             Best quarter: 2nd quarter 1995, +7.54%
                                              Worst quarter: 2nd quarter 2004, -2.90%

(1) The calendar year total returns shown for Class A shares include the returns of Prime A Shares of Galaxy Quality Plus Bond Fund, the predecessor to the Fund, for periods prior to November 25, 2002, the date on which Class A shares were initially offered by the Fund. The returns shown for Class A shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund for periods prior to the inception of Prime A Shares (November 1, 1998). Class A shares generally would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would be lower to the extent that expenses for Class A shares (in particular, 12b-1 fees, which Class T shares do not pay) exceed expenses paid by Retail A Shares.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Prime A Shares (for Class A shares) and Prime B Shares (for Class B shares) of Galaxy Quality Plus Bond Fund for periods prior to November 25, 2002, the date on which Class A, Class B and Class C shares were initially offered by the Fund. The returns shown for Class A shares and Class B shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund (adjusted, as necessary, to reflect the sales charges applicable to Class A shares and Class B shares, respectively) for periods prior to the inception of Prime A Shares and Prime B Shares (November 1, 1998). Class A and Class B shares would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although returns would be lower to the extent that expenses for Class A and Class B shares exceed expenses for Retail A Shares. The returns shown for Class C shares for periods prior to November 25, 2002 include the returns of Retail B Shares of Galaxy Quality Plus Bond Fund (adjusted to reflect the sales charge applicable to Class C shares). The returns shown for Class C shares also include the returns of Retail A Shares of Galaxy Quality Plus Bond Fund (adjusted to reflect the sales charges applicable to Class C shares) for periods prior to the date of inception of Retail B Shares (March 4, 1996). Class C shares would have had substantially similar returns because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class C shares exceed expenses paid by Retail A and Retail B Shares.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees, 12b-1 fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years.

If this waiver were reflected in the table, the 12b-1 fees for Class C shares would be 0.85% and the total annual fund operating expenses for Class C shares would be 1.51%. This arrangement may be modified or terminated by the distributor at any time.

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account.

YOUR ACCOUNT

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B AND C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 or more but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers three additional classes of shares, Class T, G and Z shares, exclusively to certain institutional and other investors. Class T, G and Z shares are made available through separate prospectuses provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on

the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

For certain group retirement plans, financial advisors will receive a 1% commission from the distributor on all purchases of less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to


11

YOUR ACCOUNT

that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the

selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


15

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Fund's Class C share distribution fee so that it does not exceed 0.60% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.


16

YOUR ACCOUNT

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not


17

YOUR ACCOUNT

be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

("CMD") (collectively, "the Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds'

MANAGING THE FUND

management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

DERIVATIVE STRATEGIES

The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts and inverse floaters, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund, or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class A and Class B shares prior to November 25, 2002, the date Class A and Class B shares were initially offered, is for the former Prime A shares and Prime B shares, respectively, of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the years ended April 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights.

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

COLUMBIA CORE BOND FUND
(FORMERLY NAMED COLUMBIA QUALITY PLUS BOND FUND)

(THE "FUND")

CLASS T AND G SHARES

The Prospectus is hereby supplemented with the following information:

1. Effective October 10, 2005, Columbia Quality Plus Bond Fund changed its name to Columbia Core Bond Fund; accordingly, all references throughout the Prospectus are changed as appropriate.

2. The section under the heading "PRINCIPAL INVESTMENT STRATEGIES" is revised and replaced in its entirety with the following disclosure:

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P), Moody's Investors Service, Inc. (Moody's) or Fitch, Inc. (Fitch), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by S&P, Moody's or Fitch (or unrated

-1-

but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

3. The following disclosure is added under the heading "PRINCIPAL INVESTMENT RISKS":

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

4. The second paragraph under the heading "AVERAGE ANNUAL TOTAL RETURNS" in the call-out box entitled "Understanding Performance" is revised in its entirety as follows:

Beginning in 2005, the Fund's benchmark was changed to the Lehman Brothers Aggregate Bond Index (the Lehman Aggregate Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Previously, the Fund's returns were compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. The advisor believes that the Lehman Aggregate Index, because of its greater emphasis on total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Lehman Aggregate Index, as well as the Fund's previous benchmark, the Lehman Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G Shares) of Galaxy Quality Plus Bond Fund for periods prior to November 25, 2002, the date on which Class T and G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares) for periods prior to the inception of Retail B Shares of Galaxy Quality Plus Bond Fund (March 4, 1996). Retail A Shares of Galaxy Quality Plus Bond Fund were initially offered on December 14, 1990. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

6. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the

-4-

Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

7. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class T and Class G shares prior to November 25, 2002, the date Class T and Class G shares were initially offered, is for the former Retail A shares and Retail B shares, respectively, of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended October 31, 2005 is unaudited. Other information has been derived from the Fund's financial statements which, for the years ended April 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another

independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of current income consistent with prudent risk of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. The Fund expects that under normal circumstances at least 50% of its net assets plus any borrowings for investment purposes will be invested in high quality debt obligations that have one of the top two ratings assigned by S&P or Moody's or unrated securities determined by the advisor to be of comparable quality. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by either S&P or Moody's (or unrated but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

THE FUND

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.


3

THE FUND

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class T shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class T and G shares, including sales charges, compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

THE FUND


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class T share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class G share returns do not reflect Class T share returns after conversion of Class G shares to Class T shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) The average annual total returns shown include the returns of Retail A Shares (for Class T shares) and Retail B Shares (for Class G Shares) of Galaxy Quality Plus Bond Fund for periods prior to November 25, 2002, the date on which Class T and G shares were initially offered by the Fund. The returns shown for Class G shares also include the returns of Retail A Shares (adjusted to reflect the sales charges applicable to Class G shares) for periods prior to the inception of Retail B Shares of Galaxy Quality Plus Bond Fund (March 4, 1996). Retail A Shares of Galaxy Quality Plus Bond Fund were initially offered on December 14, 1990. Class G shares generally would have had substantially similar returns to Retail A Shares because they would have been invested in the same portfolio of securities, although the returns would have been lower to the extent that expenses for Class G shares exceed expenses paid by Retail A Shares.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees, 12b-1 fees, shareholder service fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class G shares convert to Class T shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

YOUR ACCOUNT

CLASS T AND G SHARES ARE SOLD ONLY TO INVESTORS WHO RECEIVED (AND WHO HAVE CONTINUOUSLY HELD) CLASS T OR G SHARES IN CONNECTION WITH THE MERGER OF CERTAIN GALAXY FUNDS INTO VARIOUS COLUMBIA FUNDS (FORMERLY NAMED LIBERTY FUNDS).

Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CLASS T SHARES Your purchases of Class T shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class T shares. The amount of the sales charge differs depending on the amount you invest as shown in the tables below.

For certain group retirement plans, financial advisors will receive a 1% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class T and G shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class T shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT You also may pay a lower sales charge when purchasing Class T shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.


11

YOUR ACCOUNT

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, though fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS G SHARES Your purchases of Class G shares are made at Class G's net asset value. Class G shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class G shares as described in the chart below.

Automatic conversion to Class T shares occurs eight years after purchase.

Please see the Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B Shares of the former Galaxy Fund purchased or acquired prior to January 1, 2001.

HOW TO EXCHANGE SHARES

You may exchange your Class T shares for Class A or Class T shares, and may exchange your Class G shares for Class B or Class G shares, of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Class A or Class B shares acquired upon exchange of Class T and Class G shares may not be further exchanged back into Class T or Class G shares unless you continue to hold Class T or Class G shares. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange


15

YOUR ACCOUNT

purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class G shares and certain services provided to you by your financial advisor. The annual fee for shareholder liaison services and administration support may equal up to 0.50% for Class G shares. The annual distribution fee may equal up to 0.65% for Class G shares. The Fund does not intend to pay more than a total of 0.80% for Class G shares in distribution and shareholder service fees during the current fiscal year. The Fund has also adopted a plan that permits it to pay for certain services provided to Class T shareholders by their financial advisors. The annual service fee may equal up to 0.50% for Class T shares. The Fund does not intend to pay more than 0.15% for Class T shares in shareholder service fees during the current fiscal year. The foregoing fees are paid out of the assets of the relevant class. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges.


16

YOUR ACCOUNT

Class G shares automatically convert to Class T shares after eight years, eliminating a portion of these fees upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price


17

YOUR ACCOUNT

of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, Inc. "Columbia Management", located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Management is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Management runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Management is a direct wholly owned subsidiary of Columbia Management Group, LLC, ("CMG") which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Management, a registered investment advisor, has been an investment advisor since 1969.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.49% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended April 30, 2005.

PORTFOLIO MANAGER

MARIE M. SCHOFIELD, a senior vice president of Columbia Management, is the manager for the Fund and has managed the Fund since it commenced operations in November, 2002. Ms. Schofield managed the Galaxy Quality Plus Bond Fund, the predecessor to the Fund, since February, 1996. Ms. Schofield has been associated with Columbia Management or its predecessors since February, 1990.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) ("CMD") (collectively, "the Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements." The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds'


20

MANAGING THE FUND

management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

DERIVATIVE STRATEGIES

The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts and inverse floaters, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class T and Class G shares prior to November 25, 2002, the date Class T and Class G shares were initially offered, is for the former Retail A shares and Retail B shares, respectively, of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the years ended April 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class G shares convert to Class T shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

COLUMBIA FUNDS SERIES TRUST I
(THE "TRUST")

SUPPLEMENT TO THE PROSPECTUS DATED SEPTEMBER 1, 2005 (THE
"PROSPECTUS") (REPLACING SUPPLEMENTS DATED OCTOBER 5,
2005 AND OCTOBER 21, 2005)

COLUMBIA CORE BOND FUND
(FORMERLY NAMED COLUMBIA QUALITY PLUS BOND FUND)

(THE "FUND")

CLASS Z SHARES

The Prospectus is hereby supplemented with the following information:

1. Effective October 10, 2005, Columbia Quality Plus Bond Fund changed its name to Columbia Core Bond Fund; accordingly, all references throughout the Prospectus are changed as appropriate.

2. The section under the heading "PRINCIPAL INVESTMENT STRATEGIES" is revised and replaced in its entirety with the following disclosure:

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may participate in mortgage dollar rolls and may roll all, a portion, or none of the Fund's mortgage positions.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P), Moody's Investors Service, Inc. (Moody's) or Fitch, Inc. (Fitch), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by S&P, Moody's or Fitch (or unrated

-1-

but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

3. The following disclosure is added under the heading "PRINCIPAL INVESTMENT RISKS":

Mortgage dollar rolls are transactions in which the Fund sells mortgage-backed securities to a dealer and simultaneously agrees to purchase similar securities in the future at a predetermined price. These transactions simulate an investment in mortgage-backed securities and have the potential to enhance the Fund's returns and reduce its administrative burdens, compared with holding mortgage-backed securities directly. Mortgage dollar rolls involve the risks that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the other party may default on its obligations. These transactions may increase the Fund's portfolio turnover rate.

4. The second paragraph under the heading "AVERAGE ANNUAL TOTAL RETURNS" in the call-out box entitled "Understanding Performance" is revised in its entirety as follows:

Beginning in 2005, the Fund's benchmark was changed to the Lehman Brothers Aggregate Bond Index (the Lehman Aggregate Index), an unmanaged market value-weighted index that tracks the daily price, coupon, pay-downs, and total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues with at least $250 million par amount outstanding and with at least one year to final maturity. Previously, the Fund's returns were compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. The advisor believes that the Lehman Aggregate Index, because of its greater emphasis on total return performance of fixed-rate, publicly placed, dollar-denominated, and non-convertible investment grade debt issues, more accurately reflects the type of securities in which the Fund invests. The Fund's average annual returns for the one-year, five-year and ten-year periods are shown compared to the Lehman Aggregate Index, as well as the Fund's previous benchmark, the Lehman Index. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

5. The "Calendar Year Total Returns" and "Average Annual Total Returns" tables for the Fund in the section entitled "Performance History" are updated and restated in their entirety as follows:

6. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as

-3-

outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's

-4-

memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

7. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class Z shares prior to November 25, 2002, the date Class Z shares were initially offered, is for the former Trust shares of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended October 31, 2005 is unaudited. Other information has been derived from the Fund's financial statements which, for the fiscal years ended April 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002 and 2001 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

THE FUND

INVESTMENT GOAL

The Fund seeks a high level of current income consistent with prudent risk of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as in U.S. and foreign corporate debt obligations, such as notes and bonds. The Fund also invests in asset-backed and mortgage-backed securities and in money market instruments, such as commercial paper and obligations of U.S. and foreign banks.

The Fund may from time to time invest in a limited amount of interest rate futures contracts. The Fund will use interest rate futures contracts, which may be considered derivatives, in an effort to manage the impact to the Fund of changes in interest rates.

In selecting portfolio securities for the Fund, the Fund's investment advisor monitors and evaluates economic trends. It establishes duration targets and ranges of interest rates on bonds of various maturities, and determines the appropriate allocation of the Fund's investments among various market sectors.

Substantially all of the Fund's investments (under normal circumstances, at least 80% of the Fund's net assets plus any borrowings for investment purposes) will be debt obligations of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's Ratings Group (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. High quality securities tend to pay less income than lower-rated securities. The Fund expects that under normal circumstances at least 50% of its net assets plus any borrowings for investment purposes will be invested in high quality debt obligations that have one of the top two ratings assigned by S&P or Moody's or unrated securities determined by the advisor to be of comparable quality. Occasionally, the rating of a security held by the Fund may be downgraded to below investment grade. If that happens, the Fund does not have to sell the security unless the advisor determines that under the circumstances the security is no longer an appropriate investment for the Fund. However, the Fund will sell promptly any debt securities that are not rated investment grade by either S&P or Moody's (or unrated but determined by the advisor to be of comparable quality) to the extent such securities exceed 5% of the Fund's net assets.

The Fund's average weighted maturity will vary from time to time depending on current market and economic conditions and the advisor's assessment of probable changes in interest rates.

The Fund will sell a portfolio security when, as a result of changes in the economy or the performance of the security or other circumstances, the advisor believes that holding the security is no longer consistent with the Fund's investment goal.

As part of its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional tax liability.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

THE FUND

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, municipal bonds and mortgage-backed and asset-backed securities, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income. The Fund's investments in securities issued by U.S. government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association, are not funded by Congressional appropriations and are neither guaranteed nor insured by the U.S. government. Furthermore, no assurances can be given that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

Structure risk is the risk that an event will occur (such as a security being prepaid or called) that alters the security's cash flows. Prepayment risk is a particular type of structure risk that is associated with investments in asset-backed and mortgage-backed securities. With respect to investments in mortgage-backed securities, prepayment risk is the possibility that, as prevailing interest rates fall, homeowners are more likely to refinance their home mortgages. When mortgages are refinanced, the principal on mortgage-backed securities is paid earlier than expected. In an environment of declining interest rates, asset-backed and mortgage-backed securities may offer less potential for gain than other debt securities. During periods of rising interest rates, asset-backed and mortgage-backed securities have a high risk of declining in price because the declining prepayment rates effectively increase the expected life of the security. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an


3

THE FUND

exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Frequent trading risk. Frequent trading of investments usually increases the chance that the Fund will pay investors short-term capital gains. These gains are taxable at higher rates than long-term capital gains. Frequent trading could also mean higher transaction costs, which could reduce the Fund's return.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of a broad measure of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

THE FUND


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses.(1)

The Fund's returns are compared to the Lehman Brothers Government/Credit Bond Index (the Lehman Index), an unmanaged index that tracks the performance of U.S. Government and corporate bonds rated investment grade or better, with maturities of at least one year. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management and administration fees and other expenses that generally include, but are not limited to, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts (IRAs)), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

YOUR ACCOUNT

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of another fund distributed by Columbia Management Distributors, Inc. (CMD) (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by CMD;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by CMD;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary.

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations, purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

YOUR ACCOUNT

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers five additional classes of shares -- Class A, B, C, T and G shares are available through separate prospectuses. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):

  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.


15

YOUR ACCOUNT

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, Inc. ("Columbia Management"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Management is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Management runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Management is a direct wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Management, a registered investment advisor, has been an investment advisor since 1969.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including administration, pricing and bookkeeping, and other fees paid to Columbia Management by the Fund, amounted to 0.49% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended April 30, 2005.

PORTFOLIO MANAGER

MARIE M. SCHOFIELD, a senior vice president of Columbia Management, is the manager for the Fund and has managed the Fund since it commenced operations in November, 2002. Ms. Schofield managed the Galaxy Quality Plus Bond Fund, the predecessor to the Fund, since February, 1996. Ms. Schofield has been associated with Columbia Management or its predecessors since February, 1990.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds


17

MANAGING THE FUND

management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

OTHER INVESTMENT STRATEGIES AND RISKS

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goal. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or any of its investment strategies.

DERIVATIVE STRATEGIES

The Fund may enter into a number of derivative strategies, including those that employ futures and options, swap contracts and inverse floaters, to gain or reduce exposure to particular securities or markets. These strategies, commonly referred to as derivatives, involve the use of financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use these strategies to adjust for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an interest in an opposite position. Derivative strategies involve the risk that they may exaggerate a loss, potentially losing more money than the actual cost of the underlying security, or limit a potential gain. Also, with some derivative strategies there is the risk that the other party to the transaction may fail to honor its contract terms, causing a loss to the Fund or that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the last five fiscal years, which run from May 1 to April 30, unless otherwise indicated. Information for Class Z shares prior to November 25, 2002, the date Class Z shares were initially offered, is for the former Trust shares of the Galaxy Quality Plus Bond Fund. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which, for the fiscal years ended April 30, 2004 and 2005, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. The information for the six months ended April 30, 2003 and the fiscal years ended October 31, 2002, 2001 and 2000 has been derived from the Fund's financial statements which have been audited by another independent registered public accounting firm, whose report expressed an unqualified opinion on those financial statements and highlights. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

Class A shares were initially offered on October 21, 1971, Class B shares were initially offered on June 8, 1992, and Class C shares were initially offered on January 15, 1996.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

-2-

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and

-3-

ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from June 1 to May 31, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended November 30, 2005 is unaudited. Other information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Selected data for a share outstanding throughout each period is as follows:

(a) The Fund changed its fiscal year end from December 31 to May 31.

(b) Per share data was calculated using average shares outstanding during the period.

(c) Effective January 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and accreting discount on all debt securities. The effect of this change for the year ended December 31, 2001 was to increase net investment income per share by $0.05, decrease net realized and unrealized loss per share by $0.05 and increase the ratio of net investment income to average net assets from 9.76% to 10.34%. Per share data and ratios for periods prior to December 31, 2001 have not been restated to reflect this change in presentation.

(d) The per share net investment income amount does not reflect the period's

-4-

reclassification of differences between book and tax basis net investment income.

(e) Total return at net asset value assuming all distributions reinvested and no initial sales charge or contingent deferred sales charge.

(f) Not annualized.

(g) Had the Investment Advisor and/or Transfer Agent not waived a portion of expenses, total return would have been reduced.

(h) Total return includes a voluntary reimbursement by the Investment Advisor for a realized investment loss. This reimbursement had an impact of less than 0.01% on the Fund's total return.

(i) The benefits derived from custody credits had an impact of less than 0.01%.

(EACH A "FUND" AND COLLECTIVELY, THE "FUNDS")

SUPPLEMENT TO THE PROSPECTUSES DATED OCTOBER 1, 2005 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

The Fund

INVESTMENT GOALS

The Fund seeks high current income and total return.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment goals by investing at least 80% of its net assets (plus any borrowings for investment purposes) in lower-rated corporate debt securities. These securities are:

. rated BB through D by Standard & Poor's;

. rated Ba through C by Moody's Investors Service, Inc.;

. comparably rated by another nationally recognized rating service; or

. unrated and believed by the Fund's investment advisor to be comparable in quality.

The Fund also seeks to achieve its investment goals by investing in debt securities issued by foreign governments and foreign companies, including securities issued in emerging market countries.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

The Fund also may invest in equity securities to seek capital appreciation. Equity securities include common stocks, preferred stocks, warrants and debt securities convertible into common stocks.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.


2

The Fund

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate
drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.


3

The Fund

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns
show the Fund's Class A share
performance for each of the
last ten complete calendar
years. They include the effects
of Fund expenses, but not the
effects of sales charges. If
sales charges were included,
these returns would be lower.

Average Annual Total Returns
are a measure of the Fund's
average performance over the
past one-year, five-year and
ten-year periods. The table
shows the returns of each share
class and includes the effects
of both Fund expenses and
current sales charges. Class B
share returns do not reflect
Class A share returns after
conversion of Class B shares to
Class A shares (see the section
"Your Account -- Sales
Charges").

The Fund's returns are compared
to the JP Morgan Global High
Yield Index ("JP Morgan
Index"), an unmanaged index
that is designed to mirror the
investible universe of the U.S.
dollar global high-yield
corporate debt market,
including domestic and
international issues. The
Fund's returns are also
compared to the Credit Suisse
First Boston High Yield Index
("CS First Boston Index"), an
unmanaged index that tracks the
performance of high-yield
bonds. Unlike the Fund, indices
are not investments, do not
incur fees, expenses or taxes
and are not professionally
managed. The Fund's returns are
also compared to the average
return of the funds included in
the Lipper High Current Yield
Funds Category ("Lipper
Average"), as calculated by
Lipper, Inc. This category is
composed of funds with
investment objectives similar
to those of the Fund. Sales
charges are not reflected in
the Lipper Average.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class B shares for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class B shares and the newer class of shares. Class A shares were initially offered on October 21, 1971, Class B shares were initially offered on June 8, 1992, and Class C shares were initially offered on January 15, 1996.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.

UNDERSTANDING EXPENSES

Sales Charges are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

Annual Fund Operating Expenses are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:
. $10,000 initial investment
. 5% total return for each year
. Fund operating expenses remain the same
. Reinvestment of all dividends and distributions
. Class B shares convert to Class A shares after eight years

(1) A $10 annual fee may be deducted from accounts of less than $1,000 and paid to the transfer agent.
(2) This charge applies only to certain Class A shares bought without an initial sales charge that are sold within 12 months of purchase.
(3) There is a $7.50 charge for wiring sale proceeds to your bank.

(1) Management fee has been restated to reflect contractual changes to the management fee for the Fund effective November 1, 2004.
(2) The Fund's distributor has voluntarily agreed to waive a portion of the 12b-1 fee for Class C shares. If this waiver were reflected in the table the 12b-1 fee for Class C shares would be 0.85% and total annual fund operating expenses for Class C shares would be 1.74%. This arrangement may be modified or terminated by the distributor at any time.

Example Expenses (your actual costs may be higher or lower)

Class                             1 Year 3 Years 5 Years 10 Years

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge ("CDSC") when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CHOOSING A SHARE CLASS

The Fund offers three classes
of shares in this prospectus --
Class A, B and C. Each share
class has its own sales charge
and expense structure.
Determining which share class
is best for you depends on the
dollar amount you are investing
and the number of years for
which you are willing to
invest. Purchases of $50,000 or
more but less than $1 million
can be made only in Class A or
Class C shares. Purchases of $1
million or more can be made
only in Class A shares. Based
on your personal situation,
your financial advisor can help
you decide which class of
shares makes the most sense for
you.

The Fund also offers an
additional class of shares,
Class Z shares, exclusively to
certain institutional and other
investors. Class Z shares are
made available through a
separate prospectus provided to
eligible institutional and
other investors.

Class A shares Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

Class A Sales Charges

                                 As a % of            % of offering

Class A shares bought without an initial sales charge in accounts aggregating up to $50 million at the time of purchase are subject to a 1.00% CDSC if the shares are sold within 12 months of the time of purchase. Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

Purchases Over $1 Million

Amount purchased                    Commission %
Less than $3 million                    1.00
------------------------------------------------
$3 million to less than $50 million     0.50
------------------------------------------------
$50 million or more                     0.25

For certain group retirement plans, financial advisors receive a 1.00% commission from the distributor on all purchases less than $3 million.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES
Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

Reduced Sales Charges for Larger Investments.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

Rights of Accumulation The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

Statement of Intent You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

. Individual accounts

. Joint accounts

. Certain IRA accounts

. Certain trusts

. UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax-related redemptions, or when the selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

Class B shares Your purchases of Class B shares are at Class B's net asset value. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the applicable chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the chart below.

Purchases of less than $50,000:

                              % deducted when

Automatic conversion to Class A shares occurs eight years after purchase.

Class C shares Your purchases of Class C shares are at Class C's net asset value. Although Class C shares have no front-end sales charge, they carry a CDSC of 1.00% that is applied to shares sold within the first year after they are purchased. After holding shares for one year, you may sell them at any time without paying a CDSC. The distributor pays your financial advisor an up-front commission of 1.00% on sales of Class C shares.

Class C Sales Charges

                              % deducted when

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable, you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.


14

Your Account

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

Rule 12b-1 Plan The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. The distributor has voluntarily agreed to waive a portion of the Class C share distribution fee so that it does not exceed 0.60% annually. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

Additional Intermediary Compensation In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS
The Fund may earn income from
the securities it holds. The
Fund also may realize capital
gains or losses on sales of its
securities. The Fund
distributes substantially all
of its net investment income
and capital gains to
shareholders. As a shareholder,
you are entitled to a portion
of the Fund's income and
capital gains based on the
number of shares you own at the
time these distributions are
declared.


16

Your Account

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.60% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended May 31, 2005.

PORTFOLIO MANAGERS

Kevin L. Cronk, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2003. Mr. Cronk has been associated with Columbia Advisors or its predecessors since August, 1999.

Thomas A. LaPointe, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2003. Mr. LaPointe has been associated with Columbia Advisors or its predecessors since February, 1999.

The Statement of Additional Information provides additional information about the managers' compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


18

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and CMG. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.


19

Managing the Fund

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

Other Investment Strategies and Risks

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.

(a) The Fund changed its fiscal year end from December 31 to May 31.
(b) Per share data was calculated using average shares outstanding during the period.
(c) Effective January 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and accreting discount on all debt securities. The effect of this change for the year ended December 31, 2001 was to increase net investment income per share by $0.05, decrease net realized and unrealized loss per share by $0.05 and increase the ratio of net investment income to average net assets from 9.76% to 10.34%. Per share data and ratios for periods prior to December 31, 2001 have not been restated to reflect this change in presentation.
(d) The per share net investment income amount does not reflect the period's reclassification of differences between book and tax basis net investment income.
(e) Total return at net asset value assuming all distributions reinvested and no initial sales charge or contingent deferred sales charge.
(f) Total return includes a voluntary reimbursement by the investment advisor for a realized investment loss. This reimbursement had an impact of less than 0.01% on the Fund's total return.
(g) Had the investment advisor not waived a portion of expenses, total return would have been reduced.
(h) Not annualized.
(i) The benefits derived from custody credits and directed brokerage arrangements, if applicable, had an impact of less than 0.01%.
(j) Annualized.
(k) Rounds to less than 0.01%.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B and C shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on October 21, 1971, and Class Z shares were initially offered on January 8, 1999.

2. The section "LEGAL PROCEEDINGS" under the heading "MANAGING THE FUND" is revised in its entirety as follows:

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

-2-

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

3. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last five fiscal years, which run from June 1 to May 31, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-months ended November 30, 2005 is audited. Other information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

Selected data for a share outstanding throughout each period is as follows:

The Fund

INVESTMENT GOALS

The Fund seeks high current income and total return.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its investment goals by investing at least 80% of its net assets (plus any borrowings for investment purposes) in lower-rated corporate debt securities. These securities are:

. rated BB through D by Standard & Poor's;

. rated Ba through C by Moody's Investors Service, Inc.;

. comparably rated by another nationally recognized rating service; or

. unrated and believed by the Fund's investment advisor to be comparable in quality.

The Fund also seeks to achieve its investment goals by investing in debt securities issued by foreign governments and foreign companies, including securities issued in emerging market countries.

The Fund may purchase derivative instruments, such as futures, options, swap contracts, and inverse floaters, to gain or reduce exposure to particular securities or segments of the bond markets. Derivatives are financial instruments whose values depend on, or are derived from, the value of an underlying security, index or currency. The Fund may use derivatives for both hedging and non-hedging purposes, such as to adjust the Fund's sensitivity to changes in interest rates, or to offset a potential loss in one position by establishing an opposite position. The Fund typically uses derivatives in an effort to achieve more efficiently economic exposures similar to those it could have achieved through the purchase and sale of fixed income securities. Investments in derivatives may be applied toward meeting a requirement to invest in a particular kind of investment if the derivatives have economic characteristics similar to investments of that kind.

The Fund also may invest in equity securities to seek capital appreciation. Equity securities include common stocks, preferred stocks, warrants and debt securities convertible into common stocks.

Additional strategies that are not principal investment strategies and the risks associated with them are described later in this prospectus under "Other Investment Strategies and Risks."

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goals. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with similar investment goals. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goals or perform favorably among comparable funds.

Interest rate risk is the risk of a change in the price of a bond when prevailing interest rates increase or decline. In general, if interest rates rise, bond prices fall, and if interest rates fall, bond prices rise. Changes in the values of bonds usually will not affect the amount of income the Fund receives from them but will affect the value of the Fund's shares. Interest rate risk is generally greater for bonds with longer maturities.

The Fund

Because the Fund may invest in debt securities issued or supported by private entities, including corporate bonds, the Fund is subject to issuer risk. Issuer risk is the possibility that changes in the financial condition of the issuer of a security, changes in general economic conditions, or changes in economic conditions that affect the issuer may impact its actual or perceived willingness or ability to make timely payments of interest or principal. This could result in a decrease in the price of the security and in some cases a decrease in income.

Reinvestment risk is the risk that income from the Fund's debt securities will decline if and when the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the current earnings rate of the Fund's portfolio.

Lower-rated debt securities, commonly referred to as "junk bonds," involve greater risk of loss due to credit deterioration and are less liquid, especially during periods of economic uncertainty or change, than higher-quality debt securities. Lower-rated debt securities generally have a higher risk that the issuer of the security may default and not make payment of interest or principal.

Derivatives involve special risks and may result in losses. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have had it invested in the underlying security. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility. The use of derivatives may also increase the amount of taxes payable by shareholders. Other risks arise from the Fund's potential inability to terminate or sell derivative positions. A liquid secondary market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. For more information on the risks of derivative strategies, see the Statement of Additional Information.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities denominated in foreign currencies and U.S. dollars, without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. The Fund may have limited legal recourse in the event of default with respect to certain debt securities issued by foreign governments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available

The Fund

information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Investments in emerging markets are subject to additional risk. The risks of foreign investments are typically increased in less developed countries, which are sometimes referred to as emerging markets. For example, political and economic structures in these countries may be new and developing rapidly, which may cause instability. These countries are also more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

Calendar Year Total Returns show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

Average Annual Total Returns are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effects of Fund expenses./(1)/

The Fund's returns are compared to the JP Morgan Global High Yield Index ("JP Morgan Index"), an unmanaged index that is designed to mirror the investible universe of the U.S. dollar global high-yield corporate debt market, including domestic and international issues. The Fund's returns are also compared to the Credit Suisse First Boston High Yield Index ("CS First Boston Index"), an unmanaged index that tracks the performance of high-yield bonds. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed. The Fund's returns are also compared to the average return of the funds included in the Lipper High Current Yield Funds Category ("Lipper Average"), as calculated by Lipper, Inc. This category is composed of funds with investment objectives similar to those of the Fund. Sales charges are not reflected in the Lipper Average.
(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on October 21, 1971, and Class Z shares were initially offered on January 8, 1999.

UNDERSTANDING EXPENSES

Annual Fund Operating Expenses are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

Example Expenses help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. It uses the following hypothetical conditions:

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

Important Things to Consider When Deciding on a Class of Shares:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

No minimum initial investment

. Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

. Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

. Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

. Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005; (iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

. Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

. Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

. Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

. Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

. Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.

CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus -- Class Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means
(i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing". The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


11

Your Account

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain funds impose a redemption fee on the proceeds of fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.


12

Your Account

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of the Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. Please also contact your financial service firm or intermediary for details about payments it may receive.

OTHER INFORMATION ABOUT YOUR ACCOUNT

How the Fund's Share Price is Determined The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value", that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

Account Fees If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

Share Certificates Share certificates are not available for Class Z shares.

Dividends, Distributions and Taxes The Fund has the potential to make the following distributions:

Types of Distributions

 Dividends      Represents interest and dividends earned from securities
                held by the Fund, net of expenses incurred by the Fund.
----------------------------------------------------------------------------
 Capital gains  Represents net long-term capital gains on sales of
                securities held for more than 12 months and net short-term
                capital gains, which are gains on sales of securities held
                for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

Distribution Options The Fund declares any dividends daily and pays them monthly, and declares and pays any capital gains (including short-term capital gains) at least annually. Shares begin to earn dividends on the date on which a purchase order is settled by payment. Shares stop earning dividends at the close of business on the day before the date on which a redemption order is settled. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

Distribution Options

Reinvest all distributions in additional shares of your current fund
Reinvest all distributions in shares of another fund

Receive dividends in cash (see options below) and reinvest capital gains
Receive all distributions in cash (with one of the following options):
. send the check to your address of record
. send the check to a third party address
. transfer the money to your bank via electronic funds transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

Tax Consequences Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

Managing the Fund

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Management by the Fund, amounted to 0.60% of average daily net assets of the Fund. A discussion of the factors considered by the Fund's Board of Trustees in approving the Fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended May 31, 2005.

PORTFOLIO MANAGERS

Kevin L. Cronk, a senior vice president of Columbia Advisors, is a co-manager for the Fund and has co-managed the Fund since February, 2003. Mr. Cronk has been associated with Columbia Advisors or its predecessors since August, 1999.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) ("CMD") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.


15

Managing the Fund

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders cannot currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and CMG. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.


16

Managing the Fund

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

Other Investment Strategies and Risks
----------------------------------------------------------------------------------------------------------------------

The Fund's principal investment strategies and their associated risks are described under "The Fund -- Principal Investment Strategies" and "The Fund -- Principal Investment Risks." This section describes other investments the Fund may make and the risks associated with them. In seeking to achieve its investment goals, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this prospectus. These types of securities and investment practices and their associated risks are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). The advisor may elect not to buy any of these securities or use any of these techniques. The Fund may not always achieve its investment goals. Except as otherwise noted, approval by the Fund's shareholders is not required to modify or change the Fund's investment goals or any of its investment strategies.

ZERO COUPON BONDS

Zero coupon bonds do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount. The value of these securities may fluctuate more than the value of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and distributed to its shareholders.

TEMPORARY DEFENSIVE STRATEGIES

At times, the advisor may determine that adverse market conditions make it desirable to temporarily suspend the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goals.


18

Financial Highlights

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last five fiscal years, which run from June 1 to May 31, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

(a) The Fund changed its fiscal year end from December 31 to May 31.
(b) Per share data was calculated using average shares outstanding during the period.
(c) Effective January 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and accreting discount on all debt securities.

Appendix A

Hypothetical Investment and Expense Information

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class B shares for periods prior to its inception. Class B shares would have substantially similar annual returns because Class B and Class C shares generally have similar expense structures.

4. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's financial performance. Information is shown for the Fund's last five fiscal years, which run from July 1 to June 30, unless otherwise indicated. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended December 31, 2005 is unaudited. Other information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

5. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

COLUMBIA SMALL CAP VALUE FUND I
COLUMBIA HIGH YIELD MUNICIPAL FUND
(EACH A "FUND" AND COLLECTIVELY, THE "FUNDS")

SUPPLEMENT TO THE PROSPECTUSES DATED NOVEMBER 1, 2005 (THE "PROSPECTUSES")

The Prospectuses are hereby supplemented with the following revised information relating to hypothetical investment and expense information:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in each class of the Fund assuming a 5% return each year, the cumulative return after fees and expenses, and the hypothetical year-end balance after fees and expenses. The charts also assume that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratios used for the Fund, which are the same as those stated in the Annual Fund Operating Expenses tables, are presented in the charts, and are net of any contractual fee waivers or expense reimbursements for the period of the contractual commitment. Your actual costs may be higher or lower. The tables shown below reflect the maximum initial sales charge but do not reflect any contingent deferred sales charges which may be payable on redemption. If contingent deferred sales charges were reflected, the "Hypothetical Year-End Balance After Fees and Expenses" amounts shown would be lower and the "Annual Fees and Expenses" amounts shown would be higher.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth by investing primarily in smaller capitalization equities.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in small capitalization stocks. Small capitalization stocks are stocks of companies with market capitalizations equal to or less than the largest stock in the Russell 2000 Value Index ($3.7 billion as of September 30, 2005). When purchasing securities for the Fund, the Fund's investment advisor may choose securities of companies it believes are undervalued. The Fund may invest up to 20% of its assets in foreign securities, including American Depositary Receipts.

UNDERSTANDING VALUE INVESTING

In managing the Fund, the advisor uses a value investing strategy that focuses on buying stocks cheaply when they are undervalued or "out of favor." The advisor buys stocks that have attractive current prices, consistent operating performance and/or favorable future growth prospects. The advisor's strategy uses fundamental business and financial analyses.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In


2

THE FUND

addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of its stock may fall, or may not approach the value the advisor has placed on it.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Smaller companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team. Stocks of smaller companies may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, smaller companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class A shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class A, B and C shares, including sales charges, compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class A share performance for each of the last ten complete calendar years. They include the effects of Fund expenses, but not the effects of sales charges. If sales charges were included, these returns would be lower.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's average performance over the past one-year, five-year and ten-year periods. The table shows the returns of each share class and includes the effects of both Fund expenses and current sales charges. Class B share returns do not reflect Class A share returns after conversion of Class B shares to Class A shares (see the section "Your Account -- Sales Charges").

The Fund's returns are compared to the Russell 2000 Value Index, an unmanaged index that tracks the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

THE FUND

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class C is a newer class of shares. Its performance information includes returns of the Fund's Class B shares for periods prior to its inception. Class B shares would have substantially similar annual returns because Class B and Class C shares generally have similar expense structures. Class A shares were initially offered on July 25, 1986, Class B shares were initially offered on November 9, 1992, and Class C shares were initially offered on January 15, 1996.

THE FUND

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

SALES CHARGES are paid directly by shareholders to Columbia Management Distributors, Inc., the Fund's distributor.

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees, 12b-1 fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

- Class B shares convert to Class A shares after eight years

YOUR ACCOUNT

HOW TO BUY SHARES

Your financial advisor can help you establish an appropriate investment portfolio, buy shares and monitor your investments. When the Fund receives your purchase request in "good form," your shares will be bought at the next calculated public offering price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, "good form" may mean that you have properly placed your order with your financial advisor or the Fund's transfer agent has received your completed application, including all necessary signatures. The USA Patriot Act may require us to obtain certain personal information from you which we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your customer information, we reserve the right to close your account or take such other steps as we deem reasonable.

INVESTMENT MINIMUMS

The initial investment minimum for the purchase of Class A, B and C shares is $1,000. For investors establishing an automatic investment plan, the initial investment minimum is $50. For participants in certain retirement plans, the initial investment minimum is $25. There is no minimum initial investment for wrap accounts. The Fund reserves the right to change these investment minimums. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of


8

YOUR ACCOUNT

the Fund and its shareholders. Please see the Statement of Additional Information for more details on investment minimums.

SALES CHARGES

You may be subject to an initial sales charge when you purchase, or a contingent deferred sales charge (CDSC) when you sell, shares of the Fund. These sales charges are described below. In certain circumstances, these sales charges may be reduced or waived, as described below and in the Statement of Additional Information.


CHOOSING A SHARE CLASS

The Fund offers three classes of shares in this prospectus -- CLASS A, B and C. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Purchases of $50,000 but less than $1 million can be made only in Class A or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers an additional class of shares, Class Z shares, exclusively to certain institutional and other investors. Class Z shares are made available through a separate prospectus provided to eligible institutional and other investors.

CLASS A SHARES Your purchases of Class A shares are made at the public offering price for these shares. This price includes a sales charge that is based on the amount of your initial investment when you open your account. The sales charge you pay on an additional investment is based on the total amount of your purchase and the current value of your account. Shares you purchase with reinvested dividends or other distributions are not subject to a sales charge. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class A shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

YOUR ACCOUNT

Subsequent Class A share purchases that bring your account value above $1 million (but less than $50 million) are subject to a CDSC if redeemed within 12 months of the date of purchase. The 12-month period begins on the first day of the month in which the purchase was made. The CDSC does not apply to retirement plans purchasing through a fee-based program.

For Class A share purchases of $1 million or more, financial advisors receive a cumulative commission from the distributor as follows:

UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B and C shares are subject to a CDSC, a sales charge applied at the time you sell your shares. You will pay the CDSC only on shares you sell within a certain amount of time after purchase. The CDSC generally declines each year until there is no charge for selling shares. The CDSC is applied to the net asset value at the time of purchase or sale, whichever is lower. For purposes of calculating the CDSC, the start of the holding period is the first day of the month in which the purchase was made. Shares you purchase with reinvested dividends or other distributions are not subject to a CDSC. When you place an order to sell shares, the Fund will automatically sell first those shares not subject to a CDSC and then those you have held the longest.

REDUCED SALES CHARGES FOR LARGER INVESTMENTS.

A. What are the principal ways to obtain a breakpoint discount?

There are two principal ways you may pay a lower sales charge (often referred to as "breakpoint discounts") when purchasing Class A shares of the Fund and other funds in the Columbia family of funds.

RIGHTS OF ACCUMULATION. The value of eligible accounts (regardless of class) maintained by you and each member of your immediate family may be combined with the value of your current purchase to reach a sales charge discount level (according to the chart on the previous page) and to obtain the lower sales charge for your current purchase. To calculate the combined value of the accounts, the Fund will use the shares' current public offering price.

STATEMENT OF INTENT. You also may pay a lower sales charge when purchasing Class A shares by signing a Statement of Intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the Statement of Intent within 13 months. As described in the chart on the previous page, the first breakpoint discount will be applied when total purchases reach $50,000. If your Statement of Intent purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to


10

YOUR ACCOUNT

that date. To calculate the total value of your Statement of Intent purchases, the Fund will use the historic cost (i.e. dollars invested) of the shares held in each eligible account. You must retain all records necessary to substantiate historic costs because the Fund and your financial intermediary may not maintain this information.

B. What accounts are eligible for breakpoint discounts?

The types of eligible accounts that may be aggregated to obtain one or both of the breakpoint discounts described above include:

- Individual accounts

- Joint accounts

- Certain IRA accounts

- Certain trusts

- UTMA/UGMA accounts

For the purposes of obtaining a breakpoint discount, members of your "immediate family" include your spouse, parent, step parent, legal guardian, child, step child, father in-law and mother in-law. Eligible accounts include those registered in the name of your dealer or other financial intermediary through which you own Columbia fund shares. The value of your investment in a Columbia money market fund held in an eligible account may be aggregated with your investments in other funds in the Columbia family of funds to obtain a breakpoint discount through a Right of Accumulation. Money market funds may also be included in the aggregation for a Statement of Intent for shares that have been charged a commission.

C. How do I obtain a breakpoint discount?

The steps necessary to obtain a breakpoint discount depend on how your account is maintained with the Columbia family of funds. To obtain any of the above breakpoint discounts, you must notify your financial advisor at the time you purchase shares of the existence of each eligible account maintained by you or your immediate family. It is the sole responsibility of your financial advisor to ensure that you receive discounts for which you are eligible and the Fund is not responsible for a financial advisor's failure to apply the eligible discount to your account. You may be asked by the Fund or your financial advisor for account statements or other records to verify your discount eligibility, including, where applicable, records for accounts opened with a different financial advisor and records of accounts established by members of your immediate family. If you own shares exclusively through an account maintained with the Fund's transfer agent, Columbia Management Services, Inc., you will need to provide the foregoing information to a Columbia Management Services, Inc. representative at the time you purchase shares.

D. How can I obtain more information about breakpoint discounts?

Certain investors, including affiliates of the Funds, broker/dealers and their affiliates, investors in wrap-fee programs, through fee-based advisers or certain retirement plans, certain shareholders of funds that were reorganized into the Funds as well as investors using the proceeds of redemptions of Fund shares or of certain Bank of America trust or similar accounts, may purchase shares at a reduced sales charge or net asset value, which is the value of a fund share excluding any sales charges. CDSCs may also be waived for redemptions under a systematic withdrawal program, in connection with the death or post-purchase disability of a shareholder, certain medical expenses, charitable gifts, involuntary and tax related redemptions, or when the


11

YOUR ACCOUNT

selling broker/dealer has agreed to waive or return its commission. Restrictions may apply to certain accounts and certain transactions. Further information regarding these discounts may be found in the Fund's Statement of Additional Information and at www.columbiafunds.com.

CLASS B SHARES Your purchases of Class B shares are at Class B's net asset value. Purchases of up to $50,000 are allowed in Class B shares assuming the combined value of the customer's total assets in the Columbia Funds does not exceed $50,000. Purchases in Class B shares that bring the combined value of a customer's total assets in excess of $50,000 will be rejected. A customer's total assets may include accounts for immediate family members. Group Plan accounts are valued at the plan level. Class B shares have no front-end sales charge, but they do carry a CDSC that is imposed only on shares sold prior to elimination of the CDSC as shown in the chart below. The CDSC generally declines each year and eventually disappears over time. The distributor pays your financial advisor an up-front commission on sales of Class B shares as described in the charts below.

HOW TO EXCHANGE SHARES

You may exchange your shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management Distributors, Inc. at net asset value. If your shares are subject to a CDSC, you will not be charged a CDSC upon the exchange. However, when you sell the shares acquired through the exchange, the shares sold may be subject to a CDSC, depending upon when you originally


12

YOUR ACCOUNT

purchased the shares you are exchanging. For purposes of computing the CDSC, the length of time you have owned your shares will be computed from the date of your original purchase and the applicable CDSC will be the CDSC of the original fund. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

Your financial advisor can help you determine if and when you should sell your shares. You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, (ii) if applicable you have included any certificates for shares to be sold, and (iii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund in any 28-day period, except as noted below with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), the Fund may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


14

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

RULE 12B-1 PLAN The Fund has adopted a plan under Rule 12b-1 that permits it to pay its distributor marketing and other fees to support the sale and distribution of Class A, B and C shares and certain services provided to you by your financial advisor. The annual service fee may equal up to 0.25% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.75% for each of Class B and Class C shares. Distribution and service fees are paid out of the assets of these classes. Over time, these fees will reduce the return on your investment and may cost you more than paying other types of sales charges. Class B shares automatically convert to Class A shares after eight years, eliminating the distribution fee upon conversion.

ADDITIONAL INTERMEDIARY COMPENSATION In addition to the commissions specified in this prospectus, the distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client


15

YOUR ACCOUNT

assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of each class of the Fund's shares is based on its net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value (plus any applicable sales charges) next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for each share class by dividing each class's total net assets by the number of that class's outstanding shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur


16

YOUR ACCOUNT

between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you will not be able to sell your shares until you have endorsed your certificates and returned them to the transfer agent.

DIVIDENDS, DISTRIBUTIONS, AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

17

YOUR ACCOUNT

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regard-less of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005, CMG converted to a limited liability company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.79% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

STEPHEN D. BARBARO, a vice president of Columbia Management, is a co-manager for the Fund and has managed or co-managed the Fund since June, 2002. Mr. Barbaro has been associated with Columbia Management or its predecessor since 1976.

JEREMY JAVIDI, a vice president of Columbia Management, is a co-manager of the Fund and has co-managed the Fund since August, 2005. Mr. Javidi has been associated with Columbia Management or its affiliates since January, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. ("CMD," formerly named Columbia Funds Distributor, Inc.) (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics


19

MANAGING THE FUND

oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and CMG. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.


20

MANAGING THE FUND

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The charts show the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class A, B, C and D shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The charts also assume that the annual expense ratios stay the same throughout the 10-year period, that all dividends and distributions are reinvested and that Class B shares convert to Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses tables, is reflected in the charts and is net of any fee waiver or expense reimbursement.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected,

-1-

the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on July 25, 1986 and Class Z shares were initially offered on July 31, 1995.

4. The section entitled "Financial Highlights" is updated and restated in its entirety as follows:

The financial highlights table is intended to help you understand the Fund's Class Z financial performance. Information is shown for the last five fiscal years, which run from July 1 to June 30, unless otherwise indicated. Certain information reflects financial results for a single Class Z share. The total returns in the table represent the rate that you would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). Information for the six-month period ended December 31, 2005 is unaudited. Other information has been derived from the Fund's financial statements which have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's annual report. You can request a free annual report containing those financial statements by calling 1-800-426-3750.

5. The section entitled "Legal Proceedings" is revised in its entirety as follows:

On February 9, 2005, Columbia Management Advisors, Inc. (which has since merged into Banc of America Capital Management, LLC (now named Columbia Management Advisors, LLC)) ("Columbia") and Columbia Funds Distributor, Inc. (which has been renamed Columbia Management Distributors, Inc.) (the "Distributor") (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates to reduce certain Columbia Funds (including the former Nations Funds) and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan developed by an independent distribution consultant and agreed to by the staff of the SEC. The independent distribution consultant has been in consultation with the Staff, and has submitted a draft proposed plan of distribution, but has not yet submitted a final proposed plan of distribution.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with the events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America and its affiliated entities.

On February 20, 2004, the Judicial Panel on Multidistrict Litigation transferred these cases and cases against several other mutual fund companies based on similar allegations to the United States District Court in Maryland for consolidated or coordinated pretrial proceedings (the "MDL"). Subsequently, additional related cases were transferred to the MDL. On September 29, 2004, the plaintiffs in the MDL filed amended and consolidated complaints. One of these amended complaints is a putative class action that includes claims under the federal securities

-3-

laws and state common law, and that names Columbia, the Distributor, the Trustees of the Columbia Funds, Bank of America Corporation and others as defendants. Another of the amended complaints is a derivative action purportedly on behalf of the Columbia Funds that asserts claims under federal securities laws and state common law.

On February 25, 2005, Columbia and other defendants filed motions to dismiss the claims in the pending cases. On March 1, 2006, for reasons stated in the court's memoranda dated November 3, 2005, the U.S. District Court for the District of Maryland granted in part and denied in part the defendants' motions to dismiss. The court dismissed all of the class action claims pending against the Columbia Funds. As to Columbia, the Distributor and the Trustees of the Columbia Funds, the claims under the Securities Act of 1933, the claims under Sections 34(b) and 36(a) of the Investment Company Act of 1940 (ICA) and the state law claims were dismissed. The claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and claims under Section 36(b) of the ICA along with related claims under Section 48(a) of the ICA were not dismissed.

On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption ("the CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has transferred the CDSC Lawsuit to the MDL.

The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any fund, if any, cannot currently be made.

In 2004, certain Columbia funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs filed a consolidated amended complaint on June 9, 2005. On November 30, 2005, the judge dismissed all claims by plaintiffs and ordered that the case be closed. The plaintiffs filed a notice of appeal on December 30, 2005 and this appeal is pending.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term growth by investing primarily in smaller capitalization equities.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in small capitalization stocks. Small capitalization stocks are stocks of companies with market capitalizations equal to or less than the largest stock in the Russell 2000 Value Index ($3.7 billion as of September 30, 2005). When purchasing securities for the Fund, the Fund's investment advisor may choose securities of companies it believes are undervalued. The Fund may invest up to 20% of its assets in foreign securities, including American Depositary Receipts.

UNDERSTANDING VALUE INVESTING

In managing the Fund, the advisor uses a value investing strategy that focuses on buying stocks cheaply when they are undervalued or "out of favor." The advisor buys stocks that have attractive current prices, consistent operating performance and/or favorable future growth prospects. The advisor's strategy uses fundamental business and financial analyses.

At times, the Fund's investment advisor may determine that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities. During such times, the Fund may, but is not required to, invest in cash or high-quality, short-term debt securities, without limit. Taking a temporary defensive position may prevent the Fund from achieving its investment goal.

In seeking to achieve its investment goal, the Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and, therefore, are not described in this prospectus. These types of securities and investment practices are identified and discussed in the Fund's Statement of Additional Information, which you may obtain free of charge (see back cover). Approval by the Fund's shareholders is not required to modify or change the Fund's investment goal or investment strategies.

PRINCIPAL INVESTMENT RISKS

The principal risks of investing in the Fund are described below. There are many circumstances (including additional risks that are not described here) which could prevent the Fund from achieving its investment goal. You may lose money by investing in the Fund.

Management risk means that the advisor's investment decisions might produce losses or cause the Fund to underperform when compared to other funds with a similar investment goal. Market risk means that security prices in a market, sector or industry may fall, reducing the value of your investment. Because of management and market risk, there is no guarantee that the Fund will achieve its investment goal or perform favorably among comparable funds.

The Fund may invest in real estate investment trusts ("REITs"). REITs are entities which either own properties or make construction or mortgage loans. REITs also may include operating or finance companies. Investing in REITs involves certain unique risks in addition to those risks associated with the real estate industry in general. The prices of REITs are affected by changes in the value of the underlying property owned by the REITs. In


2

THE FUND

addition, although the Fund does not invest directly in real estate, a REIT investment by the Fund is subject to certain of the risks associated with the ownership of real estate. These risks include possible declines in the value of real estate, risks related to general and local economic conditions, possible lack of availability of mortgage funds and changes in interest rates.

Since it purchases equity securities, the Fund is subject to equity risk. This is the risk that stock prices will fall over short or extended periods of time. Although the stock market has historically outperformed other asset classes over the long term, the stock market tends to move in cycles. Individual stock prices may fluctuate drastically from day to day and may underperform other asset classes over an extended period of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These price movements may result from factors affecting individual companies, industries or the securities market as a whole.

Value stocks are stocks of companies that may have experienced adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the advisor's opinion, undervalued. If the advisor's assessment of a company's prospects is wrong, the price of its stock may fall, or may not approach the value the advisor has placed on it.

Sector risk is inherent in the Fund's investment strategy. Companies that are in different but closely related industries are sometimes described as being in the same broad economic sector. The values of stocks of different companies in a market sector may be similarly affected by particular economic or market events. Although the Fund does not intend to focus on any particular sector, at times the Fund may have a large portion of its assets invested in a particular sector.

Foreign securities are subject to special risks. Foreign markets can be extremely volatile. Fluctuations in currency exchange rates may impact the value of foreign securities without a change in the intrinsic value of those securities. The liquidity of foreign securities may be more limited than that of domestic securities, which means that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees are generally higher for foreign investments. In addition, foreign governments may impose withholding taxes which would reduce the amount of income and capital gains available to distribute to shareholders. Other risks include possible delays in the settlement of transactions or in the notification of income; less publicly available information about companies; the impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of the company or its assets; and possible imposition of currency exchange controls.

Smaller companies are more likely than larger companies to have limited product lines, operating histories, markets or financial resources. They may depend heavily on a small management team. Stocks of smaller companies may trade less frequently, may trade in smaller volumes and may fluctuate more sharply in price than stocks of larger companies. In addition, smaller companies may not be widely followed by the investment community, which can lower the demand for their stocks.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class Z shares compare with those of broad measures of market performance for one year, five years and ten years. The chart and table are intended to illustrate some of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year. All returns include the reinvestment of dividends and distributions. Performance results include the effect of expense reduction arrangements, if any. If these arrangements had not been in place, the performance results would have been lower. Any expense reduction arrangements may be discontinued at any time. As with all mutual funds, past performance (before and after taxes) does not predict the Fund's future performance.

UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class Z share performance for each of the last ten complete calendar years. They include the effects of Fund expenses.

AVERAGE ANNUAL TOTAL RETURNS are a measure of the Fund's Class Z average performance over the past one-year, five-year and ten-year periods. They include the effect of Fund expenses.(1)

The Fund's returns are compared to the Russell 2000 Value Index, an unmanaged index that tracks the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on July 25, 1986 and Class Z shares were initially offered on July 31, 1995.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on each investor's own tax situation and may differ from those shown. After-tax returns may not be relevant to investors who hold Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Class Z is a newer class of shares. Its performance information includes returns of the Fund's Class A shares (the oldest existing fund class) for periods prior to its inception. These returns have not been restated to reflect any differences in expenses (such as Rule 12b-1 fees) between Class A shares and the newer class of shares. The Class A share returns have been adjusted to take into account the fact that Class Z shares are sold without sales charges. If differences in expenses had been reflected, the returns shown for periods prior to the inception of the newer class of shares would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees. Class A shares were initially offered on July 25, 1986 and Class Z shares were initially offered on July 31, 1995.

YOUR EXPENSES

Expenses are one of several factors to consider before you invest in a mutual fund. The tables below describe the fees and expenses you may pay when you buy, hold and sell shares of the Fund.


UNDERSTANDING EXPENSES

ANNUAL FUND OPERATING EXPENSES are paid by the Fund. They include management fees and other expenses that generally include, but are not limited to, administration, transfer agency, custody, and legal fees as well as costs related to state registration and printing of Fund documents. The specific fees and expenses that make up the Fund's other expenses will vary from time-to-time and may include fees or expenses not described here. The Fund may incur significant portfolio transaction costs that are in addition to the total annual fund operating expenses disclosed in the fee table. These transaction costs are made up of all costs that are associated with trading securities for the Fund's portfolio and include, but are not limited to, brokerage commissions and market spreads, as well as potential changes to the price of a security due to the Fund's efforts to purchase or sell it. While certain elements of transaction costs are readily identifiable and quantifiable, other elements that can make up a significant amount of the Fund's transaction costs are not.

EXAMPLE EXPENSES help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The table does not take into account any expense reduction arrangements discussed in the footnotes to the Annual Fund Operating Expenses table. It uses the following hypothetical conditions:

- $10,000 initial investment

- 5% total return for each year

- Fund operating expenses remain the same

- Reinvestment of all dividends and distributions

YOUR ACCOUNT

ELIGIBLE INVESTORS

Only Eligible Investors may purchase Class Z shares of the Fund, directly or by exchange. Class Z shares of the Fund generally are available only to certain "grandfathered" shareholders and to investors holding accounts with intermediaries that assess account level fees for the services they provide. Please read the following section for a more detailed description of the eligibility requirements. The Eligible Investors described below are subject to different minimum initial investment requirements.

IMPORTANT THINGS TO CONSIDER WHEN DECIDING ON A CLASS OF SHARES:

Broker-dealers, investment advisers or financial planners selling mutual fund shares may offer their clients more than one class of shares in a fund with different pricing options. This allows you and your financial advisor to choose among different types of sales charges and different levels of ongoing operating expenses, depending on the investment programs your financial advisor offers. Investors should consider carefully any separate transactions and other fees charged by these programs in connection with investing in any available share class before selecting a share class.

Eligibility for certain waivers, exemptions or share classes by new or existing investors may not be readily available or accessible through all intermediaries or all types of accounts offered by an intermediary. Accessibility of these waivers through a particular intermediary may also change at any time. If you believe you are eligible to purchase shares under a specific exemption, but are not permitted by your intermediary to do so, please contact your intermediary. You may be asked to provide information, including account statements and other records, regarding your eligibility.

Eligible Investors and their applicable investment minimums are as follows:

NO MINIMUM INITIAL INVESTMENT

- Any client of Bank of America Corporation or a subsidiary purchasing shares through an asset management company, trust, fiduciary, retirement plan administration or similar arrangement with Bank of America Corporation or the subsidiary;

- Any group retirement plan, including defined benefit and defined contribution plans such as: 401(k), 403(b), and 457(b) plans (but excluding individual retirement accounts ("IRAs")), for which an intermediary or other entity provides services and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent;

- Any investor purchasing through a Columbia Management Group state tuition plan organized under Section 529 of the Internal Revenue Code; or

- Any person investing all or part of the proceeds of a distribution, rollover or transfer of assets into a Columbia Management Individual Retirement Account, from any deferred compensation plan which was a shareholder of any of the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000, in which the investor was a participant and through which the investor invested in one or more of the funds of Columbia Acorn Trust immediately prior to the distribution, transfer or rollover.

$1,000 MINIMUM INITIAL INVESTMENT

- Any shareholder (as well as any family member of a shareholder or person listed on an account registration for any account of the shareholder) of a fund distributed by Columbia Management Distributors, Inc. (i) who

YOUR ACCOUNT

holds Class Z shares; (ii) who held Primary A shares prior to August 22, 2005;
(iii) who holds Class A shares that were obtained by exchange of Class Z shares; or (iv) who purchased certain no-load shares of a fund merged with a fund distributed by Columbia Management Distributors, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by Columbia Management Distributors, Inc.;

- Any employee (or family member of an employee) of Bank of America Corporation or a subsidiary;

- Any investor participating in an account offered by an intermediary or other entity that provides services to such an account, is paid an asset-based fee by the investor and is not compensated by the Fund for those services, other than payments for shareholder servicing or sub-accounting performed in place of the Fund's transfer agent (each investor purchasing through an intermediary must independently satisfy the $1,000 minimum investment requirement);

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, institution, government entity, or similar organization; which meets the respective qualifications for an accredited investor, as defined under the Securities Act of 1933; or

- Certain financial institutions and intermediaries, such as insurance companies, trust companies, banks, endowments, investment companies or foundations purchasing shares for its own account, including Bank of America Corporation, its affiliates, or subsidiaries.

The Fund reserves the right to change the criteria for Eligible Investors and the investment minimums. No minimum investment applies to accounts participating in the automatic investment plan; however, each investment requires a $25 minimum purchase. The Fund also reserves the right to refuse a purchase order for any reason, including if it believes that doing so would be in the best interest of the Fund and its shareholders.

YOUR ACCOUNT

SALES CHARGES

Your purchases of Class Z shares are at net asset value, which is the value of a Class Z share excluding any sales charge. Class Z shares are not subject to an initial sales charge when purchased or a contingent deferred sales charge when sold.


CHOOSING A SHARE CLASS

The Fund offers one class of shares in this prospectus --
CLASS Z.

The Fund also offers three additional classes of shares -- Class A, B and C shares are available through a separate prospectus. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the dollar amount you are investing and the number of years for which you are willing to invest. Based on your personal situation, your financial advisor can help you decide which class of shares makes the most sense for you. In general, anyone who is eligible to purchase Class Z shares, which do not incur Rule 12b-1 fees or sales charges, should do so in preference over other classes.

HOW TO EXCHANGE SHARES

You may exchange your shares for Class Z or Class A (only if Class Z is not offered) shares of another fund distributed by Columbia Management Distributors, Inc. at net asset value. Unless your account is part of a tax-deferred retirement plan, an exchange is a taxable event, and you may realize a gain or a loss for tax purposes. The Fund may terminate your exchange privilege if the advisor determines that your exchange activity is likely to adversely impact its ability to manage the Fund. See "Fund Policy on Trading of Fund Shares" for the Fund's policy. To exchange by telephone, call 1-800-422-3737. Please have your account and taxpayer identification numbers available when calling.

HOW TO SELL SHARES

You may sell shares of the Fund on any regular business day that the NYSE is open.

When the Fund receives your sales request in "good form," shares will be sold at the next calculated price. "Good form" means that the Fund's transfer agent has all information and documentation it deems necessary to effect your order. For example, when selling shares by letter of instruction, "good form" means (i) your letter has complete instructions, the proper signatures and Medallion Signature Guarantees, and (ii) any other required documents are attached. For additional documents required for sales by corporations, agents, fiduciaries, surviving joint owners and other legal entities, please call 1-800-345-6611. Retirement plan accounts have special requirements; please call 1-800-799-7526 for more information.

The Fund will generally send proceeds from the sale to you within seven days (usually on the next business day after your request is received in "good form"). However, if you purchased your shares by check, the Fund may delay sending the proceeds from the sale of your shares for up to 15 days after your purchase to protect against checks that are returned. No interest will be paid on uncashed redemption checks. Redemption proceeds may be paid in securities, rather than in cash, under certain circumstances. For more information, see the paragraph "Non-Cash Redemptions" under the section "How to Sell Shares" in the Statement of Additional Information.

FUND POLICY ON TRADING OF FUND SHARES

The interests of the Fund's long-term shareholders may be adversely affected by certain short-term trading activity by Fund shareholders. Such short-term trading activity, when excessive, has the potential to interfere with efficient portfolio management, generate transaction and other costs, dilute the value of Fund shares held by long-term shareholders and have other adverse effects on the Fund. This type of excessive short-term trading activity is referred to herein as "market timing." The Columbia Funds are not intended as vehicles for market timing. The Board of Trustees of the Fund has adopted the policies and procedures set forth below with respect to frequent trading of the Fund's shares.

The Fund, directly and through its agents, takes various steps designed to deter and curtail market timing. For example, if the Fund detects that any shareholder has conducted two "round trips" (as defined below) in the Fund that are deemed material by the Fund in any 28-day period, except as noted before with respect to orders received through omnibus accounts, the Fund will reject the shareholder's future purchase orders, including exchange purchase orders, involving any Columbia Fund (other than a Money Market Fund). In addition, if the Fund determines that any person, group or account has engaged in any type of market timing activity (independent of the two-round-trip limit), Columbia Funds may, in its discretion, reject future purchase orders by the person, group or account, including exchange purchase orders, involving the same or any other Columbia Fund, and also retains the right to modify these market timing policies at any time without prior notice.


12

YOUR ACCOUNT

The rights of shareholders to redeem shares of the Fund are not affected by any of the limits mentioned above. However, certain Funds impose a redemption fee on the proceeds of Fund shares that are redeemed or exchanged within 60 days of their purchase.

For these purposes, a "round trip" is a purchase by any means into a Columbia Fund followed by a redemption, of any amount, by any means out of the same Columbia Fund. Under this definition, an exchange into the Fund followed by an exchange out of the Fund is treated as a single round trip. Also for these purposes, where known, accounts under common ownership or control generally will be counted together. Accounts maintained or managed by a common intermediary, such as an adviser, selling agent or trust department, generally will not be considered to be under common ownership or control.

Purchases, redemptions and exchanges made through the Columbia Funds' Automatic Investment Plan, Systematic Withdrawal Plan or similar automated plans are not subject to the two-round-trip limit. The two-round-trip limit may be modified for, or may not be applied to, accounts held by certain retirement plans to conform to plan limits, considerations relating to the Employee Retirement Income Security Act of 1974 or regulations of the Department of Labor, and for certain asset allocation or wrap programs.

The practices and policies described above are intended to deter and curtail market timing in the Fund. However, there can be no assurance that these policies, individually or collectively, will be totally effective in this regard because of various factors. In particular, a substantial portion of purchase, redemption and exchange orders are received through omnibus accounts. Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple beneficial owners, are a common form of holding shares among financial intermediaries and retirement plans. The Fund typically is not able to identify trading by a particular beneficial owner through an omnibus account, which may make it difficult or impossible to determine if a particular account is engaged in market timing. Certain financial intermediaries have different policies regarding monitoring and restricting market timing in the underlying beneficial owner accounts that they maintain through an omnibus account that may be more or less restrictive than the Fund practices discussed above.

The Fund seeks to act in a manner that it believes is consistent with the best interests of Fund shareholders in making any judgments regarding market timing. Neither the Fund nor its agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

INTERMEDIARY COMPENSATION

The distributor, or its advisory affiliates, from their own resources, may make cash payments to financial service firms that agree to promote the sale of shares of funds that the distributor distributes. A number of factors may be considered in determining the amount of those payments, including the financial service firm's sales, client assets invested in the funds and redemption rates, the quality of the financial service firm's relationship with the distributor and/or its affiliates, and the nature of the services provided by financial service firms to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the financial service firm's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, the distributor may also pay non-cash compensation to financial service firms and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for financial service firm educational or training events.

YOUR ACCOUNT

In addition, the distributor, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the Fund. For further information about payments made by the distributor and its affiliates to financial service firms and intermediaries, please see the Statement of Additional Information. PLEASE ALSO CONTACT YOUR FINANCIAL SERVICE FIRM OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

OTHER INFORMATION ABOUT YOUR ACCOUNT

HOW THE FUND'S SHARE PRICE IS DETERMINED The price of the Fund's Class Z shares is based on their net asset value. The net asset value is determined at the close of regular trading on the NYSE, usually 4:00 p.m. Eastern time, on each business day that the NYSE is open for trading (typically Monday through Friday). Shares are not priced the days on which the NYSE is closed for trading.

When you request a transaction, it will be processed at the net asset value next determined after your request is received in "good form" by the distributor. In most cases, in order to receive that day's price, the distributor must receive your order before that day's transactions are processed. If you request a transaction through your financial advisor, your financial advisor must receive your order by the close of trading on the NYSE to receive that day's price.

The Fund determines its net asset value for its Class Z shares by dividing total net assets attributable to Class Z shares by the number of outstanding Class Z shares. In determining the net asset value, the Fund must determine the price of each security in its portfolio at the close of each trading day. Because the Fund holds securities that are traded on foreign exchanges, the value of the Fund's securities may change on days when shareholders will not be able to buy or sell Fund shares. This will affect the Fund's net asset value on the day it is next determined. Securities for which market quotations are available are valued each day at the current market value. However, where market quotations are unavailable, or when the advisor believes that subsequent events have made them unreliable, the Fund may use other data to determine the fair value of the securities.

The Fund has retained an independent fair value pricing service to assist in the fair valuation process for securities principally traded in a foreign market in order to adjust for possible changes in value that may occur between the close of the foreign exchange and the time at which Fund shares are priced. If a security is valued at a "fair value," that value may be different from the last quoted market price for the security.

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the heading of "Columbia." You can find daily prices for all share classes by visiting www.columbiafunds.com.

ACCOUNT FEES If your account value falls below $1,000 (other than as a result of depreciation in share value), your account may be subject to an annual fee of $10. The Fund's transfer agent will send you written notification of any such action and provide details on how you can add money to your account to avoid this penalty.

SHARE CERTIFICATES Share certificates are not available for Class Z shares.

DIVIDENDS, DISTRIBUTIONS, AND TAXES The Fund has the potential to make the following distributions:

TYPES OF DISTRIBUTIONS

Dividends              Represents interest and dividends earned from securities
                       held by the Fund, net of expenses incurred by the Fund.
-----------------------------------------------------------------------------------
Capital gains          Represents net long-term capital gains on sales of
                       securities held for more than 12 months and net short-term
                       capital gains, which are gains on sales of securities held
                       for a 12-month period or less.


UNDERSTANDING FUND DISTRIBUTIONS

The Fund may earn income from the securities it holds. The Fund also may realize capital gains or losses on sales of its securities. The Fund distributes substantially all of its net investment income and capital gains to shareholders. As a shareholder, you are entitled to a portion of the Fund's income and capital gains based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund distributes any dividends and any capital gains (including short-term capital gains) at least annually. You can choose one of the options listed in the table below for these distributions when you open your account. To change your distribution option, call 1-800-345-6611.

If you do not indicate on your application or at the time your account is established your preference for handling distributions, the Fund will automatically reinvest all distributions in additional shares of the Fund.

DISTRIBUTION OPTIONS

Reinvest all distributions in additional shares of your
current fund
----------------------------------------------------------------
Reinvest all distributions in shares of another fund
----------------------------------------------------------------
Receive dividends in cash (see options below) and reinvest
capital gains
----------------------------------------------------------------
Receive all distributions in cash (with one of the following
options):
  - send the check to your address of record
  - send the check to a third party address
  - transfer the money to your bank via electronic funds
    transfer

Distributions of $10 or less will automatically be reinvested in additional Fund shares. If you elect to receive distributions by check and the check is returned as undeliverable, the distribution, and all subsequent distributions, will be reinvested in additional shares of the Fund.

TAX CONSEQUENCES Unless you are an entity exempt from income taxes or invest under a retirement account, regardless of whether you receive your distributions in cash or reinvest them in additional Fund shares, all Fund distributions are subject to federal income tax. Depending on where you live, distributions also may be subject to state and local income taxes.

In general, any distributions of dividends, interest and short-term capital gains are taxable as ordinary income, unless such dividends are "qualified dividend income" (as defined in the Internal Revenue Code) eligible for a reduced rate of tax. Distributions of long-term capital gains are generally taxable as such, regardless of how long you have held your Fund shares. You will be provided with information each year regarding the amount of ordinary income and capital gains distributed to you for the previous year and any portion of your distribution

YOUR ACCOUNT

which is exempt from state and local taxes. Your investment in the Fund may have additional personal tax implications. Please consult your tax advisor about foreign, federal, state, local or other applicable tax laws.

In addition to the dividends and capital gains distributions made by the Fund, you may realize a capital gain or loss when selling or exchanging shares of the Fund. Such transactions also may be subject to federal, state and local income tax.

MANAGING THE FUND

INVESTMENT ADVISOR

Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, is the Fund's investment advisor. Columbia Advisors is responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors runs the Fund's day-to-day business, including placing all orders for the purchase and sale of the Fund's portfolio securities. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. Prior to June 15, 2005, CMG was a corporation. Effective June 15, 2005 CMG converted to a Limited Liability Company. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005, Columbia Management was the investment advisor to the Fund. As a result of the merger, Columbia Advisors is now the investment advisor to the Fund.

For the 2005 fiscal year, aggregate advisory fees paid to Columbia Advisors and/or Columbia Management by the Fund, not including pricing and bookkeeping and other fees paid to Columbia Advisors and/or Columbia Management by the Fund, amounted to 0.79% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

STEPHEN D. BARBARO, a vice president of Columbia Management, is a co-manager for the Fund and has managed or co-managed the Fund since June, 2002. Mr. Barbaro has been associated with Columbia Management or its predecessor since 1976.

JEREMY JAVIDI, a vice president of Columbia Management, is a co-manager of the Fund and has co-managed the Fund since August, 2005. Mr. Javidi has been associated with Columbia Management or its affiliates since January, 2000.

The Statement of Additional Information provides additional information about the manager's compensation, other accounts managed and ownership of securities in the Fund.

LEGAL PROCEEDINGS

On February 9, 2005, Columbia Management and Columbia Management Distributors, Inc. ("CMD," formerly named Columbia Funds Distributor, Inc.) (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud


17

MANAGING THE FUND

provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also voluntarily undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia Management and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC Order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the funds' independent trustees and not unacceptable to the staff of the SEC. At this time, the distribution plan is still under development. As such, any gain to the Fund or its shareholders can not currently be determined.

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of Fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the Columbia Funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

In connection with events described in detail above, various parties have filed suit against certain funds, the Trustees of the Columbia Funds, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). The fund derivative plaintiffs allege that the funds were harmed by market timing and late trading activity and seek, among other things, removal of the trustees of the funds, removal of Columbia Management and CMD, disgorgement of all management fees and monetary damages. The MDL is ongoing.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia Funds, the Trustees of the Columbia Funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits seek damages and allege, inter alia, that the fees and expenses paid by the funds are excessive and that the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On


18

MANAGING THE FUND

March 2, 2005, the actions were consolidated in the Massachusetts federal court as IN RE COLUMBIA ENTITIES LITIGATION. The plaintiffs filed a consolidated amended complaint on June 9, 2005.

On March 21, 2005, purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia Funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL.

APPENDIX A

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The following supplemental hypothetical investment information provides additional information about the effect of the expenses of the Fund, including investment advisory fees and other Fund costs, on the Fund's returns over a 10-year period. The chart shows the estimated expenses that would be charged on a hypothetical investment of $10,000 in Class Z shares of the Fund assuming a 5% return each year, the hypothetical year-end balance before expenses and the cumulative return after fees and expenses. The chart also assumes that the annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that stated in the Annual Fund Operating Expenses table, is reflected in the chart and is net of any fee waiver or expense reimbursement.

DESCRIPTION OF THE FUNDS

Each of the Funds is an open-end, management investment company. Each Fund, other than the Oregon Intermediate Municipal Bond Fund and the Technology Fund, is diversified, which means that, with respect to 75 percent of its total assets, the Fund will not invest more than 5 percent of its assets in the securities of any single issuer. The investment advisor for each of the Funds is Columbia Management Advisors, LLC (the "Advisor"). See the section entitled "INVESTMENT ADVISORY AND OTHER SERVICES PROVIDED BY AFFILIATES" for further information about the Advisor.

It is expected that, subject to shareholder approval, each Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

INVESTMENTS HELD AND INVESTMENT PRACTICES USED BY THE FUNDS

The Prospectus describes the fundamental investment objective and the principal investment strategy applicable to each Fund. The investment objective of each Fund, other than the Mid Cap Growth Fund, may not be changed without shareholder approval. The Mid Cap Growth Fund's Board of Directors may change its investment objective, without shareholder approval, upon 30 days written notice to all shareholders. What follows is additional information regarding securities in which a Fund may invest and investment practices in which it may engage. To determine whether a Fund purchases such securities or engages in such practices, see the chart on pages XX and XX of this Statement of Additional Information.

Securities Rating Agencies

Rating agencies are private services that provide ratings of the credit quality of fixed income securities. The following is a description of the fixed income securities ratings used by Moody's Investor Services, Inc. ("Moody's") and Standard & Poor's, a division of the McGraw-Hill Companies ("S&P"). Subsequent to its purchase by a Fund, a security may cease to be rated, or its rating may be reduced below the criteria set forth for the Fund. Neither event would require the elimination of the security from the Fund's portfolio, but the Advisor will consider that event in its determination of whether the Fund should continue to hold such security in its portfolio. Ratings assigned by a particular rating agency are not absolute standards of credit quality and do not evaluate market risk. Rating agencies may fail to make timely changes in credit ratings and an issuer's current financial condition may be better or worse than a rating indicates.

BOND RATINGS. MOODY'S -- The following is a description of Moody's bond ratings:

Aaa - Best quality; smallest degree of investment risk.

Aa - High quality by all standards.

Aa and Aaa are known as high-grade bonds.

A - Many favorable investment attributes; considered upper medium-grade obligations.

Baa - Medium-grade obligations; neither highly protected nor poorly secured. Interest and principal appear adequate for the present, but certain protective elements may be lacking or may be characteristically unreliable over any great length of time.

Ba - Speculative elements; future cannot be considered well assured. Protection of interest and principal payments may be very moderate and not well safeguarded during both good and bad times over the future.

B - Generally lack characteristics of a desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa - Poor standing, may be in default; elements of danger with respect to principal or interest.

S&P -- The following is a description of S&P's bond ratings:

3

AAA - Highest rating; extremely strong capacity to pay principal and interest.

AA - Also high-quality with a very strong capacity to pay principal and interest; differ from AAA issues only by a small degree.

A - Strong capacity to pay principal and interest; somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions.

BBB - Adequate capacity to pay principal and interest; normally exhibit adequate protection parameters, but adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay principal and interest than for higher-rated bonds.

Bonds rated AAA, AA, A, and BBB are considered investment grade bonds.

BB - Less near-term vulnerability to default than other speculative grade debt; face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to inadequate capacity to meet timely interest and principal payments.

B - Greater vulnerability to default but presently have the capacity to meet interest payments and principal repayments; adverse business, financial, or economic conditions would likely impair capacity or willingness to pay interest and repay principal.

CCC - Current identifiable vulnerability to default and dependent upon favorable business, financial, and economic conditions to meet timely payments of interest and repayments of principal. In the event of adverse business, financial, or economic conditions, they are not likely to have the capacity to pay interest and repay principal.

Bonds rated BB, B, and CCC are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal. BB indicates the least degree of speculation and CCC a higher degree of speculation. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions.

A Fund may purchase unrated securities (which are not rated by a rating agency) if the Advisor determines that a security is of comparable quality to a rated security that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that the Advisor may not accurately evaluate the security's comparative credit rating. Analysis of the creditworthiness of issuers of lower rated securities may be more complex than for issuers of higher-quality fixed income securities. To the extent that a Fund invests in unrated securities, the Fund's success in achieving its investment objective is determined more heavily by the Advisor's creditworthiness analysis than if the Fund invested exclusively in rated securities.

Non-Investment Grade Securities ("Junk Bonds")

Investments in securities rated below investment grade (i.e., rated Ba or lower by Moody's or BB or lower by S&P), which are eligible for purchase by certain of the Funds and, in particular, by the Conservative High Yield Fund, are described as "speculative" by both Moody's and S&P. Investments in lower rated corporate debt securities ("high yield securities" or "junk bonds") generally provide greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and principal and income risk. These high yield securities are regarded as predominately speculative with respect to the issuer's continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities.

High yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment grade securities. The prices of high yield securities have been found to be less sensitive to interest-rate changes than higher-rated investments, but more sensitive to adverse economic downturns or individual corporate developments. A projection of an economic downturn or of a period of rising interest rates, for example, could cause a decline in high yield security prices because the advent of a recession could lessen the ability of a highly leveraged company to make principal and interest payments on its debt securities. If an issuer of debt securities defaults, in addition to risking payment of all or a portion of interest and principal, the Funds investing in such securities may incur additional expenses to seek recovery.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield security, and could adversely affect the daily net asset value of the Fund's shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of high yield securities, especially in a thinly-traded market. Since secondary

4

markets for high yield securities are generally less liquid than the market for higher grade securities, it may be more difficult to value these securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation because there is less reliable, objective data available.

The use of credit ratings as the sole method of evaluating high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated. The Advisor does not rely solely on credit ratings when selecting securities for the Funds, and develops its own independent analysis of issuer credit quality.

Bank Obligations

Bank obligations in which the Funds may invest include certificates of deposit, bankers' acceptances, and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are "accepted" by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties, which vary depending upon market conditions and on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Bank obligations include foreign bank obligations including Eurodollar and Yankee obligations. Eurodollar bank obligations are dollar certificates of deposits and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks. Foreign bank obligations are subject to the same risks that pertain to domestic issues, notably credit risk and interest rate risk. Additionally, foreign bank obligations are subject to many of the same risks as investments in foreign securities (see "Foreign Equity Securities" below). Obligations of foreign banks involve somewhat different investment risks than those affecting obligations of United States banks, including the possibilities that their liquidity could be impaired because of future political and economic developments of the foreign bank's country, that their obligations may be less marketable than comparable obligations of United States banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted, which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Commercial Paper

A1 and Prime 1 are the highest commercial paper ratings issued by S&P and Moody's, respectively.

Commercial paper rated A1 by S&P has the following characteristics: (1) liquidity ratios are adequate to meet cash requirements; (2) long-term senior debt is rated A or better; (3) the issuer has access to at least two additional channels of borrowing; (4) basic earnings and cash flow have an upward trend with an allowance made for unusual circumstances; (5) typically, the issuer's industry is well established and the issuer has a strong position within the industry; and (6) the reliability and quality of management are unquestioned.

Among the factors considered by Moody's in assigning ratings are the following: (1) evaluation of the management of the issuer; (2) economic evaluation of the issuer's industry or industries and an appraisal of speculative-type risks which may be inherent in certain areas; (3) evaluation of the issuer's products in relation to competition and customer acceptance; (4) liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over a period of 10 years; (7) financial strength of a parent company and the relationships which exist with the issuer; and (8) recognition by the management of obligations that may be present or may arise as a result of public interest questions and preparation to meet such obligations.

Government Securities

Government securities may be either direct obligations of the U.S. Treasury or may be the obligations of an agency or instrumentality of the United States.

5

TREASURY OBLIGATIONS. The U.S. Treasury issues a variety of marketable securities that are direct obligations of the U.S. Government. These securities fall into three categories - bills, notes, and bonds - distinguished primarily by their maturity at time of issuance. Treasury bills have maturities of one year or less at the time of issuance, while Treasury notes currently have maturities of 1 to 10 years. Treasury bonds can be issued with any maturity of more than 10 years.

OBLIGATIONS OF AGENCIES AND INSTRUMENTALITIES. Agencies and instrumentalities of the U.S. Government are created to fill specific governmental roles. Their activities are primarily financed through securities whose issuance has been authorized by Congress. Agencies and instrumentalities include the Export Import Bank, Federal Housing Administration, Government National Mortgage Association, Tennessee Valley Authority, Banks for Cooperatives, Farmers Home Administration, Federal Home Loan Banks, Federal Intermediate Credit Banks, Federal Land Banks, Federal National Mortgage Association, Federal Home Loan Mortgage Corp., U.S. Postal System, and Federal Finance Bank. Although obligations of "agencies" and "instrumentalities" are not direct obligations of the U.S. Treasury, payment of the interest or principal on these obligations is generally backed directly or indirectly by the U.S. Government. This support can range from backing by the full faith and credit of the United States or U.S. Treasury guarantees to the backing solely of the issuing instrumentality itself.

Mortgage-Backed Securities and Mortgage Pass-Through Securities

Mortgage-backed securities are interests in pools of mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. Mortgage-backed securities are sold to investors by various governmental, government-related and private organizations as further described below. A Fund may also invest in debt securities that are secured with collateral consisting of mortgage-backed securities (see "Collateralized Mortgage Obligations") and in other types of mortgage-related securities.

Because principal may be prepaid at any time, mortgage-backed securities involve significantly greater price and yield volatility than traditional debt securities. A decline in interest rates may lead to a faster rate of repayment of the underlying mortgages and expose the Fund to a lower rate of return upon reinvestment. To the extent that mortgage-backed securities are held by a Fund, the prepayment right will tend to limit to some degree the increase in net asset value of the Fund because the value of the mortgage-backed securities held by the Fund may not appreciate as rapidly as the price of non-callable debt securities. When interest rates rise, mortgage prepayment rates tend to decline, thus lengthening the duration of mortgage-related securities and increasing their price volatility, affecting the price volatility of a Fund's shares.

Interests in pools of mortgage-backed securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment that consists of both interest and principal payments. In effect, these payments are a "pass-through" of the monthly payments made by the individual borrowers on their mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs incurred. Some mortgage-related securities (such as securities issued by the Government National Mortgage Association) are described as "modified pass-through." These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

The principal governmental guarantor of mortgage-related securities is the Government National Mortgage Association ("GNMA"). GNMA is a wholly-owned U.S. Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks, and mortgage bankers) and backed by pools of FHA-insured or VA-guaranteed mortgages. These guarantees, however, do not apply to the market value or yield of mortgage-backed securities or to the value of a Fund's shares. Also, GNMA securities often are purchased at a premium over the maturity value of the underlying mortgages. This premium is not guaranteed and will be lost if prepayment occurs.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include the Federal National Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC"). FNMA is a government-sponsored corporation owned entirely by private stockholders. It is subject to regulation by the Secretary of Housing and Urban Development. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) mortgages from a list of approved seller/servicers, which include state and federally-chartered savings and loan associations, mutual savings banks, commercial banks, credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government.

6

FHLMC is a corporate instrumentality of the U.S. Government and was created in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. Its stock is publicly owned. FHLMC issues Participation Certificates ("PCs"), which represent interests in conventional mortgages from FHLMC's national portfolio. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government.

Commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers, and other secondary market issuers also create pass-through pools of conventional mortgage loans. These issuers may, in addition, be the originators and/or servicers of the underlying mortgage loans as well as the guarantors of the mortgage-related securities. Pools created by non-governmental issuers generally offer a higher rate of interest than government and government-related pools because there are no direct or indirect government or agency guarantees of payment. However, timely payment of interest and principal of these pools may be supported by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance and letters of credit. The insurance and guarantees are issued by governmental entities, private insurers, and the mortgage poolers. Such insurance and guarantees and the creditworthiness of its issuers will be considered in determining whether a mortgage-related security meets a Fund's investment quality standards. There is no assurance that the private insurers or guarantors will meet their obligations under the insurance policies or guarantee arrangements. A Fund may buy mortgage-related securities without insurance or guarantees if, through an examination of the loan experience and practices of the originators/servicers and poolers, the Advisor determines that the securities meet the Fund's quality standards. Although the market for such securities is becoming increasingly liquid, securities issued by certain private organizations may not be readily marketable.

Collateralized Mortgage Obligations ("CMOs")

CMOs are hybrids between mortgage-backed bonds and mortgage pass-through securities. Similar to a bond, interest and prepaid principal are paid, in most cases, semiannually. CMOs may be collateralized by whole mortgage loans but are more typically collateralized by portfolios of mortgage pass-through securities, guaranteed by GNMA, FHLMC, or FNMA, and their income streams.

CMOs are structured into multiple classes, each bearing a different stated maturity. Actual maturity and average life will depend upon the prepayment experience of the collateral. CMOs provide for a modified form of call protection through a de facto breakdown of the underlying pool of mortgages according to how quickly the loans are repaid. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes receive principal only after the first class has been retired. An investor is partially protected against a sooner than desired return of principal by the sequential payments. The prices of certain CMOs, depending on their structure and the rate of prepayments, can be volatile. Some CMOs may also not be as liquid as other securities.

In a typical CMO transaction, a corporation issues multiple series, (e.g., A, B, C, Z) of CMO bonds ("Bonds"). Proceeds of the Bond offering are used to purchase mortgages or mortgage pass-through certificates ("Collateral"). The Collateral is pledged to a trustee as security for the Bonds. Principal and interest payments from the Collateral are used to pay principal on the Bonds in the order A, B, C, Z. The Series A, B, and C Bonds all pay interest currently. Interest on the Series Z Bond is accrued and added to principal and a like amount is paid as principal on the Series A, B, or C Bond currently being paid off. When the Series A, B, and C Bonds are paid in full, interest and principal on the Series Z Bond begins to be paid currently. With some CMOs, the issuer serves as a conduit to allow loan originators (primarily builders or savings and loan associations) to borrow against their loan portfolios.

A Fund will invest only in those CMOs whose characteristics and terms are consistent with the average maturity and market risk profile of the other fixed income securities held by the Fund.

Other Mortgage-Backed Securities

The Advisor expects that governmental, government-related or private entities may create mortgage loan pools and other mortgage-related securities offering mortgage pass-through and mortgage-collateralized investment in addition to those described above. The mortgages underlying these securities may include alternative mortgage instruments; that is, mortgage instruments whose principal or interest payments may vary or whose terms to maturity may differ from customary long-term fixed rate mortgages. As new types of mortgage-related securities are developed and offered to investors, the Advisor will, consistent with a Fund's investment objective, policies and quality standards, consider making investments in such new types of mortgage-related securities.

7

Other Asset-Backed Securities

The securitization techniques used to develop mortgage-backed securities are being applied to a broad range of assets. Through the use of trusts and special purpose corporations, various types of assets, including automobile loans, computer leases and credit card and other types of receivables, are being securitized in pass-through structures similar to mortgage pass-through structures described above or in a structure similar to the CMO structure. Consistent with a Fund's investment objectives and policies, the Fund may invest in these and other types of asset-backed securities that may be developed in the future. In general, the collateral supporting these securities is of shorter maturity than mortgage loans and is less likely to experience substantial prepayments with interest rate fluctuations.

These other asset-backed securities present certain risks that are not presented by mortgage-backed securities. Primarily, these securities may not have the benefit of any security interest in the related assets. Credit card receivables are generally unsecured and the debtors are entitled to the protection of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. There is the possibility that recoveries on repossessed collateral may not, in some cases, be available to support payments on these securities.

Asset-backed securities are often backed by a pool of assets representing the obligations of a number of direct parties. To reduce the effect of failures by obligors on underlying assets to make payments, the securities may contain elements of credit support which fall into two categories: (i) liquidity protection and (ii) protection against losses resulting from ultimate default by an obligor or the underlying assets. Liquidity protection refers to the making of advances, generally by the entity administering the pool of assets, to ensure that the receipt of payments on the underlying pool occurs in a timely fashion. Protection against losses results from payment of the insurance obligations on at least a portion of the assets in the pool. This protection may be provided through guarantee policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches. The Fund will not pay any additional or separate fees for credit support. The degree of credit support provided for each issue is generally based on historical information respecting the level of credit risk associated with the underlying assets. Delinquency or loss in excess of that anticipated, or failure of the credit support could adversely affect the return on an investment in such a security.

Floating or Variable Rate Securities

Floating or variable rate securities have interest rates that periodically change according to the rise and fall of a specified interest rate index or a specific fixed-income security that is used as a benchmark. The interest rate typically changes every six months, but for some securities the rate may fluctuate weekly, monthly, or quarterly. The index used is often the rate for 90- or 180-day Treasury Bills. Variable-rate and floating-rate securities may have interest rate ceilings or caps that fix the interest rate on such a security if, for example, a specified index exceeds a predetermined interest rate. If an interest rate on a security held by the Fund becomes fixed as a result of a ceiling or cap provision, the interest income received by the Fund will be limited by the rate of the ceiling or cap. In addition, the principal values of these types of securities will be adversely affected if market interest rates continue to exceed the ceiling or cap rate.

Loan Transactions

Loan transactions involve the lending of securities to a broker-dealer or institutional investor for its use in connection with short sales, arbitrage, or other securities transactions. If made, loans of portfolio securities by a Fund will be in conformity with applicable federal and state rules and regulations. The purpose of a qualified loan transaction is to afford a Fund the opportunity to continue to earn income on the securities loaned and at the same time to earn income on the collateral held by it.

It is the view of the Staff of the Securities and Exchange Commission ("SEC") that a Fund is permitted to engage in loan transactions only if the following conditions are met: (1) the Fund must receive at least 100 percent collateral in the form of cash or cash equivalents, e.g., U.S. Treasury bills or notes, or an irrevocable letter of credit; (2) the borrower must increase the collateral whenever the market value of the securities loaned (determined on a daily basis) rises above the level of the collateral; (3) the Fund must be able to terminate the loan, after notice, at any time; (4) the Fund must receive reasonable interest on the loan or a flat fee from the borrower, as well as amounts equivalent to any dividends, interest, or other distributions on the securities loaned and any increase in market value; (5) the Fund may pay only reasonable custodian fees in connection with the loan; (6) voting rights on the securities loaned may pass to the borrower; however, if a material event affecting the investment occurs, the Board of Directors must be able to terminate the loan and vote proxies or enter into an alternative arrangement with the borrower to enable the Board to vote proxies. Excluding items (1) and
(2), these practices may be amended from time to time as regulatory provisions permit.

While there may be delays in recovery of loaned securities or even a loss of rights in collateral supplied if the borrower fails financially, loans will be made only to firms deemed by the Advisor to be of good standing and will not be made unless, in the judgment of the Advisor, the consideration to be earned from such loans would justify the risk.

Options and Financial Futures Transactions

Certain Funds may invest up to 5 percent of their net assets in premiums on put and call exchange-traded options. A call option gives the holder (buyer) the right to purchase a security at a specified price (the exercise price) at any time until a certain date (the expiration date). A put option gives the buyer the right to sell a security at the exercise price at any time until the expiration date. The Fund may also purchase options on securities indices. Options on securities indices are similar to options on a security except that, rather than the right to take or make delivery of a security at a specified price, an option on a securities index gives the holder the right to receive, on exercise of the option, an amount of cash if the closing level of the securities index on which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. A Fund may enter into closing transactions, exercise its options, or permit the options to expire.

A Fund may also write call options, but only if such options are covered. A call option is covered if written on a security a Fund owns or if the Fund has an absolute and immediate right to acquire that security without additional cash consideration upon conversion or exchange of other securities held by the Fund. If additional cash consideration is required, that amount must be held in a segregated account by the Fund's custodian bank. A call option on a securities index is covered if the Fund owns securities whose price changes, in the opinion of the Advisor, are expected to be substantially similar to those of the index. A call option may also be covered in any other manner in accordance with the rules of the exchange upon which the option is traded and applicable laws and regulations. Each Fund that is permitted to engage in option transactions may write such options on up to 25 percent of its net assets.

Financial futures contracts, including interest rate futures transactions, are commodity contracts that obligate the long or short holder to take or make delivery of a specified quantity of a financial instrument, such as a security or the cash value of a securities index, during a specified future period at a specified price. The investment restrictions regarding financial futures transactions do not limit the percentage of the Fund's assets that may be invested in financial futures transactions. None of the Funds, however, intend to enter into financial futures transactions for which the aggregate initial margin exceeds 5 percent of the net assets of the Fund after taking into account unrealized profits and unrealized losses on any such transactions it has entered into. A Fund may engage in futures transactions only on commodities exchanges or boards of trade.

A Fund will not engage in transactions in index options, financial futures contracts, or related options for speculation. A Fund may engage in these transactions only as an attempt to hedge against market conditions affecting the values of securities that the Fund owns or intends to purchase. When a Fund purchases a put on a stock index or on a stock index future not held by the Fund, the put protects the Fund against a decline in the value of all securities held by it to the extent that the stock index moves in a similar pattern to the prices of the securities held. The correlation, however, between indices and price movements of the securities in which a Fund will generally invest may be imperfect. It is expected, nonetheless, that the use of put options that relate to such indices will, in certain circumstances, protect against declines in values of specific portfolio securities or the Fund's portfolio generally. Although the purchase of a put option may partially protect a Fund from a decline in the value of a particular security or its portfolio generally, the cost of a put will reduce the potential return on the security or the portfolio if either increases in value.

Upon entering into a futures contract, a Fund will be required to deposit with its custodian in a segregated account cash, certain U.S. Government securities, or any other portfolio assets as permitted by the SEC's rules and regulations in an amount known as the "initial margin." This amount, which is subject to change, is in the nature of a performance bond or a good faith deposit on the contract and would be returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied.

The principal risks of options and futures transactions are: (a) possible imperfect correlation between movements in the prices of options, currencies, or futures contracts and movements in the prices of the securities or currencies hedged or used for cover; (b) lack of assurance that a liquid secondary market will exist for any particular options or futures contract when needed; (c) the need for additional skills and techniques beyond those required for normal portfolio management; (d) losses on futures contracts resulting from market movements not anticipated by the Advisor; and (e) possible need to defer closing out certain options or futures contracts to continue to qualify for beneficial tax treatment afforded "regulated investment companies" under the Internal Revenue Code of 1986, as amended (the "Code").

Swap Agreements ("Swaps," "Caps," "Collars" and "Floors")

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

9

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

Foreign Equity Securities

Foreign equity securities include common stock and preferred stock, including securities convertible into equity securities, issued by foreign companies, American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs"). In determining whether a company is foreign, the Advisor will consider various factors including where the company is headquartered, where the company's principal operations are located, where the company's revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending upon the circumstances.

Foreign equity securities, which are generally denominated in foreign currencies, involve risks not typically associated with investing in domestic securities. Foreign securities may be subject to foreign taxes that would reduce their effective yield. Certain foreign governments levy withholding taxes against dividend and interest income. Although in some countries a portion of these taxes is recoverable, the unrecovered portion of any foreign withholding taxes would reduce the income a Fund receives from its foreign investments.

Foreign investments involve other risks, including possible political or economic instability of the country of the issuer, the difficulty of predicting international trade patterns, and the possibility of currency exchange controls. Foreign securities may also be subject to greater fluctuations in price than domestic securities. There may be less publicly available information about a foreign company than about a domestic company. Foreign companies generally are not subject to uniform accounting, auditing, and financial reporting standards comparable to those of domestic companies.

There is generally less government regulation of stock exchanges, brokers, and listed companies abroad than in the United States. In addition, with respect to certain foreign countries, there is a possibility of the adoption of a policy to withhold dividends at the source, or of expropriation, nationalization, confiscatory taxation, or diplomatic developments that could affect investments in those countries. Finally, in the event of default on a foreign debt obligation, it may be more difficult for a Fund to obtain or enforce a judgement against the issuers of the obligation. The Funds will normally execute their portfolio securities transactions on the principal stock exchange on which the security is traded.

The considerations noted above regarding the risk of investing in foreign securities are generally more significant for investments in emerging or developing countries, such as countries in Eastern Europe, Latin America, South America or Southeast Asia. These countries may have relatively unstable governments and securities markets in which only a small number of securities trade. Markets of developing or emerging countries may generally be more volatile than markets of developed countries. Investment in these markets may involve significantly greater risks, as well as the potential for greater gains.

ADRs in registered form are dollar-denominated securities designed for use in the U.S. securities markets. ADRs are sponsored and issued by domestic banks and represent and may be converted into underlying foreign securities deposited with the domestic bank or a correspondent bank. ADRs do not eliminate the risks inherent in investing in the securities of foreign issuers. By investing in ADRs rather than directly in the foreign security, however, a Fund may avoid currency risks during the settlement period for either purchases or sales. There is a large, liquid market in the United States for most ADRs. GDRs are receipts representing an arrangement with a major foreign bank similar to that for ADRs. GDRs are not necessarily denominated in the currency of the underlying security. While ADRs and GDRs

10

will generally be considered foreign securities for purposes of calculation of any investment limitation placed on a Fund's exposure to foreign securities, these securities, along with the securities of foreign companies traded on NASDAQ will not be subject to any of the restrictions placed on the Funds' ability to invest in emerging market securities.

Additional costs may be incurred in connection with a Fund's foreign investments. Foreign brokerage commissions are generally higher than those in the United States. Expenses may also be incurred on currency conversions when a Fund moves investments from one country to another. Increased custodian costs as well as administrative difficulties may be experienced in connection with maintaining assets in foreign jurisdictions.

Foreign Fixed Income Securities

Foreign fixed income securities include debt securities of foreign corporate issuers, certain foreign bank obligations (see "Bank Obligations"), obligations of foreign governments or their subdivisions, agencies and instrumentalities, and obligations of supranational entities such as the World Bank, the European Investment Bank, and the Asian Development Bank. Any of these securities may be denominated in foreign currency or U.S. dollars, or may be traded in U.S. dollars in the United States although the underlying security is usually denominated in a foreign currency.

The risks of investing in foreign fixed income securities are the same as the risks of investing in foreign equity securities. Additionally, investment in sovereign debt (debt issued by governments and their agencies and instrumentalities) can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be available or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity's willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity's policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities may also depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a governmental entity's implementation of economic reforms and/or economic performance and the timely service of such debtor's obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties' commitments to lend funds to the governmental entity, which may further impair such debtor's ability or willingness to service its debts in a timely manner. Consequently, governmental entities may default on their sovereign debt. Holders of sovereign debt (including the Funds) may be requested to participate in the rescheduling of such debt and to the extend further loans to governmental entities. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

Currency Contracts

The value of a Fund invested in foreign securities will fluctuate as a result of changes in the exchange rates between the U.S. dollar and the currencies in which the foreign securities or bank deposits held by the Fund are denominated. To reduce or limit exposure to changes in currency exchange rates (referred to as "hedging"), a Fund may enter into forward currency exchange contracts that, in effect, lock in a rate of exchange during the period of the forward contracts. Forward contracts are usually entered into with currency traders, are not traded on securities exchanges, and usually have a term of less than one year, but can be renewed. A default on a contract would deprive a Fund of unrealized profits or force a Fund to cover its commitments for purchase or sale of currency, if any, at the market price. A Fund will enter into forward contracts only for hedging purposes and not for speculation. If required by the Investment Company Act of 1940, as amended (the "1940 Act") or the SEC, a Fund may "cover" its commitment under forward contracts by segregating cash or liquid securities with a Fund's custodian in an amount not less than the current value of the Fund's total assets committed to the consummation of the contracts. A Fund may also purchase or sell foreign currencies on a "spot" (cash) basis or on a forward basis to lock in the U.S. dollar value of a transaction at the exchange rate or rates then prevailing. A Fund will use this hedging technique in an attempt to insulate itself against possible losses resulting from a change in the relationship between the U.S. dollar and the relevant foreign currency during the period between the date a security is purchased or sold and the date on which payment is made or received.

Hedging against adverse changes in exchange rates will not eliminate fluctuation in the prices of a Fund's portfolio securities or prevent loss if the prices of those securities decline. In addition, the use of forward contracts may limit potential gains from an appreciation in the U.S. dollar value of a foreign currency. Forecasting short-term currency market movements is very difficult, and there is no assurance that short-term hedging strategies used by a Fund will be successful.

Real Estate Investment Trusts ("REITs")

REITs are pooled investment vehicles that invest primarily in real estate--such as shopping centers, malls, multi-family housing, or commercial property, or real-estate related loans such as mortgages. Investing in REITs involves unique risks and may be affected by changes in the value of the underlying property owned by the REIT or affected by the quality of the credit extended. REITs are significantly affected by the market for real estate and are subject to many of the same risks associated with direct ownership in real estate. Furthermore, REITs are dependent upon management skills and subject to heavy cash flow dependency.

Repurchase Agreements

A Fund may invest in repurchase agreements, which are agreements by which the Fund purchases a security and simultaneously commits to resell that security to the seller (a commercial bank or securities dealer) at a stated price within a number of days (usually not more than seven) from the date of purchase. The resale price reflects the purchase price plus a rate of interest that is unrelated to the coupon rate or maturity of the purchased security. Repurchase agreements may be considered loans by the Fund collateralized by the underlying security. The obligation of the seller to pay the stated price is in effect secured by the underlying security. The seller will be required to maintain the value of the collateral underlying any repurchase agreement at a level at least equal to the price of the repurchase agreement. In the case of default by the seller, the Fund could incur a loss. In the event of a bankruptcy proceeding commenced against the seller, the Fund may incur costs and delays in realizing upon the collateral. A Fund will enter into repurchase agreements only with those banks or securities dealers who are deemed creditworthy pursuant to criteria adopted by the Advisor. There is no limit on the portion of a Fund's assets that may be invested in repurchase agreements with maturities of seven days or less.

Borrowing

A Fund may borrow from a bank for temporary administrative purposes. This borrowing may be unsecured. Provisions of the 1940 Act require a Fund to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300 percent of the amount borrowed, with an exception for borrowings not in excess of 5 percent of the Fund's total assets made for temporary administrative purposes. Any borrowings for temporary administrative purposes in excess of 5 percent of a Fund's total assets are subject to continuous asset coverage. If the 300 percent asset coverage declines as a result of market fluctuations or other reasons, a Fund may be required to sell some of its portfolio holdings within three days to reduce the debt and restore the 300 percent asset coverage. Notwithstanding the above, certain of the Funds may not borrow in excess of 5 percent of their assets at any time. A Fund also may enter into certain transactions, including reverse repurchase agreements, mortgage dollar rolls, and sale-buybacks, that can be viewed as constituting a form of borrowing or financing transaction by the Fund. To the extent a Fund covers its commitment under such transactions (or economically similar transaction) by the segregation of assets determined in accordance with procedures adopted by the Board of Directors, equal in value to the amount of the Fund's commitment to repurchase, such an agreement will not be considered a "senior security" by the Fund and therefore will not be subject to the 300 percent asset coverage requirement otherwise applicable to borrowings by the Fund. Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of a Fund's portfolio. Money borrowed will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased. A Fund also may be required to maintain minimum average balances in connection with such borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

Illiquid Securities

Illiquid securities are securities that may not be sold or disposed of in the ordinary course of business within seven days at approximately the price used to determine the Fund's net asset value. Under current interpretations of the Staff of the SEC, the following instruments in which a Fund may invest will be considered illiquid: (1) repurchase agreements maturing in more than seven days; (2) restricted securities (securities whose public resale is subject to legal restrictions, except as described in the following paragraph); (3) options, with respect to specific securities, not traded on a national securities exchange that are not readily marketable; and (4) any other securities in which a Fund may invest that are not readily marketable.

Notwithstanding the restrictions applicable to investments in illiquid securities described in the relevant chart below, the Funds may purchase without limit certain restricted securities that can be resold to qualifying institutions pursuant to a regulatory exemption under Rule 144A ("Rule 144A securities"). If a dealer or institutional trading market exists for Rule 144A securities, such securities are deemed to be liquid and thus exempt from that Fund's liquidity restrictions.

Under the supervision of the Board of Directors of the Funds, the Advisor determines the liquidity of the Funds' portfolio securities, including Rule 144A securities, and, through reports from the Advisor, the Board of Directors monitors trading activity in these

12

securities. In reaching liquidity decisions, the Advisor will consider, among other things, the following factors: (1) the frequency of trades and quotes for the security; (2) the number of dealers willing to purchase or sell the security and the number of other potential purchasers; (3) dealer undertakings to make a market in the security; and (4) the nature of the security and the marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the procedures for the transfer). If institutional trading in Rule 144A securities declines, a Fund's liquidity could be adversely affected to the extent it is invested in such securities.

Convertible Securities and Warrants

Convertible debentures are interest-bearing debt securities, typically unsecured, that represent an obligation of the corporation providing the owner with claims to the corporation's earnings and assets before common and preferred stock owners, generally on par with unsecured creditors. If unsecured, claims of convertible debenture owners would be inferior to claims of secured debt holders. Convertible preferred stocks are securities that represent an ownership interest in a corporation providing the owner with claims to the corporation's earnings and assets before common stock owners, but after bond owners. Investments by a Fund in convertible debentures or convertible preferred stock would be a substitute for an investment in the convertible security if available in quantities necessary to satisfy the Fund's investment needs (for example, in the case of a new issuance of convertible securities) or where, because of financial market conditions, the conversion price of the convertible security is comparable to the price of the underlying common stock, in which case a preferred position with respect to the corporation's earnings and assets may be preferable to holding common stock.

Warrants are options to buy a stated number of underlying securities at a specified price any time during the life of the warrants. The securities underlying these warrants will be the same types of securities that a Fund will invest in to achieve its investment objective of capital appreciation. The purchaser of a warrant expects the market price of the underlying security will exceed the purchase price of the warrant plus the exercise price of the warrant, thus resulting in a profit. If the market price never exceeds the purchase price plus the exercise price of the warrant before the expiration date of the warrant, the purchaser will suffer a loss equal to the purchase price of the warrant.

To the extent the Conservative High Yield Fund acquires common stock through exercise of conversion rights or warrants or acceptance of exchange or similar offers, the common stock will not be retained in the portfolio. Orderly disposition of these equity securities will be made consistent with management's judgment as to the best obtainable price.

Dollar Roll Transactions

"Dollar roll" transactions consist of the sale by a Fund to a bank or broker-dealer (the "counterparty") of GNMA certificates or other mortgage-backed securities together with a commitment to purchase from the counterparty similar, but not identical, securities at a future date and at agreed price. The counterparty receives all principal and interest payments, including prepayments, made on the security while it is the holder. The Fund receives a fee from the counterparty as consideration for entering into the commitment to purchase. Dollar rolls may be renewed over a period of several months with a new purchase and repurchase price fixed and a cash settlement made at each renewal without physical delivery of securities. Moreover, the transaction may be preceded by a firm commitment agreement pursuant to which the Fund agrees to buy a security on a future date.

A Fund will not use such transactions for leveraging purposes and, accordingly, will segregate liquid assets in an amount sufficient to meet their purchase obligations under the transactions. The Funds will also maintain asset coverage of at least 300 percent for all outstanding firm commitments, dollar rolls and other borrowings.

Dollar rolls may be treated for purposes of the 1940 Act as borrowings of the Fund because they involve the sale of a security coupled with an agreement to repurchase. Like all borrowings, a dollar roll involves costs to the Fund. For example, while a Fund receives a fee as consideration for agreeing to repurchase the security, the Fund forgoes the right to receive all principal and interest payments while the counterparty holds the security. These payments received by the counterparty may exceed the fee received by the Fund, thereby effectively charging the Fund interest on its borrowing. Further, although the Fund can estimate the amount of expected principal prepayment over the term of the dollar roll, a variation in the actual amount of prepayment could increase or decease the cost of the Fund's borrowing.

When-Issued Securities

When-issued, delayed-delivery and forward transactions generally involve the purchase of a security with payment and delivery in the future (i.e., beyond normal settlement). A Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. New issues of stocks and bonds, private placements and U.S. Government

13

securities may be sold in this manner. To the extent a Fund engages in when-issued and delayed-delivery transactions, it will do so to acquire portfolio securities consistent with its investment objectives and policies and not for investment leverage. A Fund may use spot and forward currency exchange transactions to reduce the risk associated with fluctuations in exchange rates when securities are purchased or sold on a when-issued or delayed delivery basis.

Zero-Coupon and Pay-in-Kind Securities

A zero-coupon security has no cash coupon payments. Instead, the issuer sells the security at a substantial discount from its maturity value. The interest equivalent received by the investor from holding this security to maturity is the difference between the maturity value and the purchase price. Pay-in-kind securities are securities that pay interest in either cash or additional securities, at the issuer's option, for a specified period. The price of pay-in-kind securities is expected to reflect the market value of the underlying accrued interest, since the last payment. Zero-coupon and pay-in-kind securities are more volatile than cash pay securities. The Fund accrues income on these securities prior to the receipt of cash payments. The Fund intends to distribute substantially all of its income to its shareholders to qualify for pass-through treatment under the tax laws and may, therefore, need to use its cash reserves to satisfy distribution requirements.

Temporary Investments

When, as a result of market conditions, the Advisor determines a temporary defensive position is warranted to help preserve capital, a Fund may without limit temporarily retain cash, or invest in prime commercial paper, high-grade debt securities, securities of the U.S. Government and its agencies and instrumentalities, and high-quality money market instruments, including repurchase agreements. When a Fund assumes a temporary defensive position, it is not invested in securities designed to achieve its investment objective.

Non-Diversified

The Oregon Intermediate Municipal Bond Fund and the Technology Fund are "non-diversified," which means that they may invest a greater percentage of their assets in the securities of a single issuer than the other Funds. Non-diversified funds are more susceptible to risks associated with a single economic, political, or regulatory occurrence than a more diversified portfolio might be. Some of those issuers also may present substantial credit or other risks. Similarly, the Oregon Intermediate Municipal Bond Fund may be more sensitive to adverse economic, business or political developments in the State of Oregon and also if it invests a substantial portion of its assets in the bonds of similar projects.

INVESTMENT RESTRICTIONS

The Prospectus sets forth the investment goals and principal investment strategies applicable to each Fund. The following is a list of investment restrictions applicable to each Fund. If a percentage limitation is adhered to at the time of an investment by a Fund, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of the restriction. Except as stated otherwise below, a Fund may not change these restrictions without the approval of a majority of its shareholders, which means the vote at any meeting of shareholders of a Fund of
(i) 67 percent or more of the shares present or represented by proxy at the meeting (if the holders of more than 50 percent of the outstanding shares are present or represented by proxy) or (ii) more than 50 percent of the outstanding shares, whichever is less.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended ("1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. With the exception of the Real Estate Fund, which will invest at least 65% of the value of its total assets in securities of companies principally engaged in the real estate industry, purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. With the exception of the Oregon Intermediate Municipal Bond Fund and the Technology Fund, purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

      INVESTMENT COMPANIES:


* Includes the value of compensation payable under the deferred compensation plan for independent Trustees of the Fund Complex that is determined as if the amounts deferred had been invested, as of the date of deferral, in shares of one or more funds in the Fund Complex as specified by Ms. Verville.

As of December 31, 2004, none of the disinterested directors or nominees or members of their immediate families owned any securities of the Advisor or any other entity directly or indirectly controlling, controlled by, or under common control with the Advisor.

Approval of Investment Advisory Contract

Each of the Funds has entered into an investment advisory contract with the Advisor. Each investment advisory contract is subject to annual approval of the Board of Directors, including a majority of disinterested directors. The existing contracts for the Funds were considered and approved at in-person meetings of the Funds' Boards of Directors held on October 12, 2005. In determining the reasonableness of the advisory fees under each of the contracts, the directors considered several factors, including:

- The nature and quality of services provided to the Funds' shareholders,

- The profitability of the advisory contract for the Advisor,

- Fall-out benefits realized by the Advisor from services as advisor to the Funds,

- A comparison of fee structures with other mutual funds, and

- The existence of economies of scale with respect to the provision of investment advice to the Funds.

In reviewing the quality of services provided by the Advisor, the directors reviewed the performance and expense rankings of the Funds as compared to their peers, based upon information compiled by Lipper, Inc. The directors reviewed the following information: (1) total expense rankings within each Fund's expense group, (2) actual management fee rankings of each Fund within its expense group,
(3) contractual management fee rankings of each Fund within its expense group and (4) performance rankings within each Fund's peer universe for the one-, three-, five- and ten-year periods. In addition, the directors reviewed data for each Fund comparing various return rankings of the Fund versus the Fund's actual management or total expense ranking. From this information, an overall Fund assessment ranking is made for each Fund. All of the Funds received a satisfactory ranking by the directors.

The directors also reviewed data related to the profitability of the Advisor with respect to its contract with each of the Funds. The directors considered the additional benefits to the Advisor as a result of its relationship with the Funds. The directors also considered the benefits to affiliates of the Advisor as the result of its management of the Funds.

After considering these and other factors, and each Fund's specific circumstances, the directors concluded that each Fund's advisory contract with the Advisor was reasonable for such Fund and in the best interests of its shareholders. During their deliberations, the directors requested from the Advisor all information reasonably necessary for the directors to evaluate each of the advisory contracts for the Funds. The disinterested directors were also assisted by, and met separately with, their independent counsel.

29

See the section entitled "INVESTMENT ADVISORY AND OTHER SERVICES PROVIDED BY AFFILIATES" for further information about the Advisor and each Fund's investment advisory contract.

Director Compensation:

The directors serve as directors/trustees of all open-end funds managed by the Advisor for which each director will receive an annual retainer of $45,000, an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the director fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The following table sets forth compensation earned by the Funds' directors for the fiscal year ended August 31, 2005. No officer of the Funds received any compensation from the Funds in 2005.

COMPENSATION

As of the Funds' most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Directors of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

The trading of other accounts could be used to benefit higher-fee accounts (front-running).

The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a

37

disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Directors have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

PROXY VOTING POLICY AND PROCEDURES

Each Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund.

The Advisor's policy is to vote all proxies for each client's securities in a manner considered by the Advisor to be in the best interest of its clients, including the Fund and its shareholders, without regard to any benefit to the Advisor or its affiliates. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, or its other clients or certain other persons. A member of the Proxy Committee is prohibited from voting on any proposal with respect to which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has three classes of proxy proposals. The first two classes are predetermined guidelines to vote for or against specific proposals, unless otherwise directed by the Proxy Committee. The third class is proposals requiring special consideration by the Proxy Committee. In addition, the Proxy Committee considers requests to vote on proposals in the first two classes other than according to the predetermined guidelines.

The Advisor generally votes in favor of proposals related to the following matters: selection of auditors (unless the auditor receives more than 50% of its revenues from non-audit activities from the company and its affiliates), election of directors (unless the proposal gives management the ability to alter the size of the board without shareholder approval), different persons for chairman of the board /chief executive officer (unless, in light of the size of the company and the nature of its shareholder base, the role of chairman and CEO should not be held by different persons), compensation (if provisions are consistent with standard business practices), debt limits (unless proposed specifically as an anti-takeover action), indemnification (unless for negligence and or breaches of fiduciary duty), meetings, name of company, principal office (unless the purpose is to reduce regulatory or financial supervision), reports and accounts (if the certifications required by the Sarbanes-Oxley Act of 2002 have been provided), par value, shares (unless proposed as an anti-takeover action), share repurchase programs, independent committees, and equal opportunity employment.

The Advisor generally votes against proposals related to the following matters: super majority voting, cumulative voting, preferred stock, warrants, rights, poison pills, reclassification of common stock and meetings held by written consent.

The Advisor gives the following matters special consideration: new proposals, proxies of investment company shares (other than election of directors, selection of accountants), mergers/acquisitions (proposals where a hostile merger/acquisition is apparent or where the Advisor represents ownership in more than one of the companies involved), shareholder proposals (other than those covered by the predetermined guidelines), executive/director compensation (other than those covered by the predetermined guidelines), pre-emptive rights, and proxies of international issuers which block securities sales between submission of a proxy and the meeting (proposals for these securities are voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with predetermined guidelines).

In addition, if a portfolio manager or other party involved with an Advisor client or a Fund account concludes that the interest of the client or the Fund requires that a proxy be voted on a proposal other than according to the predetermined guidelines, he or she may request that the Proxy Committee consider voting the proxy differently. If any person (or entity) requests the Proxy Committee (or any of its members) to vote a proxy other than according to a predetermined guideline, that person must furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's (or entity's) relationship with the party proposing the matter to shareholders or any other matter known to the person that would create a potential conflict of interest.

The Proxy Committee may vary from the predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted.

52

The Advisor's Proxy Committee is composed of operational and investment representatives of its regional offices as well as senior representatives of equity investments, equity research, compliance and legal. During the first quarter of each year, the Proxy Committee reviews all guidelines and establishes guidelines for expected new proposals. In addition to these reviews and its other responsibilities described above, the Proxy Committee's functions include annual review of it's the Advisor's Proxy Voting Policy and Procedures to ensure consistency with internal policies and regulatory agency policies, and to develop and modify voting guidelines and procedures as it deems appropriate or necessary.

The Advisor uses Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The actual voting records of the Funds relating to their portfolio securities during the 12-month period ended June 30, 2005 are available without charge, upon request, by calling 1-800-426-3750, or by accessing the SEC's website at http://www.sec.gov.

DISCLOSURE OF PORTFOLIO INFORMATION

The Board of Directors and Trustees of the Columbia funds have adopted policies with respect to the disclosure of the funds' portfolio holdings by the funds, the Advisor, or their affiliates. These policies provide that the Funds' portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Funds' policies are described below. The Directors/Trustees shall be updated as needed regarding the Funds' compliance with the policies, including information relating to any potential conflicts of interest between the interests of a Fund's shareholders and those of the Advisor and its affiliates. The Funds' policies prohibit the Advisor and the Funds' other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Funds' shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES

Each Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. Each Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of a Fund's fiscal year). Shareholders may obtain a Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, a Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF
TYPE OF FUND           INFORMATION PROVIDED     DISCLOSURE      DATE OF WEB POSTING

Equity Funds         Full portfolio holdings   Monthly        30 calendar days after
                     information.                             month-end.

Fixed Income Funds   Full portfolio holdings   Quarterly      60 calendar days after
                     information.                             the quarter-end

The scope of the information provided relating to a Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Funds' distributor, Columbia Management Distributors, at 800-426-3750, One Financial Center, Boston, Massachusetts 02111-2621.

53

A Fund, the Advisor or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES

Each Fund's policies provide that non-public disclosures of a Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

Each Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to the Advisor and its affiliates, these service providers include any sub-custodians of the Fund's securities, the Fund's independent registered public accounting firm, legal counsel, and financial printer, currently Bowne, Inc., and the Funds' proxy voting service, currently ISS. These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Funds. A Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Funds' investment adviser may follow a strategy similar to that of a Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

INVESTMENT ADVISORY AND OTHER SERVICES PROVIDED BY AFFILIATES

Pursuant to the investment contract, the Advisor provides research, advice, and supervision with respect to investment matters and determines which securities to purchase or sell and what portion of the Fund's assets to invest.

The Advisor provides office space and pays all executive salaries and executive expenses of the Fund.

Columbia Management Services, Inc. ("CMS") acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for each Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. CMS has retained Boston Financial Data Services, Inc. to assist it in performing services for the Funds. Until November 1, 2005, each Fund paid CMS an annual charge per open account as follows:

Equity Funds         $28.00
Fixed Income Funds   $34.00
Money Market Funds   $33.50

plus certain reimbursable out-of-pocket expenses as set forth in its agreement with CMS. There is no minimum aggregate fee payable by any Fund to CMS for transfer agent services. For certain classes of certain Funds, CMS has agreed to waive transfer agency fees in amounts and for periods more fully described in the relevant prospectus. Effective November 1, 2005, each Fund has entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to the Fund (and will continue to retain Boston Financial Data Services, Inc. to assist it) for a reduced fee. The new fee is $15.23 per account per annum, payable monthly. In addition, each Fund may pay CMS the fees and expenses it pays to third- party dealer firms that maintain omnibus accounts with the Fund, subject to a cap equal to 0.11% of the Fund's net assets represented by the account. Each Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Fund. The transfer agent fees paid to CMS for the fiscal year ended August 31, 2005 under each transfer agent agreement were $831,320 for the Mid Cap Growth Fund, $434,412 for the Small Cap Growth Fund I, $1,058,396 for the Real Estate Fund, $149,540 for the Technology Fund, $633,868 for the Strategic Investor Fund, $631,898 for the Balanced Fund, $238,988 for the Oregon Intermediate Municipal Bond Fund and $1,593,866 for the Conservative High Yield Fund. The transfer agent fees paid by the Mid Cap Growth Fund and Strategic Investor Fund are net of transfer agent fees waived by CMD.

Until November 1, 2005, the Advisor performed certain pricing, bookkeeping and administrative services for the Funds pursuant to a Pricing, Bookkeeping and Fund Administration Agreement (the "Agreement"). Under the terms of the Agreement, the Advisor (a) provided fund accounting and financial reporting oversight of State Street Bank & Trust Company, who provided the daily fund accounting and financial reporting services; (b) maintained and preserved in a secure manner the accounting records of the Funds; (c) provided fund administration, including daily prospectus, investment restrictions and 1940 Act compliance review, tax and distribution management, expense budgeting, performance reporting and statistical analysis, and board reporting; and (d) provided disaster planning. For the services rendered by the Advisor, each Fund agreed to pay a minimum of $25,000 plus two basis points for fund accounting and

55

$19,965 for financial reporting, with a maximum combined fee of $150,000. The Advisor was also entitled to be compensated for certain out-of-pocket expenses. The amount paid under this agreement by each of the Funds during the Funds' fiscal year ended August 31, 2005 was $161,452 for the Mid Cap Growth Fund, $113,870 for the Small Cap Growth Fund I, $159,371 for the Real Estate Equity Fund, $62,214 for the Technology Fund, $166,411 for the Strategic Investor Fund, $155,497 for the Balanced Fund, $170,288 for the Oregon Intermediate Municipal Bond Fund and $179,701 for the Conservative High Yield Fund.

Effective November 1, 2005, the Funds entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, each Fund will continue to receive substantially the same pricing, bookkeeping and administrative services as it currently receives under the Agreement. The Advisor and State Street Bank & Trust Company will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, each Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus 0.015% of the Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. For services provided under the Administrative Agreement, each Fund will pay the Advisor an annual fee equal to $0. Each Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

The Advisor and CMS are wholly owned subsidiaries of Columbia Management Group, LLC. CMD is a wholly owned subsidiary of the Advisor. Bank of America and its affiliates provide a wide range of banking, financial, and investment products and services to individuals and businesses. Their principal activities include customer and commercial banking, mortgage lending and servicing, trust administration, investment management, retirement plan services, brokerage and clearing services, securities underwriting, private and corporate financing and advisory activities, and insurance services.

PORTFOLIO TRANSACTIONS

Each Fund, other than the Strategic Investor Fund, will not generally invest in securities for short-term capital appreciation but, when business and economic conditions, market prices, or the Fund's investment policy warrant, individual security positions may be sold without regard to the length of time they have been held. This may result in a higher portfolio turnover rate and increase a Fund's transaction costs, including brokerage commissions. To the extent short-term trades result in gains on securities held less than one year, shareholders will be subject to taxes at ordinary income rates. See "TAXES" in this Statement of Additional Information.

The Funds may purchase their portfolio securities through a securities broker and pay the broker a commission, or they may purchase the securities directly from a dealer which acts as principal and sells securities directly for its own account without charging a commission. The purchase price of securities purchased from dealers serving as market makers will include the spread between the bid and asked prices. The Funds may also purchase securities from underwriters, the price of which will include a commission or discount paid by the issuer to the underwriter. There is generally no stated commission in the case of fixed income securities that are traded in the over-the-counter market, but the price paid by a Fund usually includes an undisclosed dealer commission or mark-up.

Prompt execution of orders at the most favorable price will be the primary consideration of the Funds in transactions where fees or commissions are involved. Additional factors considered by the Advisor in selecting brokers to execute a transaction include the: (i) professional capability of the executing broker and the value and quality of the brokerage services provided; (ii) size and type of transaction; (iii) timing of transaction in the context of market prices and trends; (iv) nature and character of markets for the security to be purchased or sold; (v) the broker's execution efficiency and settlement capability; (vi) the broker's experience and financial stability and the execution services it renders to the Advisor on a continuing basis; and (vii) reasonableness of commission. The Funds recently adopted policies prohibiting a Fund from directing commissions to any broker-dealer for sale of the Fund's shares.

Research, statistical, and other services offered by the broker also may be taken into consideration in selecting broker-dealers. These services may include: advice concerning the value of securities, the advisability of investing in, purchasing, or selling securities, and the availability of securities or the purchasers or sellers of securities; and furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategies, and performance of accounts. A commission in excess of the amount of a commission another broker or dealer would have charged for effecting a transaction may be paid by a Fund if the Advisor determines in good faith that the commission is reasonable in relation to the value of the brokerage and research services provided, viewed in terms of either that particular transaction or management's overall responsibilities with respect to the Fund.

The Advisor receives a significant amount of proprietary research from a number of brokerage firms, in most cases on an unsolicited basis. The Advisor does not make any commitments to allocate brokerage for proprietary research. The value of that research, however, is considered along with other factors in the selection of brokers. This research is considered supplemental to the Advisor's own internal research and does not, therefore, materially reduce the overall expenses incurred by the Advisor for its research. On a semi-annual basis, the Advisor's research analysts and portfolio managers participate in a detailed internal survey regarding the value of proprietary research and the skills or contributions made by the various brokerage analysts to the Advisor's investment process. Firms are then confidentially ranked based on that survey. Brokerage allocations are then made, as much as reasonably possible, based on those rankings.

The Advisor may use a Fund's commissions to acquire third party research or products that are not available through its full-service brokers. In these arrangements, the Advisor pays an executing broker a commission equal to the average rate paid on all other

61

trades and achieves what it believes is best execution on the trade. The executing broker then uses a portion of the commission to pay for a specific research service or product provided to the Advisor. Proposed research to be acquired in this manner must be approved by the Advisor's Soft Dollar Committee which is responsible for determining that the research provides appropriate assistance to the Advisor in connection with its investment management of the Funds and that the price paid with broker commissions is fair and reasonable.

The receipt of proprietary and third party research services or products from brokers or dealers might be useful to the Advisor and its affiliates in rendering investment management services to the Funds or other clients. Conversely, research provided by brokers or dealers who have executed orders on behalf of other clients of the Advisor and its affiliates might be useful to the Advisor in carrying out its obligations to a Fund.

Total brokerage commissions paid (agency only) by each of the respective Funds for each of the last three fiscal years were:

No agency brokerage commissions were paid by the Conservative High Yield Fund, d during the last three years. No agency brokerage commissions were paid by the Oregon Intermediate Municipal Bond Fund during 2003 or 2004.

Provided each Fund's Board of Directors is satisfied that the Fund is receiving the most favorable price and execution available, the Advisor may consider the sale of the Fund's shares as a factor in the selection of brokerage firms to execute its portfolio transactions. The placement of portfolio transactions with brokerage firms who sell shares of a Fund is subject to rules adopted by the National Association of Securities Dealers, Inc. The Advisor may use research services provided by and allocate purchase and sale orders for portfolio securities to certain financial institutions, including, to the extent permitted by law or order of the SEC, financial institutions that are affiliated with the Advisor, if the Advisor believes that the quality of the transaction and the commission are comparable to what they would be with other qualified brokerage firms. During the years listed, the Funds periodically used Fleet Institutional Trading, an affiliated broker-dealer of the Advisor that was disbanded in 2004, to execute purchase and sale orders. During 2004 and 2005, the Funds periodically used W.R. Hambrecht, an affiliated broker-dealer of the Advisor, to execute purchase and sale orders. During 2005, the Funds periodically used Bank of America Securities, an affiliated broker dealer of the Advisor, to execute purchase and sale orders.

The aggregate dollar amount of brokerage commissions paid to Fleet Institutional Trading for fiscal year 2004 is as follows:

FUND                       2004
----                      ------
Balanced Fund             $    0
Strategic Investor Fund   $5,125

The aggregate dollar amount of brokerage commissions paid to W.R. Hambrecht for the fiscal year 2004 is as follows:

FUND                        2004
----                      -------
Small Cap Growth Fund I   $ 1,365
Mid Cap Growth Fund       $ 9,785
Growth Fund               $25,250
Strategic Investor Fund   $ 1,500

The Funds paid no brokerage commissions to W.R. Hambrecht or Bank of America Securities in fiscal year 2005.

For all years, the aggregate dollar amount of purchase and sale transactions and total broker commissions were less than 1% of each Fund's total purchase and sale transactions and broker commissions. In addition to agency transactions, the Funds may purchase securities from an underwriting syndicate in which an affiliate is a member of the underwriting syndicate. Such trades will be executed in accordance with the rules and regulations of the 1940 Act, as well as procedures adopted by the Funds.

Buy and sell orders of a Fund may be aggregated by the Advisor with other trades made at the regional trading desk at which the trade is completed with those of other Funds or accounts or other investment pools managed by the Advisor or affiliates of the Advisor to achieve best execution, and, on the average, lower brokerage commission costs. Orders are aggregated only if the Advisor, in the exercise of its investment discretion, believes such aggregation is consistent with its duty to seek best execution and if each client involved in the order is treated fairly and on an equitable basis. Each client that participates in an aggregated order will typically participate at the average share price for all transactions in that order, with all transaction costs shared on a pro rata basis. Absent unusual circumstances, an aggregated order that is only partially completed by the Advisor will be allocated to each client on a pro rata basis based on the percentage of the combined order actually filled. Notwithstanding the above, the Advisor may execute buy and sell orders for clients and take action in performance of its duties with respect to any of its clients that may differ from actions taken with respect to another client with similar investment policies and objectives, so long as the Advisor shall, to the extent practical, allocate investment opportunities to clients over a period of time on a fair and equitable basis and in accordance with applicable law.

Allocations among accounts managed by the Advisor of investments in initial and secondary public offerings ("IPOs and "SPOs," jointly "POs") are made pursuant to Guidelines (the "Guidelines") established by the Advisor. The Guidelines establish which accounts are eligible to participate in a particular PO and what level of participation is permitted. After eligible accounts are identified, each manager receives, on behalf of his or her accounts, a pro rata share of such allocation. The allocation by the manager among his or her accounts is further divided among such accounts on a pro rata basis. A manager may decline to participate in an offering, or may elect to not have all accounts participate, even if his or her accounts are eligible to participate pursuant to the guidelines if he or she believes that the PO is not appropriate for his or her accounts or an individual account. A manager who declines to participate must document the basis of his or her decision not to participate. Over time, allocations to eligible accounts for which an PO opportunity is appropriate will be made on a fair and equitable basis.

The Advisor, CMD and the Funds maintain a Code of Ethics pursuant to Rule 17j-1 under the 1940 Act (the "Ethics Code") that sets forth general and specific standards relating to the securities trading activities of all their employees. The Ethics Code does not prohibit employees from purchasing securities that may be purchased or held by the Funds, but is intended to ensure that all employees conduct their personal transactions in a manner that does not interfere with the portfolio transactions of the Funds or the Advisor's other clients or take unfair advantage of their relationship with the Advisor. The specific standards in the Ethics Code include, among others, a requirement that trades of all access persons be pre-cleared; a prohibition on investing in initial public offerings; required pre-approval of an investment in private placements; a prohibition on portfolio managers trading in a security five business days before or after a trade in the same security by an account over which the manager exercises investment discretion; and a prohibition on realizing any profit on the trading of a security held less than 60 days. Certain securities and transactions, such as U.S. Treasuries and purchases of options on securities indexes or securities under an automatic dividend reinvestment plan, are exempt from the restrictions in the Ethics Code because they present little or no potential for abuse. In addition to the trading restrictions, the Ethics Code contains reporting obligations that are designed to ensure compliance and allow the Advisor's Ethics Committee to monitor that compliance.

The Advisor and the Funds have also adopted an Insider Trading Policy. The Insider Trading Policy prohibits any employee from trading, either personally or on behalf of others (including a client account), on the basis of material nonpublic information. All employees are required to certify each year that they have read and complied with the provisions of the Ethics Code and the Insider Trading Policy.

CAPITAL STOCK AND OTHER SECURITIES

Each Fund is an Oregon corporation and was organized in the year set forth below opposite its name.

FUND                                      DATE
----                                      ----

Oregon Intermediate Municipal Bond Fund   1984
Conservative High Yield Fund              1993

Each Fund offers some or all of the following classes of shares pursuant to a Rule 18f-3 Plan (the "Plan") adopted by the Directors in accordance with the 1940 Act: Class A, B, C, D, G, T and Z. Shares of each class of a Fund represent an equal pro rata interest in the Fund and, generally, have identical voting, dividend, liquidation, and other relative rights, preferences, limitations, and terms and conditions, except that: (1) each class has a different designation,
(2) each class of shares bears any expenses attributable to a class as set forth in the Plan and the relevant Prospectus, (3) each class has exclusive voting rights on any matter submitted to shareholders that relates solely to it or its distribution and service plan adopted under Rule 12b-1, if any, and (4) each class has separate voting rights on any matter submitted to shareholders in which the interests of one class differ from the interests of any other class. In addition, each class has the particular features described below. The differences among the classes of the Funds are subject to change by action of the Board of Directors of each Fund and to the extent permitted by the 1940 Act and each Fund's articles of incorporation and bylaws. All issued and outstanding shares of a Fund are fully paid and nonassessable. Shares have no preemptive rights. Fractional shares have the same rights proportionately as full shares. The shares of a Fund do not have cumulative voting rights, which means that the holders of more than 50 percent of the shares of the Fund, voting for the election of directors, can elect all the directors.

Except as indicated in Appendix I, Class G shares of a Fund automatically convert into Class T shares of the same Fund after eight years. Class B shares automatically convert into Class A shares of the same Fund at the time disclosed in the relevant Fund's Prospectus for Class A, B, C and D shares.

Shares of Class A, D and T shares are offered with a front-end sales charge, payable at the time of purchase, unless waived as set forth in the Prospectus for such Fund. Class B, C and G shares are offered without a front-end sales charge, but are subject to a contingent deferred sales charge depending on the length of time the shares are held. Class A, C, D and T shares held for fewer than 12 months after purchase are subject to a 1.00% contingent deferred sales charge. A detailed description of these various sales charges can be found in the Prospectus for the relevant class. Class T shares received in connection with a fund merger are subject to a contingent deferred sales charge if redeemed within 12 months of the original purchase.

Any reference to the phrase "vote of a majority of the outstanding voting securities of the Fund" means the vote at any meeting of shareholders of a Fund of (i) 67 percent or more of the shares present or represented by proxy at the meeting, if the holders of more than 50 percent of the outstanding shares are present or represented by proxy, or (ii) more than 50 percent of the outstanding shares, whichever is less.

DISTRIBUTION AND SERVICING

RULE 12B-1 DISTRIBUTION PLAN

The Directors have approved a plan pursuant to Rule 12b-1 under the 1940 Act (the "12b-1 Plan") for the Funds' Class A, B, C, D and G shares. Under the 12b-1 Plan, each Fund pays CMD a monthly service fee at an annual rate of up to 0.25% of the Fund's net assets attributed to Class A, B, C and D shares. Each Fund (other than Small Cap Growth Fund I) may also pay CMD monthly a distribution fee at an annual rate of 0.10% of the Fund's daily net assets attributed to Class A shares, and each Fund may pay up to 0.75% of the Fund's average daily net assets attributable to Class B, C and D shares. The Funds' Board of Directors currently limits payments under the 12b-1 Plan for Class A shares (for all Funds other than Small Cap Growth Fund I) to 0.25% annually. Also under the 12b-1 Plan, the Mid Cap Growth Fund pays CMD a monthly service fee at an annual rate of up to 0.50% of the Fund's net assets attributed to Class G shares, made up of up to 0.25% for certain shareholder services ("Shareholder Liaison Services") and up to 0.25% for administrative services ("Administrative Support Services"). The Mid Cap Growth Fund also pays CMD monthly a distribution fee at an annual rate of up to 0.65% of the Fund's average daily net assets attributed to Class G shares.

For the Oregon Intermediate Municipal Bond Fund, CMD has voluntarily agreed to waive a portion of its Class C and Class D distribution fees so that these fees do not exceed 0.65% annually of Class C's and Class D's average daily net assets. For the High Yield Fund, the Distributor has voluntarily agreed to waive a portion of its Class C and Class D distribution fees so that these fees do not exceed 0.85% annually of the Class C's and Class D's average daily net assets.

The monthly service and distribution fees shall be used by CMD to cover expenses and activities primarily intended to result in the sale of Fund shares. These expenses and activities may include but are not limited to: (a) direct out-of-pocket promotional expenses incurred by CMD in advertising and marketing Fund shares; (b) expenses incurred in connection with preparing, printing, mailing, and distributing or publishing advertisements and sales literature; (c) expenses incurred in connection with printing and mailing prospectuses and Statements of Additional Information to other than current shareholders; (d) periodic payments or commissions to one or more securities dealers, brokers, financial institutions and other industry professionals ("Service Organizations") with respect to the Funds' shares beneficially owned by customers for whom the Service Organization is the shareholder of record; (e) the direct and indirect cost of financing the payments or expenses included in
(a) and (d) above; or (f) such other services as may be construed by any court or governmental agency or commission, including the SEC, to constitute distribution services under the 1940 Act or rules and regulations thereunder.

Shareholder Liaison Services may include the following services provided by FSFs: (a) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (b) processing dividend payments; (c) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (d) providing periodic mailings to customers. Administrative Support Services may include the following services provided by FSFs: (a) providing customers with information as to their positions in Class G shares; (b) responding to customer inquiries; and (c) providing a service to invest the assets of customers in Class G shares.

CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to FSFs and for certain other purposes. Since the distribution and service fees are payable regardless of CMD's expenses, CMD may realize a profit from the fees. The 12b-1 Plan authorizes the Advisor to make payments out of its own funds for distribution or services costs.

At this time, the total Class G service and distribution fees have been limited to 0.95% for the Mid Cap Growth Fund. These limitations may be modified or terminated by the Board of Directors at any time.

SHAREHOLDER SERVICES PLAN

The Board of Directors has approved a Shareholder Services Plan (the "Services Plan") for Class T shares of the Mid Cap Growth Fund. Under the Services Plan, the Fund may pay FSFs a monthly service fee up to an annual rate of 0.50% of the Fund's net assets attributed to Class T shares beneficially owned by the customers of the FSFs, made up of 0.25% for Shareholder Liaison Services and 0.25% for Administrative Support Services, to compensate FSFs for providing services to beneficial owners of Class T shares. At this time, the fees payable by the holders of Class T shares pursuant to the Services Plan have been limited to 0.30% for the Mid Cap Growth Fund. The Services Plan provides that the FSFs will waive the fees to the extent that net investment income attributable to Class T shares earned in the applicable period is less than the fees due for such period.

TERMS OF THE 12B-1 AND SERVICES PLAN

CMD has advised the Funds that the 12b-1 Plan and the Services Plan could be significant factors in the growth and retention of the Funds' assets, resulting in a more advantageous expense ratio, increased investment flexibility and a greater ability to attract and retain research and portfolio management talent, which could benefit each class of the Funds' shareholders. The 12b-1 Plan and the Services Plan will continue in effect from year to year so long as their continuance is specifically approved at least annually by a vote of the Directors, including the Directors who are not interested persons of a Fund and have no direct or indirect financial interest in the operation of the 12b-1 Plan or the Services Plan or in any related agreements ("Independent Directors"), and, with respect to the 12b-1 Plan, cast in person at a meeting called for the purpose. All material amendments of the 12b-1 Plan or the Services Plan must be approved by the Directors in the manner provided in the foregoing sentence. The 12b-1 Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares. The 12b-1 Plan and the Services Plan may be terminated at any time by vote of a majority of the Independent Directors or, with respect to the 12b-1 Plan, by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the 12b-1 Plan and the Services Plan will only be effective if the selection and nomination of the Directors who are not interested persons of the Funds is effected by such Independent Directors.

The Funds' 12b-1 Plan monthly service and distribution fees paid to CMD for the period ended August 31, 2005 were:

PURCHASE, REDEMPTION AND PRICING OF SHARES

PURCHASES AND REDEMPTIONS

A detailed discussion of how you may purchase, redeem and exchange each class of shares in a Fund is discussed in the Prospectus applicable to such class. The following information and policies are supplemental to that found in the applicable Prospectus.

Each Fund will generally accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to a Fund before the Fund processes that day's transactions. If the FSF fails to transmit before a Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the New York Stock Exchange ("Exchange") on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of a Fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank. Investors should understand that, since the offering price of each Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

Each Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of a Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gifts checks, credit card convenience checks, credit cards, cash and bank counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described in the Prospectus. Certificates will not be issued. Shareholders may send any certificates to CMS for deposit to their account.

In addition to the commissions specified in a Fund's prospectus and this Statement of Additional Information, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

Preauthorized monthly electronic funds transfers for a fixed amount of at least $50 ($25 for Individual Retirement Accounts ("IRAs")) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds from the transfer. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING. The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any mutual fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your Fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same class of shares by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes. You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of Funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Funds Services, Inc. P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

TAX-SHELTERED RETIREMENT PLANS. CMD offers prototype tax-qualified plans, including Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company serves as Trustee of CMD prototype plans and charges a $20 annual fee. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in non-CMD prototype Retirement Plans (other than IRAs) also are charged a $20 annual fee unless the plan maintains an omnibus account with CMS. Participants in CMD prototype Plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a CMD IRA Rollover account in any Fund, or if the Plan maintains an omnibus account.

71

Consultation with a competent financial and tax advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification number available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800- 345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by
CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at NAV to the following individuals, whether currently employed or retired: Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of FSF's (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds

spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at (NAV) will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with

73

CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares). CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

74

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit- sharing or other employee benefit plans established under
Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may also be sold on any day the Exchange is open, either directly to a Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, a Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to a Fund, send a signed letter of instruction or stock power form to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable CDSC) next calculated after a Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may required for sales by corporations, agents, fiduciaries, surviving joint owners and individual retirement account holders and other legal entities. Call CMS for more information at 1-800-345-6611.

FSFs must receive requests before the time at which a Fund's shares are valued to receive that day's price. FSFs are responsible for furnishing all necessary documentation to CMS and may charge for this service.

75

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals from Class B, Class C and Class D shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their Class B, Class C and Class D share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of duplicative sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of a Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by a Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in street name must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-345-6611 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00 p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account, or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address and account number. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions may apply to retirement plan accounts.

NON CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, the Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

DISTRIBUTIONS

Distributions are invested in additional shares of the same class of a Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional

76

shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by CMS is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of Funds that pay daily dividends (Oregon Intermediate Municipal Bond Fund, and Conservative High Yield Fund) will be earned starting the day after the Fund receives payments for the shares.

HOW TO EXCHANGE SHARES

Shares of a Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) distributed by CMD on the basis of the NAVs per share at the time of exchange. Class D shares may be exchanged for Class C shares. Class Z shares may be exchanged for Class A shares of the other funds that are not offering Class Z shares. Class G shares can be exchanged for Class B shares, but once exchanged into Class B cannot be reexchanged back into Class G. Class T shares can be exchanged for Class A shares, but once exchanged into Class A cannot be reexchanged back into Class T. The prospectus of each Fund describes its investment objective and policies, and shareholders should obtain a prospectus and consider these objectives and policies carefully before requesting an exchange. Shares of certain of these funds are not available to residents of all states. Consult CMS before requesting an exchange.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

The Funds also reserve the right to close a shareholder account if the shareholder's actions are deemed to be detrimental to the Fund or its shareholders, including, without limitation, violating the exchange policy set forth in its Prospectus. If a Fund redeems shares, payment will be made promptly at the current net asset value. A redemption may result in a realized capital gain or loss.

PRICING OF SHARES

The net asset value ("NAV") per share of each Fund is determined by the Advisor, under procedures approved by the directors, as of the close of regular trading (normally 4:00 p.m. New York time) on each day the NYSE is open for business and at other times determined by the directors. The NAV per share is computed by dividing the value of all assets of the Fund, less its liabilities, by the number of shares outstanding.

A Fund may suspend the determination of the NAV of a Fund and the right of redemption for any period (1) when the NYSE is closed, other than customary weekend and holiday closings, (2) when trading on the NYSE is restricted, (3) when an emergency exists as a result of which sale of securities owned by the Fund is not reasonably practicable or it is not reasonably practicable for the Fund to determine the value of the Fund's assets, or (4) as the SEC may by order permit for the protection of security holders, provided the Fund complies with rules and regulations of the SEC, which govern as to whether the conditions prescribed in (2) or (3) exist. The NYSE observes the following holidays: New Year's Day, Martin Luther King, Jr.'s Birthday, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.

77

For purposes of calculating the NAV of a Fund's shares, the following procedures are utilized whenever applicable. Each Fund's equity securities are valued at the last sale price on the securities exchange or national securities markets at which such securities primarily are traded. Securities not listed on an exchange or national securities market, or securities in which there were no transactions, are valued using the last bid price. Each Fund purchasing debt securities uses market value to value such securities as quoted by an independent pricing service, dealers who are market makers in the securities or by procedures and guidelines approved by the Funds' Board of Directors. Market values are generally based on the average of bid and ask prices, or by reference to other securities with comparable ratings, interest rates and maturities. Certain securities for which daily market quotations are not readily available, or for which the Advisor believes the quotations do not accurately value the security in question, may be fair valued by the Advisor, pursuant to guidelines established by the Funds' Board of Directors.

Temporary cash investments are carried at values deemed best to reflect their fair values as determined in good faith by the Advisor, under procedures adopted by the Funds' Board of Directors. These values are based on cost, adjusted for amortization of discount or premium and accrued interest, unless unusual circumstances indicate that another method of determining fair value should be used.

The value of assets or liabilities initially expressed in a foreign currency will, on a daily basis, be converted into U.S. dollars. Foreign securities will generally be valued based upon the most recent closing price on their principal exchange, or based upon the most recent price obtained by the Fund, if the security is not priced on an exchange, even if the close of that exchange or price determination is earlier than the time of the Funds' NAV calculation. In the case of such foreign security, if an event that is likely to affect materially the value of a portfolio security occurs between the time the foreign price is determined and the time the Fund's NAV is calculated, it may be necessary to value the security in light of that event.

CUSTODIAN

State Street Bank & Trust Company (the "Custodian"), 2 Avenue de Lafayette, Boston, Massachusetts 02111-2900 acts as the Funds' general custodian, for both domestic and foreign securities. The Custodian holds securities and cash of the Funds, receives and pays for securities purchased, delivers against payment securities sold, receives and collects income from investments, makes all payments covering expenses of the Funds, and performs other administrative duties, all as directed by authorized officers of the Advisor. The Custodian does not exercise any supervisory function in the purchase and sale of portfolio securities or payment of dividends.

Portfolio securities purchased in the United States are maintained in the custody of the Custodian. Portfolio securities purchased outside the United States by the Funds are maintained in the custody of foreign banks, trust companies, or depositories that have sub-custodian arrangements with the Custodian (the "foreign sub-custodians"). Each of the domestic and foreign custodial institutions that may hold portfolio securities of the Funds has been approved by the Board of Directors of the Funds or, in the case of foreign securities, by the Custodian, as a delegate of the Board of Directors, all in accordance with regulations under the 1940 Act.

The Advisor determines whether it is in the best interest of the Funds and their shareholders to maintain a Fund's assets in each of the countries in which the Fund invests ("Prevailing Market Risk"). The review of Prevailing Market Risk includes an assessment of the risk of holding a Fund's assets in a country, including risks of expropriation or imposition of exchange controls. In evaluating the foreign sub-custodians, the Board of Directors, or its delegate, will review the operational capability and reliability of the foreign sub-custodian. With respect to foreign investments and the selection of foreign sub-custodians, however, there is no assurance that the Funds, and the value of their shares, will not be adversely affected by acts of foreign governments, financial or operational difficulties of the foreign sub-custodians, difficulties and cost of obtaining jurisdiction over, or enforcing judgments against, the foreign sub-custodians, or the application of foreign law to a Fund's foreign sub-custodial arrangement. Accordingly, an investor should recognize that the risks involved in holding assets abroad are greater than those associated with investing in the United States.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

PricewaterhouseCoopers LLP, located at 125 High Street, Boston, Massachusetts, 02110-1707 is the Fund's independent registered public accounting firm, providing audit and tax return review services and assistance and consultation, in connection with the review of various Securities and Exchange Commission filings. The annual financial statements incorporated by reference in this Statement of Additional Information have been so incorporated, and the financial highlights included in the Prospectuses have been so included, in reliance upon the report of PricewaterhouseCoopers LLP given on the authority of said firm as experts in accounting and auditing.

TAXES

FEDERAL INCOME TAXES

Each Fund intends and expects to meet continuously the tests for qualification as a regulated investment company under Part I of Subchapter M of the Code. Each Fund believes it satisfies the tests to qualify as a regulated investment company. If a Fund were to fail to qualify as a "regulated investment company" in any year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and distributions would generally be taxable as ordinary dividend income to the shareholders.

To qualify as a regulated investment company for any taxable year, each Fund must, among other things:

(a) derive at least 90 percent of its gross income from dividends; interest; payments with respect to securities loans; gains from the sale or other disposition of stock, securities, or foreign currencies; other income
(including but not limited to gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities, or currencies; or net income from an interest in qualified publicly traded partnerships (the "90 Percent Test"); and

(b) diversify its holdings so that, at the end of each quarter of its taxable year, (i) 50 percent or more of the value of the assets of the Fund consists of cash, government securities, securities of other regulated investment companies and other securities limited, in respect of any one issuer of such other securities, to an amount not greater than 5 percent of the value of the assets of the Fund and 10 percent of the outstanding voting securities of such issuer, and (ii) not more than 25 percent of the value of the assets of the Fund is invested in either the securities (other than government securities or securities of other regulated investment companies) of any one issuer or of two or more issuers that the Fund "controls" within the meaning of Section 851 of the Code and that meet certain requirements or the securities of one or more qualified publicly traded partnerships (the "Diversification Test"). In addition, a Fund must file, or have filed, a proper election with the Internal Revenue Service.

Part I of Subchapter M of the Code will apply to a Fund during a taxable year only if it meets certain additional requirements. Among other things, the Fund must: (a) have a deduction for dividends paid (without regard to capital gain dividends and exempt interest dividends) at least equal to the sum of 90 percent of its investment company taxable income (computed without any deduction for dividends paid) and 90 percent of its tax-exempt interest (net of expenses attributable to such interest), and (b) either (i) have been subject to Part I of Subchapter M for all taxable years ending on or after November 8, 1983 or
(ii) as of the close of the taxable year have no earnings and profits accumulated in any taxable year to which Part I of Subchapter M did not apply.

A regulated investment company that meets the requirements described above is taxed only on its "investment company taxable income," which generally equals the undistributed portion of its ordinary net income and any excess of net short-term capital gain over net long-term capital loss. In addition, any excess of net long-term capital gain over net short-term capital loss that is not distributed as a "capital gain dividend" is taxed to a Fund at corporate capital gain tax rates. The policy of each Fund is to apply capital loss carry-forwards as a deduction against future capital gains before making a capital gain distribution to shareholders. Under rules that are beyond the scope of this discussion, certain capital losses and certain net foreign currency losses resulting from transactions occurring in November and December of a taxable year may be taken into account either in that taxable year or in the following taxable year.

If any net capital gains (i.e. the excess of net long-term capital gains over net short-term capital losses) are retained by a Fund, requiring federal income taxes to be paid thereon by the Fund, the Fund may elect to treat such capital gains as having been distributed to shareholders. In the case of such an election, shareholders will be taxed on such amounts as long-term capital gains, will be able to claim their proportional share of the federal income taxes paid by the Fund on such gains as credits against their own federal income tax liabilities, and generally will be entitled to increase the adjusted tax basis of their shares in the Fund by the differences between their pro rata shares of such gains and their tax credits.

SPECIAL ASPECTS OF 90 PERCENT TEST WITH RESPECT TO FOREIGN CURRENCY. For purposes of the 90 Percent Test, foreign currency gains that are not directly related to a Fund's principal business of investing in stocks or securities (or options and futures with respect to stock or securities) may be excluded from qualifying income by regulation. No such regulations, however, have been issued.

Unless an exception applies, a Fund may be required to recognize some income with respect to foreign currency contracts under the mark-to-market rules of Section 1256 even though that income is not realized. Special rules under Sections 1256 and 988 of the Code determine the character of any income, gain, or loss on foreign currency contracts.

OREGON INTERMEDIATE MUNICIPAL BOND FUND. In certain cases, Subchapter M permits the character of tax-exempt interest received and distributed by a regulated investment company to flow through for federal tax purposes as tax-exempt interest to its shareholders, provided that 50 percent or more of the value of its assets at the end of each quarter is invested in tax-exempt assets such as municipal bonds. For purposes of this Statement of Additional Information, the term "municipal bonds" refers to obligations that pay interest that is tax-exempt under Section 103 of the Code. For purposes of this Statement of Additional Information, the term "tax-exempt interest" refers to interest that is not includable in gross income for federal income tax purposes. As discussed below, however, tax-exempt interest may result in an increase in the taxes of the recipient because of the alternative minimum tax, the environmental tax, the branch profits tax, or under other provisions of the Code that are beyond the scope of this Statement of Additional Information. The Oregon Intermediate Municipal Bond Fund intends to have at least 50 percent of the value of its total assets at the close of each quarter of their taxable year consist of obligations the interest on which is not includable in gross income for federal income tax purposes under Section 103 of the Code. As a result, the Oregon Intermediate Municipal Bond Fund's dividends payable from net tax-exempt interest earned from municipal bonds should qualify as exempt-interest dividends.

Distributions properly designated by the Oregon Intermediate Municipal Bond Fund as representing net tax-exempt interest received on municipal bonds (including municipal bonds of Guam, Puerto Rico, and certain other issuers) will not be includable by shareholders in gross income for federal income tax purposes (except for shareholders who are, or are related to, "substantial users," as discussed below). Distributions representing net taxable interest received by the Oregon Intermediate Municipal Bond Fund from sources other than municipal bonds, representing the excess of net short-term capital gain over net long-term capital loss, or representing taxable accrued market discount on the sale or redemption of municipal bonds, will be taxable to shareholders as ordinary income.

Any capital loss realized upon the redemption of shares of the Oregon Intermediate Municipal Bond Fund six months or less from the date of purchase of the shares and following receipt of an exempt-interest dividend will be disallowed to the extent of such exempt-interest dividend. Section 852(b)(4) of the Code contains special rules on the computation of a shareholder's holding period for this purpose.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long- term capital gains (generally subject to a maximum 15 percent tax rate for shareholders who are individuals) regardless of the length of time fund shares are held. As described below, as a result of 2003 legislation, qualified dividend income distributions to individual shareholders generally are taxed at the same rate that applies to long-term capital gains.

A tax-exempt fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of one year or more is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Interest on indebtedness incurred or continued by shareholders to purchase or carry shares of the Oregon Intermediate Municipal Bond Fund will not be deductible for federal income tax purposes. Under rules issued by the Internal Revenue Service, the purchase of such shares may be considered to have been made with borrowed funds even though the borrowed funds are not directly traceable to the purchase of shares. Special rules that are beyond the scope of this Statement of Additional Information limit the deduction of interest paid by financial institutions. Investors with questions regarding these issues should consult their tax advisors.

Dividends attributable to interest on certain private activity bonds issued after August 7, 1986 will be items of tax preference and must be included in alternative minimum taxable income for the purpose of determining liability, if any, for the 26-28 percent alternative minimum tax for individuals and the 20 percent alternative minimum tax for corporations. Furthermore, the alternative minimum taxable income for corporations includes an adjustment equal to 75 percent of the excess of "adjusted current earnings" over the corporation's other federal alternative minimum taxable income (computed without regard to "adjusted current earnings" and without regard to any "alternative tax net operating loss"). See Section 56(g) of the Code. For the purpose of alternative minimum tax for corporations, all exempt-interest dividends, less any interest expense incurred to purchase or carry shares paying exempt interest dividends, must be taken into account as "adjusted current earnings." In addition, exempt-interest dividends paid to corporate investors may be subject to tax under the environmental tax, which applies at the rate of 0.12 percent on the excess of the "modified alternative minimum taxable income" of the corporation over $2 million. See Section 59A of the Code.

In some cases, exempt-interest dividends paid by the Oregon Intermediate Municipal Bond Fund may indirectly affect the amount of Social Security benefits or railroad retirement benefits that are taxable income to an investor. See
Section 86 of the Code.

80

Certain foreign corporations may be subject to the "branch profits tax" under Section 884 of the Code. The receipt of dividends from the Oregon Intermediate Municipal Bond Fund may increase the liability of the foreign corporation under the branch profits tax, even if such dividends are generally tax-exempt.

"Substantial users" (or persons related thereto) of facilities financed by certain governmental obligations are not allowed to exclude from gross income interest on such obligations. "Substantial user" is defined under U.S. Treasury Regulations to include a non- exempt person (i) who regularly uses a part of such facilities in his or her trade or business and whose gross revenues derived with respect to the facilities financed by the issuance of bonds are more than 5 percent of the total revenues derived by all users of such facilities, (ii) who occupies more than 5 percent of the usable area of such facilities or (iii) for whom such facilities or a part thereof were specifically constructed, reconstructed or acquired. "Related persons" include certain related natural persons, affiliated corporations, a partnership and its partners, and an S corporation and its shareholders. No investigation as to the substantial users of the facilities financed by bonds in the Oregon Intermediate Municipal Bond Fund's portfolios will be made by the Oregon Intermediate Municipal Bond Fund. Potential investors who may be, or may be related to, substantial users of such facilities should consult their tax advisors before purchasing shares of the Oregon Intermediate Municipal Bond Fund.

At the respective times of issuance of the municipal bonds, opinions relating to the validity thereof and to the exemption of interest thereon from federal income tax generally were or will be rendered by bond counsel engaged by the respective issuing authorities. The Oregon Intermediate Municipal Bond Fund will not make any review of the issuance of the municipal bonds or of the basis for such opinions. An opinion concerning tax-exempt interest generally assumes continuing compliance with applicable standards and restrictions. Certain circumstances or actions by an issuer after the date of issuance can cause interest on municipal bonds to become includable in gross income. In some cases, the interest on such bonds could become taxable from the date of issuance. The Oregon Intermediate Municipal Bond Fund will not monitor any issuers or any municipal bonds to attempt to ensure that the interest remains tax-exempt.

If the Oregon Intermediate Municipal Bond Fund declares dividends attributable to taxable interest it has received, it intends to designate as taxable the same percentage of the day's dividend that the actual taxable income earned on that day bears to total income earned on that day. Thus, the percentage of the dividend designated as taxable, if any, may vary from day to day.

Shares of the Oregon Intermediate Municipal Bond Fund generally would not be a suitable investment for a tax-exempt institution, a tax-exempt retirement plan, or an individual retirement account. To the extent that such an entity or account is tax-exempt, no additional benefit would result from receiving tax-exempt dividends.

From time to time, proposals have been introduced before Congress to restrict or eliminate the federal income tax exemption for interest on municipal bonds. Similar proposals may be introduced in the future. If such a proposal were enacted, the availability of municipal bonds for investment by the Oregon Intermediate Municipal Bond Fund and the value of portfolio securities held by the the Fund would be affected.

HEDGING TRANSACTIONS. If a Fund engages in hedging transactions, including hedging transactions in options, futures contracts, and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale, and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. Each Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of each Fund.

Certain of a Fund's hedging activities (including its transactions, if any, in foreign currencies or foreign currency-denominated instruments) are likely to produce a difference between its book income and its taxable income (or, with respect to a tax-exempt Fund, the sum of its net tax-exempt and taxable income). If a Fund's book income exceeds its taxable income (or, with respect to a tax-exempt Fund, its tax-exempt income), the distribution (if any) of such excess will be treated as (i) a dividend to the extent of the Fund's remaining earnings and profits (including earnings and profits arising from tax-exempt income), (ii) thereafter as a return of capital to the extent of the recipient's basis in the shares, and (iii) thereafter as gain from the sale or exchange of a capital asset. If a Fund's book income is less than its taxable income (or, for a tax-exempt Fund, the sum of its net tax-exempt and taxable income), the Fund could be required to make distributions exceeding book income to qualify as a regulated investment company that is accorded special tax treatment.

OTHER FUNDS. Shareholders of Funds other than the Oregon Intermediate Municipal Bond Fund are taxed on distributions of net investment income, or of any excess of net short-term capital gain over net long-term capital loss, as ordinary income. Income distributions to corporate shareholders from the Strategic Investor Fund, the Mid Cap Growth Fund, and the Balanced Fund may qualify, in whole or part, for the federal income tax dividends-received deduction, depending on the amount of qualifying dividends received by the Fund. Qualifying dividends may include those paid to a Fund by domestic corporations but do not include those paid by foreign corporations. The dividends-received deduction equals 70 percent of qualifying dividends received from a Fund by a shareholder, and is subject to a

81

holding period requirement. In addition, qualifying dividends are includable in adjusted current earnings for purposes of computing the corporate alternative minimum tax. However, distributions from the Conservative High Yield Fund are unlikely to so qualify because the income of this Fund consists largely or entirely of interest rather than dividends. In addition, to the extent the Real Estate Fund's income is derived from interest and distributions from real estate investment trusts ("REITs"), distributions from that Fund will not qualify for the dividends-received deduction. Distributions of any excess of net long-term capital gain over net short-term capital loss from a Fund are ineligible for the dividends-received deduction.

GENERAL CONSIDERATIONS. Distributions from a Fund (other than exempt-interest dividends) will be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions properly designated by any Fund as representing the excess of net long-term capital gain over net short-term capital loss are taxable to shareholders at the applicable long-term capital gains rate, regardless of the length of time the shares of the Fund have been held by shareholders. For noncorporate taxpayers, the highest rate that applies to long-term capital gains is lower than the highest rate that applies to ordinary income; however, as a result of 2003 legislation, for taxable years beginning on or before December 31, 2008 qualified dividend income distributions to individuals generally are taxed at the same rate that applies to long-term capital gains, subject to holding period requirements with respect to shareholders and the Funds as well as other requirements. For this purpose, long-term capital gain rates apply to the extent that the Fund receives dividends from domestic or qualifying foreign corporations and the Fund meets holding period and other requirements. Generally, a dividend received from a foreign corporation will not be treated as qualified dividend income if the foreign corporation is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company or, for taxable years of foreign corporations beginning on or before December 31, 2004, as a foreign personal holding company or a foreign investment company. If the aggregate qualified dividends received by a Fund during any taxable year are 95 percent or more of its gross income, then 100 percent of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss. Any loss that is realized and allowed on redemption of shares of the Fund six months or less from the date of purchase of the shares and following the receipt of a capital gain dividend will be treated as a long-term capital loss to the extent of the capital gain dividend. For this purpose, Section 852(b)(4) of the Code contains special rules on the computation of a shareholder's holding period.

Long term capital gains rates have been temporarily reduced, in general, to 15 percent, with lower rates applying to taxpayers in the 10-percent and 15-percent rate brackets for taxable years beginning on or before December 31, 2008.

The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares will be treated as long-term capital gain if the shares have been held for more than 12 months. Otherwise the gain on the sale, exchange or redemption of shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term capital loss if the shares have been held more than 12 months, and otherwise as a short-term capital loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly-purchased shares will be adjusted to reflect the disallowed loss.

A portion of the income distributions from the Real Estate Fund will include a tax return of capital because of the nature of the distributions received by the Fund from its holdings in REITs. A tax return of capital is a nontaxable distribution that reduces the tax cost basis of your shares in the Real Estate Fund. The effect of a return of capital is to defer your tax liability on that portion of your income distributions until you sell your shares of the Real Estate Fund. There is no recognition of gain or loss unless the return of capital exceeds the cost basis in the shares.

Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of capital. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses. A distribution may be taxable to a shareholder even if the distribution reduces the net asset value of the shares held below their cost (and is in an economic sense a return of the shareholder's capital). This tax result is most likely when shares are purchased shortly before an annual distribution of capital gains or other earnings.

Distributions of taxable net investment income and net realized capital gains will be taxable as described above, whether paid in shares or in cash. Each distribution is accompanied by a brief explanation of the form and character of the distribution. Within 60 days after the close of each calendar year, each Fund issues to each shareholder a statement of the federal income tax status of all distributions, including a statement of the prior calendar year's distributions which the Fund has designated to be treated as long-term capital gain and, in the case of the Oregon Intermediate Municipal Bond Fund, as tax-exempt interest, or in the case of the Real Estate Fund, as a tax return of

82

capital. The ratio of tax-exempt income to total net investment income earned during the year may be substantially different from the ratio of tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of tax-exempt income to total net investment income actually earned while a shareholder.

Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the federal AMT.

Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

Each Fund is generally required to obtain from its shareholders a certification of the shareholder's taxpayer identification number and certain other information. Each Fund generally will not accept an investment to establish a new account that does not comply with this requirement. With respect to amounts paid through 2010, if a shareholder fails to certify such number and other information, or upon receipt of certain notices from the Internal Revenue Service, the Fund may be required to withhold 28 percent of any reportable interest or dividends, or redemption proceeds, payable to the shareholder, and to remit such sum to the Internal Revenue Service, for credit toward the shareholder's federal income taxes. The backup withholding rate will be 31 percent for amounts paid after December 31, 2010. A shareholder's failure to provide a social security number or other tax identification number may subject the shareholder to a penalty of $50 imposed by the Internal Revenue Service. In addition, that failure may subject the Fund to a separate penalty of $50. This penalty will be charged against the shareholder's account, which will be closed. Closure of the account may result in a capital gain or loss.

If a Fund declares a dividend in October, November, or December payable to shareholders of record on a certain date in such a month and pays the dividend during January of the following year, the shareholders will be taxed as if they had received the dividend on December 31 of the year in which the dividend was declared. Thus, a shareholder may be taxed on the dividend in a taxable year prior to the year of actual receipt.

A special tax may apply to a Fund if it fails to make enough distributions during the calendar year. The required distributions for each calendar year generally equal the sum of (a) 98 percent of the ordinary income for the calendar year plus (b) 98 percent of the capital gain net income for the one-year period that ends on October 31 during the calendar year (or for the calendar year itself if the Fund so elects), plus (c) an adjustment relating to any shortfall for the prior taxable year. If the actual distributions are less than the required distributions, a tax of 4 percent applies to the shortfall.

The Code allows the deduction by certain individuals, trusts, and estates of "miscellaneous itemized deductions" only to the extent that such deductions exceed 2 percent of adjusted gross income. The limit on miscellaneous itemized deductions will not apply, however, with respect to the expenses incurred by any "publicly offered regulated investment company." Each Fund believes that it is a publicly offered regulated investment company because its shares are continuously offered pursuant to a public offering (within the meaning of
Section 4 of the Securities Act of 1933, as amended). Therefore, the limit on miscellaneous itemized deductions should not apply to expenses incurred by any of the Funds.

The Funds may purchase zero coupon bonds (or other discounted debt securities) and payment-in-kind ("PIK") bonds. With respect to zero coupon bonds, a Fund recognizes original-issue-discount income ratably over the life of the bond even though the Fund receives no payments on the bond until the bond matures. With respect to PIK bonds, a Fund recognizes interest income equal to the fair market value of the bonds distributed as interest. Because a Fund must distribute 90 percent of its income to remain qualified as a registered investment company, a Fund may be forced to liquidate a portion of its portfolio (possibly at a time when it is not advantageous to do so) to generate cash to distribute to its shareholders with respect to original-issue-discount income from zero coupon bonds and interest income from PIK bonds.

A Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned.

FOREIGN INCOME TAXES

The Mid Cap Growth Fund, the Small Cap Growth Fund I, the Real Estate Fund, the Technology Fund, the Strategic Investor Fund, the Balanced Fund, and the Conservative High Yield Fund may invest in the securities of foreign corporations and issuers. Foreign countries may impose income taxes, generally collected by withholding, on foreign-source dividends and interest paid to a Fund. These

83

foreign taxes will reduce a Fund's distributed income and a Fund's return. The Funds generally expect to incur, however, no foreign income taxes on gains from the sale of foreign securities.

The United States has entered into income tax treaties with many foreign countries to reduce or eliminate the foreign taxes on certain dividends and interest received from corporations in those countries. The Funds intend to take advantage of such treaties where possible. It is impossible to predict with certainty the effective rate of foreign taxes that will be paid by a Fund since the amount invested in particular countries will fluctuate and the amounts of dividends and interest relative to total income will fluctuate.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

INVESTMENT IN PASSIVE FOREIGN INVESTMENT COMPANIES. Investment by a Fund in certain "passive foreign investment companies" ("PFICs") could subject the Fund to a U.S. federal income tax (including interest charges) on distributions received from the company or on proceeds received from the disposition of shares in the company, which tax cannot be eliminated by making distributions to fund shareholders. However, the Fund may be able to elect to treat a PFIC as a "qualified electing fund," in which case the Fund will be required to include its share of the company's income and net capital gain annually, regardless of whether it receives any distribution from the company. Alternatively, the Fund may make an election to mark the gains (and, to a limited extent, losses) in such holdings "to the

84

market" as though it had sold and repurchased its holdings in those PFICs on the last day of the Fund's taxable year. Such gains and losses are treated as ordinary income and loss. The qualified electing fund and mark-to-market elections may have the effect of accelerating the recognition of income (without the receipt of cash) and increasing the amount required to be distributed for the Fund to avoid taxation. Making either of these elections therefore may require a Fund to liquidate other investments (including when it is not advantageous to do so) in order to meet its distribution requirement, which also may accelerate the recognition of gain and affect a Fund's total return. It is anticipated that any taxes on a Fund with respect to investments in PFICs would be insignificant.

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS

Dividends from the Real Estate Fund will generally not be treated as qualified dividend income.

The Real Estate Fund, and to a lesser extent certain other Funds (see "INVESTMENTS HELD AND INVESTMENT PRACTICES BY THE FUND"), may invest in REITs that hold residual interests in real estate mortgage investment conduits ("REMICs"). Under Treasury regulations that have not yet been issued, but may apply retroactively, a portion of the Real Estate Fund's income from a REIT that is attributable to the REIT's residual interest in a REMIC (referred to in the Code as an "excess inclusion") will be subject to federal income tax in all events. These regulations are also expected to provide that excess inclusion income of a regulated investment company, such as the Real Estate Fund, will be allocated to shareholders of the regulated investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest directly.

In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on unrelated business income, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign shareholder, will not qualify for any reduction in U.S. federal withholding tax. In addition, if at any time during any taxable year a "disqualified organization" (as defined in the Code) is a record holder of a share in a regulated investment company, then the regulated investment company will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the highest federal income tax rate imposed on corporations. The Real Estate Fund does not intend to invest in REITs, a substantial portion of the assets of which consists of residual interests in REMICs.

STATE INCOME TAXES

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their fund shares and distributions and redemption proceeds received from the Fund.

OREGON INTERMEDIATE MUNICIPAL BOND FUND. Individuals, trusts, and estates will not be subject to the Oregon personal income tax on distributions from the Oregon Intermediate Municipal Bond Fund that are derived from tax-exempt interest paid on the municipal bonds of Oregon and its political subdivisions and certain other issuers (including Puerto Rico and Guam). However, individuals, trusts, and estates that are subject to Oregon personal income tax generally are also subject to the Oregon personal income tax on distributions from the Oregon Intermediate Municipal Bond Fund that are derived from other types of income, including interest on the municipal bonds of states other than Oregon. Furthermore, it is expected that corporations subject to the Oregon corporation excise or income tax will be subject to that tax on income from the Oregon Intermediate Municipal Bond Fund, including income that is exempt for federal purposes. Shares of the Oregon Intermediate Municipal Bond Fund will not be subject to Oregon property tax. Additional discussion regarding local taxes, and the tax rules of states other than Oregon, are beyond the scope of this discussion.

Oregon generally taxes corporations on interest income from municipal bonds. The Oregon Intermediate Municipal Bond Fund is a corporation. However, ORS 317.309(2) provides that a regulated investment company may deduct from such interest income the exempt-interest dividends that are paid to shareholders. The Oregon Intermediate Municipal Bond Fund expects to distribute its interest income so that it will not be liable for Oregon corporation excise or income taxes.

The Oregon Intermediate Municipal Bond Fund will report annually to its shareholders the percentage and source, on a state-by-state basis, of interest income on municipal bonds received by the Fund during the preceding year.

GENERAL INFORMATION

Capital gains distributed to shareholders of the Oregon Intermediate Municipal Bond Fund will generally be subject to state and local taxes. Further discussion regarding the state and local tax consequences of investments in the Funds are beyond the scope of the tax discussions in the Prospectus and this Statement of Additional Information.

ADDITIONAL INFORMATION

The foregoing summary and the summary included in the Prospectus under "Distributions and Taxes" of tax consequences of investment in the Funds are necessarily general and abbreviated. No attempt has been made to present a complete or detailed explanation of tax matters. Furthermore, the provisions of the statutes and regulations on which they are based are subject to change, prospectively or retroactively, by legislative or administrative action. Local taxes are beyond the scope of this discussion. Prospective investors in the Funds are urged to consult their own tax advisors regarding specific questions as to federal, state, or local taxes.

Recent Tax Shelter Reporting Regulations. Under recently promulgated Treasury regulations, if a shareholder recognizes a loss under Section 165 of the Code with respect to shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

This discussion applies only to general U.S. shareholders. Foreign investors and U.S. shareholders with particular tax issues or statuses should consult their own tax advisors regarding the special rules that may apply to them.

SHAREHOLDER MEETINGS

The Funds are not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Funds have voluntarily undertaken to hold a shareholder meeting at which the Board of Directors would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Funds' By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Directors may fill any vacancies in the Board of Directors except that the Directors may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Directors then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Directors then in office have been elected to such office by the shareholders, the Directors must call a meeting of shareholders. Directors may be removed from office by a written consent signed by a majority of the outstanding shares of the Funds or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Directors shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Directors, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other Funds in the Fund Complex that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

FINANCIAL STATEMENTS

The Funds' most recent Annual and Semi-Annual Report to shareholders are separate documents supplied with this Statement of Additional Information. The financial statements, accompanying notes and report of independent registered public accounting firm appearing in the Annual Report, and the financial statements and accompanying notes appearing in the Semi-Annual Report are incorporated by reference into this Statement of Additional Information.

APPENDIX I

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

87

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have

88

interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

89

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

90

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

91

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

92

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

93

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence.

CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

94

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

- Potential competitiveness

- Current and potential returns

- Current and potential risk

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

99

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

DESCRIPTION OF THE FUND

The Fund is an open-end, management investment company. The Fund is diversified, which means that, with respect to 75 percent of its total assets, the Fund will not invest more than 5 percent of its assets in the securities of any single issuer. The investment advisor for the Fund is Columbia Management Advisors, LLC (the "Advisor" or "Columbia Advisors"). See the section entitled "INVESTMENT ADVISORY AND OTHER FEES PAID TO AFFILIATES" for further information about the Advisor.

It is expected that the Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

INVESTMENTS HELD AND INVESTMENT PRACTICES USED BY THE FUND

The Prospectus describes the fundamental investment objective and the principal investment strategy applicable to the Fund. The Mid Cap Growth Fund's Board of Directors may change its investment objective, without shareholder approval, upon 30 days written notice to all shareholders. What follows is additional information regarding securities in which the Fund may invest and investment practices in which it may engage. To determine whether the Fund purchases such securities or engages in such practices, see the chart on pages __ and __ of this Statement of Additional Information.

Securities Rating Agencies

Rating agencies are private services that provide ratings of the credit quality of fixed income securities. The following is a description of the fixed income securities ratings used by Moody's Investor Services, Inc. ("Moody's") and Standard & Poor's, a division of the McGraw-Hill Companies ("S&P"). Subsequent to its purchase by the Fund, a security may cease to be rated, or its rating may be reduced below the criteria set forth for the Fund. Neither event would require the elimination of the security from the Fund's portfolio, but the Advisor will consider that event in its determination of whether the Fund should continue to hold such security in its portfolio. Ratings assigned by a particular rating agency are not absolute standards of credit quality and do not evaluate market risk. Rating agencies may fail to make timely changes in credit ratings and an issuer's current financial condition may be better or worse than a rating indicates.

BOND RATINGS. MOODY'S -- The following is a description of Moody's bond ratings:

Aaa - Best quality; smallest degree of investment risk.

Aa - High quality by all standards.

Aa and Aaa are known as high-grade bonds.

A - Many favorable investment attributes; considered upper medium-grade obligations.

Baa - Medium-grade obligations; neither highly protected nor poorly secured. Interest and principal appear adequate for the present, but certain protective elements may be lacking or may be characteristically unreliable over any great length of time.

Ba - Speculative elements; future cannot be considered well assured. Protection of interest and principal payments may be very moderate and not well safeguarded during both good and bad times over the future.

B - Generally lack characteristics of a desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa - Poor standing, may be in default; elements of danger with respect to principal or interest.

S&P -- The following is a description of S&P's bond ratings:

AAA - Highest rating; extremely strong capacity to pay principal and interest.

AA - Also high-quality with a very strong capacity to pay principal and interest; differ from AAA issues only by a small degree.

3

A - Strong capacity to pay principal and interest; somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions.

BBB - Adequate capacity to pay principal and interest; normally exhibit adequate protection parameters, but adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay principal and interest than for higher-rated bonds.

Bonds rated AAA, AA, A, and BBB are considered investment grade bonds.

BB - Less near-term vulnerability to default than other speculative grade debt; face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to inadequate capacity to meet timely interest and principal payments.

B - Greater vulnerability to default but presently have the capacity to meet interest payments and principal repayments; adverse business, financial, or economic conditions would likely impair capacity or willingness to pay interest and repay principal.

CCC - Current identifiable vulnerability to default and dependent upon favorable business, financial, and economic conditions to meet timely payments of interest and repayments of principal. In the event of adverse business, financial, or economic conditions, they are not likely to have the capacity to pay interest and repay principal.

Bonds rated BB, B, and CCC are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal. BB indicates the least degree of speculation and CCC a higher degree of speculation. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions.

The Fund may purchase unrated securities (which are not rated by a rating agency) if the Advisor determines that a security is of comparable quality to a rated security that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that the Advisor may not accurately evaluate the security's comparative credit rating. Analysis of the creditworthiness of issuers of lower rated securities may be more complex than for issuers of higher-quality fixed income securities. To the extent that the Fund invests in unrated securities, the Fund's success in achieving its investment objective is determined more heavily by the Advisor's creditworthiness analysis than if the Fund invested exclusively in rated securities.

Non-Investment Grade Securities ("Junk Bonds")

Investments in securities rated below investment grade (i.e., rated Ba or lower by Moody's or BB or lower by S&P), which are eligible for purchase by the Fund are described as "speculative" by both Moody's and S&P. Investments in lower rated corporate debt securities ("high yield securities" or "junk bonds") generally provide greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and principal and income risk. These high yield securities are regarded as predominately speculative with respect to the issuer's continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality debt securities.

High yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment grade securities. The prices of high yield securities have been found to be less sensitive to interest-rate changes than higher-rated investments, but more sensitive to adverse economic downturns or individual corporate developments. A projection of an economic downturn or of a period of rising interest rates, for example, could cause a decline in high yield security prices because the advent of a recession could lessen the ability of a highly leveraged company to make principal and interest payments on its debt securities. If an issuer of debt securities defaults, in addition to risking payment of all or a portion of interest and principal, the Fund investing in such securities may incur additional expenses to seek recovery.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield security, and could adversely affect the daily net asset value of the Fund's shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of high yield securities, especially in a thinly-traded market. Since secondary markets for high yield securities are generally less liquid than the market for higher grade securities, it may be more difficult to value these securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation because there is less reliable, objective data available.

4

The use of credit ratings as the sole method of evaluating high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated. The Advisor does not rely solely on credit ratings when selecting securities for the Fund, and develops its own independent analysis of issuer credit quality.

Bank Obligations

Bank obligations in which the Fund may invest include certificates of deposit, bankers' acceptances, and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are "accepted" by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties, which vary depending upon market conditions and on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Bank obligations include foreign bank obligations including Eurodollar and Yankee obligations. Eurodollar bank obligations are dollar certificates of deposits and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks. Foreign bank obligations are subject to the same risks that pertain to domestic issues, notably credit risk and interest rate risk. Additionally, foreign bank obligations are subject to many of the same risks as investments in foreign securities (see "Foreign Equity Securities" below). Obligations of foreign banks involve somewhat different investment risks than those affecting obligations of United States banks, including the possibilities that their liquidity could be impaired because of future political and economic developments of the foreign bank's country, that their obligations may be less marketable than comparable obligations of United States banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted, which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Commercial Paper

A1 and Prime 1 are the highest commercial paper ratings issued by S&P and Moody's, respectively.

Commercial paper rated A1 by S&P has the following characteristics:
(1) liquidity ratios are adequate to meet cash requirements; (2) long-term senior debt is rated A or better; (3) the issuer has access to at least two additional channels of borrowing; (4) basic earnings and cash flow have an upward trend with an allowance made for unusual circumstances; (5) typically, the issuer's industry is well established and the issuer has a strong position within the industry; and (6) the reliability and quality of management are unquestioned.

Among the factors considered by Moody's in assigning ratings are the following: (1) evaluation of the management of the issuer; (2) economic evaluation of the issuer's industry or industries and an appraisal of speculative-type risks which may be inherent in certain areas; (3) evaluation of the issuer's products in relation to competition and customer acceptance; (4) liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over a period of 10 years; (7) financial strength of a parent company and the relationships which exist with the issuer; and (8) recognition by the management of obligations that may be present or may arise as a result of public interest questions and preparation to meet such obligations.

Government Securities

Government securities may be either direct obligations of the U.S. Treasury or may be the obligations of an agency or instrumentality of the United States.

TREASURY OBLIGATIONS. The U.S. Treasury issues a variety of marketable securities that are direct obligations of the U.S. Government. These securities fall into three categories - bills, notes, and bonds - distinguished primarily by their maturity at time of issuance. Treasury bills have maturities of one year or less at the time of issuance, while Treasury notes currently have maturities of 1 to 10 years. Treasury bonds can be issued with any maturity of more than 10 years.

5

OBLIGATIONS OF AGENCIES AND INSTRUMENTALITIES. Agencies and instrumentalities of the U.S. Government are created to fill specific governmental roles. Their activities are primarily financed through securities whose issuance has been authorized by Congress. Agencies and instrumentalities include the Export Import Bank, Federal Housing Administration, Government National Mortgage Association, Tennessee Valley Authority, Banks for Cooperatives, Farmers Home Administration, Federal Home Loan Banks, Federal Intermediate Credit Banks, Federal Land Banks, Federal National Mortgage Association, Federal Home Loan Mortgage Corp., U.S. Postal System, and Federal Finance Bank. Although obligations of "agencies" and "instrumentalities" are not direct obligations of the U.S. Treasury, payment of the interest or principal on these obligations is generally backed directly or indirectly by the U.S. Government. This support can range from backing by the full faith and credit of the United States or U.S. Treasury guarantees to the backing solely of the issuing instrumentality itself.

Mortgage-Backed Securities and Mortgage Pass-Through Securities

Mortgage-backed securities are interests in pools of mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. Mortgage-backed securities are sold to investors by various governmental, government-related and private organizations as further described below. The Fund may also invest in debt securities that are secured with collateral consisting of mortgage-backed securities (see "Collateralized Mortgage Obligations") and in other types of mortgage-related securities.

Because principal may be prepaid at any time, mortgage-backed securities involve significantly greater price and yield volatility than traditional debt securities. A decline in interest rates may lead to a faster rate of repayment of the underlying mortgages and expose the Fund to a lower rate of return upon reinvestment. To the extent that mortgage-backed securities are held by the Fund, the prepayment right will tend to limit to some degree the increase in net asset value of the Fund because the value of the mortgage-backed securities held by the Fund may not appreciate as rapidly as the price of non-callable debt securities. When interest rates rise, mortgage prepayment rates tend to decline, thus lengthening the duration of mortgage-related securities and increasing their price volatility, affecting the price volatility of the Fund's shares.

Interests in pools of mortgage-backed securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment that consists of both interest and principal payments. In effect, these payments are a "pass-through" of the monthly payments made by the individual borrowers on their mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs incurred. Some mortgage-related securities (such as securities issued by the Government National Mortgage Association) are described as "modified pass-through." These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

The principal governmental guarantor of mortgage-related securities is the Government National Mortgage Association ("GNMA"). GNMA is a wholly-owned U.S. Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks, and mortgage bankers) and backed by pools of FHA-insured or VA-guaranteed mortgages. These guarantees, however, do not apply to the market value or yield of mortgage-backed securities or to the value of the Fund's shares. Also, GNMA securities often are purchased at a premium over the maturity value of the underlying mortgages. This premium is not guaranteed and will be lost if prepayment occurs.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include the Federal National Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC"). FNMA is a government-sponsored corporation owned entirely by private stockholders. It is subject to regulation by the Secretary of Housing and Urban Development. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) mortgages from a list of approved seller/servicers, which include state and federally-chartered savings and loan associations, mutual savings banks, commercial banks, credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government.

FHLMC is a corporate instrumentality of the U.S. Government and was created in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. Its stock is owned by the twelve Federal Home Loan Banks. FHLMC issues Participation Certificates ("PCs"), which represent interests in conventional mortgages from FHLMC's national portfolio. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government.

6

Commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers, and other secondary market issuers also create pass-through pools of conventional mortgage loans. These issuers may, in addition, be the originators and/or servicers of the underlying mortgage loans as well as the guarantors of the mortgage-related securities. Pools created by non-governmental issuers generally offer a higher rate of interest than government and government-related pools because there are no direct or indirect government or agency guarantees of payment. However, timely payment of interest and principal of these pools may be supported by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance and letters of credit. The insurance and guarantees are issued by governmental entities, private insurers, and the mortgage poolers. Such insurance and guarantees and the creditworthiness of its issuers will be considered in determining whether a mortgage-related security meets the Fund's investment quality standards. There is no assurance that the private insurers or guarantors will meet their obligations under the insurance policies or guarantee arrangements. The Fund may buy mortgage-related securities without insurance or guarantees if, through an examination of the loan experience and practices of the originators/servicers and poolers, the Advisor determines that the securities meet the Fund's quality standards. Although the market for such securities is becoming increasingly liquid, securities issued by certain private organizations may not be readily marketable.

Collateralized Mortgage Obligations ("CMOs")

CMOs are hybrids between mortgage-backed bonds and mortgage pass-through securities. Similar to a bond, interest and prepaid principal are paid, in most cases, semiannually. CMOs may be collateralized by whole mortgage loans but are more typically collateralized by portfolios of mortgage pass-through securities, guaranteed by GNMA, FHLMC, or FNMA, and their income streams.

CMOs are structured into multiple classes, each bearing a different stated maturity. Actual maturity and average life will depend upon the prepayment experience of the collateral. CMOs provide for a modified form of call protection through a de facto breakdown of the underlying pool of mortgages according to how quickly the loans are repaid. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes receive principal only after the first class has been retired. An investor is partially protected against a sooner than desired return of principal by the sequential payments. The prices of certain CMOs, depending on their structure and the rate of prepayments, can be volatile. Some CMOs may also not be as liquid as other securities.

In a typical CMO transaction, a corporation issues multiple series, (e.g., A, B, C, Z) of CMO bonds ("Bonds"). Proceeds of the Bond offering are used to purchase mortgages or mortgage pass-through certificates ("Collateral"). The Collateral is pledged to a trustee as security for the Bonds. Principal and interest payments from the Collateral are used to pay principal on the Bonds in the order A, B, C, Z. The Series A, B, and C Bonds all pay interest currently. Interest on the Series Z Bond is accrued and added to principal and a like amount is paid as principal on the Series A, B, or C Bond currently being paid off. When the Series A, B, and C Bonds are paid in full, interest and principal on the Series Z Bond begins to be paid currently. With some CMOs, the issuer serves as a conduit to allow loan originators (primarily builders or savings and loan associations) to borrow against their loan portfolios.

The Fund will invest only in those CMOs whose characteristics and terms are consistent with the average maturity and market risk profile of the other fixed income securities held by the Fund.

Other Mortgage-Backed Securities

The Advisor expects that governmental, government-related or private entities may create mortgage loan pools and other mortgage-related securities offering mortgage pass-through and mortgage-collateralized investment in addition to those described above. The mortgages underlying these securities may include alternative mortgage instruments; that is, mortgage instruments whose principal or interest payments may vary or whose terms to maturity may differ from customary long-term fixed rate mortgages. As new types of mortgage-related securities are developed and offered to investors, the Advisor will, consistent with the Fund's investment objective, policies and quality standards, consider making investments in such new types of mortgage-related securities.

Other Asset-Backed Securities

The securitization techniques used to develop mortgage-backed securities are being applied to a broad range of assets. Through the use of trusts and special purpose corporations, various types of assets, including automobile loans, computer leases and credit card and other types of receivables, are being securitized in pass-through structures similar to mortgage pass-through structures described above or in a structure similar to the CMO structure. Consistent with the Fund's investment objectives and policies, the Fund may invest in these and other types of asset-backed securities that may be developed in the future. In general, the collateral supporting these securities is of shorter maturity than mortgage loans and is less likely to experience substantial prepayments with interest rate fluctuations.

7

These other asset-backed securities present certain risks that are not presented by mortgage-backed securities. Primarily, these securities may not have the benefit of any security interest in the related assets. Credit card receivables are generally unsecured and the debtors are entitled to the protection of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. There is the possibility that recoveries on repossessed collateral may not, in some cases, be available to support payments on these securities.

Asset-backed securities are often backed by a pool of assets representing the obligations of a number of direct parties. To reduce the effect of failures by obligors on underlying assets to make payments, the securities may contain elements of credit support which fall into two categories: (i) liquidity protection and (ii) protection against losses resulting from ultimate default by an obligor or the underlying assets. Liquidity protection refers to the making of advances, generally by the entity administering the pool of assets, to ensure that the receipt of payments on the underlying pool occurs in a timely fashion. Protection against losses results from payment of the insurance obligations on at least a portion of the assets in the pool. This protection may be provided through guarantee policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches. The Fund will not pay any additional or separate fees for credit support. The degree of credit support provided for each issue is generally based on historical information respecting the level of credit risk associated with the underlying assets. Delinquency or loss in excess of that anticipated, or failure of the credit support could adversely affect the return on an investment in such a security.

Floating or Variable Rate Securities

Floating or variable rate securities have interest rates that periodically change according to the rise and fall of a specified interest rate index or a specific fixed-income security that is used as a benchmark. The interest rate typically changes every six months, but for some securities the rate may fluctuate weekly, monthly, or quarterly. The index used is often the rate for 90- or 180-day Treasury Bills. Variable-rate and floating-rate securities may have interest rate ceilings or caps that fix the interest rate on such a security if, for example, a specified index exceeds a predetermined interest rate. If an interest rate on a security held by the Fund becomes fixed as a result of a ceiling or cap provision, the interest income received by the Fund will be limited by the rate of the ceiling or cap. In addition, the principal values of these types of securities will be adversely affected if market interest rates continue to exceed the ceiling or cap rate.

Options and Financial Futures Transactions

Certain Funds may invest up to 5 percent of their net assets in premiums on put and call exchange-traded options. A call option gives the holder
(buyer) the right to purchase a security at a specified price (the exercise price) at any time until a certain date (the expiration date). A put option gives the buyer the right to sell a security at the exercise price at any time until the expiration date. The Fund may also purchase options on securities indices. Options on securities indices are similar to options on a security except that, rather than the right to take or make delivery of a security at a specified price, an option on a securities index gives the holder the right to receive, on exercise of the option, an amount of cash if the closing level of the securities index on which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. The Fund may enter into closing transactions, exercise its options, or permit the options to expire.

The Fund may also write call options, but only if such options are covered. A call option is covered if written on a security the Fund owns or if the Fund has an absolute and immediate right to acquire that security without additional cash consideration upon conversion or exchange of other securities held by the Fund. If additional cash consideration is required, that amount must be held in a segregated account by the Fund's custodian bank. A call option on a securities index is covered if the Fund owns securities whose price changes, in the opinion of the Advisor, are expected to be substantially similar to those of the index. A call option may also be covered in any other manner in accordance with the rules of the exchange upon which the option is traded and applicable laws and regulations. The Fund may write such options on up to 25 percent of its net assets.

Financial futures contracts, including interest rate futures transactions, are commodity contracts that obligate the long or short holder to take or make delivery of a specified quantity of a financial instrument, such as a security or the cash value of a securities index, during a specified future period at a specified price. The Fund, however, intends to enter into financial futures transactions for which the aggregate initial margin exceeds 5 percent of the net assets of the Fund after taking into account unrealized profits and unrealized losses on any such transactions it has entered into. The Fund may engage in futures transactions only on commodities exchanges or boards of trade.

The Fund will not engage in transactions in index options, financial futures contracts, or related options for speculation. The Fund may engage in these transactions only as an attempt to hedge against market conditions affecting the values of securities that the Fund owns or intends to purchase. When the Fund purchases a put on a stock index or on a stock index future not held by the Fund, the put protects the Fund against a decline in the value of all securities held by it to the extent that the stock index moves in a similar pattern to the prices of the securities held. The correlation, however, between indices and price movements of the securities in which the Fund will

8

generally invest may be imperfect. It is expected, nonetheless, that the use of put options that relate to such indices will, in certain circumstances, protect against declines in values of specific portfolio securities or the Fund's portfolio generally. Although the purchase of a put option may partially protect the Fund from a decline in the value of a particular security or its portfolio generally, the cost of a put will reduce the potential return on the security or the portfolio if either increases in value.

Upon entering into a futures contract, the Fund will be required to deposit with its custodian in a segregated account cash, certain U.S. Government securities, or any other portfolio assets as permitted by the SEC's rules and regulations in an amount known as the "initial margin." This amount, which is subject to change, is in the nature of a performance bond or a good faith deposit on the contract and would be returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied.

The principal risks of options and futures transactions are: (a) possible imperfect correlation between movements in the prices of options, currencies, or futures contracts and movements in the prices of the securities or currencies hedged or used for cover; (b) lack of assurance that a liquid secondary market will exist for any particular options or futures contract when needed; (c) the need for additional skills and techniques beyond those required for normal portfolio management; (d) losses on futures contracts resulting from market movements not anticipated by the Advisor; and (e) possible need to defer closing out certain options or futures contracts to continue to qualify for beneficial tax treatment afforded "regulated investment companies" under the Internal Revenue Code of 1986, as amended (the "Code").

Swap Agreements ("Swaps," "Caps," "Collars" and "Floors")

The Fund may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift the Fund's investment exposure from one type of investment to another. For example, if the Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of the Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Fund's performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Fund may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

Foreign Equity Securities

Foreign equity securities include common stock and preferred stock, including securities convertible into equity securities, issued by foreign companies, American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs"). In determining whether a company is foreign, the Advisor will consider various factors including where the company is headquartered, where the company's principal operations are located, where the company's revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending upon the circumstances.

Foreign equity securities, which are generally denominated in foreign currencies, involve risks not typically associated with investing in domestic securities. Foreign securities may be subject to foreign taxes that would reduce their effective yield. Certain foreign governments levy withholding taxes against dividend and interest income. Although in some countries a portion of these taxes is recoverable, the unrecovered portion of any foreign withholding taxes would reduce the income the Fund receives from its foreign investments.

9

Foreign investments involve other risks, including possible political or economic instability of the country of the issuer, the difficulty of predicting international trade patterns, and the possibility of currency exchange controls. Foreign securities may also be subject to greater fluctuations in price than domestic securities. There may be less publicly available information about a foreign company than about a domestic company. Foreign companies generally are not subject to uniform accounting, auditing, and financial reporting standards comparable to those of domestic companies.

There is generally less government regulation of stock exchanges, brokers, and listed companies abroad than in the United States. In addition, with respect to certain foreign countries, there is a possibility of the adoption of a policy to withhold dividends at the source, or of expropriation, nationalization, confiscatory taxation, or diplomatic developments that could affect investments in those countries. Finally, in the event of default on a foreign debt obligation, it may be more difficult for the Fund to obtain or enforce a judgement against the issuers of the obligation. The Fund will normally execute their portfolio securities transactions on the principal stock exchange on which the security is traded.

The considerations noted above regarding the risk of investing in foreign securities are generally more significant for investments in emerging or developing countries, such as countries in Eastern Europe, Latin America, South America or Southeast Asia. These countries may have relatively unstable governments and securities markets in which only a small number of securities trade. Markets of developing or emerging countries may generally be more volatile than markets of developed countries. Investment in these markets may involve significantly greater risks, as well as the potential for greater gains.

ADRs in registered form are dollar-denominated securities designed for use in the U.S. securities markets. ADRs are sponsored and issued by domestic banks and represent and may be converted into underlying foreign securities deposited with the domestic bank or a correspondent bank. ADRs do not eliminate the risks inherent in investing in the securities of foreign issuers. By investing in ADRs rather than directly in the foreign security, however, the Fund may avoid currency risks during the settlement period for either purchases or sales. There is a large, liquid market in the United States for most ADRs. GDRs are receipts representing an arrangement with a major foreign bank similar to that for ADRs. GDRs are not necessarily denominated in the currency of the underlying security. While ADRs and GDRs will generally be considered foreign securities for purposes of calculation of any investment limitation placed on the Fund's exposure to foreign securities, these securities, along with the securities of foreign companies traded on NASDAQ will not be subject to any of the restrictions placed on the Fund's ability to invest in emerging market securities.

Additional costs may be incurred in connection with the Fund's foreign investments. Foreign brokerage commissions are generally higher than those in the United States. Expenses may also be incurred on currency conversions when the Fund moves investments from one country to another. Increased custodian costs as well as administrative difficulties may be experienced in connection with maintaining assets in foreign jurisdictions.

Foreign Fixed Income Securities

Foreign fixed income securities include debt securities of foreign corporate issuers, certain foreign bank obligations (see "Bank Obligations"), obligations of foreign governments or their subdivisions, agencies and instrumentalities, and obligations of supranational entities such as the World Bank, the European Investment Bank, and the Asian Development Bank. Any of these securities may be denominated in foreign currency or U.S. dollars, or may be traded in U.S. dollars in the United States although the underlying security is usually denominated in a foreign currency.

The risk of investing in foreign fixed income securities are the same as the risks of investing in foreign equity securities. Additionally, investment in sovereign debt (debt issued by governments and their agencies and instrumentality) can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be available or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity's willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity's policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities may also depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a governmental entity's implementation of economic reforms and/or economic performance and the timely service of such debtor's obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties' commitments to lend funds to the governmental entity, which may further impair such debtor's ability or willingness to service its debts in a timely manner. Consequently, governmental entities may default on their sovereign debt. Holders of sovereign debt (including the Fund) may be requested to participate in the

10

rescheduling of such debt and to the extend further loans to governmental entities. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

Currency Contracts

The value of the Fund invested in foreign securities will fluctuate as a result of changes in the exchange rates between the U.S. dollar and the currencies in which the foreign securities or bank deposits held by the Fund are denominated. To reduce or limit exposure to changes in currency exchange rates (referred to as "hedging"), the Fund may enter into forward currency exchange contracts that, in effect, lock in a rate of exchange during the period of the forward contracts. Forward contracts are usually entered into with currency traders, are not traded on securities exchanges, and usually have a term of less than one year, but can be renewed. A default on a contract would deprive the Fund of unrealized profits or force the Fund to cover its commitments for purchase or sale of currency, if any, at the market price. The Fund will enter into forward contracts only for hedging purposes and not for speculation. If required by the Investment Company Act of 1940, as amended (the "1940 Act") or the SEC, the Fund may "cover" its commitment under forward contracts by segregating cash or liquid securities with the Fund's custodian in an amount not less than the current value of the Fund's total assets committed to the consummation of the contracts.

The Fund may also purchase or sell foreign currencies on a "spot"
(cash) basis or on a forward basis to lock in the U.S. dollar value of a transaction at the exchange rate or rates then prevailing. The Fund will use this hedging technique in an attempt to insulate itself against possible losses resulting from a change in the relationship between the U.S. dollar and the relevant foreign currency during the period between the date a security is purchased or sold and the date on which payment is made or received.

Hedging against adverse changes in exchange rates will not eliminate fluctuation in the prices of the Fund's portfolio securities or prevent loss if the prices of those securities decline. In addition, the use of forward contracts may limit potential gains from an appreciation in the U.S. dollar value of a foreign currency. Forecasting short-term currency market movements is very difficult, and there is no assurance that short-term hedging strategies used by the Fund will be successful.

Real Estate Investment Trusts ("REITs")

REITs are pooled investment vehicles that invest primarily in real estate--such as shopping centers, malls, multi-family housing, or commercial property, or real-estate related loans such as mortgages. Investing in REITs involves unique risks and may be affected by changes in the value of the underlying property owned by the REIT or affected by the quality of the credit extended. REITs are significantly affected by the market for real estate and are subject to many of the same risks associated with direct ownership in real estate. Furthermore, REITs are dependent upon management skills and subject to heavy cash flow dependency.

Repurchase Agreements

The Fund may invest in repurchase agreements, which are agreements by which the Fund purchases a security and simultaneously commits to resell that security to the seller (a commercial bank or securities dealer) at a stated price within a number of days (usually not more than seven) from the date of purchase. The resale price reflects the purchase price plus a rate of interest that is unrelated to the coupon rate or maturity of the purchased security. Repurchase agreements may be considered loans by the Fund collateralized by the underlying security. The obligation of the seller to pay the stated price is in effect secured by the underlying security. The seller will be required to maintain the value of the collateral underlying any repurchase agreement at a level at least equal to the price of the repurchase agreement. In the case of default by the seller, the Fund could incur a loss. In the event of a bankruptcy proceeding commenced against the seller, the Fund may incur costs and delays in realizing upon the collateral. The Fund will enter into repurchase agreements only with those banks or securities dealers who are deemed creditworthy pursuant to criteria adopted by the Advisor. There is no limit on the portion of the Fund's assets that may be invested in repurchase agreements with maturities of seven days or less.

Borrowing

The Fund may borrow from a bank for temporary administrative purposes. This borrowing may be unsecured. Provisions of the 1940 Act require the Fund to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300 percent of the amount borrowed, with an exception for borrowings not in excess of 5 percent of the Fund's total assets made for temporary administrative purposes. Any borrowings for temporary administrative purposes in excess of 5 percent of the Fund's total assets are subject to continuous asset coverage. If the 300 percent asset coverage declines as a result of market fluctuations or other reasons, the Fund may be required to sell some of its portfolio holdings within three days to reduce the debt and restore the 300 percent asset coverage. The Fund also may enter into certain transactions, including reverse repurchase agreements, mortgage dollar rolls, and sale-

11

buybacks, that can be viewed as constituting a form of borrowing or financing transaction by the Fund. To the extent the Fund covers its commitment under such transactions (or economically similar transaction) by the segregation of assets determined in accordance with procedures adopted by the Board of Directors, equal in value to the amount of the Fund's commitment to repurchase, such an agreement will not be considered a "senior security" by the Fund and therefore will not be subject to the 300 percent asset coverage requirement otherwise applicable to borrowings by the Fund. Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund's portfolio. Money borrowed will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased. The Fund also may be required to maintain minimum average balances in connection with such borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

Illiquid Securities

Illiquid securities are securities that may not be sold or disposed of in the ordinary course of business within seven days at approximately the price used to determine the Fund's net asset value. Under current interpretations of the Staff of the SEC, the following instruments in which the Fund may invest will be considered illiquid: (1) repurchase agreements maturing in more than seven days; (2) restricted securities (securities whose public resale is subject to legal restrictions, except as described in the following paragraph); (3) options, with respect to specific securities, not traded on a national securities exchange that are not readily marketable; and (4) any other securities in which the Fund may invest that are not readily marketable.

Notwithstanding the restrictions applicable to investments in illiquid securities described in the relevant chart below, the Fund may purchase without limit certain restricted securities that can be resold to qualifying institutions pursuant to a regulatory exemption under Rule 144A ("Rule 144A securities"). If a dealer or institutional trading market exists for Rule 144A securities, such securities are deemed to be liquid and thus exempt from that Fund's liquidity restrictions.

Under the supervision of the Board of Directors of the Fund, the Advisor determines the liquidity of the Fund's portfolio securities, including Rule 144A securities, and, through reports from the Advisor, the Board of Directors monitors trading activity in these securities. In reaching liquidity decisions, the Advisor will consider, among other things, the following factors:
(1) the frequency of trades and quotes for the security; (2) the number of dealers willing to purchase or sell the security and the number of other potential purchasers; (3) dealer undertakings to make a market in the security; and (4) the nature of the security and the marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the procedures for the transfer). If institutional trading in Rule 144A securities declines, the Fund's liquidity could be adversely affected to the extent it is invested in such securities.

Convertible Securities and Warrants

Convertible debentures are interest-bearing debt securities, typically unsecured, that represent an obligation of the corporation providing the owner with claims to the corporation's earnings and assets before common and preferred stock owners, generally on par with unsecured creditors. If unsecured, claims of convertible debenture owners would be inferior to claims of secured debt holders. Convertible preferred stocks are securities that represent an ownership interest in a corporation providing the owner with claims to the corporation's earnings and assets before common stock owners, but after bond owners. Investments by the Fund in convertible debentures or convertible preferred stock would be a substitute for an investment in the convertible security if available in quantities necessary to satisfy the Fund's investment needs (for example, in the case of a new issuance of convertible securities) or where, because of financial market conditions, the conversion price of the convertible security is comparable to the price of the underlying common stock, in which case a preferred position with respect to the corporation's earnings and assets may be preferable to holding common stock.

Warrants are options to buy a stated number of underlying securities at a specified price any time during the life of the warrants. The securities underlying these warrants will be the same types of securities that the Fund will invest in to achieve its investment objective of capital appreciation. The purchaser of a warrant expects the market price of the underlying security will exceed the purchase price of the warrant plus the exercise price of the warrant, thus resulting in a profit. If the market price never exceeds the purchase price plus the exercise price of the warrant before the expiration date of the warrant, the purchaser will suffer a loss equal to the purchase price of the warrant.

Investments in Small and Unseasoned Companies

Unseasoned and small companies may have limited or unprofitable operating histories, limited financial resources, and inexperienced management. In addition, they often face competition from larger or more established firms that have greater resources. Securities of small and unseasoned companies are frequently traded in the over-the-counter market or on regional exchanges where low trading volumes may result in erratic or abrupt price movements. To dispose of these securities, the Fund may need to sell them over an

12

extended period or below the original purchase price. Investments by the Fund in these small or unseasoned companies may be regarded as speculative.

Dollar Roll Transactions

"Dollar roll" transactions consist of the sale by the Fund to a bank or broker-dealer (the "counterparty") of GNMA certificates or other mortgage-backed securities together with a commitment to purchase from the counterparty similar, but not identical, securities at a future date and at agreed price. The counterparty receives all principal and interest payments, including prepayments, made on the security while it is the holder. The Fund receives a fee from the counterparty as consideration for entering into the commitment to purchase. Dollar rolls may be renewed over a period of several months with a new purchase and repurchase price fixed and a cash settlement made at each renewal without physical delivery of securities. Moreover, the transaction may be preceded by a firm commitment agreement pursuant to which the Fund agrees to buy a security on a future date.

The Fund will not use such transactions for leveraging purposes and, accordingly, will segregate liquid assets in an amount sufficient to meet their purchase obligations under the transactions. The Fund will also maintain asset coverage of at least 300 percent for all outstanding firm commitments, dollar rolls and other borrowings.

Dollar rolls may be treated for purposes of the 1940 Act as borrowings of the Fund because they involve the sale of a security coupled with an agreement to repurchase. Like all borrowings, a dollar roll involves costs to the Fund. For example, while the Fund receives a fee as consideration for agreeing to repurchase the security, the Fund forgoes the right to receive all principal and interest payments while the counterparty holds the security. These payments received by the counterparty may exceed the fee received by the Fund, thereby effectively charging the Fund interest on its borrowing. Further, although the Fund can estimate the amount of expected principal prepayment over the term of the dollar roll, a variation in the actual amount of prepayment could increase or decease the cost of the Fund's borrowing.

When-Issued Securities

When-issued, delayed-delivery and forward transactions generally involve the purchase of a security with payment and delivery in the future (i.e., beyond normal settlement). The Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. New issues of stocks and bonds, private placements and U.S. Government securities may be sold in this manner. To the extent the Fund engages in when-issued and delayed-delivery transactions, it will do so to acquire portfolio securities consistent with its investment objectives and policies and not for investment leverage. The Fund may use spot and forward currency exchange transactions to reduce the risk associated with fluctuations in exchange rates when securities are purchased or sold on a when-issued or delayed delivery basis.

Zero-Coupon and Pay-in-Kind Securities

A zero-coupon security has no cash coupon payments. Instead, the issuer sells the security at a substantial discount from its maturity value. The interest equivalent received by the investor from holding this security to maturity is the difference between the maturity value and the purchase price. Pay-in-kind securities are securities that pay interest in either cash or additional securities, at the issuer's option, for a specified period. The price of pay-in-kind securities is expected to reflect the market value of the underlying accrued interest, since the last payment. Zero-coupon and pay-in-kind securities are more volatile than cash pay securities. The Fund accrues income on these securities prior to the receipt of cash payments. The Fund intends to distribute substantially all of its income to its shareholders to qualify for pass-through treatment under the tax laws and may, therefore, need to use its cash reserves to satisfy distribution requirements.

Temporary Investments

When, as a result of market conditions, the Advisor determines a temporary defensive position is warranted to help preserve capital, the Fund may without limit temporarily retain cash, or invest in prime commercial paper, high-grade debt securities, securities of the U.S. Government and its agencies and instrumentalities, and high-quality money market instruments, including repurchase agreements. When the Fund assumes a temporary defensive position, it is not invested in securities designed to achieve its investment objective.

INVESTMENT RESTRICTIONS

The Prospectus sets forth the investment goals and principal investment strategies applicable to the Fund. The following is a list of investment restrictions applicable to the Fund. If a percentage limitation is adhered to at the time of an investment by the Fund, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of the restriction. Except as stated otherwise below, the Fund may not change these restrictions without the approval of a majority of its shareholders, which means the vote at any meeting of shareholders of the Fund of
(i) 67 percent or more of the shares present or represented by proxy at the meeting (if the holders of more than 50 percent of the outstanding shares are present or represented by proxy) or (ii) more than 50 percent of the outstanding shares, whichever is less.

COLUMBIA MID CAP GROWTH FUND, INC.

The Mid Cap Growth Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or
(b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) the Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

The following is a list of non-fundamental investment restrictions applicable to the Fund. These restrictions can be changed by the Board, but the change will only be effective after notice is given (60 days notice in the case of non-fundamental restriction #2) to shareholders of the Fund.

The Fund may not:

1. Purchase or otherwise acquire any security if, as a result, more than 15% of its net assets would be invested in securities that are illiquid.

15

2. Invest less than 80% of its assets in the stocks of mid-cap companies (those stocks with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Mid Cap Index), except when the Fund is taking a temporary defensive position due to a determination by the Fund's Advisor that adverse market conditions make it desirable to suspend temporarily the Fund's normal investment activities.

Approval of Investment Advisory Contract

The Fund has entered into an investment advisory contract with the Advisor. The investment advisory contract is subject to annual approval of the Board of Directors, including a majority of disinterested directors. The existing contract for the Fund was considered and approved at in-person meetings of the Fund's Boards of Directors held on October 12, 2005. In determining the reasonableness of the advisory fees under each of the contracts, the directors considered several factors, including:

- The nature and quality of services provided to the Fund's shareholders,

- The profitability of the advisory contract for the Advisor,

- Fall-out benefits realized by the Advisor from services as advisor to the Fund,

- A comparison of fee structures with other mutual funds, and

- The existence of economies of scale with respect to the provision of investment advice to the Fund.

In reviewing the quality of services provided by the Advisor, the directors reviewed the performance and expense rankings of the Fund as compared to its peers, based upon information compiled by Lipper, Inc. The directors reviewed the following information: (1) total expense rankings within the Fund's expense group, (2) actual management fee rankings of the Fund within its expense group,
(3) contractual management fee rankings of the Fund within its expense group and
(4) performance rankings within the Fund's peer universe for the one-, three-, five- and ten-year periods. In addition, the directors reviewed data for the Fund comparing various return rankings of the Fund versus the Fund's actual management or total expense ranking. From this information, an overall Fund assessment ranking is made for the Fund. The Funds received a satisfactory ranking by the directors.

The directors also reviewed data related to the profitability of the Advisor with respect to its contract with the Fund. The directors considered the additional benefits to the Advisor as a result of its relationship with the Fund. The directors also considered the benefits to affiliates of the Advisor as the result of its management of the Fund.

24

After considering these and other factors, and the Fund's specific circumstances, the directors concluded that the Fund's advisory contract with the Advisor was reasonable for the Fund and in the best interests of its shareholders. During their deliberations, the directors requested from the Advisor all information reasonably necessary for the directors to evaluate the advisory contract for the Fund. The disinterested directors were also assisted by, and met separately with, their independent counsel.

See the section entitled "INVESTMENT ADVISORY AND OTHER FEES PAID TO AFFILIATES" for further information about the Advisor and each Fund's investment advisory contract.

Director Compensation:

The directors serve as directors/trustees of all open-end funds managed by the Advisor for which each director will receive an annual retainer of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expense Committee receives a supplemental retainer at an annual rate of $15,000; and the chair of each other committee receives a supplemental retainer at the annual rate of $10,000. Members of each committee receive $2,500 for each committee meeting held in person and $1,000 for each telephonic meeting. The chair of the Audit Committee receives an additional $500 per meeting supplement. Two-thirds of the director fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The following table sets forth compensation earned by the Funds' directors for the fiscal year ended August 31, 2005. No officer of the Funds received any compensation from the Funds in 2005.

Compensation

As of the Fund's most recent fiscal year end, the portfolio manager received all of his compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

Potential conflicts of interest in managing multiple accounts

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

26

- The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

27

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

Share Ownership:

As of December 30, 2006, each director and all officers and directors, as a group, owned of record or beneficially less than 1% of the outstanding shares of the Fund.

As of December 30, 2006, to the knowledge of the Fund, no person owned of record or beneficially more than 5% of the outstanding shares of the Fund except the following record owners:

PROXY VOTING POLICY AND PROCEDURES

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund.

The Advisor's policy is to vote all proxies for each client's securities in a manner considered by the Advisor to be in the best interest of its clients, including the Fund and its shareholders, without regard to any benefit to the Advisor or its affiliates. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to effect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, or its other clients or certain other persons. A member of the Proxy Committee is prohibited from voting on any proposal with respect to which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has three classes of proxy proposals. The first two classes are predetermined guidelines to vote for or against specific proposals, unless otherwise directed by the Proxy Committee. The third class is proposals requiring special consideration by the Proxy Committee. In addition, the Proxy Committee considers requests to vote on proposals in the first two classes other than according to the predetermined guidelines.

The Advisor generally votes in favor of proposals related to the following matters: selection of auditors (unless the auditor receives more than 50% of its revenues from non-audit activities from the company and its affiliates), election of directors (unless the proposal gives management the ability to alter the size of the board without shareholder approval), different persons for chairman of the board /chief executive officer (unless, in light of the size of the company and the nature of its shareholder base, the role of chairman and

29

CEO should not be held by different persons), compensation (if provisions are consistent with standard business practices), debt limits (unless proposed specifically as an anti-takeover action), indemnification (unless for negligence and or breaches of fiduciary duty), meetings, name of company, principal office (unless the purpose is to reduce regulatory or financial supervision), reports and accounts (if the certifications required by the Sarbanes-Oxley Act of 2002 have been provided), par value, shares (unless proposed as an anti-takeover action), share repurchase programs, independent committees, and equal opportunity employment.

The Advisor generally votes against proposals related to the following matters: super majority voting, cumulative voting, preferred stock, warrants, rights, poison pills, reclassification of common stock and meetings held by written consent.

The Advisor gives the following matters special consideration: new proposals, proxies of investment company shares (other than election of directors, selection of accountants), mergers/acquisitions (proposals where a hostile merger/acquisition is apparent or where the Advisor represents ownership in more than one of the companies involved), shareholder proposals (other than those covered by the predetermined guidelines), executive/director compensation (other than those covered by the predetermined guidelines), pre-emptive rights, and proxies of international issuers which block securities sales between submission of a proxy and the meeting (proposals for these securities are voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with predetermined guidelines).

In addition, if a portfolio manager or other party involved with an Advisor client or a Fund account concludes that the interest of the client or the Fund requires that a proxy be voted on a proposal other than according to the predetermined guidelines, he or she may request that the Proxy Committee consider voting the proxy differently. If any person (or entity) requests the Proxy Committee (or any of its members) to vote a proxy other than according to a predetermined guideline, that person must furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's (or entity's) relationship with the party proposing the matter to shareholders or any other matter known to the person that would create a potential conflict of interest.

The Proxy Committee may vary from the predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to effect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted.

The Advisor's Proxy Committee is composed of operational and investment representatives of its regional offices as well as senior representatives of equity investments, equity research, compliance and legal. During the first quarter of each year, the Proxy Committee reviews all guidelines and establishes guidelines for expected new proposals. In addition to these reviews and its other responsibilities described above, it's the Proxy Committee's functions include annual review of it's the Advisor's Proxy Voting Policy and Procedures to ensure consistency with internal policies and regulatory agency policies, and to develop and modify voting guidelines and procedures as it deems appropriate or necessary.

The Advisor uses Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The actual voting records of the Fund relating to its portfolio securities during the 12-month period ended June 30, 2005 are available without charge, upon request, by calling 1-800-426-3750, or by accessing the SEC's website at http://www.sec.gov.

INVESTMENT ADVISORY AND OTHER SERVICES PROVIDED BY AFFILIATES

Pursuant to the investment contract, the Advisor provides research, advice, and supervision with respect to investment matters and determines which securities to purchase or sell and what portion of the Fund's assets to invest.

The Advisor provides office space and pays all executive salaries and executive expenses of the Fund. The Fund assumes its costs relating to corporate matters, cost of services to shareholders, transfer and dividend paying agent fees, custodian fees, legal and auditing expenses, disinterested director fees, taxes and governmental fees, interest, brokers' commissions, transaction expenses, cost of stock certificates and any other expenses (including clerical expenses) of issue, sale, repurchase, or redemption of its shares, expenses of registering or qualifying its shares for sale, transfer taxes, and all other expenses of preparing its registration statement, prospectuses, and reports.

Fees paid by the Fund and expenses incurred by the Fund as reported below are Fund-level expenses paid by shares of the Fund outstanding as of the periods being reported.

Information regarding the advisory fee payable to the Advisor including any waivers or offsets applicable to such Fund is set forth in the prospectus for each Fund.

Effective November 1, 2004, pursuant to an amendment to the Investment Management Agreement with the Advisor, the advisory fee for the following Fund is calculated as a percentage of net assets that declines as net assets increase and is as follows:

Mid Cap Growth Fund   0.820% of the Fund's first $500 million of net assets;
                      0.750% of next $500 million of net assets;
                      0.720% of next $500 million of net assets; and
                      0.670% of net assets in excess of $1.5 billion.

Prior to November 1, 2004, the advisory fee for the Fund was calculated as a percentage of net assets that declined as net assets increased and was as follows:

Mid Cap Growth Fund 1.000% of the Fund's first $500 million of net assets; 0.750% of net assets in excess of $500 million.

Advisory fees paid by the Fund for each of the last three fiscal years were as follows:

FUND                     2005         2004         2003*
----                     ----         ----         -----
Mid Cap Growth Fund   $6,887,146   $8,813,801   $5,318,563


* The Fund changed its fiscal year end from December 31 to August 31 in 2003. Information provided is for the eight-month period ended August 31, 2003.

The Advisor provides certain administrative services to the Fund. Effective November 1, 2005, the Fund entered into an Administrative Agreement with the Advisor. For services provided under the Administrative Agreement, the Fund will pay the Advisor an annual fee, payable monthly, based on the Fund's net assets. The Advisor has delegated responsibility for certain administrative services to State Street. For periods before November 1, 2005, the Fund paid the Adviser fees under a similar Administrative Agreement at the same rates.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Fund. Its address is P.O. Box 8081, Boston Massachusetts 02266-8081. Effective November 1, 2005, the Fund entered into a Transfer, Dividend Disbursing and Shareholders' Servicing Agent Agreement with CMS, under which CMS will provide transfer agency, dividend disbursing and shareholders'

32

servicing agency services to the Fund. For these services, the Fund will pay CMS a specified amount per open account per annum, payable monthly. In addition the Fund may pay CMS the fees and expenses that CMS pays to third-party dealer firms that maintain omnibus accounts with the Fund, subject to a cap equal to a specified percentage of the Fund's net assets represented by the account. The Fund will also reimburse CMS for certain out-of-pocket expenses. CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Fund and interest (net of bank charges) and balance credits earned with respect to balances in demand deposit accounts CMS maintains in connection with its services to the Fund. CMS has retained Boston Financial Data Services, Inc. and DST Systems, Inc. to provide certain services for the Fund.

The transfer agent fees paid to CMS for the fiscal year ended August 31, 2005 under the transfer agent agreement were $831,320 for the Mid Cap Growth Fund,. The transfer agent fees paid by Mid Cap Growth Fund are net of transfer agent fees waived by CMS.

The Advisor provides certain pricing and bookkeeping services to the Fund. Effective November 1, 2005, the Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Fund will continue to receive substantially the same pricing, bookkeeping and administrative services as it currently receives under the Agreement. The Advisor and State Street Bank and Trust Company will continue to provide these services to the Fund. For services provided under the Pricing and Bookkeeping Agreement, the Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus 0.015% of the Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. The Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement.

Columbia Management Distributors, Inc. ("CMD"), a registered securities broker and a member of the National Association of Securities Dealers, Inc., whose address is One Financial Center Boston, MA 02111-2621, is the principal underwriter for the Fund, and is authorized under a distribution agreement with the Fund to sell shares of the Fund. CMD has no obligation to buy the Fund's shares, and purchases the Fund's shares only upon receipt of orders from authorized financial services firms ("FSFs") or investors. Shareholders of the Fund's Class R shares do not pay a sales charge upon purchase or sale of the Fund's shares.

The Advisor and CMS are wholly owned subsidiaries of Columbia Management Group, Inc., which is an indirect wholly owned subsidiary of Bank of America Financial Corporation ("Bank of America"). CMD is a wholly owned subsidiary of the Advisor. Bank of America and its affiliates provide a wide range of banking, financial, and investment products and services to individuals and businesses. Their principal activities include customer and commercial banking, mortgage lending and servicing, trust administration, investment management, retirement plan services, brokerage and clearing services, securities underwriting, private and corporate financing and advisory activities, and insurance services.

PORTFOLIO TRANSACTIONS

The Fund will not generally invest in securities for short-term capital appreciation but, when business and economic conditions, market prices, or the Fund's investment policy warrant, individual security positions may be sold without regard to the length of time they have been held. This may result in a higher portfolio turnover rate and increase the Fund's transaction costs, including brokerage commissions. To the extent short-term trades result in gains on securities held less than one year, shareholders will be subject to taxes at ordinary income rates. See "TAXES" in this Statement of Additional Information.

The Fund may purchase portfolio securities through a securities broker and pay the broker a commission, or it may purchase the securities directly from a dealer which acts as principal and sells securities directly for its own account without charging a commission. The purchase price of securities purchased from dealers serving as market makers will include the spread between the bid and asked prices. The Fund may also purchase securities from underwriters, the price of which will include a commission or discount paid by the issuer to the underwriter. There is generally no stated commission in the case of fixed income securities that are traded in the over-the-counter market, but the price paid by a Fund usually includes an undisclosed dealer commission or mark-up.

Prompt execution of orders at the most favorable price will be the primary consideration of the Fund in transactions where fees or commissions are involved. Additional factors considered by the Advisor in selecting brokers to execute a transaction include the: (i) professional capability of the executing broker and the value and quality of the brokerage services provided; (ii) size and type of transaction;

33

(iii) timing of transaction in the context of market prices and trends; (iv) nature and character of markets for the security to be purchased or sold; (v) the broker's execution efficiency and settlement capability; (vi) the broker's experience and financial stability and the execution services it renders to the Advisor on a continuing basis; and (vii) reasonableness of commission. The Fund recently adopted policies prohibiting the Fund from directing commissions to any broker-dealer for sale of the Fund's shares.

Research, statistical, and other services offered by the broker also may be taken into consideration in selecting broker-dealers. These services may include: advice concerning the value of securities, the advisability of investing in, purchasing, or selling securities, and the availability of securities or the purchasers or sellers of securities; and furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategies, and performance of accounts. A commission in excess of the amount of a commission another broker or dealer would have charged for effecting a transaction may be paid by a Fund if the Advisor determines in good faith that the commission is reasonable in relation to the value of the brokerage and research services provided, viewed in terms of either that particular transaction or management's overall responsibilities with respect to the Fund.

The Advisor receives a significant amount of proprietary research from a number of brokerage firms, in most cases on an unsolicited basis. The Advisor does not make any commitments to allocate brokerage for proprietary research. The value of that research, however, is considered along with other factors in the selection of brokers. This research is considered supplemental to the Advisor's own internal research and does not, therefore, materially reduce the overall expenses incurred by the Advisor for its research. On a semi-annual basis, the Advisor's research analysts and portfolio managers participate in a detailed internal survey regarding the value of proprietary research and the skills or contributions made by the various brokerage analysts to the Advisor's investment process. Firms are then confidentially ranked based on that survey. Brokerage allocations are then made, as much as reasonably possible, based on those rankings.

The Advisor may use the Fund's commissions to acquire third party research or products that are not available through its full-service brokers. In these arrangements, the Advisor pays an executing broker a commission equal to the average rate paid on all other trades and achieves what it believes is best execution on the trade. The executing broker then uses a portion of the commission to pay for a specific research service or product provided to the Advisor. Proposed research to be acquired in this manner must be approved by the Advisor's Soft Dollar Committee which is responsible for determining that the research provides appropriate assistance to the Advisor in connection with its investment management of the Fund and that the price paid with broker commissions is fair and reasonable.

The receipt of proprietary and third party research services or products from brokers or dealers might be useful to the Advisor and its affiliates in rendering investment management services to the Fund or other clients. Conversely, research provided by brokers or dealers who have executed orders on behalf of other clients of the Advisor and its affiliates might be useful to the Advisor in carrying out its obligations to the Fund.

Total brokerage commissions paid (agency only) by the Fund for each of the last three fiscal years were:

FUND                     2005         2004         2003*        2002
----                     ----         ----         -----        ----
Mid Cap Growth Fund   $2,899,948   $4,568,079   $2,792,191   $2,756,879

* The Fund changed its fiscal year end from December 31 to August 31 in 2003. Information provided is for the eight-month period ended August 31, 2003.

Of the commissions paid in 2005, the Mid Cap Growth Fund paid $_____ to acquire third-party research or products.

At August 31, 2005, the Fund held securities of its regular brokers or dealers as set forth below:

FUND                  BROKER/DEALER   VALUE
----                  -------------   -----
MID CAP GROWTH FUND   None

Provided the Fund's Board of Directors is satisfied that the Fund is receiving the most favorable price and execution available, the Advisor may consider the sale of the Fund's shares as a factor in the selection of brokerage firms to execute its portfolio transactions. The placement of portfolio transactions with brokerage firms who sell shares of a Fund is subject to rules adopted by the National Association of Securities Dealers, Inc. The Advisor may use research services provided by and allocate purchase and sale orders for portfolio securities to certain financial institutions, including, to the extent permitted by law or order of the SEC, financial institutions that are affiliated with the Advisor, if the Advisor believes that the quality of the transaction and the commission are comparable to what they would be with

34

other qualified brokerage firms. During 2004, the Fund periodically used W.R. Hambrecht, an affiliated broker-dealer of the Advisor to execute purchase and sale orders.

The aggregate dollar amount of brokerage commissions paid to W.R. Hambrecht for the fiscal year 2004 is as follows:

FUND                    2004
----                    ----
Mid Cap Growth Fund   $9,785

The Fund paid no brokerage commissions to W.R. Hambrecht or Bank of America Securities in fiscal year 2005.

For all years, the aggregate dollar amount of purchase and sale transactions and total broker commissions were less than 1% of the Fund's total purchase and sale transactions and broker commissions. In addition to agency transactions, the Fund may purchase securities from an underwriting syndicate in which an affiliate is a member of the underwriting syndicate. Such trades will be executed in accordance with the rules and regulations of the 1940 Act, as well as procedures adopted by the Fund.

Buy and sell orders of a Fund may be aggregated by the Advisor with other trades made at the regional trading desk at which the trade is completed with those of other Funds or accounts or other investment pools managed by the Advisor or affiliates of the Advisor to achieve best execution, and, on the average, lower brokerage commission costs. Orders are aggregated only if the Advisor, in the exercise of its investment discretion, believes such aggregation is consistent with its duty to seek best execution and if each client involved in the order is treated fairly and on an equitable basis. Each client that participates in an aggregated order will typically participate at the average share price for all transactions in that order, with all transaction costs shared on a pro rata basis. Absent unusual circumstances, an aggregated order that is only partially completed by the Advisor will be allocated to each client on a pro rata basis based on the percentage of the combined order actually filled. Notwithstanding the above, the Advisor may execute buy and sell orders for clients and take action in performance of its duties with respect to any of its clients that may differ from actions taken with respect to another client with similar investment policies and objectives, so long as the Advisor shall, to the extent practical, allocate investment opportunities to clients over a period of time on a fair and equitable basis and in accordance with applicable law.

Allocations among accounts managed by the Advisor of investments in initial and secondary public offerings ("IPOs and "SPOs," jointly "POs") are made pursuant to Guidelines (the "Guidelines") established by the Advisor. The Guidelines establish which accounts are eligible to participate in a particular PO and what level of participation is permitted. After eligible accounts are identified, each manager receives, on behalf of his or her accounts, a pro rata share of such allocation. The allocation by the manager among his or her accounts is further divided among such accounts on a pro rata basis. A manager may decline to participate in an offering, or may elect to not have all accounts participate, even if his or her accounts are eligible to participate pursuant to the guidelines if he or she believes that the PO is not appropriate for his or her accounts or an individual account. A manager who declines to participate must document the basis of his or her decision not to participate. Over time, allocations to eligible accounts for which an PO opportunity is appropriate will be made on a fair and equitable basis.

The Advisor, CMD and the Funds maintain a Code of Ethics pursuant to Rule 17j-1 under the 1940 Act (the "Ethics Code") that sets forth general and specific standards relating to the securities trading activities of all their employees. The Ethics Code does not prohibit employees from purchasing securities that may be purchased or held by the Funds, but is intended to ensure that all employees conduct their personal transactions in a manner that does not interfere with the portfolio transactions of the Funds or the Advisor's other clients or take unfair advantage of their relationship with the Advisor. The specific standards in the Ethics Code include, among others, a requirement that trades of all access persons be pre-cleared; a prohibition on investing in initial public offerings; required pre-approval of an investment in private placements; a prohibition on portfolio managers trading in a security five business days before or after a trade in the same security by an account over which the manager exercises investment discretion; and a prohibition on realizing any profit on the trading of a security held less than 60 days. Certain securities and transactions, such as U.S. Treasuries and purchases of options on securities indexes or securities under an automatic dividend reinvestment plan, are exempt from the restrictions in the Ethics Code because they present little or no potential for abuse. In addition to the trading restrictions, the Ethics Code contains reporting obligations that are designed to ensure compliance and allow the Advisor's Ethics Committee to monitor that compliance.

The Advisor and the Funds have also adopted an Insider Trading Policy. The Insider Trading Policy prohibits any employee from trading, either personally or on behalf of others (including a client account), on the basis of material nonpublic information. All employees are required to certify each year that they have read and complied with the provisions of the Ethics Code and the Insider Trading Policy.

CAPITAL STOCK AND OTHER SECURITIES

The Fund is an Oregon corporation and was organized in the year set forth below opposite its name.

FUND                  DATE
----                  ----
Mid Cap Growth Fund   1985

The Fund offers the following classes of shares pursuant to a Rule 18f-3 Plan (the "Plan") adopted by the Directors in accordance with the 1940 Act:
Class A, B, C, D, G, T, R and Z. A Statement of Additional Information pertaining to these other classes of shares of the Fund may be obtained from CMD upon request; the information presented within this Statement of Additional Information pertains to Class R shares of the Fund. Shares of each class of the Fund represent an equal pro rata interest in the Fund and, generally, have identical voting, dividend, liquidation, and other relative rights, preferences, limitations, and terms and conditions, except that: (1) each class has a different designation, (2) each class of shares bears any expenses attributable to a class as set forth in the Plan and the relevant Prospectus, (3) each class has exclusive voting rights on any matter submitted to shareholders that relates solely to it or its distribution and service plan adopted under Rule 12b-1, if any, and (4) each class has separate voting rights on any matter submitted to shareholders in which the interests of one class differ from the interests of any other class. In addition, each class has the particular features described below. The differences among the classes of the Fund are subject to change by action of the Board of Directors of the Fund and to the extent permitted by the 1940 Act and the Fund's articles of incorporation and bylaws. All issued and outstanding shares of the Fund are fully paid and nonassessable. Shares have no preemptive rights. Fractional shares have the same rights proportionately as full shares. The shares of the Fund do not have cumulative voting rights, which means that the holders of more than 50 percent of the shares of the Fund, voting for the election of directors, can elect all the directors.

Any reference to the phrase "vote of a majority of the outstanding voting securities of the Fund" means the vote at any meeting of shareholders of a Fund of (i) 67 percent or more of the shares present or represented by proxy at the meeting, if the holders of more than 50 percent of the outstanding shares are present or represented by proxy, or (ii) more than 50 percent of the outstanding shares, whichever is less.

36

DISTRIBUTION AND SERVICING

DISTRIBUTION PLAN

The Directors have approved a plan pursuant to Rule 12b-1 under the 1940 Act (the "12b-1 Plan") for the Fund's Class A, B, C, D, G and R shares. Under the 12b-1 Plan, the Fund pays CMD a monthly distribution fee at an annual rate of up to 0.50% of the Fund's net assets attributed to Class R shares.

The monthly distribution fees shall be used by CMD to cover expenses and activities primarily intended to result in the sale of Fund shares. These expenses and activities may include but are not limited to: (a) direct out-of-pocket promotional expenses incurred by CMD in advertising and marketing Fund shares; (b) expenses incurred in connection with preparing, printing, mailing, and distributing or publishing advertisements and sales literature; (c) expenses incurred in connection with printing and mailing prospectuses and Statements of Additional Information to other than current shareholders; (d) periodic payments or commissions to one or more securities dealers, brokers, financial institutions and other industry professionals ("Service Organizations") with respect to the Fund's shares beneficially owned by customers for whom the Service Organization is the shareholder of record; (e) the direct and indirect cost of financing the payments or expenses included in
(a) and (d) above; or (f) such other services as may be construed by any court or governmental agency or commission, including the SEC, to constitute distribution services under the 1940 Act or rules and regulations thereunder.

Shareholder Liaison Services may include the following services provided by FSFs: (a) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (b) processing dividend payments; and (d) providing periodic mailings to customers.

CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to FSFs and for certain other purposes. Since the distribution fees are payable regardless of CMD's expenses, CMD may realize a profit from the fees. The 12b-1 Plan authorizes the Advisor to make payments out of its own funds for distribution or services costs.

TERMS OF THE DISTRIBUTION PLAN

CMD has advised the Fund that the Distribution Plan could be significant factors in the growth and retention of the Fund's assets, resulting in a more advantageous expense ratio, increased investment flexibility and a greater ability to attract and retain research and portfolio management talent, which could benefit Class R of the Fund's shareholders. The Distribution Plan will continue in effect from year to year so long as their continuance is specifically approved at least annually by a vote of the Directors, including the Directors who are not interested persons of the Fund and have no direct or indirect financial interest in the operation of the Distribution Plan or in any related agreements ("Independent Directors"), and, with respect to the Distribution Plan, cast in person at a meeting called for the purpose. All material amendments of the Distribution Plan must be approved by the Directors in the manner provided in the foregoing sentence. The Distribution Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares. The Distribution Plan may be terminated at any time by vote of a majority of the Independent Directors or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Distribution Plan will only be effective if the selection and nomination of the Directors who are not interested persons of the Funds is effected by such Independent Directors.

Class R shares of the Fund have paid no 12b-1 fees as of the date of this Statement of Additional Information.

37

PURCHASE, REDEMPTION AND PRICING OF SHARES

PURCHASES AND REDEMPTIONS

A detailed discussion of how you may purchase, redeem and exchange each class of shares in the Fund is discussed in the Prospectus.s. The following information and policies are supplemental to that found in the applicable Prospectus.

The Fund will generally accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to a Fund before the Fund processes that day's transactions. If the FSF fails to transmit before a Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close regular trading on the New York Stock Exchange ("Exchange") on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of a Fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank. Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs. Class R shares will be offered without a sales charge.

Checks presented for the purchase of shares of a Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gifts checks, credit card convenience checks, credit cards, cash and bank counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described in the Prospectus. Certificates will not be issued. Shareholders may send any certificates to CMS for deposit to their account.

In addition to the commissions specified in the Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with

38

shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

PLEASE CONTACT YOUR FSF OR INTERMEDIARY FOR DETAILS ABOUT PAYMENTS IT MAY RECEIVE.

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of the Fund may be purchased through the Automatic Investment Plan. Preauthorized monthly electronic funds transfers for a fixed amount of at least $50 ($25 for Individual Retirement Accounts ("IRAs")) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds from the transfer. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING. The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any mutual fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your Fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same class of shares by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes. You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of Funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

41

TAX-SHELTERED RETIREMENT PLANS. CMD offers prototype tax-qualified plans, including Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company serves as Trustee of CMD prototype plans and charges a $20 annual fee. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in non-CMD prototype Retirement Plans (other than IRAs) also are charged a $20 annual fee unless the plan maintains an omnibus account with CMS. Participants in CMD prototype Plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a CMD IRA Rollover account in any Fund, or if the Plan maintains an omnibus account.

Consultation with a competent financial and tax advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification number available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

HOW TO SELL SHARES

Shares may also be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction or stock power form to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable CDSC) next calculated after a Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may required for sales by corporations, agents, fiduciaries, surviving joint owners and individual retirement account holders and other legal entities. Call CMS for more information at 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price. FSFs are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

42

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of duplicative sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

The Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in street name must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-345-6611 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00 p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account, or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address and account number. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions may apply to retirement plan accounts.

NON CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of the Fund's net asset value, the Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

DISTRIBUTIONS

Distributions are invested in additional shares of the same class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by CMS is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) distributed by CMD on the basis of the NAVs per share at the time of exchange. The prospectus of each Fund describes its investment objective and policies, and shareholders should obtain a prospectus and consider these objectives and policies carefully before requesting an exchange. Shares of certain of these funds are not available to residents of all states. Consult CMS before requesting an exchange.

43

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

The Fund also reserves the right to close a shareholder account if the shareholder's actions are deemed to be detrimental to the Fund or its shareholders, including, without limitation, violating the exchange policy set forth in its Prospectus. If the Fund redeems shares, payment will be made promptly at the current net asset value. A redemption may result in a realized capital gain or loss.

PRICING OF SHARES

The net asset value ("NAV") per share of the Fund is determined by the Advisor, under procedures approved by the directors, as of the close of regular trading (normally 4:00 p.m. New York time) on each day the NYSE is open for business and at other times determined by the directors. The NAV per share is computed by dividing the value of all assets of the Fund, less its liabilities, by the number of shares outstanding.

The Fund may suspend the determination of the NAV of a Fund and the right of redemption for any period (1) when the NYSE is closed, other than customary weekend and holiday closings, (2) when trading on the NYSE is restricted, (3) when an emergency exists as a result of which sale of securities owned by the Fund is not reasonably practicable or it is not reasonably practicable for the Fund to determine the value of the Fund's assets, or (4) as the SEC may by order permit for the protection of security holders, provided the Fund complies with rules and regulations of the SEC, which govern as to whether the conditions prescribed in (2) or (3) exist. The NYSE observes the following holidays: New Year's Day, Martin Luther King, Jr.'s Birthday, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.

For purposes of calculating the NAV of the Fund's shares, the following procedures are utilized whenever applicable. The Fund's equity securities are valued at the last sale price on the securities exchange or national securities markets at which such securities primarily are traded. Securities not listed on an exchange or national securities market, or securities in which there were no transactions, are valued using the last bid price. Each Fund purchasing debt securities uses market value to value such securities as quoted by an independent pricing service, dealers who are market makers in the securities or by procedures and guidelines approved by the Fund's Board of Directors. Market values are generally based on the average of bid and ask prices, or by reference to other securities with comparable ratings, interest rates and maturities. Certain securities for which daily market quotations are not readily available, or for which the Advisor believes the quotations do not accurately value the security in question, may be fair valued by the Advisor, pursuant to guidelines established by the Fund's Board of Directors.

The value of assets or liabilities initially expressed in a foreign currency will, on a daily basis, be converted into U.S. dollars. Foreign securities will generally be valued based upon the most recent closing price on their principal exchange, or based upon the most recent price obtained by the Fund, if the security is not priced on an exchange, even if the close of that exchange or price determination is earlier than the time of the Fund's NAV calculation. In the case of such foreign security, if an event that is likely to affect materially the value of a portfolio security occurs between the time the foreign price is determined and the time the Fund's NAV is calculated, it may be necessary to value the security in light of that event.

44

CUSTODIAN

State Street Bank & Trust Company (the "Custodian"), 2 Avenue de Lafayette, Boston, Massachusetts 02111-2900 acts as the Funds' general custodian, for both domestic and foreign securities. The Custodian holds securities and cash of the Funds, receives and pays for securities purchased, delivers against payment securities sold, receives and collects income from investments, makes all payments covering expenses of the Funds, and performs other administrative duties, all as directed by authorized officers of the Advisor. The Custodian does not exercise any supervisory function in the purchase and sale of portfolio securities or payment of dividends.

Portfolio securities purchased in the United States are maintained in the custody of the Custodian. Portfolio securities purchased outside the United States by the Fund are maintained in the custody of foreign banks, trust companies, or depositories that have sub-custodian arrangements with the Custodian (the "foreign sub-custodians"). Each of the domestic and foreign custodial institutions that may hold portfolio securities of the Fund has been approved by the Board of Directors of the Fund or, in the case of foreign securities, by the Custodian, as a delegate of the Board of Directors, all in accordance with regulations under the 1940 Act.

The Advisor determines whether it is in the best interest of the Fund and their shareholders to maintain the Fund's assets in each of the countries in which the Fund invests ("Prevailing Market Risk"). The review of Prevailing Market Risk includes an assessment of the risk of holding a Fund's assets in a country, including risks of expropriation or imposition of exchange controls. In evaluating the foreign sub-custodians, the Board of Directors, or its delegate, will review the operational capability and reliability of the foreign sub-custodian. With respect to foreign investments and the selection of foreign sub-custodians, however, there is no assurance that the Fund, and the value of its shares, will not be adversely affected by acts of foreign governments, financial or operational difficulties of the foreign sub-custodians, difficulties and cost of obtaining jurisdiction over, or enforcing judgments against, the foreign sub-custodians, or the application of foreign law to a Fund's foreign sub-custodial arrangement. Accordingly, an investor should recognize that the risks involved in holding assets abroad are greater than those associated with investing in the United States.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

PricewaterhouseCoopers LLP ("PwC"), 125 High Street, Boston, Massachusetts, 02110, is the Fund's Independent Registered Public Accounting Firm. In addition to examining the financial statements of the Fund, PwC assists in the review of the tax returns of the Fund and in certain other matters.

TAXES

FEDERAL INCOME TAXES

The Fund intends and expects to meet continuously the tests for qualification as a regulated investment company under Part I of Subchapter M of the Code. The Fund believes it satisfies the tests to qualify as a regulated investment company. If the Fund were to fail to qualify as a "regulated investment company" in any year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and distributions would generally be taxable as ordinary dividend income to the shareholders.

To qualify as a regulated investment company for any taxable year, the Fund must, among other things:

(a) derive at least 90 percent of its gross income from dividends; interest; payments with respect to securities loans; gains from the sale or other disposition of stock, securities, or foreign currencies; other income
(including but not limited to gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities, or currencies; or net income from an interest in qualified publicly traded partnerships (the "90 Percent Test"); and

45

(b) diversify its holdings so that, at the end of each quarter of its taxable year, (i) 50 percent or more of the value of the assets of the Fund consists of cash, government securities, securities of other regulated investment companies and other securities limited, in respect of any one issuer of such other securities, to an amount not greater than 5 percent of the value of the assets of the Fund and 10 percent of the outstanding voting securities of such issuer, and (ii) not more than 25 percent of the value of the assets of the Fund is invested in either the securities (other than government securities or securities of other regulated investment companies) of any one issuer or of two or more issuers that the Fund "controls" within the meaning of Section 851 of the Code and that meet certain requirements or the securities of one or more qualified publicly traded partnerships (the "Diversification Test"). In addition, a Fund must file, or have filed, a proper election with the Internal Revenue Service.

Part I of Subchapter M of the Code will apply to the Fund during a taxable year only if it meets certain additional requirements. Among other things, the Fund must: (a) have a deduction for dividends paid (without regard to capital gain dividends and exempt interest dividends) at least equal to the sum of 90 percent of its investment company taxable income (computed without any deduction for dividends paid) and 90 percent of its tax-exempt interest (net of expenses attributable to such interest), and (b) either (i) have been subject to Part I of Subchapter M for all taxable years ending on or after November 8, 1983 or
(ii) as of the close of the taxable year have no earnings and profits accumulated in any taxable year to which Part I of Subchapter M did not apply.

A regulated investment company that meets the requirements described above is taxed only on its "investment company taxable income," which generally equals the undistributed portion of its ordinary net income and any excess of net short-term capital gain over net long-term capital loss. In addition, any excess of net long-term capital gain over net short-term capital loss that is not distributed as a "capital gain dividend" is taxed to the Fund at corporate capital gain tax rates. The policy of the Fund is to apply capital loss carry-forwards as a deduction against future capital gains before making a capital gain distribution to shareholders. Under rules that are beyond the scope of this discussion, certain capital losses and certain net foreign currency losses resulting from transactions occurring in November and December of a taxable year may be taken into account either in that taxable year or in the following taxable year.

If any net capital gains (i.e. the excess of net long-term capital gains over net short-term capital losses) are retained by the Fund, requiring federal income taxes to be paid thereon by the Fund, the Fund may elect to treat such capital gains as having been distributed to shareholders. In the case of such an election, shareholders will be taxed on such amounts as long-term capital gains, will be able to claim their proportional share of the federal income taxes paid by the Fund on such gains as credits against their own federal income tax liabilities, and generally will be entitled to increase the adjusted tax basis of their shares in the Fund by the differences between their pro rata shares of such gains and their tax credits.

SPECIAL ASPECTS OF 90 PERCENT TEST WITH RESPECT TO FOREIGN CURRENCY. For purposes of the 90 Percent Test, foreign currency gains that are not directly related to the Fund's principal business of investing in stocks or securities (or options and futures with respect to stock or securities) may be excluded from qualifying income by regulation. No such regulations, however, have been issued.

Unless an exception applies, the Fund may be required to recognize some income with respect to foreign currency contracts under the mark-to-market rules of Section 1256 even though that income is not realized. Special rules under Sections 1256 and 988 of the Code determine the character of any income, gain, or loss on foreign currency contracts.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts, and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale, and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund.

Certain of the Fund's hedging activities (including its transactions, if any, in foreign currencies or foreign currency-denominated instruments) are likely to produce a difference between its book income and its taxable income. If the Fund's book income exceeds its taxable income, the distribution (if any) of such excess will be treated as (i) a dividend to the extent of the Fund's remaining earnings and profits (including earnings and profits arising from tax-exempt income), (ii) thereafter as a return of capital to the extent of the recipient's basis in the shares, and (iii) thereafter as gain from the sale or exchange of a capital asset. If the Fund's book income is less than its taxable income, the Fund could be required to make distributions exceeding book income to qualify as a regulated investment company that is accorded special tax treatment.

OTHER FUNDS. Shareholders of the Fund are taxed on distributions of net investment income, or of any excess of net short-term capital gain over net long-term capital loss, as ordinary income. Income distributions to corporate shareholders from the Fund may qualify,

46

in whole or part, for the federal income tax dividends-received deduction, depending on the amount of qualifying dividends received by the Fund. Qualifying dividends may include those paid to the Fund by domestic corporations but do not include those paid by foreign corporations. The dividends-received deduction equals 70 percent of qualifying dividends received from the Fund by a shareholder, and is subject to a holding period requirement. In addition, qualifying dividends are includable in adjusted current earnings for purposes of computing the corporate alternative minimum tax.

GENERAL CONSIDERATIONS. Distributions from the Fund will be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions properly designated by any Fund as representing the excess of net long-term capital gain over net short-term capital loss are taxable to shareholders at the applicable long-term capital gains rate, regardless of the length of time the shares of the Fund have been held by shareholders. For noncorporate taxpayers, the highest rate that applies to long-term capital gains is lower than the highest rate that applies to ordinary income; however, as a result of 2003 legislation, for taxable years beginning on or before December 31, 2008 qualified dividend income distributions to individuals generally are taxed at the same rate that applies to long-term capital gains, subject to holding period requirements with respect to shareholders and the Fund as well as other requirements. For this purpose, long-term capital gain rates apply to the extent that the Fund receives dividends from domestic or qualifying foreign corporations and the Fund meets holding period and other requirements. Generally, a dividend received from a foreign corporation will not be treated as qualified dividend income if the foreign corporation is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company or, for taxable years of foreign corporations beginning on or before December 31, 2004, as a foreign personal holding company or a foreign investment company. If the aggregate qualified dividends received by the Fund during any taxable year are 95 percent or more of its gross income, then 100 percent of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss. Any loss that is realized and allowed on redemption of shares of the Fund six months or less from the date of purchase of the shares and following the receipt of a capital gain dividend will be treated as a long-term capital loss to the extent of the capital gain dividend. For this purpose, Section 852(b)(4) of the Code contains special rules on the computation of a shareholder's holding period.

Long term capital gains rates have been temporarily reduced, in general, to 15 percent, with lower rates applying to taxpayers in the 10-percent and 15-percent rate brackets for taxable years beginning on or before December 31, 2008.

The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares will be treated as long-term capital gain if the shares have been held for more than 12 months. Otherwise the gain on the sale, exchange or redemption of shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term capital loss if the shares have been held more than 12 months, and otherwise as a short-term capital loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly-purchased shares will be adjusted to reflect the disallowed loss.

Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of capital. Such distributions are likely to occur in respect of shares purchased at a time when the Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when the Fund's net asset value also reflects unrealized losses. A distribution may be taxable to a shareholder even if the distribution reduces the net asset value of the shares held below their cost (and is in an economic sense a return of the shareholder's capital). This tax result is most likely when shares are purchased shortly before an annual distribution of capital gains or other earnings.

Distributions of taxable net investment income and net realized capital gains will be taxable as described above, whether paid in shares or in cash. Each distribution is accompanied by a brief explanation of the form and character of the distribution. Within 60 days after the close of each calendar year, the Fund issues to each shareholder a statement of the federal income tax status of all distributions, including a statement of the prior calendar year's distributions which the Fund has designated to be treated as long-term capital gain.

Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the federal AMT.

47

Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

The Fund is generally required to obtain from its shareholders a certification of the shareholder's taxpayer identification number and certain other information. The Fund generally will not accept an investment to establish a new account that does not comply with this requirement. With respect to amounts paid through 2010, if a shareholder fails to certify such number and other information, or upon receipt of certain notices from the Internal Revenue Service, the Fund may be required to withhold 28 percent of any reportable interest or dividends, or redemption proceeds, payable to the shareholder, and to remit such sum to the Internal Revenue Service, for credit toward the shareholder's federal income taxes. The backup withholding rate will be 31 percent for amounts paid after December 31, 2010. A shareholder's failure to provide a social security number or other tax identification number may subject the shareholder to a penalty of $50 imposed by the Internal Revenue Service. In addition, that failure may subject the Fund to a separate penalty of $50. This penalty will be charged against the shareholder's account, which will be closed. Closure of the account may result in a capital gain or loss.

If the Fund declares a dividend in October, November, or December payable to shareholders of record on a certain date in such a month and pays the dividend during January of the following year, the shareholders will be taxed as if they had received the dividend on December 31 of the year in which the dividend was declared. Thus, a shareholder may be taxed on the dividend in a taxable year prior to the year of actual receipt.

A special tax may apply to the Fund if it fails to make enough distributions during the calendar year. The required distributions for each calendar year generally equal the sum of (a) 98 percent of the ordinary income for the calendar year plus (b) 98 percent of the capital gain net income for the one-year period that ends on October 31 during the calendar year (or for the calendar year itself if the Fund so elects), plus (c) an adjustment relating to any shortfall for the prior taxable year. If the actual distributions are less than the required distributions, a tax of 4 percent applies to the shortfall.

The Code allows the deduction by certain individuals, trusts, and estates of "miscellaneous itemized deductions" only to the extent that such deductions exceed 2 percent of adjusted gross income. The limit on miscellaneous itemized deductions will not apply, however, with respect to the expenses incurred by any "publicly offered regulated investment company." The Fund believes that it is a publicly offered regulated investment company because its shares are continuously offered pursuant to a public offering (within the meaning of
Section 4 of the Securities Act of 1933, as amended). Therefore, the limit on miscellaneous itemized deductions should not apply to expenses incurred by any of the Fund.

The Fund may purchase zero coupon bonds (or other discounted debt securities) and payment-in-kind ("PIK") bonds. With respect to zero coupon bonds, the Fund recognizes original-issue-discount income ratably over the life of the bond even though the Fund receives no payments on the bond until the bond matures. With respect to PIK bonds, the Fund recognizes interest income equal to the fair market value of the bonds distributed as interest. Because the Fund must distribute 90 percent of its income to remain qualified as a registered investment company, the Fund may be forced to liquidate a portion of its portfolio (possibly at a time when it is not advantageous to do so) to generate cash to distribute to its shareholders with respect to original-issue-discount income from zero coupon bonds and interest income from PIK bonds.

The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned.

FOREIGN INCOME TAXES

The Mid Cap Growth Fund may invest in foreign securities. Foreign countries may impose income taxes, generally collected by withholding, on foreign-source dividends and interest paid to a Fund. These foreign taxes will reduce a Fund's distributed income and a Fund's return. The Fund generally expects to incur, however, no foreign income taxes on gains from the sale of foreign securities.

The United States has entered into income tax treaties with many foreign countries to reduce or eliminate the foreign taxes on certain dividends and interest received from corporations in those countries. The Fund intends to take advantage of such treaties where possible. It is impossible to predict with certainty the effective rate of foreign taxes that will be paid by the Fund since the amount invested in particular countries will fluctuate and the amounts of dividends and interest relative to total income will fluctuate.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such

48

shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

INVESTMENT IN PASSIVE FOREIGN INVESTMENT COMPANIES. Investment by the Fund in certain "passive foreign investment companies" ("PFICs") could subject the Fund to a U.S. federal income tax (including interest charges) on distributions received from the company or on proceeds received from the disposition of shares in the company, which tax cannot be eliminated by making distributions to fund shareholders. However, the Fund may be able to elect to treat a PFIC as a "qualified electing fund," in which case the Fund will be required to include its share of the company's income and net capital gain annually, regardless of whether it receives any distribution from the company. Alternatively, the Fund may make an election to mark the gains (and, to a limited extent, losses) in such holdings "to the market" as though it had sold and repurchased its holdings in those PFICs on the last day of the Fund's taxable year. Such gains and losses are treated as ordinary income and loss. The qualified electing fund and mark-to-market elections may have the effect of accelerating the recognition of income (without the receipt of cash) and increasing the amount required to be distributed for the Fund to avoid taxation. Making either of these elections therefore may require the Fund to liquidate other investments (including when it is not advantageous to do so) in order to meet its distribution requirement, which also may accelerate the recognition of gain and affect the Fund's total return. It is anticipated that any taxes on the Fund with respect to investments in PFICs would be insignificant.

49

INVESTMENTS IN REAL ESTATE INVESTMENT TRUSTS

The Fund may invest in REITs that hold residual interests in real estate mortgage investment conduits ("REMICs"). Under Treasury regulations that have not yet been issued, but may apply retroactively, certain income from a REIT that is attributable to the REIT's residual interest in a REMIC (referred to in the Code as an "excess inclusion") will be subject to federal income tax in all events. These regulations are also expected to provide that excess inclusion income of a regulated investment company will be allocated to shareholders of the regulated investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest directly.

In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on unrelated business income, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign shareholder, will not qualify for any reduction in U.S. federal withholding tax. In addition, if at any time during any taxable year a "disqualified organization" (as defined in the Code) is a record holder of a share in a regulated investment company, then the regulated investment company will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the highest federal income tax rate imposed on corporations.

STATE INCOME TAXES

Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their fund shares and distributions and redemption proceeds received from the Fund.

ADDITIONAL INFORMATION

The foregoing summary and the summary included in the Prospectus under "Distributions and Taxes" of tax consequences of investment in the Fund are necessarily general and abbreviated. No attempt has been made to present a complete or detailed explanation of tax matters. Furthermore, the provisions of the statutes and regulations on which they are based are subject to change, prospectively or retroactively, by legislative or administrative action. Local taxes are beyond the scope of this discussion. Prospective investors in the Fund are urged to consult their own tax advisors regarding specific questions as to federal, state, or local taxes.

Recent Tax Shelter Reporting Regulations. Under recently promulgated Treasury regulations, if a shareholder recognizes a loss under Section 165 of the Code with respect to shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

This discussion applies only to general U.S. shareholders. Foreign investors and U.S. shareholders with particular tax issues or statuses should consult their own tax advisors regarding the special rules that may apply to them.

APPENDIX I

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

52

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have

53

interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

54

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

55

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

56

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

57

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

58

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

59

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

- Potential competitiveness

- Regulatory developments

- Current and potential returns

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

64

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

It is expected that the Fund will be reorganized as a series of Columbia Funds Series Trust I, a Massachusetts business trust, into which all of the retail Columbia funds are expected to be reorganized.

INVESTMENT GOALS AND POLICIES

Part 1 of this SAI contains additional information concerning, among other things, the investment policies of the Fund. Part 2 contains additional information about the following securities and investment techniques that may be utilized by the Fund:

Repurchase Agreements
Futures Contracts and Related Options Small Companies
Money Market Instruments

Other Investment Companies

Except as indicated below under "Fundamental Investment Policies," the Fund's investment policies are not fundamental and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or
(2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

b


The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 50% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies which may be changed without a shareholder vote, the Fund may not:

1. Invest more than 15% of its net assets in illiquid assets;

2. Have a short sales position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and

3. Purchase securities on margin, but the Fund may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For purposes of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

FUND CHARGES AND EXPENSES

Effective November 1, 2004, under the Fund's management contracts, the Fund pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of:

Average Daily Net Assets                               Rate
------------------------                              -----
Net assets under $500 million                         0.950%

c

Additionally, effective November 1, 2005, the Fund entered into an Administrative Agreement with the Advisor pursuant to which the Advisor performs certain administrative services to the Fund. The Advisor has delegated responsibility for certain administrative services to State Street Corporation.

Prior to November 1, 2004, under the Fund's Management Agreement with the Advisor, effective November 1, 2003, the Fund paid the Advisor a monthly fee based on average daily net assets at the following annual rates: 0.95% up to $1 billion, 0.90% of the next $500 million and 0.85% thereafter. Prior to November 1, 2003, the Fund paid the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of 1.15%. Effective November 1, 2003, the Board of Trustees eliminated the administration fee for the Fund. Prior to November 1, 2003, the Fund paid the Administrator, under an Administration Agreement with the Administrator, a monthly fee at the annual rate of 0.25% of the average daily net assets of the Fund.

The Advisor provides certain pricing and bookkeeping services to the Fund. Effective November 1, 2005, the Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Fund will continue to receive substantially the same pricing, bookkeeping and administrative services as it currently receives under the Agreement. The Advisor and State Street Bank and Trust Company will continue to provide these services to the Fund. For services provided under the Pricing and Bookkeeping Agreement, the Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus 0.015% of the Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. For services provided under the Administrative Agreement, the Fund will pay the Advisor an annual fee equal to $0. The Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

For periods prior to November 1, 2005, the Fund paid the Advisor fees under a similar pricing and bookkeeping agreement a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

- an annual flat fee of $10,000, paid monthly; and

- in any month that the Fund had average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

The Fund reimbursed the Advisor for all out-of-pocket expenses and charges, including all fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Fund has entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to the Fund (and will continue to retain Boston Financial Data Services, Inc. to assist it) for a reduced fee. The new fee is $15.23 per account per annum, payable monthly. In addition, the Fund may pay CMS the fees and expenses it pays to third-party dealer firms that maintain omnibus accounts with the Fund, subject to a cap equal to 0.11% of the Fund's net assets represented by the account. The Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Fund.

COMPENSATION

As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

Jasmine Huang            MSCI China GD       Lipper China Region Category

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

The Fund offers four classes of shares--Class A, Class B, Class C and Class Z. The Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan ("Plan") for the Fund pursuant to Rule 12b-1 under the 1940 Act for each class except for Class Z shares. Under the Fund's Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.25% of the Fund's net assets attributed to Class A, B and C shares. The Fund also pays CMD monthly a distribution fee at an annual rate of 0.75% of the average daily net assets attributed to its Class B and Class C shares. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms ("FSFs") and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Fund to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirectly financing the distribution of the Fund's shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of the Fund's assets, resulting in a more advantageous expense ratio and increased investment flexibility that could benefit each class of the Fund's shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan ("Independent Trustees"), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares, and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value subject to a CDSC if redeemed within six years after purchase. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs and initial sales charges are described in the Prospectuses.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

j


Eight years after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares, having an equal value, which are not subject to a distribution fee.

SALES-RELATED EXPENSES (dollars in thousands) of CMD relating to Class A, B, and C shares of the Fund were:

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, , Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

1

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad- based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

2

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

3

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets.

Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

4

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

5

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

6

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non- appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

7

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

8

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

9

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

10

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

11

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

12

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv)

13

unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

14

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

15

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

16

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

17

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

18

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

19

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

20

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

21

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of
(c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax- exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

22

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

23

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

24

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

25

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

26

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

27

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

Approving the Investment Advisory Contract

In determining to approve the most recent annual extension of a Fund's management agreement, the Trustees met over the course of the year with the relevant investment advisory personnel from the Advisor and considered information provided by the Advisor relating to the education, experience and number of investment professionals and other personnel providing services under that agreement. See "Managing the Fund" in each Fund's Prospectus and "Trustees and Officers" in this SAI. The Trustees also took into account the time and attention devoted by senior management to the Funds and the other funds in the Fund Complex. The Trustees evaluated the level of skill required to manage the Funds and concluded that the human resources devoted by the Advisor to the Funds were appropriate to fulfill effectively the Advisor's duties under the agreement. The Trustees also considered the business reputation of the Advisor and its financial resources, and concluded that the Advisor would be able to meet any reasonably foreseeable obligations under the agreement.

The Trustees received information concerning the investment philosophy and investment process applied by the Advisor in managing the Funds. See "Principal Investment Strategies" and "Principal Investment Risks" in the Funds' Prospectuses. In this connection, the Trustees considered the Advisor's in-house research capabilities as well as other resources available to the Advisor's personnel, including research services available to the Advisor as a result of securities transactions effected for the Funds and other investment advisory clients. The Trustees concluded that the Advisor's investment process, research capabilities and philosophy were well suited to each Fund, given each Fund's investment goal(s) and policies.

The Trustees considered the scope of the services provided by the Advisor to the Funds under the agreement relative to services provided by third parties to other mutual funds. See "Fund Charges and Expenses" and "Management of the Funds
- The Management Agreement". The Trustees concluded that the scope of the Advisor's services to the Funds was consistent with the Funds' operational requirements, including, in addition to its investment goal, compliance with each Fund's investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services provided by the Advisor to the Funds. The Trustees evaluated the Advisor's record with respect to regulatory compliance and compliance with the investment policies of each Fund. The Trustees also evaluated the procedures of the Advisor designed to fulfill the Advisor's fiduciary duty to the Funds with respect to possible conflicts of interest, including the Advisor's code of ethics (regulating the personal trading of its officers and employees) (see "Management of the Funds - Code of Ethics"), the procedures by which the Advisor allocates trades among its various investment advisory clients and the record of the Advisor in these matters. The Trustees also received information concerning standards of the Advisor with respect to the execution of portfolio transactions. See "Management of the Funds
- Portfolio Transactions."

The Trustees considered the Advisor's management of non-advisory services provided by persons other than the Advisor by reference, among other things, to each Fund's total expenses and the reputation of each Fund's other service providers. See "Your Expenses" in each Fund's Prospectus(es). The Trustees also considered information provided by third parties relating to each Fund's investment performance relative to its performance benchmark(s), relative to other similar funds managed by the Advisor and relative to funds managed similarly by other advisors. The Trustees reviewed performance over various periods, including each Fund's one, five and ten year calendar year periods and/or the life of the Fund, as applicable (See "Performance History" in the Fund's Prospectuses), as well as factors identified by the Advisor as contributing to each Fund's performance. See each Fund's most recent annual and semi-annual reports. The Trustees concluded that the scope and quality of the Advisor's services was sufficient to merit reapproval of the agreement for another year.

In reaching that conclusion, the Trustees also gave substantial consideration to the fees payable under the agreement. The Trustees reviewed information concerning fees paid to investment advisors of similarly-managed funds. The Trustees also considered the fees of the Funds as a percentage of assets at different asset levels and possible economies of scale to the Advisor. The Trustees evaluated the Advisor's profitability with respect to the Funds, concluding that such profitability appeared to be generally consistent with levels of profitability that had been determined by courts to be "not excessive." For these purposes, the Trustees took into account not only the actual dollar amount of fees paid by the Funds directly to the Advisor, but also so-called "fallout benefits" to the Advisor such as reputational value derived from serving as investment Advisor to the Funds and the research services available to the Advisor by reason of brokerage commissions generated by each Fund's turnover. In evaluating the Funds' advisory fees, the Trustees also took into account the complexity of investment management for the Funds relative to other types of funds. Based on challenges associated with less readily available market information about foreign issuers and smaller capitalization companies, limited liquidity of certain securities, and the specialization required for focused funds, the Trustees concluded that generally greater research intensity and trading acumen is required for equity funds, and for international or global funds, as compared to funds investing, respectively, in debt obligations or in U.S.

35

issuers. Similarly, the Trustees concluded that, generally, small capitalization equity funds and focused funds including state specific municipal funds, require greater intensity of research and trading acumen than larger capitalization or more diversified funds. See "The Fund" in each Fund's Prospectus.

Based on the foregoing, the Trustees concluded that the fees to be paid the Advisor under the advisory agreement were fair and reasonable, given the scope and quality of the services rendered by the Advisor.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000, an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

36

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

37

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions

38

pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate

39

solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

40

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                          FREQUENCY OF
TYPE OF FUND                INFORMATION PROVIDED           DISCLOSURE           DATE OF WEB POSTING
------------                --------------------          ------------          -------------------
Equity Funds        Full portfolio holdings information.     Monthly    30 calendar days after month-end.
Fixed Income Funds  Full portfolio holdings information.    Quarterly   60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These

41

service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund and Columbia Newport Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET
FUND))

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

42

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

43

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for

46

sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares; (ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

47

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at NAV to the following individuals, whether currently employed or retired: Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub- advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds

48

spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

49

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

50

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under
Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

51

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS)
(Available only on the Class A and Z shares of certain Funds)

Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause

52

Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Longer than six years                 None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

53

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund

Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares.

To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

55

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

57

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

58

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

59

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality

Prime-2 Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

60

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

62

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

63

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non- independence);

64

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

65

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

66

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows: Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

67

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

68

8. Investment Company Matters

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's

72

clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987. Each Fund is an open-end, management investment company representing the entire interest in a separate series of the Trust and is a diversified series of the Trust. Each Fund is the successor to a separate series of the Galaxy Fund, a Massachusetts business trust organized on March 31, 1986. On November 18, 2002, November 25, 2002 and December 9, 2002, the series of the Galaxy Fund to which the Funds succeeded (the "Predecessor Funds") were reorganized as separate series of the Trust. Class A shares of the Funds were issued in exchange for Prime A Shares of the Predecessor Funds, Class B shares of the Funds were issued in exchange for Prime B Shares of the Predecessor Funds, Class T shares of the Funds were issued in exchange for Retail A Shares of the Predecessor Funds, Class G shares of the Funds were issued in exchange for Retail B Shares of the Predecessor Funds and Class Z shares of the Funds were issued in exchange for Trust Shares of the Predecessor Funds. (Prime A and B shares, Retail A and B shares and Trust Shares together are referred to herein as to the "Predecessor Classes"). Information provided with respect to each Fund for periods prior to such Fund's inception relates to the Fund's Predecessor Fund. Further, information provided with respect to each class of each Fund relates to the Predecessor classes of such class.

The Asset Allocation Fund commenced operations on December 30, 1991; the Growth Fund commenced operations on December 14, 1990; the Value Fund commenced operations on September 1, 1988; the Small Company Fund commenced operations on December 30, 1991; and the Dividend Fund commenced operations on March 4, 1998.

The Common Stock Fund and Small Cap Core Fund commenced operations on December 14, 1992, as separate portfolios (the "Predecessor Large Cap Fund" and "Predecessor Small Cap Fund," respectively, and collectively, the "Predecessor Shawmut Funds") of The Shawmut Funds. On December 4, 1995, the Predecessor Shawmut Funds were

b


reorganized as new portfolios of the Galaxy Fund. Prior to the reorganization, the Predecessor Shawmut Funds offered and sold shares of beneficial interest that were similar to the Galaxy Fund's Trust Shares and Retail A Shares.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the share (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes). Shares of the Funds and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

On February 1, 1996, the name of the Trust was changed to separate "SteinRoe" into two words. The name of the Trust was changed on October 18, 1999, from "Stein Roe Investment Trust" to "Liberty Stein-Roe Investment Trust." On October 13, 2003, the name of the Trust was changed from "Liberty-Stein Roe Investment Trust" to its current name.

It is expected that each Fund will be reorganized as a series of Columbia Funds Series Trust I, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized in 2006.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a particular Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in

d

connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and
(b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and
(b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

NON-FUNDAMENTAL INVESTMENT POLICIES

The following investment limitation with respect to the Funds may be changed by the Board of Trustees without shareholder approval:

8. A Fund may not sell securities short, maintain a short position, or purchase securities on margin, except for such short-term credits as are necessary for the clearance of transactions.

The following investment limitations with respect to the Asset Allocation Fund, Dividend Fund, Value Fund, Growth Fund and Small Company Fund may be changed by the Board of Trustees without shareholder approval:

9. A Fund may not write or sell put options, call options, straddles, spreads or any combination thereof except that (i) each of the Value Fund, Growth Fund and Small Company Fund may, to the extent consistent with its investment objective and policies, write covered call options and purchase and sell other options, and (ii) the Asset Allocation Fund and the Dividend Fund may buy and sell options, including without limit buying or writing puts and calls, based on any type of security, index or currency, including options on foreign exchanges and options not traded on exchanges to the extent permitted by its investment objective and policies.

e


10. A Fund may not purchase securities of companies for the purpose of exercising control.

11. A Fund may not purchase securities of other investment companies except as permitted by the 1940 Act, except that the Dividend Fund may, from time to time, on a temporary basis, invest exclusively in one other investment company similar to the Fund.

The following investment limitation with respect to the Asset Allocation Fund, Dividend Fund, Value Fund, Growth Fund and Small Company Fund may be changed by the Board of Trustees without shareholder approval:

12. A Fund may not invest more than 15% of its net assets in illiquid securities.

The following investment limitations with respect to the Common Stock Fund and Small Cap Core Fund may be changed by the Board of Trustees without shareholder approval:

13. The Funds may not invest more than 15% of their respective net assets in securities subject to restrictions on resale under the Securities Act of 1933 (except for commercial paper issued under Section 4(2) of the Securities Act of 1933 and certain securities which meet the criteria for liquidity as established by the Board of Trustees).

14. Each Fund will limit its investments in other investment companies to not more than 3% of the total outstanding voting stock of any investment company; will invest no more than 5% of its total assets in any one investment company; and will invest no more than 10% of its total assets in investment companies in general. However, these limitations are not applicable if the securities are acquired in a merger, consolidation, reorganization or acquisition of assets.

15. The Funds will purchase the securities of other investment companies only in open market transactions involving only customary broker's commissions. It should be noted that investment companies incur certain expenses such as management fees, and therefore any investment by a Fund in shares of another investment company would be subject to such duplicate expenses.

16. Neither Fund may purchase or retain the securities of any issuer if the officers and Trustees of the Trust or the Advisor, owning individually more than 1/2 of 1% of the issuer's securities, together own more than 5% of the issuer's securities.

17. Neither Fund may purchase or sell interests in oil, gas, or mineral exploration or development programs or leases; except that the Funds may purchase the securities of issuers which invest in or sponsor such programs.

18. Neither Fund may purchase put options on securities, unless the securities are held in the Fund's portfolio and not more than 5% of the value of the Fund's total assets would be invested in premiums on open put option positions.

19. Neither Fund may write call options on securities, unless the securities are held in the Fund's portfolio or unless the Fund is entitled to them in deliverable form without further payment or after segregating cash in the amount of any further payment. Neither Fund may write call options in excess of 5% of the value of its total assets.

20. Neither Fund will invest more than 15% of the value of its respective net assets in illiquid securities, including repurchase agreements providing for settlement in more than seven days after notice, non-negotiable fixed time deposits with maturities over seven days, and certain securities not determined by the Board of Trustees to be liquid.

21. Neither Fund may invest in companies for the purpose of exercising management or control.

22. Neither Fund may invest more than 5% of its net assets in warrants. No more than 2% of this 5% may be warrants which are not listed on the New York Stock Exchange.

With respect to Investment Limitation No. 11 above, the 1940 Act currently prohibits a Fund, subject to certain exceptions, from acquiring the securities of other investment companies if, as a result of such acquisition, (a) the

f


Fund owns more than 3% of the total outstanding voting stock of the investment company; (b) securities issued by any one investment company represent more than 5% of the total assets of the Fund; or (c) securities (other than treasury stock) issued by all investment companies represent more than 10% of the total assets of the Fund.

Each Fund may purchase restricted securities, which are any securities in which the Fund may otherwise invest pursuant to its investment objective and policies but which are subject to restrictions on resale under the federal securities laws. Certain restricted securities may be considered liquid pursuant to guidelines established by the Board of Trustees. To the extent restricted securities are deemed illiquid, each Fund will limit its purchase, together with other securities considered to be illiquid, to 15% of its net assets.

Each of the Growth Fund and Small Company Fund may purchase put options and call options on securities and securities indices. Neither of these Funds may purchase options unless immediately after any such transaction the aggregate amount of premiums paid for put or call options does not exceed 5% of its total assets.

Each of the Value Fund, Growth Fund and Small Company Fund may engage in writing covered call options and may enter into closing purchase transactions with respect to such options. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. The aggregate value of the securities subject to such options written by these Funds may not exceed 25% of the value of such Fund's net assets.

Each of the Asset Allocation Fund, Common Stock Fund, Dividend Fund and Small Cap Core Fund may buy and sell options and futures contracts to manage their exposure to changing interest rates, security prices and currency exchange rates. These Funds may invest in options and futures based on any type of security, index, or currency, including options and futures based on foreign exchanges and options not traded on exchanges. These Funds will not hedge more than 20% of their respective total assets (10% of net assets with respect to the Asset Allocation Fund) by selling futures, buying puts, and writing calls under normal conditions. These Funds will not buy futures or write puts whose underlying value exceeds 20% of their respective total assets (10% of net assets with respect to the Asset Allocation Fund), and will not buy calls with a value exceeding 5% of their respective total assets. These Funds may utilize stock index futures contracts, options, swap agreements, indexed securities, and options on futures contracts for the purposes of managing cash flows into and out of their respective portfolios and potentially reducing transaction costs, subject to the limitation that the value of these futures contracts, swap agreements, indexed securities, and options will not exceed 20% of the Funds' respective total assets (10% of net assets with respect to the Asset Allocation Fund). These Funds will not purchase put options to the extent that more than 5% of the value of their respective total assets would be invested in premiums on open put option positions. In addition, these Funds do not intend to invest more than 5% of the market value of their respective total assets in each of the following: futures contracts, swap agreements, and indexed securities. When one of these Funds enters into a swap agreement, liquid assets of the Fund equal to the value of the swap agreement will be segregated by that Fund. These Funds may not use stock index futures contracts and options for speculative purposes.

As a means of reducing fluctuations in the net asset value of shares of the Asset Allocation Fund, Common Stock Fund, Dividend Fund and Small Cap Core Fund, the Funds may attempt to hedge all or a portion of their respective portfolios through the purchase of listed put options on stocks, stock indices and stock index futures contracts. These options will be used as a form of forward pricing to protect portfolio securities against decreases in value resulting from market factors, such as an anticipated increase in interest rates.

The Asset Allocation Fund, Common Stock Fund, Dividend Fund and Small Cap Core Fund may only: (1) buy listed put options on stock indices and stock index futures contracts; (2) buy listed put options on securities held in their respective portfolios; and (3) sell listed call options either on securities held in their respective portfolios or on securities which they have the right to obtain without payment of further consideration (or have segregated cash in the amount of any such additional consideration). Each of these Funds will maintain its positions in securities, option rights, and segregated cash subject to puts and calls until the options are exercised, closed or

g


expired. Each of these Funds may also enter into stock index futures contracts. A stock index futures contract is a bilateral agreement which obligates the seller to deliver (and the purchaser to take delivery of) an amount of cash equal to a specific dollar amount times the difference between the value of a specific stock index at the close of trading of the contract and the price at which the agreement is originally made. There is no physical delivery of the stocks constituting the index, and no price is paid upon entering into a futures contract.

None of the Asset Allocation Fund, Common Stock Fund, Dividend Fund and Small Cap Core Fund will enter into futures contracts if, immediately thereafter, the sum of its initial margin deposits on open contracts exceeds 5% of the market value of its total assets. Further, these Funds will enter into stock index futures contracts only for bona fide hedging purposes or such other purposes permitted under Part 4 of the regulations promulgated by the Commodity Futures Trading Commission. Also, these Funds may not enter into stock index futures contracts and options to the extent that the value of such contracts would exceed 20% of the Fund's total net assets and may not purchase put options to the extent that more than 5% of the value of (10% of net assets with respect to the Asset Allocation Fund) the Fund's total assets would be invested in premiums on open put option positions.

As one way of managing their exposure to different types of investments, the Asset Allocation Fund, Common Stock Fund, Dividend Fund and Small Cap Core Fund may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors.

Each Fund may buy and sell securities denominated in currencies other than the U.S. dollar, and may receive interest, dividends and sale proceeds in currencies other than the U.S. dollar. The Funds from time to time may enter into foreign currency exchange transactions to convert the U.S. dollar to foreign currencies, to convert foreign currencies to the U.S. dollar and to convert foreign currencies to other foreign currencies.

Each of the Asset Allocation Fund, Value Fund, Growth Fund, Small Cap Core Fund and Small Company Fund may invest in securities issued by other investment companies which invest in high quality, short-term debt securities and which determine their net asset value per share based on the amortized cost or penny-rounding method. The Funds may invest in other investment companies primarily for the purpose of investing their short-term cash which has not yet been invested in other portfolio instruments. However, from time to time, on a temporary basis, each of the Common Stock Fund, Dividend Fund and Small Cap Core Fund may invest exclusively in one other investment company similar to the respective Fund.

All debt obligations, including convertible bonds, purchased by the Asset Allocation Fund, Value Fund, Growth Fund and Small Company Equity Fund are rated investment grade by Moody's (Aaa, Aa, A and Baa) or S&P (AAA, AA, A and BBB), or, if not rated, are determined to be of comparable quality by the Advisor. Debt securities rated Baa by Moody's or BBB by S&P are generally considered to be investment grade securities although they have speculative characteristics and changes in economic conditions or circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case for higher rated debt obligations.

The Common Stock Fund and Small Cap Core Fund may purchase convertible bonds rated Ba or higher by Moody's or BB or higher by S&P or Fitch at the time of investment. Short-term money market instruments purchased by the Common Stock Fund and Small Cap Core Fund must be rated in one of the top two rating categories by a nationally recognized statistical rating agency, such as Moody's, S&P or Fitch.

Subsequent to its purchase by a Fund, an issue of securities may cease to be rated or its rating may be reduced below the minimum rating required for purchase by the Fund. The Board of Trustees or the Advisor may determine that it is appropriate for a Fund to continue to hold the obligation if retention is in accordance with the interests of the particular Fund and applicable regulations of the Securities and Exchange Commission ("SEC"). However, each Fund will sell promptly any security that is not rated investment grade by either S&P or Moody's if such securities exceed 5% of the Fund's net assets.

h


Loans of portfolio securities by the Funds will generally be short-term (except in the case of the Common Stock Fund and Small Cap Core Fund, which may loan their securities on a long-term or short-term basis or both), will be made only to borrowers deemed by the Advisor to be of good standing and only when, in the Advisor's judgment, the income to be earned from the loan justifies the attendant risks. The Funds currently intend to limit the lending of their portfolio securities so that, at any given time, securities loaned by a Fund represent not more than one-third of the value of its total assets.

Each Fund will invest no more than 10% of its net assets in REITs.

Except as stated otherwise, if a percentage limitation is satisfied at the time of investment, a later increase in such percentage resulting from a change in the value of a Fund's portfolio securities generally will not constitute a violation of the limitation. If the value of a Fund's holdings of illiquid securities at any time exceeds the percentage limitation applicable at the time of acquisition due to subsequent fluctuations in value or other reasons, the Board of Trustees will consider what actions, if any, are appropriate to maintain adequate liquidity. With respect to borrowings, if a Fund's asset coverage at any time falls below that required by the 1940 Act, the Fund will reduce the amount of its borrowings in the manner required by the 1940 Act to the extent necessary to satisfy the asset coverage requirement.

Each Fund may follow non-fundamental operating policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectuses and this Statement of Additional Information, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act.

ASSET ALLOCATION FUND

The Asset Allocation Fund may invest up to 25% of its net assets in foreign securities. Such foreign investments may be made directly, by purchasing securities issued or guaranteed by foreign corporations, banks or governments (or their political subdivisions or instrumentalities) or by supranational banks or other organizations, or indirectly, by purchasing American Depositary Receipts ("ADRs") and European Depositary Receipts ("EDRs") (EDRs are also known as Continental Depositary Receipts ("CDRs")). Examples of supranational banks include the International Bank for Reconstruction and Development ("World Bank"), the Asian Development Bank and the InterAmerican Development Bank. Obligations of supranational banks may be supported by appropriated but unpaid commitments of their member countries and there is no assurance that those commitments will be undertaken or met in the future. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI. The Fund may also invest in dollar-denominated high quality debt obligations of U.S. corporations issued outside the United States. The Fund may also buy and sell options and futures contracts, utilize stock index futures contracts, options, swap agreements, indexed securities and options or futures contracts, purchase asset-backed and mortgage-backed securities and enter into foreign currency exchange contracts.

GROWTH FUND

Under normal circumstances, the Growth Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a broadly diversified portfolio of equity securities, primarily common stocks and securities that can be converted into common stocks. Convertible securities purchased by the Growth Fund may include both debt securities and preferred stock. By investing in convertible securities, the Fund will seek the opportunity, through the conversion feature, to participate in the capital appreciation of the common stock into which the securities are convertible. See "Convertible Securities" in Part 2 of this SAI. The Fund may also invest in common stock warrants.

The Fund may invest up to 20% of its total assets in foreign securities, either directly or indirectly through the purchase of ADRs, EDRs and CDRs. In addition, the Fund may invest in securities issued by foreign branches of U.S. banks and foreign banks. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI. The Fund may also purchase put options and call options and write covered call options. See "Options on Securities" in Part 2 of this SAI.

i

VALUE FUND

Under normal circumstances, the Value Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stock, preferred stock (including convertible preferred stock) and debt securities convertible into common stock, mainly those that the Advisor believes to be undervalued. Debt securities convertible into common stock are purchased primarily during periods of relative market instability and are acquired principally for income with the potential for appreciation being a secondary consideration. See "Convertible Securities" in Part 2 of this SAI.

The Fund may also invest up to 20% of its total assets in foreign securities, either directly or indirectly through ADRs, EDRs and CDRs. In addition, the Fund may invest in securities issued by foreign branches of U.S. banks and foreign banks. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI. The Fund may also write covered call options. See "Options on Securities" in Part 2 of this SAI.

COMMON STOCK FUND

Under normal market conditions, the Common Stock Fund will invest at least 80% of its total assets in common stocks, preferred stocks, common stock warrants and securities convertible into common stock. The Fund may purchase convertible securities, including convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities. See "Convertible Securities" in Part 2 of this SAI. The Fund may also buy and sell options and futures contracts and utilize stock index futures contracts, options, swap agreements, indexed securities, and options on futures contracts. See "Options on Securities" and "Futures Contracts and Related Options" in Part 2 of this SAI.

The Fund may invest up to 20% of its total assets in securities of foreign issuers which are freely traded on United States securities exchanges or in the over-the-counter market in the form of ADRs, EDRs, CDRs and Global Depositary Receipts ("GDRs"). Securities of a foreign issuer may present greater risks in the form of nationalization, confiscation, domestic marketability, or other national or international restrictions. As a matter of practice, the Fund will not invest in the securities of foreign issuers if any such risk appears to the Advisor to be substantial. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI.

SMALL CAP CORE FUND

Under normal circumstances, the Small Cap Core Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Index. In addition to common stocks, the Small Cap Core Fund may purchase convertible securities, including convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities. See "Convertible Securities" in Part 2 of this SAI. The Fund may also buy and sell options and futures contracts and utilize stock index futures contracts, options, swap agreements, indexed securities, and options on futures contracts. See "Options on Securities" and "Futures Contracts and Related Options" in Part 2 of this SAI.

The Fund may invest up to 20% of its total assets in securities of foreign issuers which are freely traded on U.S. securities exchanges or in the over-the-counter market in the form of ADRs, EDRs, CDRs and GDRs. Securities of a foreign issuer may present greater risks in the form of nationalization, confiscation, domestic marketability, or other national or international restrictions. As a matter of practice, the Fund will not invest in the securities of a foreign issuer if any such risk appears to the Advisor to be substantial. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI.

j


SMALL COMPANY FUND

In addition to common stocks, the Small Company Fund may invest in preferred stock, securities convertible into common stock, rights and warrants. Under normal circumstances, at least 80% of the Fund's net assets (plus any borrowings for investment purposes) will be invested in stocks of companies that have market capitalizations similar in size to those companies in the Russell 2000 Growth Index. The Fund may invest up to 20% of its total assets in foreign securities, either directly or indirectly through ADRs, EDRs and CDRs. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI.

The Fund may purchase put options and call options and write covered call options as a hedge against changes resulting from market conditions and in the value of the securities held in the Fund or which it intends to purchase and where the transactions are economically appropriate for the reduction of risks inherent in the ongoing management of the Fund. See "Options on Securities" in

Part 2 of this SAI.

DIVIDEND FUND

Under normal circumstances, the Dividend Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a diversified portfolio of income-producing (dividend-paying) equity securities, which will consist primarily of common stocks but may also include preferred stocks and convertible securities. The Fund may invest up to 20% of its net assets in debt securities, including lower-quality debt securities. The Fund may invest up to 20% of its total assets in foreign securities, either directly or indirectly through ADRs, EDRs, CDRs and GDRs. See "Foreign Securities" and "American, European, Continental and Global Depositary Receipts" in Part 2 of this SAI. The Fund may also buy and sell options and futures contracts and utilize stock index futures contracts, options, swap agreements, indexed securities and options on futures contracts. See "Options on Securities" and "Futures Contracts and Related Options" in Part 2 of this SAI.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectuses under "Financial Highlights." Each Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment goal. Portfolio investments may be sold for a variety of reasons, such as a more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Funds to realize capital gains which, if realized and distributed by the Funds, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Funds.

For the Asset Allocation Fund, during the fiscal year ending September 30, 2004, the turnover decreased from 122% in the prior year to 75%. Part of the decrease was due to the restructuring of the Fund to a broadly diversified portfolio in the 2002-2003 fiscal year. We expect that prospectively turnover will generally range between 75% and 125%.

For the Growth Fund, during the fiscal year ending September 30, 2004, the Fund experienced a higher rate of portfolio turnover than during the previous fiscal year. This was due largely to volatility in individual stocks and opportunities to take advantage of inefficiently priced stocks.

For the Value Fund, during the fiscal year ending September 30, 2004, the Fund experienced a higher rate of portfolio turnover than during the previous fiscal year. This was due largely to increased opportunities in the equity market in 2004. We expect that prospectively turnover will generally range between 80% and 100%.

For the Common Stock Fund, during the fiscal year ending September 30, 2004, the Fund experienced a higher rate of portfolio turnover than during the previous fiscal year. This was due largely to change in portfolio management. We expect that prospectively turnover will generally range between 50% and 80%.

k


For the Small Company Fund, during the fiscal year ending September 30, 2004, the turnover decreased from 123% in the prior year to 54%. Part of the decrease was due to changes in portfolio managers. We expect that prospectively turnover will generally range between 90% and 120%.

For the Small Company Fund, during the fiscal year ending September 30, 2005, the turnover increased from 54% in the prior year to 110%. This increase was largely due to a change in portfolio managers. We expect that prospectively turnover will generally range between 90% and 120%.

FUND CHARGES AND EXPENSES

Effective November 1, 2004, under the Funds' management contracts, each Fund (excluding the Small Cap Core Fund and the Small Company Fund) pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of:

                        FEE    ASSET    FEE      ASSET     FEE      ASSET     FEE      ASSET     FEE      ASSET     FEE    ASSET

Under the administration agreement for each Fund (the "Agreement"), the Fund pays the Advisor a monthly fee at the annual rate of 0.067% of the average daily net assets of the Fund. The Large Cap Growth Fund pays the Advisor a monthly fee at the annual rate of 0.05% of the average daily net assets of the Fund. Prior to March 19, 2005, the Large Cap Growth Fund paid the Advisor a monthly fee at the annual rate of 0.067% of the Fund's average daily net assets. Prior to November 26, 2002, the administration agreement was computed daily and paid monthly at the annual rate of 0.09% of the first $2.5 billion of the combined average daily net assets of the Funds and the other funds offered by the Galaxy Fund, 0.085% of the next $2.5 billion of combined average daily net assets, 0.075% of the next $7 billion of combined average daily net assets, 0.065% of the next $3 billion of combined average daily net assets, 0.06% of the next $3 billion of combined average daily net assets, 0.0525% of the next $9 billion of combined average daily net assets and 0.05% of combined average daily net assets in excess of $30 billion.

The Advisor provides certain pricing and bookkeeping services to each Fund. Effective November 1, 2005, each Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Funds will continue to receive substantially the same pricing, bookkeeping and administrative services as they currently receives under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street Bank and Trust Company will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, each Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus an additional monthly fee based on each Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. Each Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement.

Under the prior pricing and bookkeeping agreement with the Funds, the Advisor received from the Funds an annual fee based on the average daily net assets of each Fund as follows: $25,000 under $50 million; $35,000 of $50 million but less than $200 million; $50,000 of $200 million but less than $500 million; $85,000 of $500 million but less than $1 billion and $125,000 in excess of $1 billion. The annual fees for a Fund with more than 25% in non-domestic assets was 150% of the annual fees described above. In addition to the above-referenced fees, each Fund paid an additional $10,000 per annum. Notwithstanding the above, for each of the Funds, the Advisor waived fees payable to it under the agreement by $500 per month.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for each Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Funds entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to each Fund (and will continue to retain Boston Financial Data Services, Inc. to assist it) for a reduced fee. The new fee is $15.23 per open account per annum, payable monthly. In addition, each Fund may pay CMS the fees and expenses it pays to third-party dealer firms that maintain omnibus accounts with the Funds, subject to a cap equal to 0.11% of each Fund's net assets represented by the account. The Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Funds and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Funds.

Prior to November 1, 2005, under the shareholders' servicing and transfer agency fee arrangement between CMS and the Funds, each Fund paid the following fees:

An annual open account fee of $28 per open account plus a Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

- A new account set up charge of $5.00 per account; plus

m

- An account maintenance fee for each open non-networked account of $14.00 per annum and for each networked account in the amount of $100,000 or less of $11.00 per annum and each networked account in the amount of over $100,000 of $8.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- An account fee for each closed account in the amount of $100,000 or less of $14.00 per annum and each closed account in the amount of over $100,000 of $11.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

COMPENSATION

As of each Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

12B-1 PLAN, SHAREHOLDER SERVICING PLAN, CDSCS AND CONVERSION OF SHARES All of the Funds offer Class A, Class B, Class C, Class G, Class T and Class Z shares. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Funds pay CMD monthly a service fee at an annual rate of 0.25% of each Fund's average daily net assets attributed to Class A, B and C shares. The Funds also pay CMD monthly a distribution fee at an annual rate of 0.10% of each Fund's average daily net assets attributed to Class A shares and 0.75% of each Fund's average daily net assets attributed to Class B and Class C shares.

For the current fiscal year, CMD intends to limit aggregate 12b-1 fees for Class A shares to 0.25%. The Funds also may pay CMD distribution and service fees up to a maximum of 1.15% of such Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% shareholder liaison services and up to 0.25% administrative support services).

For the current fiscal year, the Fund's payments under the Plan for each of distribution services, shareholder liaison services and administrative support services will be limited to 0.95% (on an annualized basis) of the average daily net asset value of Class G shares owned of record or beneficially by customers of institutions. Such limitations may be revoked at any time. CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to financial service firms ("FSFs") and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of Fund shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of the Funds' assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan ("Independent Trustees"), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class T shares of the Funds are subject to a shareholder servicing fee pursuant to a Shareholder Servicing Plan. Under the Shareholder Servicing Plan, a Fund may enter into agreements with institutions pursuant to which an institution agrees to provide certain administrative and support services to its customers who are the beneficial owners of Class T shares. Services provided by such institutions to their customers include aggregating and processing purchase and redemption requests and placing net purchase and redemption orders. In return for providing these services, the Fund agrees to pay each institution a fee at an annual rate of up to 0.50%, comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services of the average daily net assets attributable to Class T shares owned beneficially by the institution's customers. Current service arrangements are limited to payments of 0.30% for the Funds.

Under the Shareholder Servicing Plan, the Trustees must review, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which those expenditures were made. The initial term of the Shareholder Servicing Plan is one year and it will continue in effect from year to year after its initial one-year term provided that its continuance is specifically approved at least annually by a majority of the Trustees, including a majority of the Independent Trustees who have no direct or indirect financial interest in the operation of the Shareholder Servicing Plan or in any agreement related to it. Any material amendment to the

ww


Shareholder Servicing Plan must be approved in the same manner. The Shareholder Servicing Plan is terminable at any time with respect to any Fund by a vote of a majority of the Independent Trustees. While the Shareholder Servicing Plan is in effect, only the Independent Trustees may select and nominate any future Independent Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class G shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on when you purchased your shares that were exchanged for Class G shares. Class T shares are offered at net asset value plus varying sales charges which may include a CDSC. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs and initial sales charges are described in the Prospectuses.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

Eight years after the end of the month in which you purchased your shares that were exchanged for Class G shares, such Class G shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class T shares having an equal value, which are not subject to the distribution fee. See Part 2 of this Statement of Additional Information for the CDSCs and conversion schedules applicable to Class G shares received in exchange for Retail B shares purchased or acquired prior to January 1, 2001.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

2

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

3

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a

4

segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

5

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain

6

private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by

7

the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by

8

mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the

9

underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

10

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events--such as volume in excess of trading or clearing capability--were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

11

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges--principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

13

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the

14

Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

15

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

16

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

17

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

18

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking

19

into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and
(4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets. The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least M by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes

21

referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated

22

investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

23

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

24

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31 % for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to

25

generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income, possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property

26

and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1,2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS Columbia Management Advisors, LLC ("Columbia Advisors" or "CMA" or the "Advisor"), located at 100 Federal Street, Boston, Massachusetts 02110 is the Advisor to the Funds.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

Approving the Investment Advisory Contract

In determining to approve the most recent annual extension of a Fund's management agreement, the Trustees met over the course of the year with the relevant investment advisory personnel from the Advisor and considered information provided by the Advisor relating to the education, experience and number of investment professionals and other personnel providing services under that agreement. See "Managing the Fund" in each Fund's Prospectus and "Trustees and Officers" in this SAI. The Trustees also took into account the time and attention devoted by senior management to the Funds and the other funds in the Fund Complex. The Trustees evaluated the level of skill required to manage the Funds and concluded that the human resources devoted by the Advisor to the Funds were appropriate to fulfill effectively the Advisor's duties under the agreement. The Trustees also considered the business reputation of the Advisor and its financial resources, and concluded that the Advisor would be able to meet any reasonably foreseeable obligations under the agreement.

The Trustees received information concerning the investment philosophy and investment process applied by the Advisor in managing the Funds. See "Principal Investment Strategies" and "Principal Investment Risks" in the Funds' Prospectuses. In this connection, the Trustees considered the Advisor's in-house research capabilities as well as other resources available to the Advisor's personnel, including research services available to the Advisor as a result of securities transactions effected for the

34

Funds and other investment advisory clients. The Trustees concluded that the Advisor's investment process, research capabilities and philosophy were well suited to each Fund, given each Fund's investment goal(s) and policies.

The Trustees considered the scope of the services provided by the Advisor to the Funds under the agreement relative to services provided by third parties to other mutual funds. See "Fund Charges and Expenses" and "Management of the Funds--The Management Agreement". The Trustees concluded that the scope of the Advisor's services to the Funds was consistent with the Funds' operational requirements, including, in addition to its investment goal, compliance with each Fund's investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services provided by the Advisor to the Funds. The Trustees evaluated the Advisor's record with respect to regulatory compliance and compliance with the investment policies of each Fund. The Trustees also evaluated the procedures of the Advisor designed to fulfill the Advisor's fiduciary duty to the Funds with respect to possible conflicts of interest, including the Advisor's code of ethics (regulating the personal trading of its officers and employees) (see "Management of the Funds--Code of Ethics"), the procedures by which the Advisor allocates trades among its various investment advisory clients and the record of the Advisor in these matters. The Trustees also received information concerning standards of the Advisor with respect to the execution of portfolio transactions. See "Management of the Funds--Portfolio Transactions."

The Trustees considered the Advisor's management of non-advisory services provided by persons other than the Advisor by reference, among other things, to each Fund's total expenses and the reputation of each Fund's other service providers. See "Your Expenses" in each Fund's Prospectus(es). The Trustees also considered information provided by third parties relating to each Fund's investment performance relative to its performance benchmark(s), relative to other similar funds managed by the Advisor and relative to funds managed similarly by other advisors. The Trustees reviewed performance over various periods, including each Fund's one, five and ten year calendar year periods and/or the life of the Fund, as applicable (See "Performance History" in the Fund's Prospectuses), as well as factors identified by the Advisor as contributing to each Fund's performance. See each Fund's most recent annual and semi-annual reports. The Trustees concluded that the scope and quality of the Advisor's services was sufficient to merit reapproval of the agreement for another year.

In reaching that conclusion, the Trustees also gave substantial consideration to the fees payable under the agreement. The Trustees reviewed information concerning fees paid to investment advisors of similarly-managed funds. The Trustees also considered the fees of the Funds as a percentage of assets at different asset levels and possible economies of scale to the Advisor. The Trustees evaluated the Advisor's profitability with respect to the Funds, concluding that such profitability appeared to be generally consistent with levels of profitability that had been determined by courts to be "not excessive." For these purposes, the Trustees took into account not only the actual dollar amount of fees paid by the Funds directly to the Advisor, but also so-called "fallout benefits" to the Advisor such as reputational value derived from serving as investment Advisor to the Funds and the research services available to the Advisor by reason of brokerage commissions generated by each Fund's turnover. In evaluating the Funds' advisory fees, the Trustees also took into account the complexity of investment management for the Funds relative to other types of funds. Based on challenges associated with less readily available market information about foreign issuers and smaller capitalization companies, limited liquidity of certain securities, and the specialization required for focused funds, the Trustees concluded that generally greater research intensity and trading acumen is required for equity funds, and for international or global funds, as compared to funds investing, respectively, in debt obligations or in U.S. issuers. Similarly, the Trustees concluded that, generally, small capitalization equity funds and focused funds including state specific municipal funds, require greater intensity of research and trading acumen than larger capitalization or more diversified funds. See "The Fund" in each Fund's Prospectus.

Based on the foregoing, the Trustees concluded that the fees to be paid the Advisor under the advisory agreement were fair and reasonable, given the scope and quality of the services rendered by the Advisor.

Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

36

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

37

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold--for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family

38

members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

39

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http:// www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the

40

best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

41

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                            FREQUENCY OF
TYPE OF FUND                INFORMATION PROVIDED             DISCLOSURE            DATE OF WEB POSTING
------------------   ------------------------------------   ------------   ----------------------------------
Equity Funds.        Full portfolio holdings information      Monthly      30 calendar days after month-end.
Fixed Income Funds   Full portfolio holdings information.    Quarterly     60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities. Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ

42

system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund and Columbia Newport Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS.

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

43

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

44

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and

47

its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares; (ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

48

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

49

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at NAV to the following individuals, whether currently employed or retired:
Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds.

NAV eligibility for Class A purchase also applies to the families of the parties listed above and their beneficial accounts. Family members include: spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29,2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1,1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

50

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares--Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise after the purchase of shares
(ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase and (iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under
Section 501 (c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

51

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under
Section 501 (c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1 % to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

52

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. The $5,000 minimum account balance requirement has been waived for wrap accounts. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000 for non-money market funds. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1 % of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines overtime and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a

53

bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                        REALLOWANCE TO DEALERS AS   REALLOWANCE TO DEALERS AS

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1,2001:

                                        % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE           SHARES ARE SOLD
-----------------------------           ---------------

Through fifth year ..................         2 00
Through sixth year ..................         1.00
Longer than six years ...............         None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1,2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

54

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/ or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                    % DEDUCTED WHEN

Through sixth year ..............         1.00
Through the seventh year ........         None
Longer than seven years .........         None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates--(i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

55

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1 % CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A

56

shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange. Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

57

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB-rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing

59

credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1,2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

60

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

61

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

62

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated "F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected overtime by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

63

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, and D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

65

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section
IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in
Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

66

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

67

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

68

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

69

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

70

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes-Oxley Act of 2002 have been provided.

71

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

72

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

77

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

ORGANIZATION AND HISTORY
The Trust is a Massachusetts business trust organized in 1987. Each Fund is an open-end diversified management investment company representing the entire interest in a separate series of the Trust.

The Growth Stock Fund changed its name from "SteinRoe Stock Fund" to "SteinRoe Growth Stock Fund" on February 1, 1995, and from "SteinRoe Growth Stock Fund" to "Stein Roe Growth Stock Fund" on February 1, 1996, and from "Stein Roe Growth Stock Fund" to "Liberty Growth Stock Fund" on July 15, 2002, and from "Liberty Growth Stock Fund" to its current name on October 13, 2003. The Young Investor Fund changed its name from "Stein Roe Young Investor Fund" to "Liberty Young Investor Fund" on July 29, 2002, and from "Liberty Young Investor Fund" to its current name on October 13, 2003. The Trust changed its name from "SteinRoe Investment Trust" to "Stein Roe Investment Trust" on February 1, 1996, and from "Stein Roe Investment Trust" to "Liberty-Stein Roe Funds Investment Trust" on October 18, 1999, and from "Liberty-Stein Roe Funds Investment Trust" to its current name on October 13, 2003.

Prior to July 15, 2002, rather than invest in securities directly, the Funds sought to achieve their investment goals by pooling their assets with those of other investment companies for investment in another "master" mutual fund having the identical investment goals and substantially the same investment policies as its "feeder" funds.

Each Fund offers four classes of shares - Class A, B, C and Z shares. Prior to July 15, 2002, the Growth Stock Fund had a single class of shares. On that date the outstanding shares of the Fund were converted into Class Z shares, and the Fund commenced offering Class A, B and C shares. Prior to July 29, 2002, the Young Investor Fund had a single class of shares. On that date, the outstanding shares of the Fund were redesignated as Class Z shares, and the Fund commenced offering Class A, B and C shares.

It is expected that each Fund will be reorganized as a series of Columbia Funds Series Trust I, a Massachusetts business trust, into which all of the retail Columbia funds are expected to be reorganized.

Except as indicated below under "Fundamental Investment Policies," the Funds' investment policies are not fundamental and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES
The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a particular Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

c

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES
Each Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Trustees. None of the following restrictions shall prevent the Fund from investing all or substantially all of its assets in another investment company having the same investment objective and substantially the same investment policies as the Fund. Each Fund may not:

(1) Invest in any of the following: (i) interests in oil, gas, or other mineral leases or exploration or development programs (except readily marketable securities, including but not limited to master limited partnership interests, that may represent indirect interests in oil, gas, or other mineral exploration or development programs); (ii) puts, calls, straddles, spreads, or any combination thereof (except that it may enter into transactions in options, futures, and options on futures); (iii) shares of other open-end investment companies, except in connection with a merger, consolidation, acquisition, or reorganization; and (iv) limited partnerships in real estate unless they are readily marketable;

(2) Invest in companies for the purpose of exercising control or management;

(3) Purchase more than 3% of the stock of another investment company or purchase stock of other investment companies equal to more than 5% of its total assets (valued at time of purchase) in the case of any one other investment company and 10% of such assets (valued at time of purchase) in the case of all other investment companies in the aggregate; any such purchases are to be made in the open market where no profit to a sponsor or dealer results from the purchase, other than the customary broker's commission, except for securities acquired as part of a merger, consolidation or acquisition of assets;

(4) Invest more than 5% of its net assets (valued at time of purchase) in warrants, nor more than 2% of its net assets in warrants that are not listed on the New York or American Stock Exchange;

(5) Write an option on a security unless the option is issued by the Options Clearing Corporation, an exchange, or similar entity;

(6)(a) Growth Stock Fund ONLY may not invest more than 25% of its total assets (valued at time of purchase) in securities of foreign issuers (other than securities represented by American Depositary Receipts ("ADRs") or securities guaranteed by a U.S. person);

(6)(b) Young Investor Fund ONLY may not invest more than 33% of its total assets (valued at time of purchase) in securities of foreign issuers (other than securities guaranteed by a U.S. person);

d

(7) Purchase a put or call option if the aggregate premiums paid for all put and call options exceed 20% of its net assets (less the amount by which any such positions are in-the-money), excluding put and call options purchased as closing transactions;

(8) Purchase securities on margin (except for use of short-term credits as are necessary for the clearance of transactions), or sell securities short unless (i) it owns or has the right to obtain securities equivalent in kind and amount to those sold short at no added cost or (ii) the securities sold are "when issued" or "when distributed" securities which it expects to receive in a recapitalization, reorganization, or other exchange for securities it contemporaneously owns or has the right to obtain and provided that transactions in options, futures, and options on futures are not treated as short sales;

(9) Invest more than 5% of its total assets (taken at market value at the time of a particular investment) in restricted securities, other than securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933; or

(10) Invest more than 15% of its net assets (taken at market value at the time of a particular investment) in illiquid securities, including repurchase agreements maturing in more than seven days.

(Growth Stock Fund ONLY may not): acquire securities of other registered open-end investment companies or registered unit investment trusts in reliance on section 12(d)(1)(F) or (G) of the 1940 Act.

PORTFOLIO TURNOVER
Although neither Fund purchases securities with a view to rapid turnover, there are no limitations on the length of time that portfolio securities must be held. Portfolio turnover can occur for a number of reasons such as general conditions in the securities markets, more favorable investment opportunities in other securities, or other factors relating to the desirability of holding or changing a portfolio investment. Because of each Fund's flexibility of investment and emphasis on growth of capital, it may have greater portfolio turnover than that of mutual funds that have primary objectives of income or maintenance of a balanced investment position. The future turnover rate may vary greatly from year to year. A high rate of portfolio turnover in a Fund, if it should occur, would result in increased transaction expenses, which must be borne by the Fund. High portfolio turnover may also result in the realization of capital gains or losses and, to the extent net short-term capital gains are realized, any distributions resulting from such gains will be considered ordinary income for federal income tax purposes.

FUND CHARGES AND EXPENSES
Under the Growth Stock Fund's Management Agreement, the Fund pays the Advisor a monthly fee based on average net assets, determined at the close of each business day during the month, at the annual rate of 0.600% up to $500 million; 0.550% of the next $500 million; 0.500% of the next $1 billion; and 0.450% thereafter. The Fund pays the Advisor a monthly Administrative Fee based on average daily net assets at the close of each business day during the month at the rate of 0.150% up to $500 million; 0.125% of the next $500 million; 0.100% on the next $500 million, 0.075% on the next $500 million and 0.050% thereafter.

Under the Young Investor Fund's Management Agreement, the Fund pays the Advisor a monthly fee based on average net assets, determined at the close of each business day during the month, at the annual rate of 0.600% up to $500 million, 0.550% of the next $500 million, and 0.500% over $1 billion. The Fund pays the Advisor a monthly Administrative Fee based on average daily net assets at the close of each business day during the month at the rate of 0.200% up to $500 million, 0.150% of the next $500 million, and 0.125% over $1 billion.

The Advisor provides certain pricing and bookkeeping services to each Fund. Effective November 1, 2005, each Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Funds will continue to receive substantially the same pricing, bookkeeping and administrative services as they currently receive under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, each Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus an additional monthly fee based on each Fund's net asset value ("Fund Accounting Fee"); and

e


(ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. Each Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement.

For periods prior to November 1, 2005, each Fund paid the Advisor fees under a similar pricing and bookkeeping agreement that consisted of a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

- An annual flat fee of $10,000, paid monthly; and
- In any month that a Fund had average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

The Fund reimbursed the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Funds. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Funds entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to the Funds (and will continue to retain Boston Financial Data Services, Inc. to assist them) for a reduced fee. The new fee is $15.23 per open account per annum, payable monthly. In addition, the Funds may pay CMS the fees and expenses they pay to third-party dealer firms that maintain omnibus accounts with the Funds, subject to a cap equal to 0.11% of each Fund's net assets represented by the account. The Funds will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Funds and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Funds.

Effective November 1, 2004, the Advisor has voluntarily agreed to reimburse the Young Investor Fund for certain expenses so that the transfer agency fees for each of Class A, B, C and Z shares will not exceed 0.10%. This arrangement may be modified or terminated by the Advisor at any time.

Prior to November 1, 2005, the Funds paid a shareholders' servicing and transfer agency fee to CMS as follows:

An annual open account fee of $28 per open account, plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

Prior to November 1, 2003, the Funds paid a shareholders' servicing and transfer agency fee to CMS as follows:

Each Fund's agreement was such that the fees for Classes A, B and C were aggregated, and the fees for Class Z were applied individually as follows:

- An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
- An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
- A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus
- A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of the Fund for such month; plus
- The Fund's allocated share of CMS' out-of-pocket expenses, including fees payable to DST Systems, Inc. ("DST") under a remote services agreement with DST.

COMPENSATION

As of the Funds' most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES
Each Fund offers four classes of shares -- Class A, Class B, Class C and Class Z. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act for the Funds' Class A, B and C shares. Under the Plan, the Funds pay CMD monthly a service fee at an annual rate of 0.25% of each Fund's net assets attributed to Class A, B and C shares. The Funds also pay CMD monthly a distribution fee at an annual rate of 0.10% of each Fund's average daily net assets attributed to Class A shares and 0.75% of each Fund's average daily net assets attributed to Class B and C shares. At this time, CMD has voluntarily agreed to waive a portion of the Class A share distribution fee so that it does not exceed 0.05% annually. This arrangement may be modified or terminated by CMD at any time. CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to financial service firms ("FSFs") and for certain other purposes. Since the distribution and service fees are payable regardless of CMD's expenses, CMD may realize a profit from the

n


fees. The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of each Fund's shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in a more advantageous expense ratio and increased investment flexibility which could benefit each class of each Fund's shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan ("Independent Trustees"), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares, and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within six years after purchase. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs and initial sales charges are described in the Prospectuses relating to Class A, B and C shares.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions, and finally of other shares held by the shareholder for the longest time.

Eight years after the end of the month in which a Class B share is purchased, such shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

7. The section entitled "Trustee Positions," a subsection of "Management of the Funds," is revised to read:

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Columbia Fund Complex or any person controlling, controlled by or under common control with any such entity.

"CMD"                         Columbia Management Distributors, Inc. (formerly named
                              Columbia Funds Distributor, Inc.), the Fund's distributor

                              transfer agent

ORGANIZATION AND HISTORY
The Trust is a Massachusetts business trust organized in 1986. The Fund is an open-end diversified management investment company, representing the entire interest in a separate series of the Trust. The Liberty Fund commenced investment operations on April 30, 1982, and is a successor to a corporation organized in 1904.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of the Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

Effective July 14, 2000, the Liberty Fund changed its name from "The Colonial Fund" to "The Liberty Fund". Effective October 13, 2003, the Liberty Fund changed its name from "The Liberty Fund" to its current name.

Effective April 1, 1999, the Trust changed its name from "Colonial Trust III" to "Liberty Funds Trust III". Effective October 13, 2003, the Trust changed its name from "Liberty Funds Trust III" to its current name.

It is expected that, subject to shareholder approval of the election of all current Trustees, the Fund will be reorganized as a series of Columbia Funds Series Trust I, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

Except as indicated below under "Fundamental Investment Policies," the Fund's investment policies are not fundamental and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES
The Investment Company Act of 1940, as amended (the "1940 Act"), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

FUNDAMENTAL RESTRICTIONS
The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act"), except when it might be deemed to be an underwriter either:
(a) in connection with the disposition of a portfolio security; or
(b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) the Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

c

OTHER INVESTMENT POLICIES
As non-fundamental investment policies, which may be changed without a shareholder vote, the Fund may not:

1. Purchase securities on margin, but it may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;
2. Have a short securities position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and
3. Invest more than 15% of its net assets in illiquid assets.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

PORTFOLIO TURNOVER
Portfolio turnover is included in the Prospectuses under "Financial Highlights." High portfolio turnover may cause the Fund to realize capital gains which, if realized and distributed by the Fund, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Fund.

FUND CHARGES AND EXPENSES
Effective November 1, 2003, under the Liberty Fund's management agreement, the Fund pays the Advisor a monthly fee at the annual rate of 0.55% of the first $1 billion of the average daily net assets of the Fund, 0.50% of the next $500 million and 0.45% of average daily net assets in excess of $1.5 billion. Prior to November 1, 2003, under the Liberty Fund's management agreement, the Fund paid the Advisor a monthly fee at the annual rate of 0.55% of the first $1 billion of the average daily net assets of the Fund and 0.50% of the average daily net assets in excess of $1 billion.

The Advisor is responsible for providing certain pricing and bookkeeping services to the Fund. Effective November 1, 2005, the Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Fund will continue to receive substantially the same pricing, bookkeeping and administrative services as it currently receives under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street Bank and Trust Company will continue to provide these services to the Fund. For services provided under the Pricing and Bookkeeping Agreement, the Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus an additional monthly fee based on the Fund's net asset value ("Fund Accounting Fee"); and
(ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. For services provided under the Administrative Agreement, the Fund will pay the Advisor an annual fee equal to $0. The Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

For periods prior to November 1, 2005, the Fund paid the Advisor fees under a similar pricing and bookkeeping agreement that consisted of monthly fees consisting of a flat fee plus an asset-based fee, as follows:

- An annual flat fee of $10,000, paid monthly; and
- In any month that the Fund had average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that was calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

Effective November 1, 2003 the Fund reimbursed the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Fund has entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and

d

shareholders' servicing agency services to the Fund (and will continue to retain Boston Financial Data Services, Inc. to assist them) for a reduced fee. The new fee is $15.23 per open account per annum, payable monthly. In addition, the Fund may pay CMS the fees and expenses it pays to third-party dealer firms that maintain omnibus accounts with the Fund, subject to a cap equal to 0.11% of the Fund's net assets represented by the account. The Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Fund.

Prior to November 1, 2005, the Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

An annual open account fee of $28 per open account plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

Prior to November 1, 2003, the Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

- An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
- An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
- A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus
- A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of the Fund for such month; plus
- The Fund's allocated share of CMS' out-of-pocket expenses, including fees payable to DST Systems, Inc. (DST) under a remote services agreement with DST.

COMPENSATION
As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

(a) The Fund changed its fiscal year end from October 31 to September 30 in 2003.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES
The Fund offers four classes of shares -- Class A, Class B, Class C and Class Z. The Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for Class A, Class B and Class C shares. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.15% of the Fund's net assets attributable to Class A shares outstanding prior to April 1, 1989, and a service fee at an annual rate of 0.25% of the Fund's net assets attributable to shares of each Class issued thereafter, except Class Z shares. The Fund also pays CMD monthly a distribution fee at an annual rate of 0.75% of the average daily net assets attributable to its Class B and Class C shares. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Fund to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirectly financing the distribution of Fund shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of the Fund's assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Fund and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses for the Fund's Class A, B and C shares.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years after the end of the month in which a Class B share is purchased, such shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1986. Each Fund is an open-end, management investment company representing the entire interest in a separate series of the Trust. Each Fund is a non-diversified series of the Trust. Each Fund is the successor to a separate series of The Galaxy Fund, a Massachusetts business trust organized on March 31, 1986. On November 18, 2002, November 25, 2002, and December 9, 2002, the series of The Galaxy Fund to which the Funds succeeded (the "Predecessor Funds") were reorganized as separate series of the Trust. Class T shares of the Funds were issued in exchange for Retail A Shares of the Predecessor Funds, Class G shares of the Funds were issued in exchange for Retail B Shares of the Predecessor Funds and Class Z shares of the Funds were issued in exchange for Trust Shares of the Predecessor Funds.

The New Jersey Fund commenced operations on April 3, 1998; the New York Fund commenced operations on December 31, 1991; and the Rhode Island Fund commenced operations on December 20, 1994.

The Connecticut Fund and Massachusetts Fund commenced operations as separate portfolios (each a "Predecessor Boston 1784 Fund," and collectively, the "Predecessor Boston 1784 Funds") of the Boston 1784 Funds. On June 26, 2000, each Predecessor Boston 1784 Fund was reorganized as a new portfolio of The Galaxy Fund (the "Boston 1784 Reorganization"). Prior to the Boston 1784 Reorganization, the Predecessor Boston 1784 Funds offered and sold one class of shares. In connection with the Boston 1784 Reorganization, shareholders of the Predecessor Boston 1784 Funds exchanged their shares for Shares, Trust Shares and/or BKB Shares of the Predecessor Funds to the Connecticut Fund and Massachusetts Fund, respectively. Shareholders of the Predecessor Boston 1784 Funds who purchased their shares through an investment management, trust, custody, or other agency relationship with BankBoston, N.A. received Shares or Trust Shares of the Funds. BKB Shares were issued to shareholders of the Predecessor Boston 1784 Funds who were not eligible to receive Trust Shares at the time of the Boston 1784 Reorganization. On June 26, 2001, BKB Shares of the Funds converted into Retail A Shares upon a finding by the Board of Trustees of The Galaxy Fund at a meeting held on May 31, 2001, that such conversion was in the best interest of the holders of BKB Shares.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of the Funds and any other series of the Trust that may be in

b


existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

The Funds offer six classes of shares -- A, B, C, G, T and Z shares.

Effective April 1, 1999, the Trust changed its name from Colonial Trust V to Liberty Funds Trust V. Effective October 13, 2003, the Trust changed its name from Liberty Funds Trust V to its current name. On October 13, 2003, each of the Funds changed their names as follows:

Former Name:                                             Current Name:
------------                                             -------------

LIBERTY NEW YORK INTERMEDIATE MUNICIPAL BOND FUND        COLUMBIA NEW YORK INTERMEDIATE MUNICIPAL BOND FUND
LIBERTY RHODE ISLAND INTERMEDIATE MUNICIPAL BOND FUND    COLUMBIA RHODE ISLAND INTERMEDIATE MUNICIPAL BOND FUND

It is expected that, subject to shareholder approval of the election of all current Trustees, each Fund will be reorganized as a series of Columbia Funds Series Trust I, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

In addition to each Fund's investment goal as stated in its Prospectuses, the following investment limitations are matters of fundamental policy and may not be changed with respect to a Fund without the affirmative vote of the holders of a majority of its outstanding shares. A "vote of the holders of a majority of the outstanding shares" of a particular Fund means the affirmative vote of the holders of the lesser of (a) more than 50% of the outstanding shares of such Fund, or (b) 67% or more of the shares of such Fund present at a meeting if more than 50% of the outstanding shares of such Fund are represented at the meeting in person or by proxy.

CONNECTICUT FUND

As a matter of fundamental policy that cannot be changed without the requisite consent of the Fund's shareholders, the Connecticut Fund will invest, except during temporary defensive periods, at least 80% of its net assets (plus any borrowings for investment purposes) in Municipal Securities issued by or on behalf of the State of Connecticut, its political sub-divisions, or any public instrumentality, state or local authority, district or similar public entity created under the laws of Connecticut and certain other governmental issuers (which may include issuers located outside Connecticut such as Puerto Rico), the interest on which is, in the opinion of qualified legal counsel, exempt from regular federal income tax (including the federal alternative minimum tax) and from Connecticut personal income tax by virtue of federal law ("Connecticut Municipal Securities"). The Fund may comply with this 80% policy by investing in a partnership, trust or other entity which invests in such Connecticut Municipal Securities, in which case the Fund's investment in such entity shall be deemed to be an investment in the underlying Connecticut Municipal Securities in the same proportion as such entity's investment in such Connecticut Municipal Securities bears to its net assets. Dividends derived from interest on Municipal Securities other than Connecticut Municipal Securities will generally be exempt from regular federal income tax (including the federal alternative minimum tax) but subject to Connecticut personal income tax. See Part 2 of this SAI under the caption, "Taxes".

MASSACHUSETTS FUND

As a matter of fundamental policy that cannot be changed without the requisite consent of the Fund's shareholders, the Massachusetts Fund will invest, except during temporary defensive periods, at least 80% of its net assets (plus any borrowings for investment purposes) in Municipal Securities, issued by or on behalf of the Commonwealth of Massachusetts, its political sub-divisions, authorities, agencies, instrumentalities and corporations, and certain other governmental issuers (which may include issuers located outside Massachusetts such as Puerto Rico), the interest on which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax (including the federal alternative minimum tax) and Massachusetts personal income tax ("Massachusetts Municipal Securities"). The Fund may comply with this 80% policy by investing in a partnership, trust, regulated investment company or other entity which invests in such Massachusetts Municipal Securities, in which case the Fund's investment in such entity shall be deemed to be an investment in the underlying Massachusetts Municipal Securities in the same proportion as such entity's investment in such Massachusetts Municipal Securities bears to its net assets. Dividends derived from interest on Municipal Securities other than Massachusetts Municipal Securities will generally be exempt from regular federal income tax (including the federal alternative minimum tax) but may be subject to Massachusetts personal income tax. See Part 2 of this SAI under the caption, "Taxes".

NEW JERSEY FUND

Dividends derived from interest on Municipal

d

Securities other than New Jersey Municipal Securities will generally be exempt from regular federal income tax but may be subject to New Jersey personal income tax (including the federal alternative minimum tax). See Part 2 of this SAI under the caption, "Taxes".

NEW YORK FUND

As a matter of fundamental policy that cannot be changed without the requisite consent of the Fund's shareholders, the New York Fund will invest, except during temporary defensive periods, at least 80% of its net assets (plus any borrowings for investment purposes) in Municipal Securities issued by or on behalf of the State of New York, its political sub-divisions, authorities, agencies, instrumentalities and corporations, and certain other governmental issuers (which may include issuers located outside New York such as Puerto Rico), the interest on which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax (including the federal alternative minimum tax) and New York State and New York City personal income tax ("New York Municipal Securities"). Dividends derived from interest on Municipal Securities other than New York Municipal Securities will generally be exempt from regular federal income tax (including the federal alternative minimum tax) but may be subject to New York State and New York City personal income tax. See Part 2 of this SAI under the caption, "Taxes".

RHODE ISLAND FUND

As a matter of fundamental policy that cannot be changed without the requisite consent of the Fund's shareholders, the Rhode Island Fund will invest, except during temporary defensive periods, at least 80% of its net assets (plus any borrowings for investment purposes) in Municipal Securities issued by or on behalf of the State of Rhode Island, its political sub-divisions, authorities, agencies, instrumentalities and corporations, and certain other governmental issuers (which may include issuers located outside Rhode Island such as Puerto Rico), the interest on which, in the opinion of bond counsel to the issuer, is exempt from regular federal income taxes (including the federal alternative minimum tax) and Rhode Island personal income taxes ("Rhode Island Municipal Securities"). Dividends derived from interest on Municipal Securities other than Rhode Island Municipal Securities will generally be exempt from regular federal income tax (including the federal alternative minimum tax) but may be subject to Rhode Island personal income tax. See Part 2 of this SAI under the caption, "Taxes".

ADDITIONAL FUNDAMENTAL INVESTMENT POLICIES

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by Investment Company Act of 1940 (the "1940 Act"), the rules and regulations thereunder and any applicable exemptive relief.

e


5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

NON-FUNDAMENTAL INVESTMENT POLICIES

The following investment limitations with respect to the CONNECTICUT FUND, MASSACHUSETTS FUND, NEW JERSEY FUND, NEW YORK FUND and RHODE ISLAND FUND may be changed by the Trust's Board of Trustees without shareholder approval:

1. A Fund may not sell securities short, maintain a short position, or purchase securities on margin, except for such short-term credits as are necessary for the clearance of transactions.

2. A Fund may not write or sell put options, call options, straddles, spreads or any combination thereof, except that a Fund may, to the extent consistent with its investment goal and policies, write covered call options and purchase and sell other options.

3. A Fund may not purchase securities of companies for the purpose of exercising control.

4. A Fund may not purchase the securities of other investment companies except as permitted by the 1940 Act.

The following investment limitations with respect to the NEW JERSEY FUND, NEW YORK FUND and RHODE ISLAND FUND may be changed by the Trust's Board of Trustees without shareholder approval:

1. Each of the New Jersey Fund, New York Fund and Rhode Island Fund may not purchase securities of any one issuer, other than obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities, if immediately after such purchase more than 5% of the value of the Fund's total assets would be invested in the securities of such issuer, except that up to 50% of the value of the Fund's total assets may be invested without regard to this 5% limitation, provided that no more than 25% of the value of the Fund's total assets are invested in the securities of any one issuer. A Fund may not invest more than 15% of its net assets in illiquid securities.

2. Each Fund may invest in foreign securities to the extent consistent with its investment goal and policies.

The following investment limitations with respect to the CONNECTICUT FUND and MASSACHUSETTS FUND may be changed by the Trust's Board of Trustees without shareholder approval:

1. No Fund may invest in warrants.

2. No Fund may invest in illiquid securities in an amount exceeding, in the aggregate, 15% of that Fund's net assets.

3. No Fund may purchase or retain securities of an issuer if, to the knowledge of the Trust, an officer, trustee, member or director of the Trust or any investment adviser of the Trust owns beneficially more than 1/2 of 1% of the shares or securities of such issuer and all such officers, trustees, members and directors owning more than 1/2 of 1% of such shares or securities together own more than 5% of such shares or securities.

4. No Fund may invest in interests in oil, gas or other mineral exploration or development programs. No Fund may invest in oil, gas or mineral leases.

Municipal Securities purchased by the Funds will consist primarily of issues which are rated at the time of purchase within the four highest rating categories assigned by S&P or Moody's or unrated instruments determined by the advisor to be of comparable quality. Municipal Securities rated within the four highest rating categories assigned by S&P (AAA, AA, A and BBB) or Moody's (Aaa, Aa, A and Baa) are considered to be investment grade. Municipal Securities rated in the lowest of the four highest rating categories assigned by S&P or Moody's are considered to have speculative characteristics, even though they are of investment grade quality, and changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case with higher grade Municipal Securities. Such Municipal Securities will be purchased (and retained) only when the Advisor believes the issuers have an adequate capacity to pay interest and repay principal. If the ratings of a particular Municipal Security purchased by a Fund are subsequently downgraded below the four highest ratings categories assigned by S&P or Moody's, such factor will be considered by the Advisor in its evaluation of the overall merits of that

f


Municipal Security, but such ratings will not necessarily result in an automatic sale of the Municipal Security unless the Municipal Security, together with any other securities held by the Fund that are rated below investment grade, exceed 5% of the Fund's net assets. Under normal market and economic conditions, at least 65% of each Fund's total assets will be invested in Municipal Securities rated in the three highest rating categories assigned by S&P or Moody's. See Appendix I to Part 2 of this Statement of Additional Information for a description of S&P's and Moody's rating categories.

Although no Fund presently intends to do so on a regular basis, each Fund may invest more than 25% of its assets in Municipal Securities the interest on which is paid solely from revenues on similar projects if such investment is deemed necessary or appropriate by the Advisor. To the extent that a Fund's assets are concentrated in Municipal Securities payable from revenues on similar projects, the Fund will be subject to the particular risks presented by such projects to a greater extent than it would be if its assets were not so concentrated.

Among other instruments, the Funds may purchase short-term general obligation notes, tax anticipation notes, bond anticipation notes, revenue anticipation notes, commercial paper, construction loan notes and other forms of short-term loans that are rated in the two highest rating categories assigned by a rating agency with respect to such instruments or, if unrated, determined by the advisor to be of comparable quality. Such instruments are issued with a short-term maturity in anticipation of the receipt of tax funds, the proceeds of bond placements or other revenues. In addition, the Funds may invest in long-term tax-exempt instruments, such as municipal bonds and private activity bonds to the extent consistent with the limitations set forth in the Prospectuses.

Investments in private activity bonds will not be treated as investments in Municipal Securities for purposes of the 80% requirement mentioned above and, under normal conditions, will not exceed 20% of a Fund's total assets when added together with any taxable investments held by the Fund.

The Funds currently intend to limit the lending of their portfolio securities so that, at any given time, securities loaned by a Fund represent not more than one-third of the value of its total assets.

Each Fund may purchase restricted securities, which are any securities in which the Fund may otherwise invest pursuant to its investment goal and policies but which are subject to restrictions on resale under the federal securities laws. Certain restricted securities may be considered liquid pursuant to guidelines established by the Board of Trustees. To the extent restricted securities are deemed illiquid, each Fund will limit its purchase, together with other securities considered to be illiquid, to 15% of its net assets.

Each Fund currently expects that forward commitments, when-issued purchases and delayed settlements will not exceed 25% of the value of a Fund's total assets absent unusual market conditions. In the event a Fund's forward commitments, when-issued purchases and delayed settlements ever exceeded 25% of the value of its total assets, the Fund's liquidity and the ability of the Advisor to manage the Fund might be adversely affected. The Funds do not intend to engage in when-issued purchases, forward commitments and delayed settlements for speculative purposes, but only in furtherance of their investment goals.

A Fund will not invest more than 10% of its total assets in asset-backed securities.

Each of the Connecticut Fund and Massachusetts Fund may also invest in mortgage-backed securities not issued by governmental issuers which are rated in one of the top three rating categories by S&P, Moody's or Fitch Ratings, or if unrated, determined by the Advisor to be of comparable quality.

Each Fund will only enter into repurchase agreements with financial institutions such as banks and broker/dealers which are deemed to be creditworthy by the Advisor. None of the Funds will enter into repurchase agreements with the Advisor or any of its affiliates. Investments by the Funds in repurchase agreements will be, under normal market conditions, subject to such Fund's 20% overall limit on taxable obligations.

Each of the Connecticut Fund and Massachusetts Fund may write covered call options provided that the aggregate value of such options does not exceed 10% of such Fund's net assets as of the time such Fund enters into such options. These Funds may write covered call options for hedging purposes only and will not engage in option writing strategies for speculative purposes.

g


Each of the New Jersey Fund, New York Fund and Rhode Island Fund may purchase and sell municipal bond index futures contracts as a hedge against changes in market conditions. Each of these Funds may also enter into contracts for the future delivery of fixed income securities commonly known as interest rate futures contracts. These Funds will not engage in futures transactions for speculation, but only to hedge against changes in the market values of securities which the Funds hold or intend to purchase. Each of these Funds will limit its hedging transactions in futures contracts so that, immediately after any such transaction, the aggregate initial margin that is required to be posted by the Fund under the rules of the exchange on which the futures contract is traded does not exceed 5% of the Fund's total assets after taking into account any unrealized profits and unrealized losses on the Fund's open contracts. In addition, no more than one-third of each of these Fund's total assets may be covered by such contracts.

The New Jersey Fund, New York Fund and Rhode Island Fund may invest in securities issued by other investment companies which invest in high quality, short-term debt securities and which determine their net asset value per share based on the amortized cost or penny-rounding method.

Because the Connecticut Fund and Massachusetts Fund may buy and sell securities denominated in currencies other than the U.S. dollar, these Funds from time to time may enter into foreign currency exchange transactions to convert the U.S. dollar to foreign currencies, to convert foreign currencies to the U.S. dollar and to convert foreign currencies to other foreign currencies. These Funds also may engage in currency swaps.

The Connecticut Fund and Massachusetts Fund may invest in securities issued by other investment companies and foreign investment trusts. Each of these Funds may also invest up to 5% of its total assets in closed-end investment companies that primarily hold securities of non-U.S. issuers.

Except as stated otherwise, if a percentage limitation is satisfied at the time of investment, a later increase in such percentage resulting from a change in the value of a Fund's portfolio securities generally will not constitute a violation of the limitation. If the value of a Fund's holdings of illiquid securities at any time exceeds the percentage limitation applicable at the time of acquisition due to subsequent fluctuations in value or other reasons, the Board of Trustees will consider what actions, if any, are appropriate to maintain adequate liquidity. With respect to borrowings, if a Fund's asset coverage at any time falls below that required by the 1940 Act, the Fund will reduce the amount of its borrowings in the manner required by the 1940 Act to the extent necessary to satisfy the asset coverage requirement.

Each Fund may follow non-fundamental operating policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectuses and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act.

CONNECTICUT TAX CONSIDERATIONS

Dividends paid by the Connecticut Fund that qualify as exempt-interest dividends for federal income tax purposes are not subject to the Connecticut personal income tax imposed on resident and non-resident individuals, trusts and estates to the extent that they are derived from Connecticut Municipal Securities (as defined above). Other Fund dividends and distributions, whether received in cash or additional shares, may be subject to this tax, except that, in the case of shareholders who hold their shares of the Fund as capital assets, distributions treated as capital gain dividends for federal income tax purposes are not subject to the tax to the extent that they are derived from obligations issued by or on behalf of the State of Connecticut, its political subdivisions, or any public instrumentality, state or local authority, district or similar public entity created under the laws of Connecticut. Dividends and distributions paid by the Fund that constitute items of tax preference for purposes of the federal alternative minimum tax, other than any derived from Connecticut Municipal Securities, could cause liability for the net Connecticut minimum tax applicable to investors subject to the Connecticut personal income tax who are required to pay the federal alternative minimum tax. Dividends paid by the Fund, including those that qualify as exempt-interest dividends for federal income tax purposes, are taxable for purposes of the Connecticut Corporation Business Tax; however, 70% of amounts that are treated as dividends and not as exempt-interest dividends or capital gain dividends for federal income tax purposes are deductible for purposes of this tax, but no deduction is allowed for expenses related thereto. Shares of the Fund are not subject to property taxation by Connecticut or its political subdivisions.

The foregoing is a general summary of the Connecticut tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

h


MASSACHUSETTS TAX CONSIDERATIONS

Distributions by the Massachusetts Fund to its shareholders are exempt from Massachusetts personal income taxation to the extent they are derived from (and designated by the Fund as being derived from) (i) interest on Massachusetts Municipal Securities (as defined above), (ii) capital gains realized by the Fund from the sale of certain Massachusetts Municipal Securities, or (iii) interest on U.S. Government obligations exempt from state income taxation. Distributions from a Fund's other net investment income and short-term capital gains will be taxable as ordinary income. Distributions from a Fund's net long-term capital gains will be taxable as long-term capital gains regardless of how long the shareholder has owned Fund shares. The tax treatment of distributions is the same whether distributions are paid in cash or in additional shares of the Fund. Shareholders should consult their tax advisers with respect to the Massachusetts tax treatment of capital gain distributions from each Fund.

Distributions by the Massachusetts Fund to corporate shareholders, including exempt-interest dividends, may be subject to Massachusetts corporate excise tax. Fund shares are not, however, subject to property taxation by Massachusetts or its political subdivisions.

The foregoing is a general summary of the Massachusetts tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

NEW JERSEY TAX CONSIDERATIONS

It is anticipated that substantially all dividends paid by the New Jersey Fund will not be subject to New Jersey personal income tax. In accordance with the provisions of New Jersey law as currently in effect, distributions paid by a "qualified investment fund" will not be subject to the New Jersey personal income tax to the extent that the distributions are attributable to income received as interest or gain from New Jersey Municipal Securities (as defined above), or as interest or gain from direct U.S. Government obligations. Distributions by a "qualified investment fund" that are attributable to most other sources will be subject to the New Jersey personal income tax. Shares of the Fund are not subject to property taxation by New Jersey or its political subdivisions. The New Jersey personal income tax is not applicable to corporations. For all corporations subject to the New Jersey Corporation Business Tax, dividends and distributions from a "qualified investment fund" are included in the net income tax base for purposes of computing the Corporation Business Tax. Furthermore, any gain upon the redemption or sale of shares by a corporate shareholder is also included in the net income tax base for purposes of computing the Corporation Business Tax. The foregoing is a general summary of the New York tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

NEW YORK TAX CONSIDERATIONS

With respect to the New York Fund, exempt-interest dividends (as defined for federal income tax purposes), derived from interest on New York Municipal Securities (as defined above) will be exempt from New York State and New York City personal income taxes (but not corporate franchise taxes), provided the interest on such obligations is and continues to be exempt from applicable federal income taxes and New York State and New York City personal income taxes. To the extent that investors are subject to state and local taxes outside of New York State and New York City, dividends paid by the Fund will generally be taxable income for purposes thereof. Dividends and distributions derived from income (including capital gains on all New York Municipal Securities) other than interest on New York Municipal Securities described above are not exempt from New York State and New York City taxes. Interest or indebtedness incurred or continued by a shareholder to purchase or carry shares of the Fund is not deductible for federal income tax purposes or for New York State or New York City personal income tax purposes.

The foregoing is a general summary of the New Jersey tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

RHODE ISLAND TAX CONSIDERATIONS

The Rhode Island Fund has received a ruling from the Rhode Island Division of Taxation to the effect that distributions by it to its shareholders are exempt from Rhode Island personal income taxation and the Rhode Island business corporation tax to the extent they are derived from (and designated by the Fund as being derived from) interest earned on Rhode Island Municipal Securities (as defined above) or obligations of the United States. Distributions from the Fund's other net investment income and short-term capital gains will be taxable as ordinary income. Distributions from

i

the Fund's net long-term capital gains will be taxable as long-term capital gains regardless of how long the shareholder has owned Fund shares. The tax treatment of distributions is the same whether distributions are paid in cash or in additional shares of the Fund.

The Rhode Island Fund will be subject to the Rhode Island business corporation tax on its "gross income" apportioned to the State of Rhode Island. For this purpose, gross income does not include interest income earned by the Fund on Rhode Island Municipal Securities and obligations of the United States, capital gains realized by the Fund on the sale of certain Rhode Island Municipal Securities, and 50 percent of the Fund's other net capital gains.

The foregoing is a general summary of the Rhode Island tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectuses under "Financial Highlights." Each Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment goal. Portfolio investments may be sold for a variety of reasons, such as a more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Funds to realize capital gains which, if realized and distributed by the Funds, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Funds.

FUND CHARGES AND EXPENSES

Effective February 9, 2005, under the Funds' management agreement with the Advisor, each Fund pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of:

Average Daily Net Assets                               Rate
------------------------                              -----
Net assets under $500 million                         0.480%
Net assets of $500 million but less than $1 billion   0.430%
Net assets of $1 billion but less than $1.5 billion   0.400%
Net assets of $1.5 billion but less than $3 billion   0.370%
Net assets of $3 billion but less than $6 billion     0.360%
Net assets in excess of $6 billion                    0.350%

Prior to November 1, 2003, the Advisor was entitled to receive advisory fees, computed daily and paid monthly, at the annual rate of 0.75% of the average daily net assets of each Fund. In addition, the Advisor waived fees as follows:
0.20% of the first $500 million of average daily net assets, plus 0.25% of the next $500 million of average daily net assets, plus 0.30% of the next $500 million of average daily net assets, plus 0.35% of the next $500 million of average daily net assets, plus 0.40% of average daily net assets in excess of $2 billion.

Effective November 1, 2003, the Board of Trustees approved a new management fee structure for the Funds as follows: 0.55% of the first $500 million of average daily net assets, plus 0.50% of the next $500 million of average daily net assets, plus 0.45% of the next $500 million of average daily net assets, plus 0.40% of the next $500 million of average daily net assets, plus 0.35% of average daily net assets in excess of $2 billion.

Under each Fund's administration agreement (the "Agreement"), the Fund pays the Advisor a monthly fee at the annual rate of 0.067% of the average daily net assets of the Fund. Prior to November 15, 2002, the administration agreement was computed daily and paid monthly at the annual rate of 0.09% of the first $2.5 billion of the combined average daily net assets of the Funds and the other funds offered by Galaxy, 0.085% of the next $2.5 billion of combined average daily net assets, 0.075% of the next $7 billion of combined average daily net assets, 0.065% of the next $3 billion of combined average daily net assets, 0.06% of the next $3 billion of combined average daily net assets, 0.0575% of the next $3 billion of combined average daily net assets, 0.0525% of the next $9 billion of combined average daily net assets, and 0.05% of combined average daily net assets in excess of $30 billion.

j


The Advisor provides certain pricing and bookkeeping services to the Funds. Effective November 1, 2005, the Funds entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Funds will continue to receive substantially the same pricing, bookkeeping and administrative services as they currently receive under the Agreement. The Advisor and State Street Bank and Trust Company ("State Street") will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, the Funds will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus an additional monthly fee based on the Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. The Funds will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

ROLE OF THE BOARD OF TRUSTEES

The Trustees of the Funds are responsible for the overall management and supervision of the Funds' affairs and for protecting the interests of the shareholders.

The Trustees have created several committees to perform specific functions for the Funds.

The Audit Committee's functions include making recommendations to the Trustees regarding the selection and performance of the independent auditors, and reviewing matters relative to accounting and auditing practices and procedures, accounting records, and the internal accounting controls of the Funds and certain service providers. For the fiscal year ended October 31, 2005, the Audit Committee convened seven times.

GOVERNANCE COMMITTEE

Messrs. Lowry, Mayer, Simpson and Theobald are members of the Governance Committee of the Board of Trustees of the Funds. The Governance Committee's functions include recommending to the Trustees nominees for independent Trustee positions and for appointments to various committees, performing periodic evaluations of the effectiveness of the Board, reviewing and recommending to the Board policies and practices to be followed in carrying out the Trustees' duties and responsibilities and reviewing and making recommendations to the Board regarding the compensation of the Trustees who are not affiliated with the Funds' investment advisors. The Governance Committee will consider candidates for Trustee recommended by shareholders. Written recommendations with supporting information should be directed to the Committee, in care of the Funds. For the fiscal year ended October 31, 2005, the Governance Committee convened five times.

Investment personnel who manage the Funds attend IOC meetings from time to time to assist each IOC in its review of the Funds. Each IOC

COMPENSATION

As of the Funds' most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

All of the Funds offer Class A, Class B, Class C, Class T, Class G and Class Z shares. The Funds may in the future offer other classes of shares.

The Trustees have approved a 12b-1 Plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, each Fund pays CMD monthly a service fee at an annual rate of 0.25% of each Fund's average daily net assets attributed to Class A, B and C shares.

The Funds also pay CMD monthly a distribution fee at an annual rate of 0.75% of each Fund's average daily net assets attributed to Class B and Class C shares.

Each Fund may pay CMD distribution and service fees up to a maximum of 1.15% of such Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services). Each Fund does not intend to pay more than a total of 0.80% for Class G distribution and shareholder service fees during the current fiscal year.

CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to FSFs and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees.

The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of Fund shares. The Trustees believe the Plan could be a significant factor in the growth and retention of the Funds' assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at

v

a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class T shares of the Funds are subject to a shareholder servicing fee pursuant to a Shareholder Servicing Plan. Under the Shareholder Servicing Plan, a Fund may enter into agreements with institutions pursuant to which an institution agrees to provide certain administrative and support services to its customers who are the beneficial owners of Class T shares. Services provided by such institutions to their customers include aggregating and processing purchase and redemption requests and placing net purchase and redemption orders. In return for providing these services, the Fund agrees to pay each institution a fee at an annual rate of up to 0.50% of the average daily net assets attributable to Class T shares owned beneficially by the institution's customers.

Current service arrangements are limited to payments of 0.15% for all the Funds except the Rhode Island Fund, whose service arrangement payments are limited to 0.00%.

Under the Shareholder Servicing Plan, the Trustees must review, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which those expenditures were made. The initial term of the Shareholder Servicing Plan is one year and it will continue in effect from year to year after its initial one-year term provided that its continuance is specifically approved at least annually by a majority of the Trustees, including a majority of the Independent Trustees who have no direct or indirect financial interest in the operation of the Shareholder Servicing Plan or in any agreement related to it. Any material amendment to the Shareholder Servicing Plan must be approved in the same manner. The Shareholder Servicing Plan is terminable at any time with respect to any Fund by a vote of a majority of the Independent Trustees. While the Shareholder Servicing Plan is in effect, only the Independent Trustees may select and nominate any future Independent Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class G shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on when you purchased your shares that were exchanged for Class G shares. Class T shares are offered at net asset value plus varying sales charges which may include a CDSC. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses.

No CDSC will be imposed on shares derived from reinvestment of distributions or amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years, after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

Eight years, depending on when you purchased your shares that were exchanged for Class G shares, after the end of the month in which you purchased your shares that were exchanged for Class G shares, such Class G shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class T shares having an equal value, which are not subject to the distribution fee.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

2

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

3

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a

4

segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

5

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain

6

private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by

the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by

8

mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the

9

underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

10

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest ra8te and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

11

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

12

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

13

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the

14

Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

15

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

16

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

17

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

18

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking

19

into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and
(4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets. The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

20

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ( "ADRs ") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ( "EDRs "), which are sometimes

21

referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested (x) in the securities of any issuer, other than U.S. government securities or other regulated investment companies, or (y) in the securities of one or more "qualified publicly traded partnership" (as defined below); or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid -- generally, ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and any net tax-exempt interest, income, for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that

22

derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of long-term capital gains

23

will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market

24

discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

25

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income, possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, for taxable years of the Fund before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

26

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

27

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37(1)/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS Columbia Management Advisors, LLC ("Columbia Advisors" or "CMA" or the "Advisor"), located at 100 Federal Street, Boston, Massachusetts 02110 is the Advisor to the Funds. The Advisor provides administrative and management services to the Funds. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005 Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

Trustee Positions

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds a group of 2 registered closed-end funds sponsored by an affiliate of the Advisor.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Mr. Theobald serves as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expenses Committee receives a supplemental retainer at the annual rate of $15,000; the chairs of the Compliance Committee and the Governance Committee each receive supplemental retainers at the annual rate of $10,000. Members of each committee, including the Investment Oversight Committee, receive $2,500 for each committee meeting and $1,000 for each telephonic committee meeting. The Audit Committee chair receives a supplement of $500 for each Audit Committee meeting. Committee members receive $2,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

35

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold -- for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

37

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions

38

with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such

39

indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is

40

prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov; and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                           Frequency of
Type of Fund                 Information Provided           Disclosure            Date of Web Posting
------------         -----------------------------------   ------------   ----------------------------------
Equity Funds         Full portfolio holdings information      Monthly      30 calendar days after month-end
Fixed Income Funds   Full portfolio holdings information     Quarterly    60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

41

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of trading on the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities. Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Greater China Fund).

42

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS.

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

43

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned

47

by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD

48

account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of

49

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

50

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares -- Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise after the purchase of shares
(ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase and (iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under
Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

51

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under
Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. The $5,000 minimum account balance requirement has been waived for wrap accounts. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

52

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000 for non-money market funds. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

53

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                 Reallowance to
                                     Reallowance to Dealers    Dealers As A % of
                                    As A % of Offering Price   Offering Price Per
Amount of Transaction                Per Share - Bond Funds    Share - Equity Funds
---------------------               ------------------------   --------------------
Less than $50,000                             4.25                    5.00
$50,000 but less than $100,000                3.75                    3.75

$500,000 but less than $1,000,000             1.75                    1.75
$1,000,000 and over                           0.00                    0.00

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % Deducted When
Holding Period After Purchase   Shares Are Sold
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Longer than six years                 None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares six years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

54

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                % Deducted When
Holding Period After Purchase   Shares Are Sold
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates -- (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A

56

shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange. Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

57

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB-rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing

59

credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

60

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

61

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

62

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality

Prime-2 Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated "F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

63

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, and D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC.

65

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section
IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in
Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

66

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

67

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

68

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

69

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

70

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes-Oxley Act of 2002 have been provided.

71

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

72

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

77

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

9. The second paragraph of the section entitled "Other Disclosures," a subsection of "Disclosure of Portfolio Information," is revised in its entirety to read:

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

ORGANIZATION AND HISTORY

The "Columbia Fund Complex" includes all of the registered investment companies to which the Advisor and its affiliates provide investment advisory services.

Trust V is a Massachusetts business trust organized in 1986. The Connecticut Fund, the Massachusetts Fund and the New York Fund are open-end, management investment companies and are non-diversified series of Trust V and represent the entire interest in a separate series of Trust V. The Connecticut Fund commenced investment operations on November 1, 1991; the Massachusetts Fund commenced investment operations on April 10, 1987, and the New York Fund commenced investment operations on September 26, 1986. Each of the Connecticut Fund, the Massachusetts Fund and the New York Fund expects to reorganize as series of Columbia Funds Series Trust I in 2006.

Effective April 1, 1999, Trust V changed its name from Colonial Trust V to Liberty Funds Trust V. Trust V changed its name to its current name on October 13, 2003. Effective July 14, 2000, Colonial Connecticut Tax-Exempt Fund, Colonial Massachusetts Tax-Exempt Fund and Colonial New York Tax-Exempt Fund changed their names to Liberty Connecticut Tax-Exempt Fund, Liberty Massachusetts Tax-Exempt Fund and Liberty New York Tax-Exempt Fund, respectively. Each of the aforementioned Funds changed its name to its current name on October 13, 2003.

Columbia Funds Series Trust I is a Massachusetts business trust organized in 1987. The California Fund is an open-end, management investment company and is a non-diversified series of Columbia Funds Series Trust I and represents the entire interest in a separate series of Columbia Funds Series Trust I. The California Fund commenced investment operations as a series of Columbia Funds Series Trust I on September 19, 2005. Prior to September 19, 2005 (the "California Fund Reorganization Date"), the California Fund was organized as a series of Columbia Funds Trust V that commenced investment operations on June 16, 1986. The information provided for the California Fund in this SAI for periods prior to the California Fund Reorganization Date relates to the predecessor fund of the same name. Effective October 13, 2003, Columbia Funds Series Trust I, which had prior to that date been named "Liberty-Stein Roe Funds Municipal Trust" changed its name to "Columbia Funds Trust IX." Effective September 19, 2005, the name of the aforementioned Trust changed from "Columbia Funds Trust IX" to its current name.

b


The Connecticut Fund, the Massachusetts Fund and the Connecticut Fund offer three classes of shares -- Class A, B and C shares. The California Fund offers four classes of shares -- Class A, B, C and Z shares.

Neither Trust V nor Columbia Funds Series Trust I is required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of the Funds and any other series of the trust of which it is a series and that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of a Fund's shares may call meetings to consider removal of trustees. Under certain circumstances, a trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

INVESTMENT GOAL AND POLICIES OF THE FUNDS

The Prospectus describes each Fund's investment goal and investment strategies and risks.

Short-Term Trading
Lower-Rated Debt Securities

Zero Coupon Securities (Zeros)
Step Coupon Bonds (Steps)

Mortgage-Backed Securities

Except as indicated below under "Fundamental Investment Policies of the Funds," the Funds' investment policies are not fundamental and the Trustees may change the investment policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES OF THE FUNDS

The Investment Company Act of 1940, as amended (1940 Act), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either:
(a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

c

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the Act, the rules and regulations thereunder and any applicable exemptive relief.

In addition to the fundamental investment restrictions enumerated above, each Fund will:

7. Under normal circumstances, invest at least 80% of its total assets in State Bonds, subject to applicable State requirements.

OTHER INVESTMENT POLICIES OF THE FUNDS

As non-fundamental investment policies, which may be changed without a shareholder vote, each Fund may not:

1. Purchase securities on margin, but the Fund may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;

2. Have a short securities position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and

3. Invest more than 15% of its net assets in illiquid assets.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, the issuer is the entity whose revenues support the security.

Notwithstanding the investment policies of the Funds, each Fund (other than the California Fund) may invest substantially all of its investable assets in another investment company that has substantially the same investment goal, policies and restrictions as each Fund.

CALIFORNIA TAX CONSIDERATIONS

It is the policy of the Fund to meet all applicable requirements of the Internal Revenue Code of 1986, as amended (the Code) and the California Revenue and Taxation Code for shareholders to be relieved of the obligation to pay regular federal income taxes and California personal income tax on amounts distributed to them which are derived from tax-exempt interest income. That is, the Fund will have at least 50% of its total assets invested in tax-exempt bonds and U.S. government obligations whose interest is excluded from income for California personal income tax purposes ("California Tax-Exempt Bonds") at the end of each quarter.

California law provides that, to the extent distributions by the Fund are derived from interest on California Tax-Exempt Bonds and are designated as such, such distributions shall be exempt from California personal income taxes. For California personal income tax purposes, distributions derived from other investments and distributions from any net realized capital gains will be taxable, whether paid in cash or reinvested in additional shares.

d

Interest derived from California Tax-Exempt Bonds is not subject to the California alternative minimum tax and California personal income tax does not apply to any portion of Social Security or railroad retirement benefits. Under the Code, any portion of interest on indebtedness (including insurance policy loans) incurred or continued to purchase or carry shares of the Fund which is deemed to relate to tax-exempt dividends will not be deductible. For California personal income tax purposes none of such interest will be deductible. Depending on the circumstances, the Internal Revenue Service or California Franchise Tax Board may consider shares to have been purchased or carried with borrowed funds even though the shares are not directly traceable to the borrowed funds. Shareholders who are, within the meaning of Section 147 of the Code, "substantial users" (or "related persons" of substantial users) of facilities financed by industrial development bonds should consult their tax advisors as to whether the Fund is a desirable investment.

Corporations that are subject to either the California franchise tax or the California corporate income tax and that invest in the Fund will generally be taxed on distributions other than dividends derived from interest paid on California Tax-Exempt Bonds. Corporations that are subject to the California franchise tax will also be taxed on dividends derived from interest paid on California Tax-Exempt Bonds.

The foregoing is a general summary of the California tax consequences of investing in the Fund. You should consult with your tax adviser regarding special questions as to federal, state or local taxes.

CONNECTICUT TAX CONSIDERATIONS

Distributions received by shareholders from the Fund that qualify as exempt-interest dividends for federal income tax purposes are exempt from the Connecticut personal income tax to the extent that they are derived from interest on obligations issued by or on behalf of the State of Connecticut, any political subdivision thereof, or public instrumentality, state or local authority, district or similar public entity created under the laws of Connecticut ("Connecticut Tax-Exempt Bonds") or from obligations the interest on which states are prohibited from taxing by federal law. Other distributions, whether received in cash or additional shares, are subject to the Connecticut personal income tax, except that, in the case of shares of the Fund held by shareholders as capital assets, those distributions that are treated as capital gain dividends for federal income tax purposes are not subject to the tax to the extent that they are derived from the sale or exchange of Connecticut Tax-Exempt Bonds. Distributions that are subject to the federal alternative minimum tax could cause liability for the net Connecticut minimum tax, with the exception of exempt-interest dividends that are exempt from the Connecticut personal income tax.

Distributions from investment income and capital gains, including dividends derived from interest paid on Connecticut Tax-Exempt Bonds, are included in gross income for purposes of the Connecticut corporation business tax. However, seventy percent of such distributions are deductible for purposes of this tax, provided that they are treated for federal income tax purposes as dividends but not as exempt-interest dividends or capital gain dividends, but no deduction is allowed for expenses related thereto.

Shares of the Fund are not subject to property taxation by Connecticut or its political subdivisions.

The foregoing is a general summary of the Connecticut tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

MASSACHUSETTS TAX CONSIDERATIONS

Distributions received by shareholders from the Fund are exempt from Massachusetts personal income tax to the extent that they are derived from interest on obligations of the Commonwealth of Massachusetts, its political subdivisions, or agencies or instrumentalities of the foregoing, or obligations of certain U.S. territories and possessions (including the Commonwealth of Puerto Rico, the United States Virgin Islands or Guam), and are designated as such. The Fund believes that gains it realizes on the sale of certain Tax-Exempt Bonds are exempt from Massachusetts's personal income taxation and will designate them as such when those gains are distributed to shareholders.

Distributions from investment income and capital gains, including dividends derived from interest paid on Tax-Exempt Bonds, may be subject to Massachusetts corporate excise tax.

Long-term capital gains that are subject to tax in Massachusetts will be taxed at 5.3%.

The foregoing is a general summary of the Massachusetts tax consequences of investing in the Fund. You should consult your tax advisor regarding specific questions as to federal, state or local taxes.

e


NEW YORK TAX CONSIDERATIONS

New York law provides that, to the extent distributions by a regulated investment company are derived from interest on debt obligations issued by the State of New York or its political subdivisions or certain other governmental entities (for example, the Commonwealth of Puerto Rico, the United States Virgin Islands or Guam), the interest on which was excludable from gross income for purposes of both federal income taxation and New York State and City personal income taxation ("New York Tax-Exempt Bonds") and designated as such, such distributions shall be exempt from New York State and City personal income taxes. For New York State and City personal income tax purposes, distributions derived from investments other than New York Tax-Exempt Bonds and distributions from the excess of net short-term capital gains over net long-term capital losses will be taxable as ordinary income. For New York State and City personal income tax purposes, distributions of net long-term capital gains will be taxable at the same rates as ordinary income. The tax treatment of distributions you receive is the same whether they are paid in cash or reinvested in additional shares. Interest on indebtedness incurred by a shareholder to purchase or carry shares of the Fund is not deductible for New York State and City personal income tax purposes. Distributions by the Fund from investment income and capital gains, including exempt-interest dividends, are included in a corporation's net investment income for purposes of calculating such corporation's New York State franchise taxes and the New York City General Corporation Tax if received by a corporation subject to those taxes, and will be subject to such taxes to the extent that a corporation's net investment income is allocated to New York State and/or New York City. Distributions by the Fund may be subject to state taxes in states other than New York and to local taxes in cities other than New York City, both for individual and corporate shareholders.

The foregoing is a summary of certain New York State and New York City income tax consequences of investing in the Fund. Shareholders should consult their tax advisor to determine the precise effect of an investment in the Fund on their particular tax situation.

FUND CHARGES AND EXPENSES

Effective November 1, 2003, the Board of Trustees approved a new management fee structure for the Funds, as follows: 0.50% of the first $1 billion of the combined average daily net assets of the Funds, plus 0.45% of the next $2 billion of the combined average daily net assets of the Funds, plus 0.40% of the combined average daily net assets of the Funds in excess of $3 billion.

Prior to November 1, 2003, the Funds paid the Advisor a monthly fee based on the Funds' combined average daily net assets, determined at the close of each business day during the month at the following annual rates: 0.50% on the first $2 billion and 0.45% of any excess over $2 billion.

The Advisor provides certain pricing and bookkeeping services to each Fund. Effective November 1, 2005, each Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Funds will continue to receive substantially the same pricing, bookkeeping and administrative services as they currently receives under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, each Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for fund accounting services, $25,000 plus an additional monthly fee based on each Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. Each Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement.

Prior to November 1, 2005, under a pricing and bookkeeping agreement with the Funds, the Advisor received from each Fund a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

- An annual flat fee of $10,000, paid monthly; and

- In any month that a Fund has average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

f


Under the agreement in place prior to November 1, 2005, each Fund reimbursed the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for each Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Funds entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to each Fund (and will continue to retain Boston Financial Data Services, Inc. to assist it) for a reduced fee. The new fee is $15.23 per open account per annum, payable monthly. In addition, each Fund may pay CMS the fees and expenses it pays to third-party dealer firms that maintain omnibus accounts with the Funds, subject to a cap equal to 0.11% of each Fund's net assets represented by the account. The Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Funds and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Funds.

Prior to November 1, 2005, under the transfer agency fee arrangement between CMS and the Funds, each Fund paid the following Fees:

- An annual open account fee of $34 per open account plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CFS.

Prior to November 1, 2003, each Fund paid a shareholders' servicing and transfer agency fee to CFS as follows:

- An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus

- A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of the Fund for such month; plus

- The Fund's allocated share of CFS' out-of-pocket expenses, including fees payable to DST Systems, Inc. ("DST") under a remote services agreement with DST.

COMPENSATION

As of each Fund's most recent fiscal year end, the portfolio manager received all of his compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing a manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

Gary Swayze -- The New York Fund        Lehman Municipal Bond Index      Lipper New York Municipal Debt Category

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

Each Fund offers Class A, Class B and Class C shares, and the California Fund offers an additional class of shares, Class Z shares. Each Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan ("Plan") for each Fund pursuant to Rule 12b-1 under the Act. Under the Plan, each Fund pays CMD monthly a service fee at an annual rate of 0.10% of each Fund's net assets attributed to the outstanding shares of each class on December 1, 1994, and a service fee of 0.25% of the average daily net assets attributed to Class A, Class B and Class C shares issued thereafter. The Funds also pay CMD monthly a distribution fee at an annual rate of 0.75% of each Fund's average daily net assets attributed to each Fund's Class B and Class C shares. CMD has voluntarily agreed to waive a portion of each Fund's Class C share distribution fee so that it does not exceed 0.45% annually. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial

s


service firms ("FSFs") and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees.

The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of each Fund's shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in a more advantageous expense ratio and increased investment flexibility which could benefit each class of each Fund's shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares, and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC for periods up to six years after the purchase. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs and initial sales charge are described in the Prospectuses for each Fund.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

A certain number of years, depending on the program you purchased your shares under, after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

2

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

3

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a

4

segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

5

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain

6

private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by

7

the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by

8

mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the

9

underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

10

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

11

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

13

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the

14

Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at anytime during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

15

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

16

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

17

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

18

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking

19

into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and
(4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets. The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

20

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes

21

referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested (x) in the securities of any issuer, other than U.S. government securities or other regulated investment companies, or (y) in the securities of one or more "qualified publicly traded partnership" (as defined below); or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid -- generally, ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and any net tax-exempt interest, income, for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that

22

derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of long-term capital gains

23

will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market

24

discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

25

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income, possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, for taxable years of the Fund before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

26

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

27

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

Trustee Positions

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds a group of 2 registered closed-end funds sponsored by an affiliate of the Advisor.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Mr. Theobald serves as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expenses Committee receives a supplemental retainer at the annual rate of $15,000; the chairs of the Compliance Committee and the Governance Committee each receive supplemental retainers at the annual rate of $10,000. Members of each committee, including the Investment Oversight Committee, receive $2,500 for each committee meeting and $1,000 for each telephonic committee meeting. The Audit Committee chair receives a supplement of $500 for each Audit Committee meeting. Committee members receive $2,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

35

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

36

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold -- for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

37

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions

38

with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such

39

indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is

40

prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov; and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                           Frequency of
Type of Fund                 Information Provided           Disclosure            Date of Web Posting
------------------   -----------------------------------   ------------   ----------------------------------
Equity Funds         Full portfolio holdings information      Monthly       30 calendar days after month-end
Fixed Income Funds   Full portfolio holdings information     Quarterly    60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

41

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of trading on the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities. Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS.

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

43

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned

47

by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1,1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD

48

account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at NAV to the following individuals, whether currently employed or retired:
Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

50

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares -- Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code).

(ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee.

If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under
Section 501 (c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under
Section 501 (c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. The $5,000 minimum account balance requirement has been waived for wrap accounts. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

52

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000 for non-money market funds. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

53

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                  Reallowance to
                                     Reallowance to Dealers      Dealers As A % of
                                    As A % of Offering Price    Offering Price Per
Amount of Transaction                Per Share - Bond Funds    Share - Equity Funds
---------------------------------   ------------------------   --------------------
Less than $50,000                             4.25                     5.00
$50,000 but less than $100,000                3.75                     3.75

$250,000 but less than $500,000               2.00                     2.00
$500,000 but less than $1,000,000             1.75                     1.75
$1,000,000 and over                           0.00                     0.00

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % Deducted When
Holding Period After Purchase   Shares Are Sold
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Longer than six years                 None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares six years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

54

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                % Deducted When
Holding Period After Purchase   Shares Are Sold
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates -- (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

55

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Through sixth year                    1.00
Longer than six years                 0.00

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A

56

shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange. Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

57

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

58

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB-rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing

59

credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

60

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1,A1 andBaa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

61

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

62

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest

Quality Prime-2

Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1,2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated "F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

63

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC.

65

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section
IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in
Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

66

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

67

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

68

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

69

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

70

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes-Oxley Act of 2002 have been provided.

71

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries. o Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

72

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

Proxy Contests:

CMA will vote on a CASE-BY-CASE basis proposals for proxy contests, considering the following factors:

- Past performance relative to its peers

- Market in which fund invests

- Measures taken by the board to address the pertinent issues (e.g., closed-end fund share market value discount to NAV)

- Past shareholder activism, board activity and votes on related proposals

- Strategy of the incumbents versus the dissidents

- Independence of incumbent directors; director nominees

- Experience and skills of director nominees

- Governance profile of the company

- Evidence of management entrenchment

Converting Closed-end Fund to Open-end Fund:

CMA will vote conversion proposals on a CASE-BY-CASE basis, considering the following factors:

- Past performance as a closed-end fund

- Market in which the fund invests

- Measures taken by the board to address the discount

- Past shareholder activism, board activity, and votes on related proposals.

Investment Advisory Agreements:

CMA will vote investment advisory agreements on a CASE-BY-CASE basis, considering the following factors:

- Proposed and current fee schedules

- Fund category/investment objective

- Performance benchmarks

- Share price performance as compared with peers

- Resulting fees relative to peers

- Assignments (where the adviser undergoes a change of control)

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

77

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940 (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or
(2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.
2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.
3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.
4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.
5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.
6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.
7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief. For purposes of this restriction, tax-exempt securities that are supported solely by the revenues of a particular private entity will be deemed to have been issued by that entity.

In addition to the above listed fundamental investment policies, each Fund:

8. Will, under normal circumstances, invest at least 80% of its total assets in tax-exempt bonds.

OTHER INVESTMENT POLICIES
As non-fundamental investment policies which may be changed without a shareholder vote, each Fund may not:

1. Purchase securities on margin, but it may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;
2. Have a short securities position, unless a Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and
3. Invest more than 15% of its net assets in illiquid assets.

c

Notwithstanding the investment policies and restrictions of the Funds, each Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Funds.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment.

FUND CHARGES AND EXPENSES
Under the Tax-Exempt and the Insured Fund's Management Agreement, the Trust pays the Advisor a monthly fee based on the combined average daily net assets, proportionately allocated among the Tax-Exempt Fund and the Insured Fund at the following annual rates (subject to any reductions that the Advisor may agree to periodically):

Average Net Assets                    Annual Fee Rate
------------------                    ---------------
Under $500 million                         0.55%
$500 million but less than $1 billion      0.50%
$1 billion but less than $1.5 billion      0.47%
$1.5 billion but less than $3 billion      0.44%
$3 billion but less than $6 billion        0.43%
In excess of $6 billion                    0.42%

Prior to November 1, 2004, the Trust paid the Advisor a monthly fee based on the combined average daily net assets, proportionately allocated among the Tax-Exempt Fund and the Insured Fund at the following annual rates (subject to any reductions that the Advisor may agree to periodically):

Average Net Assets     Annual Fee Rate
------------------     ---------------
First $1 billion            0.60%
Next $2 billion             0.55%
Next $1 billion             0.50%
Excess over $4 billion      0.45%

The Advisor is responsible for providing certain pricing and bookkeeping services to the Funds. Effective November 1, 2005, the Funds entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Funds will continue to receive substantially the same pricing, bookkeeping and administrative services as they currently receive under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street will continue to provide these services to the Funds. For services provided under the Pricing and Bookkeeping Agreement, the Funds will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for Fund accounting services, $25,000 plus an additional monthly fee based on each Fund's net asset value ("Fund Accounting Fee"); and (ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. The Funds will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

d

For periods prior to November 1, 2005, each Fund paid the Advisor fees under a similar pricing and bookkeeping agreement with the Funds, that consisted of a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

. An annual flat fee of $10,000, paid monthly; and
. In any month that a Fund has average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

Each Fund reimburses the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Funds. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Funds have entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to the Funds (and will continue to retain Boston Financial Data Services, Inc. to assist them) for a reduced fee. The new fee is $15.23 per account per annum, payable monthly. In addition, the Funds may pay CMS the fees and expenses they pay to third-party dealer firms that maintain omnibus accounts with the Funds, subject to a cap equal to 0.11% of each Fund's net assets represented by the account. The Funds will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Funds and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Funds.

Prior to November 1, 2005, each Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

An annual open account fee of $34 per open account plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

Prior to November 1, 2003, each Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

. An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
. An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
. A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus
. A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of each Fund for such month; plus
. Each Fund's allocated share of CMS' out-of-pocket expenses, including fees payable to DST Systems, Inc. (DST) under a remote services agreement with DST.

For the fiscal year ended November 30, 2005, the Audit Committee convened seven times.

Governance Committee

Messrs. Lowry, Mayer, Simpson and Theobald are members of the Governance Committee of the Board of Trustees of the Funds. The Governance Committee's functions include recommending to the Trustees nominees for independent Trustee positions and for appointments to various committees, performing periodic evaluations of the effectiveness of the Board, reviewing and recommending to the Board policies and practices to be followed in carrying out the Trustees' duties and responsibilities and reviewing and making recommendations to the Board regarding the compensation of the Trustees who are not affiliated with the Funds' investment advisors. The Governance Committee will consider candidates for Trustee recommended by shareholders.

Compensation

As of the Funds' most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12b-1 Plan, CDSCs and Conversion of Shares

Each Fund offers three classes of shares--Class A, Class B and Class C. In addition, the Tax-Exempt Fund offers Class Z shares. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan ("Plan") pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the Tax-Exempt Fund and the Insured Fund each pay CMD monthly a service fee at an annual rate of 0.20% of net assets attributed to each Class of shares. Each Fund also pays CMD monthly a distribution fee at the annual rate of 0.75% of average daily net assets attributed to Class B and Class C shares. CMD has voluntarily agreed to waive a portion of the Class C share distribution fee so that it does not exceed 0.60% (Tax-Exempt Fund) and 0.45% (Insured Fund), annually. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms ("FSFs") and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may in some cases realize a profit from the fees.

The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of the Funds' shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in a more advantageous expense ratio and increased investment flexibility which could benefit each class of the Funds' shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan ("Independent Trustees"), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within six years after purchase. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. The CDSCs and initial sales charges are described in the Prospectuses.

m

No CDSC will be imposed on an amount which represents an increase in the value of the shareholder's account resulting from capital appreciation above the amount paid for the shares. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Series Trust I, Columbia Funds Institutional Trust, SteinRoe Variable Investment Trust and Liberty Variable Investment Trust (each a Trust and together, the Trusts). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

2

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a

4

segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

5

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain

6

private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by

7

the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by

8

mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES

Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition,

9

if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

10

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

11

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

12

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

13

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the

14

Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

15

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

16

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

17

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

18

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking

19

into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and
(4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets. The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

20

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes

21

referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested (x) in the securities of any issuer, other than U.S. government securities or other regulated investment companies, or (y) in the securities of one or more "qualified publicly traded partnership" (as defined below); or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid -- generally, ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and any net tax-exempt interest, income, for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that

22

derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of long-term capital gains

23

will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market

24

discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

25

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income, possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, for taxable years of the Fund before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

26

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

27

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributors and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

Trustee Positions

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds, a group of 2 registered closed-end funds sponsored by an affiliate of the Advisor.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Mr. Theobald serves as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expenses Committee receives a supplemental retainer at the annual rate of $15,000; the chairs of the Compliance Committee and the Governance Committee each receive supplemental retainers at the annual rate of $10,000. Members of each committee, including the Investment Oversight Committee, receive $2,500 for each committee meeting and $1,000 for each telephonic committee meeting. The Audit Committee chair receives a supplement of $500 for each Audit Committee meeting. Committee members receive $2,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

35

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

36

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold -- for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

37

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions

38

with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such

39

indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is

40

prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov; and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                                   Frequency of
Type of Fund                        Information Provided            Disclosure           Date of Web Posting
------------                ------------------------------------   ------------   ----------------------------------
Equity Funds                 Full portfolio holdings information      Monthly       30 calendar days after month-end

Fixed Income Funds           Full portfolio holdings information    Quarterly     60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

41

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare Investor Services, LLC), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of trading on the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities. Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Greater China Fund).

42

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS.

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

43

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned

47

by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD

48

account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares -- Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares
(ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND (iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under
Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

51

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under
Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. The $5,000 minimum account balance requirement has been waived for wrap accounts. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

52

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00 p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000 for non-money market funds. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

53

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                                       Reallowance to

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates -- (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A

56

shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange. Consult CMS before requesting an exchange.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a

57

meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing

59

credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

60

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

61

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

62

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality

Prime-2 Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated "F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

63

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.


1 The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

2 A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC.

65

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

67

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

68

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

69

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

70

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes-Oxley Act of 2002 have been provided.

71

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

72

CMA will WITHHOLD votes from directors who:

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

77

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987. The Fund was originally organized as a series of another Massachusetts business trust prior to its reorganization as a series of the Trust on March 27, 2006. The Fund is an open-end, diversified management investment company, representing the entire interest in a separate series of the Trust. The Fund commenced investment operations on August 31, 1981.

Effective October 13, 2003, the Trust changed its name from "Liberty-Stein Roe Funds Municipal Trust" to "Columbia Funds Trust IX." Effective September 19, 2005, the name of the Trust was changed from "Columbia Funds Trust IX" to its current name.

INVESTMENT GOALS AND POLICIES
The Prospectuses describe the Fund's investment goals, investment strategies and risks. Part 1 of this SAI includes additional information concerning, among other things, the investment policies of the Fund. Part 2 contains additional information about the following securities and investment techniques that may be utilized by the Fund:

Options (on Indices and Securities)
Foreign Securities
Foreign Currency Transactions
Repurchase Agreements
Rule 144A Securities
Forward Commitments
Money Market Instruments

Except as indicated below under "Fundamental Investment Policies," the Fund's investment policies are not fundamental and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES
The Investment Company Act of 1940, as amended ("1940 Act"), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

The Fund may not, as a fundamental investment policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

b


2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

The Fund may, as a matter of fundamental policy, concentrate more than 25% of its total assets in any single industry.

OTHER INVESTMENT POLICIES
As non-fundamental investment policies, which may be changed without a shareholder vote, the Fund may not:

1. Purchase securities on margin, but it may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;

2. Have a short securities position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and

3. Invest more than 15% of its net assets in illiquid assets.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

SPECIAL TAX CONSIDERATIONS
The Fund may designate dividends as eligible for the dividends-received deduction only to the extent that the Fund receives dividends for which the Fund would be entitled to the dividends-received deduction if the Fund were a regular corporation and not a regulated investment company. The dividends-received deduction is available with respect to dividends received from domestic corporations subject to U.S. federal income tax and is not available to certain special corporations, such as Subchapter S corporations, to other entities or to individuals. There can be no assurance that the dividends-received deduction will not be reduced or eliminated in the future.

For dividends designated by the Fund as eligible for the dividends-received deduction to qualify as such by a particular shareholder, the shareholder must meet certain holding period requirements. The basis of a shareholder's shares may be reduced by an amount equal to the non-taxed portion of "extraordinary dividends" eligible for the dividends-received deduction.

c

PORTFOLIO TURNOVER
Portfolio turnover is included in the Prospectuses under "Financial Highlights." High portfolio turnover may cause the Fund to realize capital gains, which if realized and distributed by the Fund, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Fund.

FUND CHARGES AND EXPENSES
Effective November 1, 2003, under the Fund's management agreement, the Fund pays the Advisor a monthly fee based on the average daily net assets at the annual rate of 0.65% on the first $1 billion and 0.60% of any excess of $1 billion.

Prior to November 1, 2003, under the Fund's management agreement, the Fund paid the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of 0.65%. The Advisor had voluntarily agreed to waive its fee so that its actual fee would not exceed 0.60% of average daily net assets on assets in excess of $1 billion.

The Advisor is responsible for providing certain pricing and bookkeeping services to the Fund. Effective November 1, 2005, the Fund entered into a Pricing and Bookkeeping Agreement and an Administrative Agreement. Under these agreements, the Fund will continue to receive substantially the same pricing, bookkeeping and administrative services as it currently receives under the Agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated the pricing and bookkeeping function to State Street Bank and Trust Company ("State Street"). The Advisor pays fees to State Street under the Outsourcing Agreement. The Advisor and State Street Bank and Trust Company will continue to provide these services to the Fund. For services provided under the Pricing and Bookkeeping Agreement, the Fund will pay the Advisor or to such other person(s) as the Advisor may direct an annual fee, payable monthly, consisting of: (i) for Fund accounting services, $25,000 plus an additional monthly fee based on the Fund's net asset value ("Fund Accounting Fee"); and
(ii) for financial reporting services, $13,000 ("Financial Reporting Fee"); provided that during any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee shall not exceed $140,000. The Fund will bear certain reimbursable costs and expenses as provided in the Pricing and Bookkeeping Agreement and the Administrative Agreement.

For periods prior to November 1, 2005, the Fund paid the Advisor fees under a similar pricing and bookkeeping agreement with the Fund, that consisted of a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

. An annual flat fee of $10,000, paid monthly; and
. In any month that the Fund has average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

The Fund reimburses the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Fund. Its address is P.O. Box 8081, Boston, Massachusetts 02266-8081. Effective November 1, 2005, the Fund has entered into a new agreement with CMS, under which CMS will continue to provide transfer agency, dividend disbursing agency and shareholders' servicing agency services to the Fund (and will continue to retain Boston Financial Data Services, Inc. to assist them) for a reduced fee. The new fee is $15.23 per account per annum, payable monthly. In addition, the Fund may pay CMS the fees and expenses it pays to third-party dealer firms that maintain omnibus accounts with the Fund, subject to a cap equal to 0.11% of the Fund's net assets represented by the account. The Fund will also pay certain reimbursable out-of-pocket expenses to CMS, and CMS may also retain as additional compensation for its services revenues for fees for wire, telephone and redemption orders, IRA trustee agent fees and account transcripts due CMS from shareholders of the Fund and credits (net of bank charges) earned with respect to balances in accounts CMS maintains in connection with its services to the Fund.

Prior to November 1, 2005, the Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

. An annual open account fee of $28 per open account, plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

d

Prior to November 1, 2003, the Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

. An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
. An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus
. A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus
. A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of the Fund for such month; plus

. The Fund's allocated share of CMS' out-of-pocket expenses, including fees payable to DST Systems, Inc. (DST) under a remote services agreement with DST.

Compensation

As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmark noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

-----------------------------------------------
Portfolio Manager  Performance Benchmark
-----------------------------------------------
 Edward Y. Paik   S&P Utilities and S&P Telecom

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12b-1 Plan, CDSCs and Conversion of Shares

The Fund offers four classes of shares--Class A, Class B, Class C and Class Z. The Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for each class except Class Z shares. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.25% of the average daily net assets attributed to Class A, Class B and Class C shares. The Fund also pays CMD monthly a distribution fee at the annual rate of 0.75% of the average daily net assets attributed to Class B and Class C shares. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Fund to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of Fund shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of the Fund's assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Fund and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value subject to a CDSC if redeemed within a certain number of years after purchase depending on the program under which you purchased your shares. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectus for Class A, Class B and C shares for the Fund.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee. See the Prospectus for a description of the different programs.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Series Trust I, Columbia Funds Institutional Trust, SteinRoe Variable Investment Trust and Liberty Variable Investment Trust (each a Trust and together, the Trusts). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

2

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

3

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a

4

segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

5

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain

6

private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by

7

the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by

8

mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES

Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition,

9

if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

10

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

12

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

13

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the

14

Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

15

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

16

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

17

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

18

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking

19

into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and
(4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets. The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

20

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes

21

referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested (x) in the securities of any issuer, other than U.S. government securities or other regulated investment companies, or (y) in the securities of one or more "qualified publicly traded partnership" (as defined below); or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid -- generally, ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and any net tax-exempt interest, income, for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that

22

derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of long-term capital gains

23

will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market

24

discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

25

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income, possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, for taxable years of the Fund before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

27

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributors and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

Trustee Positions

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds, a group of 2 registered closed-end funds sponsored by an affiliate of the Advisor.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Mr. Theobald serves as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expenses Committee receives a supplemental retainer at the annual rate of $15,000; the chairs of the Compliance Committee and the Governance Committee each receive supplemental retainers at the annual rate of $10,000. Members of each committee, including the Investment Oversight Committee, receive $2,500 for each committee meeting and $1,000 for each telephonic committee meeting. The Audit Committee chair receives a supplement of $500 for each Audit Committee meeting. Committee members receive $2,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

35

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

36

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold -- for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

37

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions

38

with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such

39

indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is

40

prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov; and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                                   Frequency of
Type of Fund                        Information Provided            Disclosure           Date of Web Posting
------------                ------------------------------------   ------------   ----------------------------------
Equity Funds                 Full portfolio holdings information      Monthly       30 calendar days after month-end

Fixed Income Funds           Full portfolio holdings information    Quarterly     60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

41

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare Investor Services, LLC), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of trading on the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities. Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Greater China Fund).

42

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS.

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

43

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned

47

by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD

48

account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares -- Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares
(ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND (iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under
Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

51

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under
Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. The $5,000 minimum account balance requirement has been waived for wrap accounts. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

52

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00 p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000 for non-money market funds. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

53

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                                       Reallowance to

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares six years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

54

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                          % Deducted When
Holding Period After Purchase             Shares Are Sold
-----------------------------             ---------------
Through first year                             5.50

Through second year                            5.00

Through third year                             4.00

Through fourth year                            3.00

Through sixth year                             1.00

Through the seventh year                       None

Longer than seven years                        None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates -- (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A

56

shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange. Consult CMS before requesting an exchange.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a

57

meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing

59

credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

60

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

61

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

62

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality

Prime-2 Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated "F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

63

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

64

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.


1 The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

2 A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC.

65

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in
Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in
Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

66

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

67

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

68

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

69

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

70

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes-Oxley Act of 2002 have been provided.

71

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

72

CMA will WITHHOLD votes from directors who:

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

77

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (1940 Act), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the

1

outstanding shares of a Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

                                                       Distributions of the Advisor from 2001 to April, 2002.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

11. The section entitled "Trustee Positions," a subsection of "Management of the Funds," is revised to read:

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Columbia Fund Complex or any person controlling, controlled by or under common control with any such entity.

12. The section entitled "PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES" is revised in its entirety as follows:

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

11

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement. If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at (NAV) to the following individuals, whether currently employed or retired: Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of Financial Service Firms (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds

NAV eligibility for Class A purchase also applies to the families of the parties listed above and their beneficial accounts. Family members include: spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

12

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at (NAV) will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who (i) purchased Galaxy Fund Prime A shares at net asset value and received Class A shares in exchange for those shares

during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after Columbia Management Services, Inc. received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation ("ROA"). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent ("LOI"). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

13

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and (ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

14

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

9. The second paragraph of the section entitled "Other Disclosures," a subsection of "Disclosure of Portfolio Information," is revised in its entirety to read:

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1986. Each Fund is an open-end, diversified management investment company representing the entire interest in a separate series of the Trust. The Income Fund commenced investment operations on March 5, 1986. The Intermediate Bond Fund commenced investment operations on December 5, 1978. The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

The Intermediate Bond Fund offers four classes of shares - Class A, B, C and Z shares. Prior to July 31, 2000, the Fund had a single class of shares. On July 14, 2000, the outstanding shares of the Fund were converted into Class S shares, and on July 31, 2000, the Fund commenced offering Class A shares. On February 1, 2002, the Fund commenced offering Class B and C shares. On July 29, 2002, the Fund's Class S shares were redesignated as Class Z shares. Prior to September 12, 2002, the Fund invested all of its assets in the SR&F Intermediate Bond Portfolio as part of a master fund/feeder fund structure. Effective February 1, 2002, the Fund changed its name from "Stein Roe Intermediate Bond Fund" to "Liberty Intermediate Bond Fund." Effective October 13, 2003, the Fund changed its name from "Liberty Intermediate Bond Fund" to its current name.

The Income Fund offers four classes of shares - Class A, B, C and Z shares. Prior to August 1, 2000, the Fund had a single class of shares. On that date, the outstanding shares of the Fund were converted into Class S shares, and the Fund commenced offering Class A shares. On July 15, 2002, the Fund added Class B and C shares, redesignated its Class S shares as Class Z shares, and changed its name from "Stein Roe Income Fund" to "Liberty Income Fund" and the word "Bond" was deleted from the name of its Class A shares. Prior to July 15, 2002, the Fund invested all of its assets in the SR&F Income Portfolio as part of a master fund/feeder fund structure. Effective October 13, 2003, the Fund changed its name from "Liberty Income Fund" to its current name.

Effective October 13, 2003, the Trust changed its name from "Liberty-Stein Roe Funds Income Trust" to its current name. It is expected that, subject to shareholder approval of the election of all current Trustees, each Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expeted to be reorganized.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (the "1940 Act"), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or
(2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

As fundamental investment policies, each Fund may not:

(1) invest in a security if, as a result of such investment, more than 25% of its total assets (taken at market value at the time of such investment) would be invested in the securities of issuers in any particular industry, except that this restriction does not apply to (i) repurchase agreements, or (ii) securities of issuers in the financial services industry, and except that all or substantially all of the assets of the Fund may be invested in another registered investment company having the same investment objective and substantially similar investment policies as the Fund;

(2) invest in a security if, with respect to 75% of its assets, as a result of such investment, more than 5% of its total assets (taken at market value at the time of such investment) would be invested in the securities of any one issuer, except that this restriction does not apply to U.S. Government Securities or repurchase agreements for such securities and except that all or substantially all of the assets of the Fund may be invested in another registered investment company having the same investment objective and substantially similar investment policies as the Fund;

c

(3) invest in a security if, as a result of such investment, it would hold more than 10% (taken at the time of such investment) of the outstanding voting securities of any one issuer, except that all or substantially all of the assets of the Fund may be invested in another registered investment company having the same investment objective and substantially similar investment policies as the Fund;

(4) purchase or sell real estate (although it may purchase securities secured by real estate or interests therein, or securities issued by companies which invest in real estate, or interests therein);

(5) purchase or sell commodities or commodities contracts or oil, gas or mineral programs, except that it may enter into (i) futures and options on futures and (ii) forward contracts;

(6) make loans, although it may (a) lend portfolio securities and participate in an interfund lending program with certain other Funds provided that no such loan may be made if, as a result, the aggregate of such loans would exceed 33 1/3% of the value of its total assets (taken at market value at the time of such loans); (b) purchase money market instruments and enter into repurchase agreements; and (c) acquire publicly distributed or privately placed debt securities;

(7) borrow except from banks, other affiliated funds and other entities to the extent permitted by the 1940 Act;

(8) act as an underwriter of securities, except insofar as it may be deemed to be an "underwriter" for purposes of the Securities Act of 1933 on disposition of securities acquired subject to legal or contractual restrictions on resale, except that all or substantially all of the assets of the Fund may be invested in another registered investment company having the same investment objective and substantially similar investment policies as the Fund; or

(9) issue any senior security except to the extent permitted under the 1940 Act.

The Funds' Trustees have approved, subject to shareholder approval at a shareholder meeting expected to be held in 2005, the replacement of the Funds' current fundamental investment restrictions with the following standardized fundamental investment restrictions:

PROPOSED FUNDAMENTAL RESTRICTIONS.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or
(b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies;

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein;

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts;

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations

d

thereunder and any applicable exemptive relief;

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) the Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies, which may be changed without a shareholder vote, each Fund may not:

(A) invest for the purpose of exercising control or management;

(B) purchase more than 3% of the stock of another investment company or purchase stock of other investment companies equal to more than 5% of its total assets (valued at time of purchase) in the case of any one other investment company and 10% of such assets (valued at time of purchase) in the case of all other investment companies in the aggregate; any such purchases are to be made in the open market where no profit to a sponsor or dealer results from the purchase, other than the customary broker's commission, except for securities acquired as part of a merger, consolidation or acquisition of assets;(1)

(C) purchase portfolio securities from, or sell portfolio securities to, any of the officers and directors or trustees of the Trust or of its investment adviser;

(D) purchase shares of other open-end investment companies, except in connection with a merger, consolidation, acquisition, or reorganization;

(E) invest more than 5% of its net assets (valued at time of investment) in warrants, nor more than 2% of its net assets in warrants which are not listed on the New York or American Stock Exchange;

(F) purchase a put or call option if the aggregate premiums paid for all put and call options exceed 20% of its net assets (less the amount by which any such positions are in-the-money), excluding put and call options purchased as closing transactions;

(G) write an option on a security unless the option is issued by the Options Clearing Corporation, an exchange, or similar entity;

(H) invest in limited partnerships in real estate unless they are readily marketable;

(I) sell securities short unless (i) it owns or has the right to obtain securities equivalent in kind and amount to those sold short at no added cost or (ii) the securities sold are "when issued" or "when distributed" securities which it expects to receive in a recapitalization, reorganization, or other exchange for securities it contemporaneously owns or has the right to obtain and provided that transactions in options, futures, and options on futures are not treated as short sales;

(J) invest more than 15% of its total assets (taken at market value at the time of a particular investment) in restricted securities, other than securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933;

(K) invest more than 15% of its net assets (taken at market value at the time of a particular investment) in illiquid securities, including repurchase agreements maturing in more than seven days;

(L) purchase securities on margin, except for use of short-term credit necessary for clearance of purchases and sales of portfolio securities, but it may make margin deposits in connection with transactions in options, futures, and options on futures.


(1) The Funds have been informed that the staff of the Securities and Exchange Commission takes the position that the issuers of certain CMOs and certain other collateralized assets are investment companies and that subsidiaries of foreign banks may be investment companies for purposes of Section 12(d)(1) of the 1940 Act, which limits the ability of one investment company to invest in another investment company. Accordingly, the Funds intend to operate within the applicable limitations under Section 12(d)(1)(A) of the 1940 Act.

e


Total assets and net assets are determined at current value for purposes of compliancde with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

COMPENSATION

As of each Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

12B-1 PLAN AND CDSC

Each Fund offers four classes of shares - Class A, Class B, Class C and Class Z. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for each Fund's Class A, B and C shares. Under the Plan, each Fund pays CFD monthly a service fee at an annual rate of 0.25% of the average daily net assets attributed to Class A, B and C shares. The Intermediate Bond Fund also pays CFD monthly a distribution fee at an annual rate of 0.10% of the Fund's average daily net assets attributed to Class A shares and 0.75% of the Fund's average daily net assets attributed to its Class B and C shares. At this time, CFD has voluntarily agreed to waive the Class A share distribution fee and a portion of the Class C share distribution fee so that it does not exceed 0.60% annually. This arrangement may be modified or terminated by CFD at any time. The Income Fund also pays CFD monthly a distribution fee at an annual rate of 0.75% of the Fund's average daily net assets attributed to its Class B and Class C shares. At this time, CFD has voluntarily agreed to waive the Class C share distribution fee so that it does not exceed 0.60% annually. This arrangement may be modified or terminated by CFD at any time. CFD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of CFD's expenses, CFD may realize a profit from the fees. The Plan authorizes any other payments by the Funds to CFD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirectly financing of distribution of a Fund's shares.

q


The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Funds and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares, and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses for the Funds.

No CDSC will be imposed on shares derived from reinvestment of distributions on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions, and finally of other shares held by the shareholder for the longest time.

A certain number of years, depending on the program you purchased your shares under, after the end of the month in which a Class B share is purchased, such shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are either not subject to the distribution fee or subject to a lesser distribution fee. See a Prospectus for a description of the different programs.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I (formerly named Liberty Funds Trust I), Columbia Funds Trust II (formerly named Liberty Funds Trust II), Columbia Funds Trust III (formerly named Liberty Funds Trust III), Columbia Funds Trust IV (formerly named Liberty Funds Trust IV), Columbia Funds Trust V (formerly named Liberty Funds Trust V), Columbia Funds Trust VI (formerly named Liberty Funds Trust VI), Columbia Funds Trust VII (formerly named Liberty Funds Trust VII), Columbia Funds Trust VIII (formerly named Liberty-Stein Roe Funds Income Trust), Columbia Funds Trust IX (formerly named Liberty-Stein Roe Funds Municipal Trust) and Columbia Funds Trust XI (formerly named Liberty-Stein Roe Funds Investment Trust) (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and


4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

2

ZERO COUPON SECURITIES (ZEROS)

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities

3

of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

4

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

5

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each

6

Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

8

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

9

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options

10

written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in
(i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian..

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of

11

the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the

12

independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

13

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option

14

and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

15

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts

16

are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

17

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on

18

demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor

19

evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

20

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in

21

the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, the American Jobs Creation Act of 2004 (the "2004 Act"), provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

22

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31,2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

23

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CFS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the

24

amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the 2004 Act, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

25

The 2004 Act modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the 2004 Act, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

26

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS The Advisor provides administrative and management services to the Funds. On April 1, 2003, Fleet Investment Advisors Inc., Stein Roe & Farnham Incorporated, Colonial Management Associates, Inc. and Newport Pacific Management, Inc. (NPMI), merged into Columbia Management Advisors, Inc. Each of the four merging companies was a registered investment advisor and advised various Funds in the Fund Complex. The Advisor, located at 100 Federal Street, Boston, Massachusetts 02110, is a direct wholly owned subsidiary of Columbia Management Group, Inc. (Columbia), which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to April 1, 2004, Columbia was an indirect wholly owned subsidiary of FleetBoston Financial Corporation, a U.S. financial holding company. Effective April 1, 2004, FleetBoston Financial Corporation was acquired by Bank of America Corporation. The Advisor has been an investment advisor since 1969.

In addition, immediately prior to the mergers described above and also on April 1, 2003, Newport Fund Management, Inc. (NFMI), a subsidiary of NPMI and a registered investment advisor that advised several Funds in the Fund Complex, merged into NPMI. As a result of NPMI's merger into the Advisor, the Advisor is now the Advisor to the Funds previously advised by NFMI.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 101 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The Advisor and/or its affiliate, Colonial Advisory Services, Inc. (CASI), has rendered investment advisory services to investment company, institutional and other clients since 1931. The Advisor currently serves as investment advisor or administrator for 133 open-end and 10 closed-end management investment company portfolios. Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing

35

and mailing any Prospectuses sent to shareholders. Columbia Funds Distributor, Inc. (formerly named Liberty Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund (formerly named Liberty Money Market Fund) and Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund), the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CFS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CFS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement.

SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. The Advisor's affiliate, CASI, advises other institutional, corporate, fiduciary and individual clients for which CASI performs various services. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

36

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

37

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing

38

broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CFD is the principal underwriter of the Trust's shares. CFD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CFS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CFS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CFS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CFS or generally by 6 months' notice by CFS to the Fund. The agreement limits the liability of CFS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CFS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CFS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CFS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CFS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CFS.

CODE OF ETHICS

The Funds, the Advisor, and CFD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Management, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Management and its affiliates. The Fund's policies prohibit Columbia Management and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings

40

with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF
   TYPE OF FUND        INFORMATION PROVIDED     DISCLOSURE      DATE OF WEB POSTING
   ------------      -----------------------   ------------   ----------------------
   Equity Funds      Full portfolio holdings      Monthly     30 calendar days after
                           information.                             month-end.

Fixed Income Funds   Full portfolio holdings     Quarterly    60 calendar days after
                           information.                             quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Funds Distributor, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Management or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Management and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers(R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Management's trading systems (InvestorTool, Inc. and Thomson Financial).These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may

41

experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund), Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Newport Europe Fund (formerly named Liberty Newport Europe Fund) and Columbia Newport Asia Pacific Fund (formerly named Liberty Newport Asia Pacific Fund))

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET
FUND))

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value

42

method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CFS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CFD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CFD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CFD may from time to time reallow additional amounts to all or certain FSFs. CFD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CFD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CFS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CFS, provided the new FSF has a sales agreement with CFD.

Shares credited to an account are transferable upon written instructions in good order to CFS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CFS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CFD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CFD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CFD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

43

Subject to applicable rules, CFD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CFD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CFD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CFD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CFD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CFD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Funds Services, Inc. (formerly named Liberty Funds Services, Inc.) (CFS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CFD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CFD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CFD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Management prototype plans offered through CFD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CFD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CFS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CFS. The close out fee applies to plans opened after September 1,1996. The fee is in addition to any applicable

47

CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Management IRA Rollover account in any Fund distributed by CFD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CFS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CFS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Class A, Class B and Class T shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A, B and T shares can be effected by combining a current purchase of Class A, Class B or Class T shares with prior purchases of other funds distributed by CFD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all funds' held by the shareholder.

CFD must be promptly notified of each purchase which entitles a shareholder to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CFS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement. Upon request, a Statement of Intent may be backdated to reflect purchases within 90 days.

During the term of a Statement, CFS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement. The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. As a part of this adjustment, the FSF shall return to CFD the excess commission previously paid during the thirteen-month period.

If the amount of the Statement is not purchased, the shareholder shall remit to CFD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CFS will redeem that number of escrowed Class A, E or T shares to equal such

48

difference. The additional amount of FSF discount from the applicable offering price shall be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CFS at 1-800-345-6611.

REINSTATEMENT PRIVILEGE. Subject to the Fund's fund policy on trading of fund shares, an investor who has redeemed Class A, B, C or T shares (other than shares of the Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Global Equity Fund (formerly named Liberty Newport Global Equity Fund) and Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) that were redeemed within 30 days of their acquisition by exchange from another fund) may, upon request, reinstate within one year a portion or all of the proceeds of such sale in shares of Class A of any Fund at the NAV next determined after CFS receives a written reinstatement request and payment. Investors who desire to exercise this privilege should contact their FSF or CFS. Shareholders may exercise this privilege an unlimited amount of times. Exercise of this privilege does not alter the federal income tax treatment of any capital gains realized on the prior sale of Fund shares, but to the extent any such shares were sold at a loss, some or all of the loss may be disallowed for tax purposes. Consult your tax advisor.

PRIVILEGES OF COLUMBIA EMPLOYEES OR FINANCIAL SERVICE FIRMS (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS). Class A shares of certain Funds may be sold at NAV to the following individuals whether currently employed or retired: Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CFD and companies affiliated with the Advisor; registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CFD; and such persons' families and their beneficial accounts.

PRIVILEGES OF COLUMBIA ACORN FUNDS (FORMERLY NAMED LIBERTY ACORN FUNDS) SHAREHOLDERS. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29,2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any fund distributed by CFD, may purchase Class A shares of any fund distributed by CFD at NAV in those cases where a Columbia Fund Class Z share is not available. Qualifying shareholders will not be subject to any Class A initial sales charge or CDSC; however, they will be subject to the annual Rule 12b-1 service fee.

FEE-BASED COMPENSATION ARRANGEMENTS. Class A, Class E and Class T shares (Class T shares can only be purchased by the shareholders of Liberty Newport Tiger Fund who already own Class T shares) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into agreements with CFD pursuant to which the Funds are included as investment options in programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

WAIVER OF INITIAL SALES CHARGES (CLASS A AND CLASS T SHARES)

Class A share initial sales charges (but not contingent deferred sales charges) are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995; and

- Shareholders who (i) purchased Galaxy Fund Prime A Shares at net asset value and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

Class T share sales charges are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995;

- Shareholders who (i) purchased Galaxy Fund Retail A Shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and

- Boston 1784 Fund shareholders on the date the Funds were reorganized into Galaxy Funds.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions within one year following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the

49

occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account occurring within one year after the death. If shares are not redeemed within one year of the death, they will remain subject to the applicable CDSC, when redeemed from the transferee's account. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CFS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met; this requirement does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "Investor Services - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring within one year after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by the Advisor.

6. Qualified Retirement Plans. CDSCs may be waived on redemptions required to make distributions from qualified retirement plans following normal retirement (as stated in the Plan document). CDSCs also will be waived on SWP redemptions made to make required minimum distributions from qualified retirement plans that have invested in Funds distributed by CFD for at least two years. CDSC is also waived for participant loans.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CFS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CFS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CFS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CFS and may charge for this service.

50

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1 % to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CFS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CFS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS)
(Available only on the Class A and Z shares of certain Funds)

Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CFS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the

51

order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1 % of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CFD to broker-dealer organizations which have entered into agreements with CFD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds.

52

Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CFD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in

53

the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CFD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CFD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

54

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CFS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CFS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CFS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CFS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CFS may require customary additional documentation. Prospectuses of the other Funds are available from the CFD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CFS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

55

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

As described under the caption "Organization and History", the Fund will not hold annual shareholders' meetings. The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose, which meeting shall be held upon written request of the holders of not less than 10% of the outstanding shares of the Trust. Upon written request by the holders of 1% of the outstanding shares of the Trust stating that such shareholders of the Trust, for the purpose of obtaining the signatures necessary to demand a shareholders' meeting to consider removal of a Trustee, request information regarding the Trust's shareholders, the Trust will provide appropriate materials (at the expense of the requesting shareholders). Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although

57

addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1,2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

58

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

59

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1,2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic

60

rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(2) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(3) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

Cma shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST


(2) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(3) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, Inc.

62

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

63

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

64

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters-ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

65

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

66

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

67

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

68

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

CMA will WITHHOLD votes from directors who:

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE.

V. VOTING PROCEDURES

73

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

74

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1986. The Fund is an open-end, diversified management investment company representing the entire interest in a separate series of the Trust. The Intermediate Bond Fund commenced investment operations on December 5, 1978. The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of the Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

The Intermediate Bond Fund offers four other classes of shares (in addition to Class R shares) - Class A, B, C and Z shares. Prior to July 31, 2000, the Fund had a single class of shares. On July 14, 2000, the outstanding shares of the Fund were converted into Class S shares, and on July 31, 2000, the Fund commenced offering Class A shares. On February 1, 2002, the Fund commenced offering Class B and C shares. On July 29, 2002, the Fund's Class S shares were redesignated as Class Z shares. Prior to September 12, 2002, the Fund invested all of its assets in the SR&F Intermediate Bond Portfolio as part of a master fund/feeder fund structure. Effective February 1, 2002, the Fund changed its name from "Stein Roe Intermediate Bond Fund" to "Liberty Intermediate Bond Fund." Effective October 13, 2003, the Fund changed its name from "Liberty Intermediate Bond Fund" to its current name. The Prospectuses and Statement of Additional Information relating to Class A, B, C and Z shares of the Fund are available upon request from CMD.

Effective October 13, 2003, the Trust changed its name from "Liberty-Stein Roe Funds Income Trust" to its current name.

It is expected that, subject to shareholder approval of the election of all current Trustees, the Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (the "1940 Act"), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or
(2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or
(b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies;

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein;

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell

c

options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts;

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) the Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies, which may be changed without a shareholder vote, the Fund may not:

(A) invest for the purpose of exercising control or management;

(B) purchase more than 3% of the stock of another investment company or purchase stock of other investment companies equal to more than 5% of its total assets (valued at time of purchase) in the case of any one other investment company and 10% of such assets (valued at time of purchase) in the case of all other investment companies in the aggregate; any such purchases are to be made in the open market where no profit to a sponsor or dealer results from the purchase, other than the customary broker's commission, except for securities acquired as part of a merger, consolidation or acquisition of assets;(1)

(C) purchase portfolio securities from, or sell portfolio securities to, any of the officers and directors or trustees of the Trust or of its investment adviser;

(D) purchase shares of other open-end investment companies, except in connection with a merger, consolidation, acquisition, or reorganization;

(E) invest more than 5% of its net assets (valued at time of investment) in warrants, nor more than 2% of its net assets in warrants which are not listed on the New York or American Stock Exchange;

(F) purchase a put or call option if the aggregate premiums paid for all put and call options exceed 20% of its net assets (less the amount by which any such positions are in-the-money), excluding put and call options purchased as closing transactions;

(G) write an option on a security unless the option is issued by the Options Clearing Corporation, an exchange, or similar entity;

(H) invest in limited partnerships in real estate unless they are readily marketable;


(1) The Fund has been informed that the staff of the Securities and Exchange Commission takes the position that the issuers of certain CMOs and certain other collateralized assets are investment companies and that subsidiaries of foreign banks may be investment companies for purposes of Section 12(d)(1) of the 1940 Act, which limits the ability of one investment company to invest in another investment company. Accordingly, the Fund intends to operate within the applicable limitations under Section
12(d)(1)(A)of the 1940 Act.

d

(I) sell securities short unless (i) it owns or has the right to obtain securities equivalent in kind and amount to those sold short at no added cost or (ii) the securities sold are "when issued" or "when distributed" securities which it expects to receive in a recapitalization, reorganization, or other exchange for securities it contemporaneously owns or has the right to obtain and provided that transactions in options, futures, and options on futures are not treated as short sales;

(J) invest more than 15% of its total assets (taken at market value at the time of a particular investment) in restricted securities, other than securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933;

(K) invest more than 15% of its net assets (taken at market value at the time of a particular investment) in illiquid securities, including repurchase agreements maturing in more than seven days;

(L) purchase securities on margin, except for use of short-term credit necessary for clearance of purchases and sales of portfolio securities, but it may make margin deposits in connection with transactions in options, futures, and options on futures.

Total assets and net assets are determined at current value for purposes of compliancde with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

FUND CHARGES AND EXPENSES

Effective February 9, 2005, under the Fund's management contract, the Fund pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of:

Average Daily Net Assets                               Rate

CMS acts as transfer agent, dividend disbursing agent and shareholders' servicing agent for the Fund. Its address is P.O. Box 8081, Boston Massachusetts 02266-8081. Effective November 1, 2005, the Fund entered into a Transfer, Dividend Disbursing and Shareholders' Servicing Agent Agreement with CMS, under which CMS will provide transfer agency, dividend disbursing and shareholders' servicing agency services to the Fund.

COMPENSATION

As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN AND CDSC

The Fund offers four other classes of shares (in addition to Class R shares) - Class A, Class B, Class C and Class Z. The information set forth in this SAI addresses the offering of Class R shares by the Fund. Each share class has its own expense structure. The Fund may in the future offer other classes of shares. The Trustees have approved a Distribution Plan (Plan) pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, Class R shares of the Fund may pay CMD monthly a distribution fee at an annual rate of up to 0.50% of the average daily net assets attributed to Class R shares. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution fees are payable regardless of CMD's expenses, CMD may realize a profit from the fees. The

l

Plan will authorize any other payments by the Fund to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirectly financing of distribution of the Fund's shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of the Fund's assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Fund and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares, and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class R shares will be offered at net asset value.

CUSTODIAN OF THE FUNDS

State Street Bank and Trust Company, located at 2 Avenue De Lafayette, Boston, MA 02111-2900, is the custodian for the Fund. The custodian is responsible for safeguarding the Fund's cash and securities, receiving and delivering securities and collecting the Fund's interest and dividends.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information ("SAI") to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

1

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES ("ZEROS")

2

The Fund may invest in Zeros, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zeros include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS ("STEPS")

The Fund may invest in debt securities, known as Steps, which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND ("PIK") SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities

3

of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of

4

variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial

5

condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

6

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through

7

dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed

8

securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options

9

written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER ("OTC") OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases,

10

refer to your Fund's Prospectus) of the Fund's net assets would be invested in
(i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

11

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

12

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures

13

contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

14

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

15

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future

16

date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign

17

currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature

18

will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933 Act"). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

19

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

20

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities

21

or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in
(a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation provides that for taxable years of a regulated investment company beginning after October 22, 2004,100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders in the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax

22

advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

23

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

24

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that, in general, would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a

25

period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceeds the annual gift-tax exemption, which in 2006 is $12,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $12,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

26

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $24,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $2 million in 2006, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (46% for gifts made in 2006) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required

27

each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS Columbia Management Advisors, LLC ("Columbia Advisors" or "CMA" or the "Advisor"), located at 100 Federal Street, Boston, Massachusetts 02110 is the Advisor to the Funds. The Advisor provides administrative and management services to the Funds.

On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005 Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

Trustee Positions

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

Approving the Investment Advisory Contract

In determining to approve the most recent annual extension of a Fund's management agreement, the Trustees met over the course of the year with the relevant investment advisory personnel from the Advisor and considered information provided by the Advisor relating to the education, experience and number of investment professionals and other personnel providing services under that agreement. See "Managing the Fund" in each Fund's Prospectus and "Trustees and Officers" in this SAI. The Trustees also took into account the time and attention devoted by senior management to the Funds and the other funds in the Fund Complex. The Trustees evaluated the level of skill required to manage the Funds and concluded that the human resources devoted by the Advisor to the Funds were appropriate to fulfill effectively the Advisor's duties under the agreement. The Trustees also considered the business reputation of the Advisor and its financial resources, and concluded that the Advisor would be able to meet any reasonably foreseeable obligations under the agreement.

The Trustees received information concerning the investment philosophy and investment process applied by the Advisor in managing the Funds. See "Principal Investment Strategies" and "Principal Investment Risks" in the Funds' Prospectuses. In this connection, the Trustees considered the Advisor's in-house research capabilities as well as other resources available to the Advisor's personnel, including research services available to the Advisor as a result of securities transactions effected for the Funds and other investment advisory clients. The Trustees concluded that the Advisor's investment process, research capabilities and philosophy were well suited to each Fund, given each Fund's investment goal(s) and policies.

The Trustees considered the scope of the services provided by the Advisor to the Funds under the agreement relative to services provided by third parties to other mutual funds. See "Fund Charges and Expenses" and "Management of the Funds
- The Management Agreement". The Trustees concluded that the scope of the Advisor's services to the Funds was consistent with the Funds' operational requirements, including, in addition to its investment goal, compliance with each Fund's investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services provided by the Advisor to the Funds. The Trustees evaluated the Advisor's record with respect to regulatory compliance and compliance with the investment policies of each Fund. The Trustees also evaluated the procedures of the Advisor designed to fulfill the Advisor's fiduciary duty to the Funds with respect to possible conflicts of interest, including the Advisor's code of ethics (regulating the personal trading of its officers and employees) (see "Management of the Funds -Code of Ethics"), the procedures by which the Advisor allocates trades among its various investment advisory clients and the record of the Advisor in these matters. The Trustees also received information concerning standards of the Advisor with respect to the execution of portfolio transactions. See "Management of the Funds
- Portfolio Transactions."

The Trustees considered the Advisor's management of non-advisory services provided by persons other than the Advisor by reference, among other things, to each Fund's total expenses and the reputation of each Fund's other service providers. See "Your Expenses" in each Fund's Prospectus(es). The Trustees also considered information provided by third parties relating to each Fund's investment performance relative to its performance benchmark(s), relative to other similar funds managed by the Advisor and relative to funds managed similarly by other advisors. The Trustees reviewed performance over various periods, including each Fund's one, five and ten year calendar year periods and/or the life of the Fund, as applicable (See "Performance History" in the Fund's Prospectuses), as well as factors identified by the Advisor as contributing to each Fund's performance. See each Fund's most recent annual and semi-annual reports. The Trustees concluded that the scope and quality of the Advisor's services was sufficient to merit reapproval of the agreement for another year.

In reaching that conclusion, the Trustees also gave substantial consideration to the fees payable under the agreement. The Trustees reviewed information concerning fees paid to investment advisors of similarly-managed funds. The Trustees also considered the fees of the Funds as a percentage of assets at different asset levels and possible economies of scale to the Advisor. The Trustees evaluated the Advisor's profitability with respect to the Funds, concluding that such profitability appeared to be generally consistent with levels of profitability that had been determined by courts to be "not excessive." For these purposes, the Trustees took into account not only the actual dollar amount of fees paid by the Funds directly to the Advisor, but also so-called "fallout benefits" to the Advisor such as reputational value derived from serving as investment Advisor to the Funds and the research services available to the Advisor by reason of brokerage commissions generated by each Fund's turnover. In evaluating the Funds' advisory fees, the Trustees also took into account the complexity of investment management for the Funds relative to other types of funds. Based on challenges associated with less readily available market information about foreign issuers and smaller capitalization companies, limited liquidity of certain securities, and the specialization required for focused funds, the Trustees concluded that generally greater research intensity and trading acumen is required for equity funds, and for international or global funds, as compared to funds investing, respectively, in debt obligations or in U.S.

36

issuers. Similarly, the Trustees concluded that, generally, small capitalization equity funds and focused funds including state specific municipal funds, require greater intensity of research and trading acumen than larger capitalization or more diversified funds. See "The Fund" in each Fund's Prospectus.

Based on the foregoing, the Trustees concluded that the fees to be paid the Advisor under the advisory agreement were fair and reasonable, given the scope and quality of the services rendered by the Advisor.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 83 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $75,000, an attendance fee of $10,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $20,000; the chair of the Advisory Fees and Expenses Committee receives a supplemental retainer at an annual rate of $15,000; and the chair of each other committee receives a supplemental retainer at the annual rate of $10,000. Members of each committee receive $2,500 for each committee meeting held in person and $1,000 for each telephonic meeting. The chair of the Audit Committee receives an additional $500 per meeting supplement. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust ("Declaration") of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (the "Agreement"), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. CMD pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

37

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement ("Outsourcing Agreement"), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

38

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions

39

pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate

40

solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the 1940 Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the

41

fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF
   TYPE OF FUND        INFORMATION PROVIDED     DISCLOSURE      DATE OF WEB POSTING

Equity Funds         Full portfolio holdings   Monthly        30 calendar days after
                     information.                             month-end.

Fixed Income Funds   Full portfolio holdings   Quarterly      60 calendar days after
                     information.                             quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, CMD at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings

42

information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund and Columbia Newport Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET
FUND))

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio

43

under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include: realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

44

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts; (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for

47

sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares; (ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

48

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares. Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor for funds held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at NAV will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at NAV and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after CMS received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

50

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

51

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under
Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN. The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

52

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the National Securities Clearing Corporation (NSCC).

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS)
(Available only on the Class A and Z shares of certain Funds)

Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to

53

ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Longer than six years                 None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

55

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

SALES CHARGES

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends ("include Funds") will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends ("exclude Funds") will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

57

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND
RATINGS STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

59

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

60

Plus(+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest. Ca bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

61

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1,2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

62

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

63

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

64

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

65

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

66

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters - ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

67

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

68

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

69

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

70

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of THE reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C.PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

74

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

Effective November 1, 2005, the following language replaced the language currently in the section of the Statement of Additional Information entitled FUNDAMENTAL INVESTMENT POLICIES:

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (1940 Act), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that:
(a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

(Born 1965)                          Treasurer                     Advisor since January, 2001.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

16. The section entitled "Trustee Positions," a subsection of "Management of the Funds," is revised to read:

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

11

17. The second paragraph of the section entitled "Other Disclosures," a subsection of "Disclosure of Portfolio Information," is revised in its entirety to read:

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

18. The section entitled "PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES" is revised in its entirety as follows:

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

12

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at (NAV) to the following individuals, whether currently employed or retired: Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of Financial Service Firms (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds

NAV eligibility for Class A purchase also applies to the families of the parties listed above and their beneficial accounts. Family members include:
spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

13

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at (NAV) will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at net asset value and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after Columbia Management Services, Inc. received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

14

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1978. The Fund, an open-end, diversified management investment company representing the entire interest in a separate series of the Trust. The Fund commenced investment operations on August 23, 1991. The Fund is the successor by reorganization to the Liberty Financial Utilities Fund. The reorganization occurred on March 27, 1995. All references to the Fund as of a time prior to such date shall be deemed to refer to the Liberty Financial Utilities Fund. On February 26, 1999, the Fund and the Liberty Funds Trust VIII (formerly the LFC Utilities Trust Portfolio) terminated their master/feeder fund structure. Effective April 1, 1999, the Trust changed its name from "Colonial Trust III" to "Liberty Funds Trust III." The Trust changed its name to its current name on October 13, 2003. Effective July 14, 2000, the Fund changed its name from "Colonial Global Utilities Fund" to "Liberty Newport Global Utilities Fund." Effective February 12, 2001, the Fund changed its name to "Liberty Newport Global Equity Fund". Effective October 13, 2003 the Fund changed its name from "Liberty Newport Global Equity Fund" to its current name.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of the Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

It is expected that, subject to shareholder approval of the election of all current Trustees, the Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

FUNDAMENTAL INVESTMENT POLICIES

b


The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

As fundamental investment policies, the Fund may not:

1. Borrow from banks, other affiliated funds and other entities except to the extent permitted by applicable law and, provided that the Fund's borrowings shall not exceed 33 1/3% of the value of its total assets (including the amount borrowed) less liabilities (other than borrowings) or such other percentage permitted by law;

2. Purchase any security on margin, except that the Fund may obtain such short-term credit as may be necessary for the clearance of purchases and sales of securities (this restriction does not apply to securities purchased on a when-issued basis or to margin deposits in connection with futures and options transactions);

3. Issue senior securities except as provided in paragraph 1 above and to the extent permitted by the 1940 Act;

4. Underwrite securities issued by other persons, except insofar as the Fund may technically be deemed an underwriter under the Securities Act of 1933, as amended (the "1933 Act") in selling a security and except that the Fund may invest all or substantially all of its assets in another registered investment company having substantially the same investment objective as the Fund;

5. Make loans except (a) through lending of securities, (b) through the purchase of debt instruments or similar evidences of indebtedness typically sold privately to financial institutions, (c) through an interfund lending program with other affiliated registered open-end investment companies provided that no such loan may be made if, as a result, the aggregate of such loans would exceed 33 1/3% of the value of its total assets (taken at market value at the time of such loans) and (d) through repurchase agreements;

6. Purchase the securities of any one issuer (except securities issued or guaranteed by the U.S. government and its agencies or instrumentalities, as to which there are no percentage limits or restrictions) if immediately after and as a result of such purchase (a) more than 5% of the value of its assets would be invested in that issuer, or (b) the Fund would hold more than 10% of the outstanding voting securities of that issuer and except that the Fund may invest all or substantially all of its assets in another registered investment company having substantially the same investment objective as the Fund;

7. Purchase or sell real estate or interests in real estate limited partnerships (other than securities secured by real estate or interests therein), interests in oil, gas or mineral leases, commodities or commodity contracts in the ordinary course of business (the Fund reserves the freedom of action to hold and to sell real estate acquired as a result of the ownership of securities and to enter into futures and options transactions in accordance with its investment policies); or

8. Invest more than 25% of its total assets in the securities of issuers whose principal business activities are in the same industry (excluding obligations of the U.S. government and repurchase agreements collateralized by obligations of the U.S. government), except that the Fund may invest without limit (but may not invest less than 25% of its total assets) in the securities of companies in the public utilities industry and except that the Fund may invest all or substantially all of its assets in another registered investment company having substantially the same investment objective as the Fund.

The Fund's Trustees have approved, subject to shareholder approval at a shareholder meeting expected to be held in 2005, the replacement of the Fund's current fundamental investment restrictions with the following standardized fundamental investment restrictions:

PROPOSED FUNDAMENTAL RESTRICTIONS.

The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or
(b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies;

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein;

c

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts;

4.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

7.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies, which may be changed without a shareholder vote, the Fund may not:

1. Invest in illiquid securities, including repurchase agreements maturing in more than seven days but excluding securities which may be resold pursuant to Rule 144A under the Securities Act of 1933, if, as a result thereof, more than 15% of the net assets (taken at market value at the time of each investment of the Fund, as the case may be) would be invested in such securities and except that the Fund may invest all or substantially all of its assets in another registered investment company having substantially the same investment objective as the Fund;

2. Invest in companies for the purpose of exercising control or management except that the Fund may invest all or substantially all its assets in another registered investment company having substantially the same investment restrictions as the Fund;

3. Invest in the voting securities of a public utility company if, as a result, it would own 5% or more of the outstanding voting securities of more than one public utility company;

4. Make investments in the securities of other investment companies except that the Fund may invest all or substantially all its assets in another registered investment company having substantially the same investment restrictions as the Fund;

5. Mortgage, pledge, hypothecate or in any manner transfer, as security for indebtedness, any securities owned by the Fund except (a) as may be necessary in connection with borrowings mentioned in (1) under Fundamental Investment Policies, and (b) the Fund may enter into futures and options transactions; or

6. Invest more than 5% of its total assets in puts, calls, straddles, spreads, or any combination thereof (except that the Fund may enter into transactions in options, futures and options on futures).

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectus under "Financial Highlights." The Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment goal. Portfolio investments may be sold for a variety of reasons, such as a more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Fund to realize capital gains which, if realized and distributed by the Fund, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Fund.

During the twelve month period ended October 31, 2003, the Fund experienced a higher rate of portfolio turnover than during the previous fiscal year. This was due largely to the repositioning of the Fund during the fourth quarter. With an improving investment environment in the second quarter and with improving global economic activity, the manager reduced the Fund's percentage in US holdings and increased its non-US holdings.

During the five month period ended March 31, 2004, the Fund experienced a lower rate of portfolio turnover than during the previous fiscal year. This was due largely to the lower reallocation activity between countries than the previous year which, therefore, required fewer purchases and sales within the portfolio.

FUND CHARGES AND EXPENSES

Under the Fund's management agreement, the Fund pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of 0.40% for the first billion and 0.35% over $1 billion. The Fund also pays the Advisor a monthly administrative fee of 0.25%.

The Advisor is responsible for providing pricing and bookkeeping services to the Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Corporation (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement.

Under its pricing and bookkeeping agreement with the Fund, the Advisor receives from the Fund a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

- An annual flat fee of $10,000, paid monthly; and

- In any month that the Fund has average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

The Fund reimburses the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

Effective November 1, 2003, the Fund pays a shareholders' servicing and transfer agency fee to CFS as follows:

An annual open account fee of $28 per open account, plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CFS.

Prior to November 1, 2003, the Fund paid a shareholders' servicing and transfer agency fee to CFS as follows:

- An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus

- A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of the Fund for such month; plus

- The Fund's allocated share of CFS' out-of-pocket expenses, including fees payable to DST Systems, Inc. (DST) under a remote services agreement with DST.

COMPENSATION

i

As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

The Fund offers three classes of shares - Class A, Class B and Class C. The Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for Class A, Class B and Class C shares. Under the Plan, the Fund pays CFD monthly a service fee at an annual rate of 0.25% of the average daily net assets attributed to Class A, Class B and Class C shares. The Fund also pays CFD monthly a distribution fee at an annual rate of 0.75% of the average daily net assets attributed to Class B and Class C shares. CFD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CFD's expenses, CFD may realize a profit from the fees. The Plan authorizes any other payments by the Fund to CFD and its affiliates (including the Administrator) to the extent that such payments might be construed to be indirectly financing the distribution of Fund shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of Fund assets resulting in a more advantageous expense ratio and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

k


Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. The CDSCs are described in the Prospectus.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

After a certain number of years, depending on the program you purchased your shares under, after the end of the month in which a Class B share is purchased, such shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value which are not subject to the distribution fee. See the Prospectus for a description of the different programs.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I (formerly named Liberty Funds Trust I), Columbia Funds Trust II (formerly named Liberty Funds Trust II), Columbia Funds Trust III (formerly named Liberty Funds Trust III), Columbia Funds Trust IV (formerly named Liberty Funds Trust IV), Columbia Funds Trust V (formerly named Liberty Funds Trust V), Columbia Funds Trust VI (formerly named Liberty Funds Trust VI), Columbia Funds Trust VII (formerly named Liberty Funds Trust VII), Columbia Funds Trust VIII (formerly named Liberty-Stein Roe Funds Income Trust), Columbia Funds Trust IX (formerly named Liberty-Stein Roe Funds Municipal Trust) and Columbia Funds Trust XI (formerly named Liberty-Stein Roe Funds Investment Trust) (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic

1

developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

2

ZERO COUPON SECURITIES (ZEROS)

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities

of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

5

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each

6

Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

7

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

8

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

9

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

10

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian..

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type

11

of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

12

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a

13

clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if

14

the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the

15

dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

16

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is

17

generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but

18

may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer.

19

The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of

20

the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to

21

its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, the American Jobs Creation Act of 2004 (the "2004 Act"), provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

22

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of

23

the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CFS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

24

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the 2004 Act, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United

25

States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

The 2004 Act modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the 2004 Act, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

26

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

27

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS The Advisor provides administrative and management services to the Funds. On April 1, 2003, Fleet Investment Advisors Inc., Stein Roe & Farnham Incorporated, Colonial Management Associates, Inc. and Newport Pacific Management, Inc. (NPMI), merged into Columbia Management Advisors, Inc. Each of the four merging companies was a registered investment advisor and advised various Funds in the Fund Complex. The Advisor, located at 100 Federal Street, Boston, Massachusetts 02110, is a direct wholly owned subsidiary of Columbia Management Group, Inc. (Columbia), which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to April 1, 2004, Columbia was an indirect wholly owned subsidiary of FleetBoston Financial Corporation, a U.S. financial holding company. Effective April 1, 2004, FleetBoston Financial Corporation was acquired by Bank of America Corporation. The Advisor has been an investment advisor since 1969.

In addition, immediately prior to the mergers described above and also on April 1, 2003, Newport Fund Management, Inc. (NFMI), a subsidiary of NPMI and a registered investment advisor that advised several Funds in the Fund Complex, merged into NPMI. As a result of NPMI's merger into the Advisor, the Advisor is now the Advisor to the Funds previously advised by NFMI.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 101 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The Advisor and/or its affiliate, Colonial Advisory Services, Inc. (CASI), has rendered investment advisory services to investment company, institutional and other clients since 1931. The Advisor currently serves as investment advisor or administrator for 133 open-end and 10 closed-end management investment company portfolios. Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. Columbia Funds Distributor, Inc. (formerly named Liberty Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

35

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund (formerly named Liberty Money Market Fund) and Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund), the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto. The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CFS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CFS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. The Advisor's affiliate, CASI, advises other institutional, corporate, fiduciary and individual clients for which CASI performs various services. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

36

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts. The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to

37

the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

38

CFD is the principal underwriter of the Trust's shares. CFD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CFS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CFS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CFS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CFS or generally by 6 months' notice by CFS to the Fund. The agreement limits the liability of CFS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CFS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CFS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CFS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CFS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CFS.

CODE OF ETHICS

The Funds, the Advisor, and CFD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the

39

potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Management, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Management and its affiliates. The Fund's policies prohibit Columbia Management and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Funds Distributor, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Management or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

40

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Management and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers(R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Management's trading systems (InvestorTool, Inc. and Thomson Financial).These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund), Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Newport Europe Fund (formerly named Liberty Newport Europe Fund) and Columbia Newport Asia Pacific Fund (formerly named Liberty Newport Asia Pacific Fund))

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

41

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET FUND)

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CFS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CFD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CFD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CFD may from time to time reallow additional amounts to all or certain FSFs. CFD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CFD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

42

CFS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CFS, provided the new FSF has a sales agreement with CFD.

Shares credited to an account are transferable upon written instructions in good order to CFS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CFS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CFD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CFD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CFD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CFD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CFD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CFD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CFD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CFD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CFD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Funds Services, Inc. (formerly named Liberty Funds Services, Inc.) (CFS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

45

CFD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CFD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CFD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Management prototype plans offered through CFD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CFD.

46

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CFS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CFS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Management IRA Rollover account in any Fund distributed by CFD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CFS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CFS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Class A, Class B and Class T shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A, B and T shares can be effected by combining a current purchase of Class A, Class B or Class T shares with prior purchases of other funds distributed by CFD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all funds' held by the shareholder.

CFD must be promptly notified of each purchase which entitles a shareholder to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CFS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement. Upon request, a Statement of Intent may be backdated to reflect purchases within 90 days.

During the term of a Statement, CFS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement. The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. As a part of this adjustment, the FSF shall return to CFD the excess commission previously paid during the thirteen-month period.

If the amount of the Statement is not purchased, the shareholder shall remit to CFD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CFS will redeem that number of escrowed Class A, E or T shares to equal such difference. The additional amount of FSF discount from the applicable offering price shall be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CFS at 1-800-345-6611.

47

REINSTATEMENT PRIVILEGE. Subject to the Fund's fund policy on trading of fund shares, an investor who has redeemed Class A, B, C or T shares (other than shares of the Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Global Equity Fund (formerly named Liberty Newport Global Equity Fund) and Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) that were redeemed within 30 days of their acquisition by exchange from another fund) may, upon request, reinstate within one year a portion or all of the proceeds of such sale in shares of Class A of any Fund at the NAV next determined after CFS receives a written reinstatement request and payment. Investors who desire to exercise this privilege should contact their FSF or CFS. Shareholders may exercise this privilege an unlimited amount of times. Exercise of this privilege does not alter the federal income tax treatment of any capital gains realized on the prior sale of Fund shares, but to the extent any such shares were sold at a loss, some or all of the loss may be disallowed for tax purposes. Consult your tax advisor.

PRIVILEGES OF COLUMBIA EMPLOYEES OR FINANCIAL SERVICE FIRMS (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS). Class A shares of certain Funds may be sold at NAV to the following individuals whether currently employed or retired: Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CFD and companies affiliated with the Advisor; registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CFD; and such persons' families and their beneficial accounts.

PRIVILEGES OF COLUMBIA ACORN FUNDS (FORMERLY NAMED LIBERTY ACORN FUNDS) SHAREHOLDERS. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any fund distributed by CFD, may purchase Class A shares of any fund distributed by CFD at NAV in those cases where a Columbia Fund Class Z share is not available. Qualifying shareholders will not be subject to any Class A initial sales charge or CDSC; however, they will be subject to the annual Rule 12b-1 service fee.

FEE-BASED COMPENSATION ARRANGEMENTS. Class A, Class E and Class T shares (Class T shares can only be purchased by the shareholders of Liberty Newport Tiger Fund who already own Class T shares) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into agreements with CFD pursuant to which the Funds are included as investment options in programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

WAIVER OF INITIAL SALES CHARGES (CLASS A AND CLASS T SHARES)

Class A share initial sales charges (but not contingent deferred sales charges) are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995; and

- Shareholders who (i) purchased Galaxy Fund Prime A Shares at net asset value and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

Class T share sales charges are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995;

- Shareholders who (i) purchased Galaxy Fund Retail A Shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and

- Boston 1784 Fund shareholders on the date the Funds were reorganized into Galaxy Funds.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions within one year following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account occurring within one year after the death. If shares are not redeemed within one year of the death, they will remain subject to the applicable CDSC, when redeemed from the transferee's account. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CFS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met; this requirement does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "Investor Services - Systematic Withdrawal Plan."

48

3. Disability. CDSCs may be waived on redemptions occurring within one year after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by the Advisor.

6. Qualified Retirement Plans. CDSCs may be waived on redemptions required to make distributions from qualified retirement plans following normal retirement (as stated in the Plan document). CDSCs also will be waived on SWP redemptions made to make required minimum distributions from qualified retirement plans that have invested in Funds distributed by CFD for at least two years. CDSC is also waived for participant loans.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CFS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CFS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CFS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CFS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

49

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CFS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CFS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS) (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CFS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred

50

sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CFD to broker-dealer organizations which have entered into agreements with CFD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------

Through second year                  4.00
Through third year                   3.00
Through fourth year                  3.00
Through fifth year                   2.00
Through sixth year                   1.00
Longer than six years                None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CFD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CFD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CFD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CFS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CFS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CFS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CFS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CFS may require customary additional documentation. Prospectuses of the other Funds are available from the CFD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CFS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

53

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

As described under the caption "Organization and History", the Fund will not hold annual shareholders' meetings. The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose, which meeting shall be held upon written request of the holders of not less than 10% of the outstanding shares of the Trust. Upon written request by the holders of 1% of the outstanding shares of the Trust stating that such shareholders of the Trust, for the purpose of obtaining the signatures necessary to demand a shareholders' meeting to consider removal of a Trustee, request information regarding the Trust's shareholders, the Trust will provide appropriate materials (at the expense of the requesting shareholders). Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

55

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

56

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

57

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated `AAA'. Because bonds rated in the `AAA' and `AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated `F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

58

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY. CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, Inc.

60

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

61

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

62

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

63

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

64

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

65

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

66

8. Investment Company Matters

Election of Directors:

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

- Are interested directors and the full board serves as the audit or nominating committee or the company does not have one of these committees.

Proxy Contests:

CMA will vote on a CASE-BY-CASE basis proposals for proxy contests, considering the following factors:

- Past performance relative to its peers

- Market in which fund invests

- Measures taken by the board to address the pertinent issues (e.g., closed-end fund share market value discount to NAV)

- Past shareholder activism, board activity and votes on related proposals

- Strategy of the incumbents versus the dissidents

- Independence of incumbent directors; director nominees

- Experience and skills of director nominees

- Governance profile of the company

- Evidence of management entrenchment

CMA will vote conversion proposals on a CASE-BY-CASE basis, considering the following factors:

- Past performance as a closed-end fund

- Market in which the fund invests

- Measures taken by the board to address the discount

- Past shareholder activism, board activity, and votes on related proposals.

Investment Advisory Agreements:

CMA will vote investment advisory agreements on a CASE-BY-CASE basis, considering the following factors:

- Proposed and current fee schedules

- Fund category/investment objective

- Performance benchmarks

- Share price performance as compared with peers

- Resulting fees relative to peers

- Assignments (where the adviser undergoes a change of control)

Approving New Classes or Series of Shares:

CMA will vote FOR the establishment of new classes or series of shares.

Preferred Stock Proposals:

CMA will vote on a CASE-BY-CASE basis proposals for the authorization for or increase in the preferred shares, considering the following factors:

- Stated specific financing purpose

- Possible dilution for common shares

- Whether the shares can be used for antitakover purposes

67

Policies Addressed by the Investment Company Act of 1940 ("1940 Act"):

CMA will vote proposals regarding adoption or changes of policies addressed by the 1940 Act on a CASE-BY-CASE basis, considering the following factors:

- Potential competitiveness

- Regulatory developments

- Current and potential returns

- Current and potential risk

CMA generally will vote FOR these amendments as long as the proposed changes do not fundamentally alter the investment focus of the fund and do comply with current SEC interpretations.

Changing a Fundamental Restriction to a Non-fundamental Restriction:

CMA will vote on a CASE-BY-CASE basis proposals to change a fundamental restriction to a nonfundamental restriction, considering the following factors:

- Fund's target investments

- Reasons given by the fund for the change

- Projected impact of the change on the portfolio

Change Fundamental Investment Objective to Non-fundamental:

CMA will vote AGAINST proposals to change a fund's investment objective from fundamental to non-fundamental unless management acknowledges meaningful limitations upon its future requested ability to change the objective

Name Change Proposals:

CMA will vote on a CASE-BY-CASE basis proposals to change a fund's name, considering the following factors:

- Political/economic changes in the target market

- Consolidation in the target market

Change in Fund's Subclassification:

CMA will vote on a CASE-BY-CASE basis proposals to change a fund's subclassification, considering the following factors:

- Potential competitiveness

- Current and potential returns

- Risk of concentration

- Consolidation in target industry

Disposition of Assets/Termination/Liquidation:

CMA will vote on a CASE-BY-CASE basis these proposals, considering the following factors:

- Strategies employed to salvage the company

- Past performance of the fund

- Terms of the liquidation

Changes to the Charter Document:

CMA will vote on a CASE-BY-CASE basis proposals to change the charter document, considering the following factors:

- The degree of change implied by the proposal

- The efficiencies that could result

- The state of incorporation; net effect on shareholder rights

- Regulatory standards and implications

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

69

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The

70

recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

1

The Investment Company Act of 1940, as amended (1940 Act), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Portfolio's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

                                                              and Distributions of the Advisor from 2001 to
                                                              April, 2002.

Each of the Trust's Trustees and officers hold comparable positions with certain other funds of which the Advisor or its affiliates is the investment advisor or distributor and, in the case of certain of the officers, with certain affiliates of the Advisor.

The Trustees and officers serve terms of indefinite duration. Each Fund held a shareholders' meeting in 2005, and will hold a shareholders' meeting at least once every five years thereafter to elect Trustees.

14. The section entitled "Trustee Positions," a subsection of "Management of the Funds," is revised to read:

As of December 31, 2005, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

15. The second paragraph of the section entitled "Other Disclosures," a subsection of "Disclosure of Portfolio Information," is revised in its entirety to read:

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on

11

the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

16. The section entitled "PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES" is revised in its entirety as follows:

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in

12

sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

1. Employees, brokers and various relationships that are allowed to buy at NAV. Class A shares of certain Funds may be sold at (NAV) to the following individuals, whether currently employed or retired: Employees of Bank of America Corporation (and its predecessors), its affiliates and subsidiaries; Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CMD, or its successors and companies affiliated with the Advisor; Registered representatives and employees of Financial Service Firms (including their affiliates) that are parties to dealer agreements or other sales arrangements with CMD; Nations Funds' Trustees, Directors and employees of its investment sub-advisers; Broker/Dealers if purchases are in accordance with the internal policies and procedures of the employing broker/dealer and made for their own investment purposes; employees or partners of any contractual service provider to the funds

NAV eligibility for Class A purchase also applies to the families of the parties listed above and their beneficial accounts. Family members include: spouse, parent, stepparent, legal guardian, child, stepchild, father-in-law and mother-in-law.

Individuals receiving a distribution from a Bank of America trust, fiduciary, custodial or other similar account may use the proceeds of that distribution to buy Class A shares without paying a front-end sales charge, as long as the proceeds are invested in the funds within 90 days of the date of distribution.

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at (NAV) will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at net asset value and received Class A

13

shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after Columbia Management Services, Inc. received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1986. Each Fund is an open-end, diversified management investment company that represents the entire interest in a separate series of the Trust. Each Fund is the successor to a separate series of The Galaxy Fund II, a Massachusetts business trust organized on February 22, 1990. On November 25, 2002 and December 9, 2002, the series of The Galaxy Fund II to which the Funds succeeded (the "Predecessor Funds") were reorganized as separate series of the Trust. Class Z shares of the Funds were issued in exchange for existing shares of the Predecessor Funds. The Funds currently offer Class A, B, C and Z shares, and may in the future offer other classes of shares.

The Galaxy II Large Company Index Fund, the predecessor to the Large Company Index Fund, commenced operations on October 1, 1990; the Galaxy II Small Company Index Fund, the predecessor to the Small Company Index Fund, commenced operations on October 1, 1990; and the Galaxy II U.S. Treasury Index Fund, the predecessor to the U.S. Treasury Index Fund, commenced operations on June 4, 1991.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

Effective October 13, 2003, the Trust changed its name from "Liberty Funds Trust V" to its current name. Effective October 13, 2003, the Large Company Index Fund changed its name from "Liberty Large Company Index Fund" to its current name. Effective October 13, 2003, the Small Company Index Fund changed its name from "Liberty Small Company Index Fund" to its current name. Effective October 13, 2003, the U.S. Treasury Index Fund changed its name from "Liberty U.S. Treasury Index Fund" to its current name.

It is expected that, subject to shareholder approval of the election of all current Trustees, the U.S. Treasury Index Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

INVESTMENT GOAL AND POLICIES

The Prospectuses describe each Fund's investment goal, investment strategies and risks. Part 1 of this SAI includes additional information concerning, among other things, the investment policies of the Funds. Part 2 contains additional information about the following securities and investment techniques that may be utilized by each Fund (unless otherwise noted):

Common Stock, Preferred Stock and Warrants Money Market Instruments
Securities Loans
Repurchase Agreements
Futures Contracts and Related Options (the Large Company Index and Small Company Index Funds only)
Temporary Cash Balances

b


Except as indicated below under "Fundamental and Non-Fundamental Investment Policies," the Funds' investment policies are not fundamental, and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

FUNDAMENTAL INVESTMENT POLICIES

In addition to each Fund's investment goal as stated in its Prospectuses, the following investment limitations are matters of fundamental policy and may not be changed with respect to a Fund without the affirmative vote of the holders of a majority of its outstanding shares. A "vote of the holders of a majority of the outstanding shares" of a particular Fund means the affirmative vote of the holders of the lesser of (a) more than 50% of the outstanding shares of such Fund, or (b) 67% or more of the shares of such Fund present at a meeting if more than 50% of the outstanding shares of such Fund are represented at the meeting in person or by proxy.

Each Fund may not:

1. Underwrite any issue of securities except to the extent that the sale of portfolio securities in accordance with the Fund's investment objective, policies and limitations may be deemed to be underwriting.

2. Purchase or sell real estate or real estate limited partnership interests, or invest in oil, gas or mineral leases, or mineral exploration or development programs, except that the Fund may invest in securities secured by real estate, mortgages or interests therein and may purchase securities issued by companies that invest or deal in any of the above.

3. Make short sales of securities or maintain a short position.

4. Purchase securities on margin, except that a Fund may obtain any short-term credits necessary for the clearance of purchases and sales of securities. For purposes of this restriction, the deposit or payment of initial or variation margin in connection with futures contracts or related options will not be deemed to be a purchase of securities on margin by the Fund.

5. Invest in commodities, except that the Large Company Index Fund and the Small Company Index Fund may invest in stock index futures.

6. Invest in companies for the purpose of exercising control or management.

7. Purchase the securities of any issuer if as a result more than 5% of the value of the Fund's total assets would be invested in the securities of such issuer, except that (a) this 5% limitation does not apply to U.S. Government securities and (b) up to 25% of the value of the Fund's total assets may be invested without regard to this 5% limitation.

8. Borrow money or issue senior securities except that the Fund may borrow from banks for temporary or emergency purposes, and not for leveraging, and then in amounts not in excess of 33-1/3% of the value of the Fund's total assets at the time of such borrowing; or mortgage, pledge or hypothecate any assets except in connection with any bank borrowing and in amounts not in excess of the lesser of the dollar amounts borrowed or 33-1/3% of the value of the Fund's total assets at the time of such borrowing. Whenever borrowings are outstanding, a Fund will not make any additional investments (including roll-overs). For purposes of this restriction, collateral arrangements with respect to (a) the purchase and sale of options on stock indexes and (b) initial and variation margin for futures contracts will not be deemed to be issuances of senior securities or to be pledges of a Fund's assets.

9. Purchase any securities that would cause 25% or more of the value of the Fund's total assets at the time of purchase to be invested in the securities of issuers conducting their principal business activities in the same industry, provided that there shall be no limit on the purchase of U.S Government securities.

10. Make loans, except that the Fund may purchase or hold debt obligations, lend portfolio securities and enter into repurchase agreements, as described herein and in the prospectuses.

11. Purchase securities of other investment companies except as they may be acquired in connection with a merger, consolidation, acquisition, reorganization or offer of exchange and except as permitted under the Investment Company Act of 1940, as amended (the "1940 Act"). Purchases made in connection with this restriction may subject shareholders to duplicate fees and expenses.

12. Purchase more than 10% of the voting securities of any one issuer, more than 10% of the securities of any class of any one issuer or more than 10% of the outstanding debt securities of any one issuer; provided that this limitation shall not apply to investments in U.S. Government securities.

13. Invest more than 5% of the value of the Fund's net assets in securities which may be illiquid because of legal or contractual restrictions on resale or securities for which there are no readily available market quotations. For purposes of this limitation, repurchase agreements with maturities greater than seven days shall be considered illiquid securities.

The U.S Treasury Index Fund's Trustees have approved, subject to shareholder approval at a shareholder meeting expected to be held in 2005, the replacement of the Fund's current fundamental investment restrictions with the following standardized fundamental investment restrictions:

c

PROPOSED FUNDAMENTAL RESTRICTIONS.

The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies;

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein;

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts;

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) the Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

NON-FUNDAMENTAL INVESTMENT POLICIES

The Large Company Index Fund and the Small Company Index Fund may not engage in futures activities for other than bona fide hedging purposes if the aggregate initial margin deposits on its non-hedging futures contracts and premiums paid on its related options exceed 5% of the fair market value of the Fund's total assets, after taking into account unrealized profits and unrealized losses on futures contracts it has entered into.

Each of the Funds will set aside with its custodian, or with a designated subcustodian, cash or liquid securities at least equal to the underlying commodity value of each long position the Fund assumes in commodity futures contracts or will take other actions consistent with regulatory requirements to avoid leverage.

Each Fund will adhere to the following conditions whenever its portfolio securities are loaned: (a) the loans will not exceed 33- 1/3% of the Fund's total assets taken at value; (b) the Fund must receive cash or equivalent securities from the borrower as collateral at least equal to 100% of the current market value of the loaned securities plus any interest and dividends accrued thereon; (c) the borrower must increase such collateral whenever the market value of the securities plus any accrued interest or dividends rises above the level of such collateral; (d) the Fund must be able to terminate the loan at any time; (e) the Fund must receive reasonable interest on the loan, as well as any dividends, interest or other distributions on the loaned securities, and any increase in market value; (f) the Fund may pay only reasonable custodian fees in connection with the loan; and (g) voting rights on the loaned securities may pass to the borrower, provided, however, that if a material event adversely affecting the investment occurs, the Board of Trustees must terminate the loan and regain the right to vote the securities.

d

Each of the Funds will not enter into repurchase agreements that would cause more than 5% of their respective net assets to be invested in illiquid securities.

Except as stated otherwise and except with respect to Investment Limitation No. 8, if a percentage limitation is satisfied at the time of investment, a later increase in such percentage resulting from a change in the value of a Fund's portfolio securities generally will not constitute a violation of the limitation. If the value of a Fund's holdings of illiquid securities at any time exceeds the percentage limitation applicable at the time of acquisition due to subsequent fluctuations in value or other reasons, the Board of Trustees will consider what actions, if any, are appropriate to maintain adequate liquidity. With respect to borrowings, if a Fund's asset coverage at any time falls below that required by the 1940 Act, the Fund will reduce the amount of its borrowings in the manner required by the 1940 Act to the extent necessary to satisfy the asset coverage requirement.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

Each Fund may follow non-fundamental operating policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectuses and this Statement of Additional Information, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act.

THE INDEXING APPROACH

The Funds are not managed in a traditional sense, that is, by making discretionary judgments based on analysis of economic, financial and market conditions. Instead, the Funds seek to match the investment performance of their respective market segments, as represented by their respective indexes, through the use of sophisticated computer models to determine which stocks or bonds should be purchased or sold, while keeping transaction and administrative costs to a minimum. In using sophisticated computer models to select securities, a Fund will only purchase a security that is included in its respective index at the time of such purchase. A Fund may, however, temporarily continue to hold a security that has been deleted from its respective index pending the rebalancing of the Fund's portfolio. A list of securities included, as of the date of this Statement of Additional Information, in each of the Standard & Poor's 500 Composite Stock Price Index ("S&P 500"), the Standard & Poor's SmallCap 600 Stock Price Index ("S&P SmallCap 600 Index"), and the U.S. Treasury component ("U.S. Treasury Index") of the Citigroup Bond U.S. Treasury Index is available free of charge by calling the Advisor at 1-800-426-3750, or by writing to the Advisor, c/o Columbia Funds Services, Inc. ("CFS"), P.O. Box 8081, Boston, MA 02266-8081.

While there can be no guarantee that each Fund's investment results will precisely match the results of its corresponding index, the Advisor believes that, before deduction of operating expenses, there will be a very high correlation between the returns generated by the Funds and their respective indexes. Each Fund will attempt to achieve a correlation between the performance of its portfolio and that of its respective index of at least 0.95 before deduction of operating expenses. A correlation of 1.00 would indicate perfect correlation, which would be achieved when a Fund's net asset value, including the value of its dividend and capital gains distributions, increases or decreases in exact proportion to changes in its respective index. Each Fund's ability to correlate its performance with its respective index, however, may be affected by, among other things, changes in securities markets, the manner in which Standard & Poor's or Citigroup calculates their respective indexes, and the timing of purchases and redemptions. The Advisor monitors the correlation of the performance of the Funds in relation to their indexes under the supervision of the Board of Trustees. In the unlikely event that a high correlation is not achieved, the Board of Trustees will take appropriate steps based on the reasons for the lower than expected correlation.

The Advisor believes that the indexing approach should involve less turnover, and thus lower brokerage costs, transfer taxes and operating expenses, than in more traditionally managed funds, although there is no assurance that this will be the case. Ordinarily, a Fund will buy or sell securities only to reflect changes in an index (including mergers or changes in the composition of an index) or to accommodate cash flows into and out of the Fund. The costs and other expenses incurred in securities transactions, apart from any difference between the investment results of a Fund and that of its respective index, may cause the return of a Fund to be lower than the return of its respective index. The Funds may invest in less than all of the securities included in their respective indexes, which may result in a return that does not match that of the indexes, after taking expenses into account.

LARGE COMPANY INDEX FUND

The Large Company Index Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets plus any borrowings for investment purposes) in the common stocks of large companies included in the S&P
500. This 80%

e


policy may be changed by the Board of Trustees without shareholder approval, although shareholders will be given at least 60 days' prior written notice of any such change.

The S&P 500 is composed of 500 common stocks, most of which are listed on the New York Stock Exchange (the "NYSE"). S&P chooses the stocks for the S&P 500 on a statistical basis. As of December 31, 2004, the stocks in the S&P 500 had an average market capitalization of approximately $22.3 billion and accounted for approximately 74% of the total market value of all U.S. common stocks. The Advisor believes that the S&P 500 is an appropriate benchmark for the Fund because it is diversified, it is familiar to many investors and it is widely accepted as a reference for common stock investments.

SMALL COMPANY INDEX FUND

The Small Company Index Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets, plus any borrowings for investment purposes) in the common stocks of small companies included in the S&P SmallCap 600 Index. This 80% policy may be changed by the Board of Trustees without shareholder approval, although shareholders will be given at least 60 days' prior written notice of any such change.

The S&P SmallCap 600 Index is comprised of 600 U.S. common stocks with small market capitalizations. Like the S&P 500, the weighting of stocks in the S&P SmallCap 600 Index is based on each stock's relative total market capitalization. As of December 31, 2004, stocks in the S&P SmallCap 600 Index accounted for about 3.45% of the total market value of all publicly traded U.S. common stocks. The average capitalization of stocks included in the S&P SmallCap 600 Index as of December 31, 2004 was approximately $870 million, although the capitalization of some companies included in the S&P SmallCap 600 Index is significantly higher.

When utilized, the portfolio optimization program is expected to provide an effective method of substantially duplicating the dividend income and capital gains produced by the S&P SmallCap 600 Index. Since the Fund does not hold every stock in the S&P SmallCap 600 Index when utilizing portfolio optimization, it is not expected to track the S&P SmallCap 600 Index with the same degree of accuracy as when it holds all 600 stocks in the Index, although the Fund will seek a correlation of at least 0.95, before deduction of operating expenses.

U.S. TREASURY INDEX FUND

The U.S. Treasury Index Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets plus any borrowings for investment purposes) in U.S. Treasury securities included in the U.S. Treasury Index. This 80% policy may be changed by the Board of Trustees without shareholder approval, although shareholders will be given at least 60 days' prior written notice of any such change.

The U.S. Treasury Index is composed of all U.S. Treasury notes and bonds with remaining maturities of at least one year and outstanding principal of at least $25 million. Securities in the Index are weighted by market value, that is, the price per bond or note multiplied by the number of bonds or notes outstanding. Citigroup updates the roster of securities represented in the U.S. Treasury Index monthly, adding new notes and bonds issued in the past month and removing those notes and bonds that no longer meet the index's criteria. The following table further describes the U.S. Treasury Index Fund as of December 31, 2004:

      Cash equivalent reserve              1%

f


The Fund will not hold all of the issues in its index because of the costs involved. Instead, each security will be considered for inclusion in the Fund based on its contribution to the total market value, average coupon rate and average weighted maturity of the Fund and its similarity to these financial characteristics of the Fund's index.

The Fund is authorized to engage in other types of securities transactions as described elsewhere in this Statement of Additional Information. Because the Fund expects to generate income generally exempt from state and local income taxes, it will engage in such investment practices only when deemed by the Advisor to be in the best interests of the Fund's shareholders.

PORTFOLIO TURNOVER

The Advisor believes that the indexing approach should involve less turnover, and thus lower brokerage costs, transfer taxes and operating expenses, than in more traditionally managed funds, although there is no assurance that this will be the case. For more information, see the section above entitled, "The Indexing Approach."

Portfolio turnover is included in the Prospectuses under "Financial Highlights." Each Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment goal. Portfolio investments may be sold for a variety of reasons, such as a more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Funds to realize capital gains which, if realized and distributed by the Funds, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Funds.

FUND CHARGES AND EXPENSES

For the services provided and expenses assumed with respect to the Funds, the Advisor is entitled to receive advisory fees, computed daily and paid monthly, at the annual rate of 0.10% of the average daily net assets of each Fund. For the period from July 1, 2003 through October 31, 2003, the Advisor waived 0.06% of the Large Company Index Fund's advisory fee. For the fiscal year ended March 31, 2004, the effective annual advisory fee rate for the Large Company Index Fund was 0.08%.

Under the US Treasury Index Fund's administration agreement, the Fund pays the Administrator a monthly fee at the annual rate of 0.30% of the average daily net assets of the Fund. The Administrator pays all operating expenses of the Fund with the exception of brokerage fees and expenses, taxes, interest, fees and expenses of Trustees who are not officers, directors or employees of the Administrator or its affiliates, and any extraordinary non-recurring expenses that may arise, including, but not limited to, litigation expenses.

Effective November 1, 2004, under the Columbia Large Company Index Fund's and Columbia Small Company Index Fund's administration agreements, each of these Funds pays the Administrator a fee at the annual rate of 0.10% of the average daily net assets of the Fund. Prior to November 1, 2004, the Columbia Large Company Index Fund and Columbia Small Company Index Fund paid fees under their administration agreements at the rates set forth in the immediately preceding paragraph.

The Administrator is responsible for providing pricing and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (outsourcing agreement), the Administrator has delegated those functions to State Street Corporation (State Street). The Administrator pays fees to State Street under the outsourcing agreement.

Prior to July 1, 2002, Fleet National Bank ("FNB"), an affiliate of the Advisor, located at 100 Federal Street, Boston, MA 02110, served as the administrator and fund accountant of the Predecessor Funds and was entitled to receive administration and fund accounting fees at the aggregate annual rate of 0.30% of the average daily net assets of each of the Predecessor Funds. Prior to July 1, 2002, PFPC, Inc. ("PFPC") (formerly known as First Data Investor Services Group, Inc.), located at 4400 Computer Drive, Westborough, Massachusetts 01581-5108, served as sub-administrator of the Predecessor Funds and, prior to July 22, 2002, served as transfer and dividend disbursing agent for the Predecessor Funds. PFPC is an indirect majority-owned subsidiary of PNC Bank Corp. During the last three fiscal years, no administration fees were waived by FNB.

* For the Large Company Index Fund, the brokerage commissions paid in the fiscal year ended March 31, 2003 were higher than the brokerage commissions paid in the prior fiscal year due to an increase in portfolio turnover. The Fund's portfolio turnover reflected changes in companies included in its target index, the S&P 500.

** Rounds to less than 0.

*** Rounds to less than 1.

U.S. Government securities are generally purchased from underwriters or dealers, although certain newly issued U.S. Government securities may be purchased directly from the issuing agency or instrumentality. No brokerage commissions are typically paid on purchases and sales of U.S. Government securities.

COMPENSATION

As of the Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, SHAREHOLDER SERVICING PLAN, CDSCS AND CONVERSION OF SHARES

The Funds offer four classes of shares: Class A, Class B, Class C and Class Z. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan (Plan) pursuant to Rule 12b-1 under the Act. Under the Plan, the Funds pay CFD monthly a service fee at an annual rate of 0.25% of each Fund's average daily net assets attributed to Class A, B and C shares. The Funds also pay CFD monthly a distribution fee at an annual rate of 0.75% of each Fund's average daily net assets attributed to Class B and Class C shares. The Distributor has voluntarily agreed to waive a portion of the 12b-1 fees of the U.S. Treasury Index Class C shares so that these fees do not exceed 0.85% annually of the average daily net assets attributable to Class C shares. CFD may use the entire amount of such fees to defray the cost of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CFD's expenses, CFD may realize a profit from the fees.

The Plan authorizes any other payments by the Funds to CFD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of Fund shares. The Trustees believe the Plan could be a significant factor in the growth and retention of the Funds' assets resulting in more advantageous expense ratios and increased investment flexibility which could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses.

No CDSC will be imposed on shares derived from reinvestment of distributions or amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

A certain number of years, depending on the program you purchased your shares under, after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

NOTES TO FINANCIAL STATEMENTS
March 31, 2005 Columbia Index Funds

NOTE 1. ORGANIZATION

The Columbia Fund Trust V (the "Trust") is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. Information presented in these financial statements pertains to the following diversified portfolios (individually referred to as a "Fund", collectively referred to as the "Funds"):

Columbia Large Company Index Fund

Columbia Small Company Index Fund

Columbia U.S. Treasury Index Fund

INVESTMENT GOALS

Each Fund seeks to provide investment results that, before deduction of operating expenses, match the price and yield performance of its index.

FUND SHARES

The Funds may issue an unlimited number of shares. Each Fund offers four classes of shares: Class A, Class B, Class C and Class Z. Each share class has its own sales charge and expense structure.

Class A shares are subject to a front-end sales charge based on the amount of initial investment. Class A shares purchased without an initial sales charge are subject to a 1.00% contingent deferred sales charge ("CDSC") on shares sold within eighteen months on an original purchase of $1 million to $25 million. Class B shares are subject to a maximum CDSC of 5.00% based upon the holding period after purchase. Class B shares will convert to Class A shares in a certain number of years after purchase, depending on the program under which shares were purchased. Class C shares are subject to a 1.00% CDSC on shares sold within one year after purchase. Class Z shares are offered continuously at net asset value. There are certain restrictions on the purchase of Class Z shares, as described in each Fund's prospectus.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements.

SECURITY VALUATION

Equity securities and exchange traded funds are valued at the last sale price on the principal exchange on which they trade, except for securities traded on the NASDAQ, which are valued at the NASDAQ official close price. Unlisted securities or listed securities for which there were no sales during the day are valued at the closing bid price on such exchanges or over-the-counter markets.

Debt securities generally are valued by pricing services approved by the Funds' Board of Trustees, based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes. Debt securities for which quotations are readily available are valued at an over-the-counter or exchange bid quotation.

Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value.

Investments for which market quotations are not readily available, or have quotations which management believes are not appropriate, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

SECURITY TRANSACTIONS

Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.

REPURCHASE AGREEMENTS

Each Fund may engage in repurchase agreement transactions with institutions that the Funds' investment advisor has determined are creditworthy. Each Fund, through its custodian, receives delivery of underlying securities collateralizing a repurchase

35

March 31, 2005 Columbia Index Funds

agreement. Collateral is at least equal, at all times, to the value of the repurchase obligation including interest. A repurchase agreement transaction involves certain risks in the event of default or insolvency of the counterparty. These risks include possible delays or restrictions upon each Fund's ability to dispose of the underlying securities and a possible decline in the value of the underlying securities during the period while the Funds seek to assert their rights.

INCOME RECOGNITION

Interest income is recorded on the accrual basis. Premium and discount are amortized and accreted, respectively, on all debt securities. Corporate actions and dividend income are recorded on the ex-date.

The Funds estimate components of distributions from real estate investment trusts (REITs). Distributions received in excess of income are recorded as a reduction of the cost of the related investments. If the Funds no longer own the applicable securities, any distributions received in excess of income are recorded as realized gains.

DETERMINATION OF CLASS NET ASSET VALUES

Realized and unrealized gains (losses) for each fund are allocated to each class of each Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class. For the Columbia Large Company Index Fund and the Columbia Small Company Index Fund, all income and expenses (other than class-specific expenses, as shown on the Statements of Operations) are allocated to each class of each Fund, based on the relative net assets of each class. For the Columbia U.S. Treasury Index Fund, all income and expenses (other than class-specific expenses, as shown on the Statements of Operations) are allocated to each class of the Fund, based on the settled shares method.

FEDERAL INCOME TAX STATUS

Each Fund intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its taxable income, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, each Fund intends to distribute in each calendar year substantially all of its net investment income, capital gains and certain other amounts, if any, such that each Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

DISTRIBUTIONS TO SHAREHOLDERS

Distributions to shareholders are recorded on ex-date for the Columbia Large Company Index Fund and Columbia Small Company Index Fund. Net realized capital gains, if any, are distributed at least annually. Dividends from net investment income are declared daily and paid monthly for the Columbia U.S. Treasury Index Fund.

NOTE 3. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Funds' capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations.

For the year ended March 31, 2005, permanent book and tax basis differences resulting primarily from differing treatments for REIT adjustments, market discount reclassifications, redemption based payments treated as dividend paid deduction, ROC dividend adjustment and discount premium/amortization on debt securities were identified and reclassified among the components of the Funds' net assets as follows:

                     Undistributed /
                    (Overdistributed)    Accumulated
                      Net Investment    Net Realized     Paid-In

Net investment income and net realized gains (losses), as disclosed on the Statements of Operations, and net assets were not affected by these reclassifications.

* The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales, REIT adjustments and discount accretion/ premium amortization on debt securities.

Unrealized appreciation and depreciation at March 31, 2005, based on cost of investments for federal income tax purposes, was:

                                                                         Net

   Fund                  1,035         --      5,967     1,495

The Funds have adopted a 12b-1 plan (the "Plan"), which requires the payment of a monthly service fee to the Distributor equal to 0.25% annually of the average daily net assets attributable to Class A, Class B and Class C shares. The Plan also requires the payment of a monthly distribution fee to the Distributor equal to 0.75% annually of the average daily net assets attributable to Class B and Class C shares. The Distributor has voluntarily agreed to waive a portion of the 12b-1 fees of the U.S. Treasury Index Class C shares so that these fees do not exceed 0.85% annually of the average daily net assets attributable to Class C shares.

The CDSC and the fees received from the Plan are used principally as repayment to the Distributor for amounts paid by the Distributor to dealers who sold such shares.

SUB-ACCOUNT SERVICES FEE

The Trust may enter into agreements with one or more entities, including affiliates of Columbia, pursuant to which such entities agree to perform certain sub-account and administrative functions ("Sub-Account Services") for a fee of $21.00 per-account with respect to Class Z shares of the Funds held by defined contribution plans. Such entities are compensated by the Funds for the Sub- Account Services. For the year ended March 31, 2005, the Administrator reimbursed sub-account service fees in the amount of $84,032 and $16,051 for Columbia Large Company Index Fund and Columbia U.S. Treasury Index Fund Class Z shares, respectively.

FEES PAID TO OFFICERS AND TRUSTEES

With the exception of one officer, all officers of the Funds are employees of Columbia or its affiliates and receive no compensation from the Funds. Effective August 23, 2004, the Board of Trustees appointed a Chief Compliance Officer to the Funds in accordance with federal securities regulations. Each Fund, along with other affiliated funds, will pay its pro-rata share of the expenses associated with the Office of the Chief Compliance Officer. Each Fund's fee for the Office of the Chief Compliance Officer will not exceed $15,000 per year.

The Funds' Trustees may participate in a deferred compensation plan which may be terminated at any time. Obligations of the plan will be paid solely out of the Funds' assets.

NOTE 7. LINE OF CREDIT

The Funds and other affiliated funds participate in a $350,000,000 committed unsecured revolving line of credit provided by State Street Bank and Trust Company. Borrowings are used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to each participating fund based on its borrowings at a rate per annum equal to the Federal Funds rate plus 0.50%. In addition, a commitment fee of 0.10% per annum is accrued and apportioned among the participating funds based on their pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statements of Operations.

For the year ended March 31, 2005, the Funds did not borrow under this arrangement.

NOTE 8. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES

LEGAL PROCEEDINGS

On February 9, 2005, Columbia and the Distributor (collectively, the "Columbia Group") entered into an Assurance of Discontinuance with the New York Attorney General ("NYAG") (the "NYAG Settlement") and consented to the entry of a cease-and-desist order by the Securities and Exchange Commission ("SEC") (the "SEC Order"). The SEC Order and the NYAG Settlement are referred to collectively as the "Settlements". The Settlements contain substantially the same terms and conditions as outlined in the agreements in principle which Columbia Group entered into with the SEC and NYAG in March 2004.

Under the terms of the SEC Order, the Columbia Group has agreed among other things, to: pay $70 million in disgorgement and $70 million in civil money penalties; cease and desist from violations of the antifraud provisions and certain other provisions of the federal securities laws; maintain certain compliance and ethics oversight structures; retain an independent consultant to review the Columbia Group's applicable supervisory, compliance, control and other policies and procedures; and retain an independent distribution consultant (see below). The Columbia Funds have also undertaken to implement certain governance measures designed to maintain the independence of their boards of trustees. The NYAG Settlement also, among other things, requires Columbia and its affiliates, Banc of America Capital Management, LLC and BACAP Distributors, LLC to reduce certain Columbia Funds, Nations Funds and other mutual funds management fees collectively by $32 million per year for five years, for a projected total of $160 million in management fee reductions.

Pursuant to the procedures set forth in the SEC order, the $140 million in settlement amounts described above will be distributed in accordance with a distribution plan to be developed by an independent distribution consultant, who is acceptable to the SEC staff and the Columbia Funds' independent trustees. The distribution plan must be based on a methodology developed in consultation with the Columbia Group and the Funds' independent trustees and not unacceptable to the staff of the SEC. "At this time, the distribution plan is still under development. As such, any gain to the fund or its shareholders can not currently be determined."

As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the funds.

A copy of the SEC Order is available on the SEC website at http://www.sec.gov. A copy of the NYAG Settlement is available as part of the Bank of America Corporation Form 8-K filing on February 10, 2005.

On January 11, 2005, a putative class action lawsuit was filed in federal district court in Massachusetts against, among others, the Trustees of the Funds and Columbia. The lawsuit alleges that defendants violated common law duties to fund shareholders as well as sections of the Investment Company Act of 1940, by failing to ensure that the Funds and other affiliated funds participated in securities class action settlements for which the funds were eligible. Specifically, plaintiffs allege that defendants failed to submit proof of claims in connection with settlements of securities class action lawsuits filed against companies in which the funds held positions.

In 2004, certain Columbia funds, advisers and affiliated entities were named as defendants in certain purported shareholder class and derivative actions making claims, including claims under the Investment Company and the Investment Advisers Acts of 1940 and state law. The suits allege, inter alia, that the fees and expenses paid by the funds are excessive and that

39

March 31, 2005 Columbia Index Funds

the advisers and their affiliates inappropriately used fund assets to distribute the funds and for other improper purpose. On March 2, 2005, the actions were consolidated in the Massachusetts federal court as In re Columbia Entities Litigation. The plaintiffs are expected to file a consolidated amended complaint in June 2005.

The Funds and the other defendants to these actions, including Columbia and various of its affiliates, certain other mutual funds advised by Columbia and its affiliates, and various directors of such funds, have denied these allegations and are contesting the plaintiffs' claims. These proceedings are ongoing, however, based on currently available information, Columbia believes that these lawsuits are without merit, that the likelihood they will have a material adverse impact on any fund is remote, and that the lawsuits are not likely to materially affect its ability to provide investment management services to its clients, including the Funds.

For the year ended March 31, 2005, Columbia has assumed $45,326, $15,870 and $8,782 for the Columbia Large Company Index Fund, Columbia Small Company Index Fund and Columbia U.S. Treasury Index Fund, respectively, of legal, consulting services and Trustees' fees incurred by the Funds in connection with these matters.

In connection with events described in detail above, various parties have filed suit against certain funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities. More than 300 cases including those filed against entities unaffiliated with the funds, their Boards, FleetBoston Financial Corporation and its affiliated entities and/or Bank of America Corporation and its affiliated entities have been transferred to the Federal District Court in Maryland and consolidated in a multi-district proceeding (the "MDL"). On March 21, 2005 purported class action plaintiffs filed suit in Massachusetts state court alleging that the conduct, including market timing, entitles Class B shareholders in certain Columbia funds to an exemption from contingent deferred sales charges upon early redemption (the "CDSC Lawsuit"). The CDSC Lawsuit has been removed to federal court in Massachusetts and the federal Judicial Panel has conditionally ordered its transfer to the MDL. The MDL is ongoing. Accordingly, an estimate of the financial impact of this litigation on any Fund, if any, can not currently be made.

NOTE 9. PROPOSED REORGANIZATION

On February 10, 2005, the Board of Trustees of the Funds approved a proposal to merge the Columbia Large Company Index Fund into the Nations LargeCap Index Fund. Also on that date, the Board of Trustees approved a proposal to merge the Columbia Small Company Index Fund into the Nations SmallCap Index Fund. The proposals are subject to approval by shareholders of the Funds and the satisfaction of certain other conditions. The mergers, if approved, are expected to be completed in the third quarter of 2005.

                                        includes examining, on a test basis,

                                        disclosures in the financial statements,
                                        assessing the accounting principles used
                                        and significant estimates made by

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I (formerly named Liberty Funds Trust I), Columbia Funds Trust II (formerly named Liberty Funds Trust II), Columbia Funds Trust III (formerly named Liberty Funds Trust III), Columbia Funds Trust IV (formerly named Liberty Funds Trust IV), Columbia Funds Trust V (formerly named Liberty Funds Trust V), Columbia Funds Trust VI (formerly named Liberty Funds Trust VI), Columbia Funds Trust VII (formerly named Liberty Funds Trust VII), Columbia Funds Trust VIII (formerly named Liberty-Stein Roe Funds Income Trust), Columbia Funds Trust IX (formerly named Liberty-Stein Roe Funds Municipal Trust) and Columbia Funds Trust XI (formerly named Liberty-Stein Roe Funds Investment Trust) (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad- based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

2

ZERO COUPON SECURITIES (ZEROS)

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

3

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

4

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so- called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may

5

draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

6

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax- free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

8

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES.

Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

9

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

10

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian.

11

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

12

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv)

13

unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

15

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time.

16

Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are

17

less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax- exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However,

18

in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege.

19

Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed- income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S.

20

Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

21

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, the American Jobs Creation Act of 2004 (the "2004 Act"), provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership
(i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in
(a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent

22

a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage- backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

23

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

24

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CFS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short- term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the 2004 Act, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S.

25

person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

The 2004 Act modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the 2004 Act, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX- MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

26

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is

27

currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS The Advisor provides administrative and management services to the Funds. On April 1, 2003, Fleet Investment Advisors Inc., Stein Roe & Farnham Incorporated, Colonial Management Associates, Inc. and Newport Pacific Management, Inc. (NPMI), merged into Columbia Management Advisors, Inc. Each of the four merging companies was a registered investment advisor and advised various Funds in the Fund Complex. The Advisor, located at 100 Federal Street, Boston, Massachusetts 02110, is a direct wholly owned subsidiary of Columbia Management Group, Inc. (Columbia), which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to April 1, 2004, Columbia was an indirect wholly owned subsidiary of FleetBoston Financial Corporation, a U.S. financial holding company. Effective April 1, 2004, FleetBoston Financial Corporation was acquired by Bank of America Corporation. The Advisor has been an investment advisor since 1969.

In addition, immediately prior to the mergers described above and also on April 1, 2003, Newport Fund Management, Inc. (NFMI), a subsidiary of NPMI and a registered investment advisor that advised several Funds in the Fund Complex, merged into NPMI. As a result of NPMI's merger into the Advisor, the Advisor is now the Advisor to the Funds previously advised by NFMI.

TRUSTEE POSITIONS

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 101 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The Advisor and/or its affiliate, Colonial Advisory Services, Inc. (CASI), has rendered investment advisory services to investment company, institutional and other clients since 1931. The Advisor currently serves as investment advisor or administrator for 133 open-end and 10 closed-end management investment company portfolios. Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. Columbia Funds Distributor, Inc. (formerly named Liberty Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

35

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund (formerly named Liberty Money Market Fund) and Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund), the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto. The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CFS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CFS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. The Advisor's affiliate, CASI, advises other institutional, corporate, fiduciary and individual clients for which CASI performs various services. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

36

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front-running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to

37

the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

38

PRINCIPAL UNDERWRITER

CFD is the principal underwriter of the Trust's shares. CFD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CFS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CFS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CFS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CFS or generally by 6 months' notice by CFS to the Fund. The agreement limits the liability of CFS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CFS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CFS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CFS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CFS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CFS.

CODE OF ETHICS

The Funds, the Advisor, and CFD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

39

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Management, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Management and its affiliates. The Fund's policies prohibit Columbia Management and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF
TYPE OF FUND           INFORMATION PROVIDED     DISCLOSURE          DATE OF WEB POSTING
------------         -----------------------   ------------   -------------------------------
Equity Funds         Full portfolio holdings   Monthly        30 calendar days after month-
                     information.                             end.
Fixed Income Funds   Full portfolio holdings   Quarterly      60 calendar days after quarter-
                     information.                             end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Funds Distributor, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Management or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

40

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Management and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers(R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Management's trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund), Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Newport Europe Fund (formerly named Liberty Newport Europe Fund) and Columbia Newport Asia Pacific Fund (formerly named Liberty Newport Asia Pacific Fund))

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

41

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET FUND)

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CFS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CFD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CFD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CFD may from time to time reallow additional amounts to all or certain FSFs. CFD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CFD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

42

CFS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CFS, provided the new FSF has a sales agreement with CFD.

Shares credited to an account are transferable upon written instructions in good order to CFS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CFS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CFD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CFD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CFD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CFD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CFD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CFD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CFD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CFD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CFD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Funds Services, Inc. (formerly named Liberty Funds Services, Inc.) (CFS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CFD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CFD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CFD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Management prototype plans offered through CFD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CFD.

46

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CFS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CFS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Management IRA Rollover account in any Fund distributed by CFD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CFS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CFS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Class A, Class B and Class T shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A, B and T shares can be effected by combining a current purchase of Class A, Class B or Class T shares with prior purchases of other funds distributed by CFD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all funds' held by the shareholder.

CFD must be promptly notified of each purchase which entitles a shareholder to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CFS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement. Upon request, a Statement of Intent may be backdated to reflect purchases within 90 days.

During the term of a Statement, CFS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement. The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price. As a part of this adjustment, the FSF shall return to CFD the excess commission previously paid during the thirteen-month period.

If the amount of the Statement is not purchased, the shareholder shall remit to CFD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CFS will redeem that number of escrowed Class A, E or T shares to equal such difference. The additional amount of FSF discount from the applicable offering price shall be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CFS at 1-800-345-6611.

REINSTATEMENT PRIVILEGE. Subject to the Fund's fund policy on trading of fund shares, an investor who has redeemed Class A, B, C or T shares (other than shares of the Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Global Equity Fund (formerly named Liberty Newport Global Equity Fund) and Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) that were redeemed within 30 days of their acquisition by exchange from another fund) may, upon request, reinstate within one year a portion or all of the proceeds of such sale in shares of Class A of any Fund at the NAV next determined after CFS receives a written reinstatement request and payment. Investors who desire to exercise this privilege should contact their FSF or CFS. Shareholders may exercise this privilege an unlimited amount of times. Exercise of this privilege does not alter the federal income tax treatment of any capital gains realized on the prior sale of Fund shares, but to the extent any such shares were sold at a loss, some or all of the loss may be disallowed for tax purposes. Consult your tax advisor.

PRIVILEGES OF COLUMBIA EMPLOYEES OR FINANCIAL SERVICE FIRMS (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS). Class A shares of certain Funds may be sold at NAV to the following individuals whether currently employed or retired: Trustees of funds advised or administered by the Advisor; directors, officers and employees of the Advisor, CFD and companies affiliated with the Advisor; registered representatives and employees of FSFs (including their affiliates) that are parties to dealer agreements or other sales arrangements with CFD; and such persons' families and their beneficial accounts.

PRIVILEGES OF COLUMBIA ACORN FUNDS (FORMERLY NAMED LIBERTY ACORN FUNDS) SHAREHOLDERS. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any fund distributed by CFD, may purchase Class A shares of any fund distributed by CFD at NAV in those cases where a Columbia Fund Class Z share is not available. Qualifying shareholders will not be subject to any Class A initial sales charge or CDSC; however, they will be subject to the annual Rule 12b-1 service fee.

FEE-BASED COMPENSATION ARRANGEMENTS. Class A, Class E and Class T shares (Class T shares can only be purchased by the shareholders of Liberty Newport Tiger Fund who already own Class T shares) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into agreements with CFD pursuant to which the Funds are included as investment options in programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

WAIVER OF INITIAL SALES CHARGES (CLASS A AND CLASS T SHARES)

Class A share initial sales charges (but not contingent deferred sales charges) are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995; and

- Shareholders who (i) purchased Galaxy Fund Prime A Shares at net asset value and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

Class T share sales charges are waived for the following categories of investors:

- Galaxy Fund shareholders prior to December 1, 1995;

- Shareholders who (i) purchased Galaxy Fund Retail A Shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and

- Boston 1784 Fund shareholders on the date the Funds were reorganized into Galaxy Funds.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions within one year following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account occurring within one year after the death. If shares are not redeemed within one year of the death, they will remain subject to the applicable CDSC, when redeemed from the transferee's account. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CFS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met; this requirement does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "Investor Services - Systematic Withdrawal Plan."

48

3. Disability. CDSCs may be waived on redemptions occurring within one year after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by the Advisor.

6. Qualified Retirement Plans. CDSCs may be waived on redemptions required to make distributions from qualified retirement plans following normal retirement (as stated in the Plan document). CDSCs also will be waived on SWP redemptions made to make required minimum distributions from qualified retirement plans that have invested in Funds distributed by CFD for at least two years. CDSC is also waived for participant loans.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CFS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CFS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CFS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CFS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

49

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CFS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CFS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS) (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CFS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred

50

sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CFD to broker-dealer organizations which have entered into agreements with CFD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CFD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CFD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CFD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CFS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CFS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CFS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CFS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CFS may require customary additional documentation. Prospectuses of the other Funds are available from the CFD Literature Department by calling 1-800-426-3750.

53

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CFS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

As described under the caption "Organization and History", the Fund will not hold annual shareholders' meetings. The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose, which meeting shall be held upon written request of the holders of not less than 10% of the outstanding shares of the Trust. Upon written request by the holders of 1% of the outstanding shares of the Trust stating that such shareholders of the Trust, for the purpose of obtaining the signatures necessary to demand a shareholders' meeting to consider removal of a Trustee, request information regarding the Trust's shareholders, the Trust will provide appropriate materials (at the expense of the requesting shareholders). Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

55

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

56

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus (-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

57

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

58

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, Inc.

60

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

61

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

62

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non- independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

63

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

64

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

65

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

66

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

67

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

71

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one- year period.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1986. Each Fund is an open-end, diversified management investment company representing the entire interest in a separate series of the Trust. Each Fund is the successor to a separate series of The Galaxy Fund, a Massachusetts business trust organized on March 31, 1986. On November 25, 2002, each series of The Galaxy Fund to which the Funds succeeded (the "Predecessor Funds") was reorganized as a separate series of the Trust. Class A shares of the Funds were issued in exchange for Prime A Shares of the Predecessor Funds, Class B shares of the Funds were issued in exchange for Prime B Shares of the Predecessor Funds, Class T shares of the Funds were issued in exchange for Retail A Shares of the Predecessor Funds, Class G shares of the Funds were issued in exchange for Retail B Shares of the Predecessor Funds and Class Z shares of the Funds were issued in exchange for Trust Shares of the Predecessor Funds.

The Galaxy Government Income Fund, the predecessor to the Government Income Fund, commenced operations on September 1, 1988, and the Galaxy Quality Plus Bond Fund, the predecessor to the Quality Plus Bond Fund, commenced operations on December 12, 1990.

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. Shareholders receive one vote for each Fund share. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class. Shareholders owning in the aggregate ten percent of Trust shares may call meetings to consider removal of Trustees. Under certain circumstances, the Trust will provide information to assist shareholders in calling such a meeting. See Part 2 of this SAI for more information.

Effective April 1, 1999, the Trust changed its name from "Colonial Trust III" to "Liberty Funds Trust III." Effective October 13, 2003, the Trust changed its name from "Liberty Funds Trust III" to its current name.

Effective October 13, 2003, the Government Income Fund changed its name from "Liberty Intermediate Government Income Fund" to its current name.

Effective October 13, 2003, the Quality Plus Bond Fund changed its name from "Liberty Quality Plus Bond Fund" to its current name.

It is expected that, subject to shareholder approval of the election of all current Trustees, each Fund will be reorganized as a series of Columbia Funds Trust IX, a Massachusetts business trust into which all of the retail Columbia funds are expected to be reorganized.

Except as indicated below under "Fundamental and Non-Fundamental Investment Policies," the Funds' investment policies are not fundamental, and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

FUNDAMENTAL INVESTMENT POLICIES

In addition to each Fund's investment goal as stated in its Prospectuses, the following investment limitations are matters of fundamental policy and may not be changed with respect to a Fund without the affirmative vote of the holders of a majority of its outstanding shares. A "vote of the holders of a majority of the outstanding shares" of a particular Fund means the affirmative vote of the holders of the lesser of (a) more than 50% of the outstanding shares of such Fund, or (b) 67% or more of the shares of such Fund present at a meeting if more than 50% of the outstanding shares of such Fund are represented at the meeting in person or by proxy.

Each of the Funds may not:

1. Borrow money, issue senior securities or mortgage, pledge or hypothecate its assets except to the extent permitted by the Investment Company Act of 1940, as amended (the "1940 Act").

2. Make any investment inconsistent with the Fund's classification as a diversified series of an open-end investment company under the 1940 Act.

3. Concentrate its investments in the securities of one or more issuers conducting their principal business activities in the same industry (other than securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities).

4. Make loans except to the extent permitted by the 1940 Act.

5. Underwrite securities of other issuers, except insofar as the Fund technically may be deemed to be an underwriter under the Securities Act of 1933, as amended (the "1933 Act"), in connection with the purchase and sale of its portfolio securities.

6. Purchase or sell real estate, except that the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate.

7. Purchase or sell commodities or commodity contracts except that the Fund may, to the extent consistent with its investment objective and policies, purchase and sell financial futures contracts and related options and foreign currency forward contracts, futures contracts and related options.

c

With respect to Investment Limitation No. 1 above, the 1940 Act permits a Fund to borrow from any bank, provided that immediately after any such borrowing, there is an asset coverage ratio of at least 300% for all borrowings of the Fund. In addition, a Fund may engage in certain securities trading practices, such as reverse repurchase agreements, that are deemed to be borrowings under the 1940 Act, provided that the Fund maintains in a segregated custodial account liquid assets equal to the repurchase price (including accrued interest). Mortgage dollar rolls and U.S. Treasury rolls entered into by a Fund that are not accounted for as financings shall not constitute borrowings.

With respect to Investment Limitation No. 2 above, the 1940 Act prohibits a diversified Fund from purchasing the securities of any one issuer if immediately after such purchase more than 5% of the value of its total assets would be invested in the securities of such issuer or the Fund would own more than 10% of the outstanding voting securities of such issuer, except that (a) up to 25% of the value of the Fund's total assets may be invested without regard to these limitations and (b) the Fund may invest in U.S. Government obligations without regard to these limitations.

With respect to Investment Limitation No. 4 above, the 1940 Act permits a Fund to lend its portfolio securities against collateral having a value equal at all times to at least 100% of the value of the securities loaned. However, no portfolio securities loan shall be made on behalf of a Fund if, as a result, the aggregate value of all securities loaned by the Fund would exceed 33-1/3% of the value of its total assets (including the value of the collateral for the loans) at the time of the loan. In addition, a Fund may engage in certain securities trading practices, such as repurchase agreements, that are deemed to be loans under the 1940 Act.

The Quality Plus Bond Fund's Trustees have approved, subject to shareholder approval at a shareholder meeting expected to be held in 2005, the replacement of the Fund's current fundamental investment restrictions with the following standardized fundamental investment restrictions (except that municipal funds will retain their current 80% policies required under Rule 35d-1 under the 1940 Act):

PROPOSED FUNDAMENTAL RESTRICTIONS

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the 1933 Act except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and
(b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

d

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and
(b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

NON-FUNDAMENTAL INVESTMENT POLICIES

The following investment limitations with respect to the Funds may be changed by the Board of Trustees without shareholder approval:

1. A Fund may not invest more than 15% of its net assets in illiquid securities.

2. A Fund may invest up to 35% of its total assets in securities of foreign issuers and may also invest in U.S. dollar-denominated obligations of U.S. corporations issued outside the United States.

3. A Fund may not sell securities short, maintain a short position, or purchase securities on margin, except for such short-term credits as are necessary for the clearance of transactions.

4. A Fund may not write or sell put options, call options, straddles, spreads or any combination thereof, except that a Fund may, to the extent consistent with its investment objective and policies, write covered call options and purchase and sell other options.

5. A Fund may not purchase securities of other companies for the purpose of exercising control.

6. A Fund may not purchase securities of other investment companies except as permitted by the 1940 Act.

With respect to Investment Limitation No. 6 above, the 1940 Act prohibits a Fund, subject to certain exceptions, from acquiring the securities of other investment companies if, as a result of such acquisition, (a) the Fund owns more than 3% of the total outstanding voting stock of the investment company; (b) securities issued by any one investment company represent more than 5% of the total assets of the Fund; or (c) securities (other than treasury stock) issued by all investment companies represent more than 10% of the total assets of the Fund.

Each Fund currently intends to limit its investments in securities of other investment companies so that, as determined immediately after a securities purchase is made: (a) not more than 5% of the value of its total assets will be invested in the securities of any one investment company; (b) not more than 10% of the value of its total assets will be invested in the aggregate in securities of other investment companies as a group; (c) not more than 3% of the outstanding voting stock of any one investment company will be owned by the Fund, and (d) not more than 10% of the outstanding voting stock of any one closed-end investment company will be owned in the aggregate by the Funds, other than investment portfolios of the Trust, or any other investment companies advised by the Advisor.

Each Fund may purchase restricted securities, which are any securities in which the Fund may otherwise invest pursuant to its investment objective and policies but which are subject to restrictions on resale under the federal securities laws. Certain restricted securities may be considered liquid pursuant to guidelines established by the Board of Trustees. To the extent restricted securities are deemed illiquid, each Fund will limit its purchase, together with other securities considered to be illiquid, to 15% of its net assets.

The Funds will not engage in futures transactions for speculation, but only to hedge against changes in the market values of securities which the Funds hold or intend to purchase in an effort to manage the impact to the Fund of changes in interest rates.

Each Fund expects that forward commitments, when-issued purchases and delayed settlements will not exceed 25% of the value of the Fund's total assets absent unusual market conditions. In the event a Fund's forward commitments, when-issued purchases and delayed settlements ever exceeded 25% of the value of its total assets, the Fund's liquidity and the ability of the Advisor to manage the Fund might be adversely affected. The Funds do not intend to engage in when-issued purchases, forward commitments and delayed settlements for speculative purposes, but only in furtherance of their investment objectives.

If the rating of a security held by a Fund is downgraded below investment grade, the Fund does not have to sell the security unless (i) the Advisor determines under the circumstances the security is no longer an appropriate investment for the Fund, or (ii) the security, together with any securities held by the Fund that are rated below investment grade, exceed 5% of the Fund's net assets.

e


Except as stated otherwise, if a percentage limitation is satisfied at the time of investment, a later increase in such percentage resulting from a change in the value of a Fund's portfolio securities generally will not constitute a violation of the limitation. If the value of a Fund's holdings of illiquid securities at any time exceeds the percentage limitation applicable at the time of acquisition due to subsequent fluctuations in value or other reasons, the Board of Trustees will consider what actions, if any, are appropriate to maintain adequate liquidity. With respect to borrowings, if a Fund's asset coverage at any time falls below that required by the 1940 Act, the Fund will reduce the amount of its borrowings in the manner required by the 1940 Act to the extent necessary to satisfy the asset coverage requirement.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

Each Fund may follow non-fundamental operating policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectuses and this Statement of Additional Information, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act.

GOVERNMENT INCOME FUND

Under normal circumstances, the Government Income Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt obligations issued or guaranteed by the U.S. Government or its agencies or instrumentalities and repurchase agreements backed by these obligations.

The Government Income Fund may also invest, from time to time, in municipal securities. See "Municipal Securities" in Part 2 of this SAI. The Fund may also enter into interest rate futures contracts in an effort to manage the impact to the Fund of changes in interest rates. See "Futures Contracts and Related Options" in Part 2 of this SAI. In addition, the Fund may invest in obligations issued by Canadian Provincial Governments and in debt obligations of supranational entities. The Fund may not invest more than 35% of its total assets in the securities of foreign issuers. The Fund may also invest in dollar-denominated obligations of U.S. corporations issued outside the United States. Any common stock received through the conversion of convertible debt obligations will be sold in an orderly manner as soon as possible.

QUALITY PLUS BOND FUND

The Quality Plus Bond Fund invests substantially all of its assets (under normal circumstances, at least 80% of net assets plus any borrowings for investment purposes) in investment grade debt obligations.

The Quality Plus Bond Fund may invest, from time to time, in municipal securities. See "Municipal Securities" in Part 2 of this SAI. The Fund may enter into interest rate futures contracts in an effort to manage the impact to the Fund of changes in interest rates. See "Futures Contracts and Related Options" in Part 2 of this SAI. The Fund may also invest in obligations issued by Canadian Provincial Governments and in debt obligations of supranational entities. The Fund may not invest more than 35% of its total assets in the securities of foreign issuers. The Fund may also invest in dollar-denominated obligations of U.S. corporations issued outside the United States. Any common stock received through the conversion of convertible debt obligations will be sold in an orderly manner as soon as possible.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectuses under "Financial Highlights." Each Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment objective. Portfolio investments may be sold for a variety of reasons, such as a more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Funds to realize capital gains, which if realized and distributed by the Funds, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Funds.

FUND CHARGES AND EXPENSES

Each Fund's management agreement with the Advisor has been amended so that, effective February 9, 2005, each fund pays the Advisor a monthly fee based on the average daily net assets of each Fund at the following reduced annual rates:

Columbia Intermediate Government Income Fund

Average Daily Net Assets                               Rate
------------------------                              -----
Net assets under $500 million                         0.460%

Net assets of $3 billion but less than $6 billion     0.340%
Net assets in excess of $6 billion                    0.330%

Columbia Quality Plus Bond Fund

Average Daily Net Assets                               Rate
------------------------                              -----
Net assets under $500 million                         0.480%
Net assets of $500 million but less than $1 billion   0.430%

Net assets in excess of $6 billion                    0.350%

Previously, the Advisor had, with respect to the period from November 1, 2004 to February 9, 2005, waived a portion of its fees, so that it retained fees at the rates shown above.

Prior to November 1, 2004, under each Fund's management agreement, the Fund paid the Advisor a monthly fee at the annual rate of 0.55% of the first $500 million of average daily net assets, 0.50% of the next $500 million of average daily net assets, 0.45% of the next $500 million of average daily net assets, 0.40% of the next $500 million of average daily net assets, 0.35% of average daily net assets in excess of $2 billion.

Prior to November 1, 2003, under each Fund's prior management agreement, each Fund paid the Advisor a monthly fee, at the annual rate of 0.75% of the average daily net assets of each Fund. Effective August 1, 2001, the Advisor had voluntarily agreed to waive its fees so that its actual fees would be as follows: 0.55% of the first $500 million of average daily net assets, 0.50% of the next $500 million of average daily net assets, 0.45% of the next $500 million of average daily net assets, 0.40% of the next $500 million of average daily net assets, 0.35% of average daily net assets in excess of $2 billion.

Under each Fund's administration agreement, the Fund pays the Administrator a monthly fee at the annual rate of 0.067% of the average daily net assets of the Fund.

The Advisor is responsible for providing pricing and bookkeeping services to the Funds pursuant to a pricing and bookkeeping agreement. Under a separate agreement (outsourcing agreement), the Advisor has delegated those functions to State Street Corporation (State Street). The Advisor pays fees to State Street under the outsourcing agreement.

Under its pricing and bookkeeping agreement with the Funds, the Advisor receives from each Fund an annual fee based on the average daily net assets, as follows:

Under $50 million                              $ 25,000
Over $50 million but less than $200 million    $ 35,000
Over $200 million but less than $500 million   $ 50,000
Over $500 million but less than $1 billion     $ 85,000
Over $1 billion                                $125,000

The annual fees for a Fund with more than 25% in non-domestic assets will be 150% of the annual fees described above.

g


The Fund reimburses the Advisor for out-of-pocket expenses and charges, including all fees payable to third parties (other than State Street) for providing pricing data.

Effective November 1, 2003, each Fund pays a shareholders' servicing and transfer agency fee to CMS as follows:

- An annual open account fee of $34 per open account, plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

Prior to November 1, 2003, the Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

- A new account set up charge of $5.00 per account; plus

- An account maintenance fee for each open non-networked account of $14.00 per annum and for each networked account from 0 to 100,000 accounts of $11.00 per annum and each networked account over 100,000 accounts of $8.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- An account fee for each closed account from 0 to 100,000 accounts of $14.00 per annum and each closed account over 100,000 accounts of $11.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- The Fund's allocated shares of CMS' out-of-pocket expenses reasonably incurred by CMS in performing its duties and responsibilities pursuant to this arrangement.

Prior to November 1, 2003, there was a minimum annual fee per Fund of $5,000.

PFPC Inc. (PFPC) (formerly known as First Data Investor Services Group, Inc.), located at 4400 Computer Drive, Westborough, Massachusetts 01581-5108, served as the administrator (until July 2002) and transfer and dividend disbursing agent (until July 2002) for the Predecessor Funds. PFPC is an indirect majority-owned subsidiary of PNC Bank Corp. Prior to July 2002, no administration fees were waived by PFPC.

COMPENSATION

As of each Fund's most recent fiscal year end, the portfolio manager received all of her compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, SHAREHOLDER SERVICING PLAN, CDSCS AND CONVERSION OF SHARES

The Government Income Fund and the Quality Plus Bond Fund offer six classes of shares: Class A, Class B, Class C, Class G, Class T and Class Z. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan (Plan) pursuant to Rule 12b-1 under the Act. Under the Plan, the Funds pay CMD monthly a service fee at an annual rate of 0.25% of each Fund's average daily net assets attributed to Class A, B and C shares. The Funds also may pay CMD monthly a distribution fee at an annual rate of 0.75% of each Fund's average daily net assets attributed to Class B and Class C shares. As of the date of this SAI, CMD is waiving a portion of the distribution fee on Class C, so that it receives 0.60%. The Funds also may pay CMD distribution and service fees up to a maximum of 1.15% of such Fund's average daily net assets attributable to Class G shares (comprised of up to 0.65% for distribution services, up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services). As of the date of this SAI, CMD intends to limit each Fund's payment under the Plan to 0.80% (on an annualized basis) of the average daily net assets of Class G shares owned of record or beneficially by customers of institutions. CMD may use the entire amount of such fees to defray the cost of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of Fund shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in more advantageous expense ratios and increased investment flexibility that could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class T shares of the Funds are subject to a shareholder servicing fee pursuant to a Shareholder Servicing Plan. Under the Shareholder Servicing Plan, a Fund may enter into agreements with institutions pursuant to which an institution agrees to provide certain administrative and support services to its customers who are the beneficial owners of Class T shares. Services provided by such institutions to their customers include aggregating and processing purchase and redemption requests and placing net purchase and redemption orders. In return for providing these services, the Fund agrees to pay each institution a fee at an annual rate of up to 0.50% of the average daily net assets attributable to Class T shares owned beneficially by the institution's customers. Current service arrangements are limited to payments of 0.15% for the Funds.

s


Under the Shareholder Servicing Plan, the Trustees must review, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which those expenditures were made. The initial term of the Shareholder Servicing Plan is one year and it will continue in effect from year to year after its initial one-year term provided that its continuance is specifically approved at least annually by a majority of the Trustees, including a majority of the Independent Trustees who have no direct or indirect financial interest in the operation of the Shareholder Servicing Plan or in any agreement related to it. Any material amendment to the Shareholder Servicing Plan must be approved in the same manner. The Shareholder Servicing Plan is terminable at any time with respect to any Fund by a vote of a majority of the Independent Trustees. While the Shareholder Servicing Plan is in effect, only the Independent Trustees may select and nominate any future Independent Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class G shares are offered at net asset value and are subject to a CDSC if redeemed within a certain number of years after purchase depending on when you purchased your shares that were exchanged for Class G shares. Class T shares are offered at net asset value plus varying sales charges which may include a CDSC. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses for the Funds.

No CDSC will be imposed on shares derived from reinvestment of distributions or amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

A certain number of years, depending on the program you purchased your shares under, after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

A certain number of years, depending on when you purchased your shares that were exchanged for Class G shares, after the end of the month in which you purchased your shares that were exchanged for Class G shares, such Class G shares and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class T shares having an equal value, which are not subject to the distribution fee.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I (formerly named Liberty Funds Trust I), Columbia Funds Trust II (formerly named Liberty Funds Trust II), Columbia Funds Trust III (formerly named Liberty Funds Trust III), Columbia Funds Trust IV (formerly named Liberty Funds Trust IV), Columbia Funds Trust V (formerly named Liberty Funds Trust V), Columbia Funds Trust VI (formerly named Liberty Funds Trust VI), Columbia Funds Trust VII (formerly named Liberty Funds Trust VII), Columbia Funds Trust VIII (formerly named Liberty-Stein Roe Funds Income Trust), Columbia Funds Trust IX (formerly named Liberty-Stein Roe Funds Municipal Trust) and Columbia Funds Trust XI (formerly named Liberty-Stein Roe Funds Investment Trust) (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

1

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

2

ZERO COUPON SECURITIES (ZEROS)

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of

3

one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a

4

time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these

5

ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the

6

financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

7

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing

8

interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the

9

extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

10

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian..

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

11

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

12

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying

13

or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

14

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

15

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward

16

contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate

17

or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus

18

subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers,
(3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities

19

and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are

20

denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation, provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of
(c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

21

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as

22

investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is
(a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

23

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a

24

shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified

25

investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the

26

beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS The Advisor provides administrative and management services to the Funds. On April 1, 2003, Fleet Investment Advisors Inc., Stein Roe & Farnham Incorporated, Colonial Management Associates, Inc. and Newport Pacific Management, Inc. (NPMI), merged into Columbia Management Advisors, Inc. Each of the four merging companies was a registered investment advisor and advised various Funds in the Fund Complex. The Advisor, located at 100 Federal Street, Boston, Massachusetts 02110, is a direct wholly owned subsidiary of Columbia Management Group, Inc. (Columbia), which is an indirect wholly owned subsidiary of Bank of America Corporation. Prior to April 1, 2004, Columbia was an indirect wholly owned subsidiary of FleetBoston Financial Corporation, a U.S. financial holding company. Effective April 1, 2004, FleetBoston Financial Corporation was acquired by Bank of America Corporation. The Advisor has been an investment advisor since 1969.

In addition, immediately prior to the mergers described above and also on April 1, 2003, Newport Fund Management, Inc. (NFMI), a subsidiary of NPMI and a registered investment advisor that advised several Funds in the Fund Complex, merged into NPMI. As a result of NPMI's merger into the Advisor, the Advisor is now the Advisor to the Funds previously advised by NFMI.

TRUSTEE POSITIONS

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 101 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

The Advisor and/or its affiliate, Colonial Advisory Services, Inc. (CASI), has rendered investment advisory services to investment company, institutional and other clients since 1931. The Advisor currently serves as investment advisor or administrator for 133 open-end and 10 closed-end management investment company portfolios. Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

35

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund (formerly named Liberty Money Market Fund) and Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund), the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto. The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Bank and Trust Company (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN

PART 1 OF THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. The Advisor's affiliate, CASI, advises other institutional, corporate, fiduciary and individual clients for which CASI performs various services. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

36

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front- running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel

37

at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate

solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

39

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Management, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Management and its affiliates. The Fund's policies prohibit Columbia Management and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                               FREQUENCY OF
TYPE OF FUND           INFORMATION PROVIDED     DISCLOSURE    DATE OF WEB POSTING
------------         -----------------------   ------------   -------------------
Equity Funds         Full portfolio holdings   Monthly        30 calendar days after month-
                     information.                             end.
Fixed Income Funds   Full portfolio holdings   Quarterly      60 calendar days after quarter-
                     information.                             end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Management Distributors, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Management or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Management and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain

40

Columbia Funds (Fitch, Inc.) and service providers that support Columbia Management's trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund), Columbia Newport Greater China Fund (formerly named Liberty Newport Greater China Fund), Columbia Newport Europe Fund (formerly named Liberty Newport Europe Fund) and Columbia Newport Asia Pacific Fund (formerly named Liberty Newport Asia Pacific Fund))

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET
FUND))

41

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption

42

rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii)

45

processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and
(iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares; (ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Management prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Management IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

46

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program th at has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawalsof shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity

50

of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, INC. ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS) (Available only on the Class A and Z shares of certain Funds) Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

51

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

55

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

As described under the caption "Organization and History", the Fund will not hold annual shareholders' meetings. The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose, which meeting shall be held upon written request of the holders of not less than 10% of the outstanding shares of the Trust. Upon written request by the holders of 1% of the outstanding shares of the Trust stating that such shareholders of the Trust, for the purpose of obtaining the signatures necessary to demand a shareholders' meeting to consider removal of a Trustee, request information regarding the Trust's shareholders, the Trust will provide appropriate materials (at the expense of the requesting shareholders). Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

57

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

58

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

59

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1  Highest Quality
Prime-2  Higher Quality
Prime-3  High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, INC. ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, Inc.

61

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

62

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

63

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

64

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

65

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

66

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2.ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3.ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the

71

interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

(a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

13. The second paragraph of the section entitled "Other Disclosures," a subsection of "Disclosure of Portfolio Information," is revised in its entirety to read:

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers (R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy solicitor and proxy voting service provider (Computershare), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

ORGANIZATION AND HISTORY

Trust I and Series Trust I are Massachusetts business trusts organized in 1985 and 1987, respectively. Each Fund is an open-end diversified management investment company representing the entire interest in a separate series of its respective Trust. The High Yield Fund commenced investment operations on October 21, 1971. The Strategic Income Fund commenced investment operations as a series of the Series Trust I on September 26, 2005. Prior to September 26, 2005 (the "Fund Reorganization Date"), the Strategic Income Fund was organized as a series of Columbia Funds Trust I, a Massachusetts business trust (the "Predecessor Fund") that commenced investment operations on April 21, 1977. The information provided for the Strategic Income Fund in this SAI for periods prior to the Fund Reorganization Date relates to the Predecessor Fund.

The Trust I changed its name from Colonial Trust I to Liberty Funds Trust I on April 1, 1999. Effective October 13, 2003, the Trust I changed its name from Liberty Funds Trust I to its current name. The Series Trust I changed its name from "Liberty-Stein Roe Funds Municipal Trust" to "Columbia Funds Trust IX" effective October 13, 2003. Effective September 19, 2005, the name of the Series Trust I was changed from "Columbia Funds Trust IX" to its current name.

Effective July 14, 2000, the High Yield Fund changed its name from Colonial High Yield Securities Fund to Liberty High Yield Securities Fund. Effective October 13, 2003, the High Yield Fund changed its name from Liberty High Yield Securities Fund to its current name.

Each Fund offers four classes of shares - Class A, B, C and Z shares. The Strategic Income Fund offers an additional class of shares, Class J shares.

It is expected that the High Yield Fund will be reorganized as a series of Series Trust I, into which all of the retail Columbia funds are expected to be reorganized.

Except as indicated below under "Fundamental Investment Policies", the Funds' investment policies are not fundamental, and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or
(2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Each Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies;

2. Purchase or sell real estate, except a Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein;

3. Purchase or sell commodities, except that a Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts;

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief;

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief; and

c

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies, which may be changed without a shareholder vote, each Fund may not:

1. Purchase securities on margin, but the Fund may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;

2. Have a short securities position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities; and

3. Invest more than 15% of its net assets in illiquid assets.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

In addition, the Strategic Income Fund will, so long as shares of the Fund are being offered for sale by the Fund in Japan, comply with the following standards of selection of the Japan Securities Dealers Association:

1. More than 50% of the total number of outstanding shares of stock of any one company may not be acquired on behalf of all funds managed by the Advisor;

2. Borrowing may not be made if it will result in an aggregate amount of borrowing outstanding in excess of 10% of the net assets of the Fund, except in the case of a merger, etc., when this 10% may be temporarily exceeded; and

3. The Strategic Income Fund will not invest in equity securities.

If any violation of the foregoing standards occurs, the Strategic Income Fund will, promptly after discovery of the violation, take such action as may be necessary to cause the violation to cease, which shall be the only obligation of the Fund and the only remedy in respect of the violation.

Except with respect to the Strategic Income Fund's policy on borrowing and investing in illiquid securities, if the Fund's investment limitations, policies and rating standards are adhered to at the time of purchase or utilization of assets; a subsequent change in circumstances will not be considered to result in a violation of policy.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectuses under "Financial Highlights." Each Fund may sell a portfolio investment soon after its acquisition if the Advisor believes that such a disposition is consistent with the Fund's investment goals. Portfolio investments may be sold for a variety of reasons, such as more favorable investment opportunity or other circumstances bearing on the desirability of continuing to hold such investments. A portfolio turnover rate of 100% or more is considered high, although the rate of portfolio turnover will not be a limiting factor in making portfolio decisions. High portfolio turnover may cause the Funds to realize capital gains which, if realized and distributed by a Fund, may be taxable to shareholders as ordinary income. High portfolio turnover may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Funds.

FUND CHARGES AND EXPENSES

Under the High Yield Fund's and Strategic Income Fund's Management Agreement, each Fund pays the Advisor a monthly fee based on the average daily net assets of the Fund at the annual rate of:

Average Daily Net Assets                               Rate
------------------------                              ------
Net assets under $500 million                         0.600%
Net assets of $500 million but less than $1 billion   0.550%
Net assets of $1 billion but less than $1.5 billion   0.520%
Net assets in excess of $1.5 billion                  0.490%

Previously, the Advisor had, with respect to the period from November 1, 2004 to February 9, 2005, waived a portion of its fees, so that it retained fees at the rates shown above.

d

Prior to November 1, 2004, under the High Yield Fund's management agreement, the High Yield Fund paid the Advisor a monthly fee based on the average daily net assets of the High Yield Fund at the annual rate of 0.60% of the first $1 billion, 0.55% of the next $1 billion and 0.50% in excess of $2 billion.

Prior to November 1, 2003, under the High Yield Fund's management agreement, the High Yield Fund paid the Advisor a monthly fee based on the average daily net assets of the High Yield Fund at the annual rate of 0.60% of the first $1.5 billion and 0.55% in excess of $1.5 billion.

Prior to November 1, 2004, under the Strategic Income Fund's management agreement, the Strategic Income Fund paid the Advisor a monthly fee based on the average daily net assets of the Strategic Income Fund at the annual rate of 0.65% on the first $1 billion, 0.60% of the next $1 billion and 0.55% in excess of $2 billion.

The Advisor is responsible for providing pricing and bookkeeping services to the Funds pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Corporation (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement.

Under its pricing and bookkeeping agreement with the Funds, the Advisor receives from each Fund a monthly fee consisting of a flat fee plus an asset-based fee, as follows:

- an annual flat fee of $10,000, paid monthly; and

- in any month that a Fund has average net assets of more than $50 million, a monthly fee equal to the average daily net assets of the Fund for that month multiplied by a fee rate that is calculated by taking into account the fees payable to State Street under the Outsourcing Agreement.

Each Fund reimburses the Advisor for all out-of-pocket expenses and charges, including fees payable to third parties (other than State Street) for providing pricing data.

Effective November 1, 2003, each Fund pays a shareholders' servicing and transfer agency fee to CMS as follows:

An annual open account fee of $34 per open account, plus the Fund's allocated share of reimbursement for the out-of-pocket expenses of CMS.

Prior to November 1, 2003, each Fund paid a shareholders' servicing and transfer agency fee to CMS as follows:

- An account fee for each open account of $4.00 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- An account fee for each closed account of $1.50 per annum, payable on a monthly basis, in an amount equal to 1/12 the per annum charge; plus

- A transaction fee of $1.40 per transaction occurring in Fund accounts during any month; plus

- A monthly fee at the rate of 0.06% per annum of the average daily closing value of the total net assets of each Fund for such month; plus

- Each Fund's allocated share of CMS' out-of-pocket expenses, including fees payable to DST Systems, Inc. (DST) under a remote services agreement with DST.

COMPENSATION

As of the High Yield Fund's and Predecessor Fund's most recent fiscal year end, the portfolio managers received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing each manager's three- and five-year performance. The Advisor may also consider a portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

Each Fund offers four classes of shares - Class A, Class B, Class C and Class Z. The Strategic Income Fund also offers an additional class of shares - Class J shares. The Funds may in the future offer other classes of shares. The Trustees have approved a 12b-1 Plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for each class except for Class Z. Under the Plan, the High Yield Fund pays CMD monthly a service fee at an annual rate of 0.25% of net assets attributed to Class A, B and C shares and the Strategic Income Fund pays CMD monthly a service fee at an annual rate of 0.15% of the Fund's net assets attributed to shares issued on or before January 1, 1993, and a service fee of 0.25% of the Fund's net assets attributed to shares issued and outstanding thereafter. Each Fund also pays CMD monthly a distribution fee at an annual rate of 0.75% of average daily net assets attributed to Class B and Class C shares and the Strategic Income Fund pays CMD monthly a distribution fee at an annual rate of 0.35% of average daily net assets attributed to Class J shares. CMD has voluntarily agreed to waive a portion of the Class C share distribution fee so that it does not exceed 0.60% annually. CMD may terminate this waiver at any time without shareholder approval. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees. The Plan authorizes any other payments by the Funds to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirect financing of the distribution of the Funds' shares.

The Trustees believe the Plan could be a significant factor in the growth and retention of each Fund's assets resulting in a more advantageous expense ratio and increased investment flexibility which could benefit each class of the Funds' shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by a vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments of the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value and are subject to a CDSC if redeemed within six years after purchase. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class J shares are offered at net asset value plus varying sales charges, but not a CDSC. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs and initial sales charges are described in the Prospectuses.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares having an equal value, which are not subject to the distribution fee.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VII, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

SHORT SALES

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

1

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES (ZEROS)

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets.

Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

4

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

5

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

6

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

7

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

8

ASSET-BACKED SECURITIES

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

9

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

10

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events - such as volume in excess of trading or clearing capability - were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian..

11

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges - principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

12

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

13

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets.

14

Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

15

EQUITY SWAPS

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

16

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

17

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

18

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

19

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective. Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

20

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

21

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation, provides that for taxable years of a regulated investment company beginning after October 22, 2004,100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of
(c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

22

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with

23

respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the

24

purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

25

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

26

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

27

Income Taxes

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

CONSULTATION WITH QUALIFIED ADVISOR

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS Columbia Management Advisors, LLC ("Columbia Advisors" or "CMA" or the "Advisor"), located at 100 Federal Street, Boston, Massachusetts 02110 is the Advisor to the Funds. The Advisor provides administrative and management services to the Funds. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005 Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

28

On April 1, 2003, Fleet Investment Advisors Inc., Stein Roe & Farnham Incorporated, Colonial Management Associates, Inc. and Newport Pacific Management, Inc. (NPMI), merged into Columbia Management Advisors, Inc. Each of the four merging companies was a registered investment advisor and advised various Funds in the Fund Complex.

In addition, immediately prior to the mergers described above and also on April 1, 2003, Newport Fund Management, Inc. (NFMI), a subsidiary of NPMI and a registered investment advisor that advised several Funds in the Fund Complex, merged into NPMI. As a result of NPMI's merger into the Columbia Management, Columbia Management became the investment advisor to the Funds previously advised by NFMI.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of 90 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

36

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund and Columbia Municipal Money Market Fund, the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

THE PRICING AND BOOKKEEPING AGREEMENT

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Corporation (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF
THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

37

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front-running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

38

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

ANTI-MONEY LAUNDERING COMPLIANCE

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

PROXY VOTING POLICIES AND FUND PROXY VOTING RECORD

The Fund has delegated to the Advisor the responsibility to vote proxies relating to portfolio securities held by the Fund. In deciding to delegate this responsibility to the Advisor, the Board of Trustees of the Trust reviewed and approved the policies and procedures adopted by the Advisor. These included the procedures that the Advisor follows when a vote presents a conflict between the interests of the Fund and its shareholders and the Advisor, its affiliates, its other clients or other persons.

The Advisor's policy is to vote all proxies for Fund securities in a manner considered by the Advisor to be in the best interest of the Fund and its shareholders without regard to any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor examines each proposal and votes against the proposal, if, in its judgment, approval or adoption of the proposal would be expected to impact adversely the current or potential market value of the issuer's securities. The Advisor also examines each proposal and votes the proxies against the proposal, if, in its judgment, the proposal would be expected to affect adversely the best interest of the Fund. The Advisor determines the best interest of the Fund in light of the potential economic return on the Fund's investment.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

40

The Proxy Committee may vary from a predetermined guideline if it determines that voting on the proposal according to the predetermined guideline would be expected to impact adversely the current or potential market value of the issuer's securities or to affect adversely the best interest of the client. References to the best interest of a client refer to the interest of the client in terms of the potential economic return on the client's investment. In determining the vote on any proposal, the Proxy Committee does not consider any benefit other than benefits to the owner of the securities to be voted. A member of the Proxy Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Committee or its members are required to disclose to the Committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

DISCLOSURE OF PORTFOLIO INFORMATION

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

   TYPE OF FUND              INFORMATION PROVIDED           FREQUENCY OF DISCLOSURE           DATE OF WEB POSTING
   ------------      ------------------------------------   -----------------------   ----------------------------------
   Equity Funds      Full portfolio holdings information.           Monthly            30 calendar days after month-end.
Fixed Income Funds   Full portfolio holdings information.          Quarterly          60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business date after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Management Distributors, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

41

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers(R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds (Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial).These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund and Columbia Newport Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

42

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET
FUND))

Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

43

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients. The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

46

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares;
(ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of THE servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

47

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

48

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

50

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501
(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section
501 (c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

51

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawalsof shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1 % to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS)
(Available only on the Class A and Z shares of certain Funds)

Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

52

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

                                                                    REALLOWANCE TO
                                     REALLOWANCE TO DEALERS        DEALERS AS A % OF

      AMOUNT OF TRANSACTION           PER SHARE-BOND FUNDS     PER SHARE - EQUITY FUNDS
      ---------------------         ------------------------   ------------------------
Less than $50,000                             4.25                       5.00

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Longer than six years                 None

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

                                % DEDUCTED WHEN
HOLDING PERIOD AFTER PURCHASE   SHARES ARE SOLD
-----------------------------   ---------------
Through first year                    5.50
Through second year                   5.00
Through third year                    4.00
Through fourth year                   3.00
Through fifth year                    2.00
Through sixth year                    1.00
Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in

54

which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

SALES CHARGES

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

55

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

56

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

57

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

58

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

59

Plus (+) or minus (-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Ca bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

60

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality
Prime-2 Higher Quality
Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1,2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

61

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

62

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

All proxies(1) regarding client securities for which Columbia Management Advisors, LLC ("CMA") has assumed authority to vote shall, unless CMA determines in accordance with policies stated below to abstain from voting, be voted in a manner considered by CMA to be in the best interest of CMA's clients, including the CMG Family Funds(2) and their shareholders, without regard to any resulting benefit or detriment to CMA or its affiliates. The best interest of clients is defined for this purpose as the interest of enhancing or protecting the economic value of client accounts, considered as a group rather than individually, as CMA determines in its sole and absolute discretion. In the event a client believes that its other interests require a different vote, CMA shall vote as the client clearly instructs, provided CMA receives such instructions in time to act accordingly.

CMA endeavors to vote, in accordance with this Policy, all proxies of which it becomes aware, subject to the following exceptions (unless otherwise agreed) when CMA expects to routinely abstain from voting:

1. Proxies will usually not be voted in cases where the security has been loaned from the Client's account.

2. Proxies will usually not be voted in cases where CMA deems the costs to the Client and/or the administrative inconvenience of voting the security (e.g., some foreign securities) outweigh the benefit of doing so.

CMA seeks to avoid the occurrence of actual or apparent material conflicts of interest in the proxy voting process by voting in accordance with predetermined voting guidelines, as stated below. For those proxy proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guidelines, the CMG Proxy Committee will determine the best interest of CMA's clients and vote accordingly, without consideration of any resulting benefit or detriment to CMA or its affiliates.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

63

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

With Other Bank of America Businesses

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

64

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

65

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

66

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

67

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

68

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. Investment Company Matters

- Board structure

69

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

73

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

b


FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 1940, as amended ("1940 Act"), provides that a "vote of a majority of the outstanding voting securities" means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

The Fund may not, as a matter of fundamental policy:

1. Underwrite any issue of securities issued by other persons within the meaning of the Securities Act of 1933, as amended (the "1933 Act") except when it might be deemed to be an underwriter either: (a) in connection with the disposition of a portfolio security; or (b) in connection with the purchase of securities directly from the issuer thereof in accordance with its investment objective. This restriction shall not limit the Fund's ability to invest in securities issued by other registered investment companies.

2. Purchase or sell real estate, except the Fund may purchase securities of issuers which deal or invest in real estate and may purchase securities which are secured by real estate or interests in real estate and it may hold and dispose of real estate or interests in real estate acquired through the exercise of its rights as a holder of securities which are secured by real estate or interests therein.

3. Purchase or sell commodities, except that the Fund may to the extent consistent with its investment objective, invest in securities of companies that purchase or sell commodities or which invest in such programs, and purchase and sell options, forward contracts, futures contracts, and options on futures contracts and enter into swap contracts and other financial transactions relating to commodities. This limitation does not apply to foreign currency transactions including without limitation forward currency contracts.

4. Purchase any securities which would cause 25% or more of the value of its total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that: (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. Government, any state or territory of the United States, or any of their agencies, instrumentalities or political subdivisions; and (b) notwithstanding this limitation or any other fundamental investment limitation, assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

5. Make loans, except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

6. Borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief.

7. Purchase securities (except securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities) of any one issuer if, as a result, more than 5% of its total assets will be invested in the securities of such issuer or it would own more than 10% of the voting securities of such issuer, except that: (a) up to 25% of its total assets may be invested without regard to these limitations and (b) a Fund's assets may be invested in the securities of one or more management investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

As non-fundamental investment policies, which may be changed without a shareholder vote, the Fund may not:

1. Purchase securities on margin, but it may receive short-term credit to clear securities transactions and may make initial or maintenance margin deposits in connection with futures transactions;

2. Have a short securities position, unless the Fund owns, or owns rights (exercisable without payment) to acquire, an equal amount of such securities;

3. Invest more than 15% of its net assets in illiquid assets.

Total assets and net assets are determined at current value for purposes of compliance with investment restrictions and policies. All percentage limitations will apply at the time of investment and are not violated unless an excess or deficiency occurs as a result of such investment. For the purpose of the 1940 Act's diversification requirement, an issuer is the entity whose revenues support the security.

c

FUND CHARGES AND EXPENSES

Under the Fund's Management Agreement, the Fund pays the Advisor a monthly fee based on average daily net assets of the Fund, at the following annual rates:
0.450% up to $100 million, 0.425% next $100 million and 0.400% thereafter.

The Advisor provides certain pricing and bookkeeping services to the Fund. Effective November 1, 2005, the Fund entered into a Pricing and Bookkeeping Agreement with the Advisor. For services provided under the Pricing and Bookkeeping Agreement, the Fund will pay the Advisor an annual fee, payable monthly, consisting of: (i) a fixed fee plus an asset-based fee for fund accounting services ("Fund Accounting Fee"); (ii) a fixed fee for financial reporting services ("Financial Reporting Fee"); (iii) a fixed fee for fair value pricing services ("Fair Value Pricing Fee") and (iv) a fixed fee for each additional portfolio manager managing a portion of the Fund ("Multi-Manager Fee"). During any 12-month period, the aggregate Fund Accounting Fee and Financial Reporting Fee for the Fund will not exceed a specified maximum amount. The Fund will also reimburse the Advisor for its internal direct costs related to fund accounting, security valuation and monitoring, budgeting and approving fund expenses. The Advisor has delegated responsibility for certain pricing and bookkeeping functions to State Street Bank and Trust Company ("State Street"). For periods before November 1, 2005, the Fund paid the Adviser fees under a similar Pricing and Bookkeeping Agreement at different rates, based in part on the Fund's net assets, subject to a minimum amount per annum.

COMPENSATION

As of each Fund's most recent fiscal year end, the portfolio manager received all of their compensation from the Advisor and its parent company, Columbia Management Group, in the form of salary, bonus, stock options and restricted stock. A portfolio manager's bonus is variable and is generally based on (1) an evaluation of the manager's investment performance and (2) the results of a peer and/or management review of such individual, which takes into account skills and attributes such as team participation, investment process, communication and professionalism. In evaluating investment performance, the Advisor generally considers the one-, three- and five-year performance of mutual funds and other accounts under the portfolio manager's oversight relative to the benchmarks and peer groups noted below, emphasizing the manager's three- and five-year performance. The Advisor may also consider the portfolio manager's performance in managing client assets in sectors and industries assigned to the manager as part of his or her investment team responsibilities, where applicable. For portfolio managers who also have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance.

Stephen D. Barbaro   Russell 2000 Value Index   Morningstar Small Value Category
Jeremy Javidi        Russell 2000 Value Index   Morningstar Small Value Category

The size of the overall bonus pool each year is determined by Columbia Management Group and depends in part on levels of compensation generally in the investment management industry (based on market compensation data) and the Advisor's profitability for the year, which is influenced by assets under management.

Aggregate CDSCs on Fund redemptions retained by CMD    $8     $4     $3

12B-1 PLAN, CDSC AND CONVERSION OF SHARES

The Fund offers four classes of shares - Class A, Class B, Class C and Class Z. The Fund may in the future offer other classes of shares. The Trustees have approved a 12b-1 plan (Plan) pursuant to Rule 12b-1 under the 1940 Act for each of Classes A, B and C. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.25% of the net assets attributed to Classes A, B and C. The Fund also pays CMD monthly a distribution fee at an annual rate of 0.75% of the average daily net assets attributed to Classes B and C. CMD may use the entire amount of such fees to defray the costs of commissions and service fees paid to financial service firms (FSFs) and for certain other purposes. Since the distribution and service fees are payable regardless of the amount of CMD's expenses, CMD may realize a profit from the fees.

The Plan authorizes any other payments by the Fund to CMD and its affiliates (including the Advisor) to the extent that such payments might be construed to be indirectly financing the distribution of Fund shares.

j


The Trustees believe the Plan could be a significant factor in the growth and retention of Fund assets resulting in a more advantageous expense ratio and increased investment flexibility that could benefit each class of Fund shareholders. The Plan will continue in effect from year to year so long as continuance is specifically approved at least annually by vote of the Trustees, including the Trustees who are not interested persons of the Trust and have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (Independent Trustees), cast in person at a meeting called for the purpose of voting on the Plan. The Plan may not be amended to increase the fee materially without approval by vote of a majority of the outstanding voting securities of the relevant class of shares and all material amendments to the Plan must be approved by the Trustees in the manner provided in the foregoing sentence. The Plan may be terminated at any time by vote of a majority of the Independent Trustees or by vote of a majority of the outstanding voting securities of the relevant class of shares. The continuance of the Plan will only be effective if the selection and nomination of the Trustees of the Trust who are not interested persons of the Trust is effected by such disinterested Trustees.

Class A shares are offered at net asset value plus varying sales charges which may include a CDSC. Class B shares are offered at net asset value subject to a CDSC if redeemed within a certain number of years after purchase depending on the program you purchased your shares under. Class C shares are offered at net asset value and are subject to a 1.00% CDSC on redemptions within one year after purchase. Class Z shares are offered at net asset value and are not subject to a CDSC. The CDSCs are described in the Prospectuses for the Fund.

No CDSC will be imposed on shares derived from reinvestment of distributions or on amounts representing capital appreciation. In determining the applicability and rate of any CDSC, it will be assumed that a redemption is made first of shares representing capital appreciation, next of shares representing reinvestment of distributions and finally of other shares held by the shareholder for the longest period of time.

Eight years, after the end of the month in which a Class B share is purchased, such share and a pro rata portion of any shares issued on the reinvestment of distributions will be automatically converted into Class A shares, having an equal value, which are not subject to the distribution fee. See the prospectus for a description of the different programs.

STATEMENT OF ADDITIONAL INFORMATION

PART 2

The following information applies generally to most funds advised by the Advisor. "Funds" include the series of Columbia Funds Trust I, Columbia Funds Trust II, Columbia Funds Trust III, Columbia Funds Trust IV, Columbia Funds Trust V, Columbia Funds Trust VI, Columbia Funds Trust VII, Columbia Funds Trust VIII, Columbia Funds Series Trust I (formerly named Columbia Funds Trust IX) and Columbia Funds Trust XI (each a Trust and together, the Trusts, also known as Fund Complex). In certain cases, the discussion applies to some, but not all, of the Funds, and you should refer to your Fund's Prospectus and to Part 1 of this Statement of Additional Information (SAI) to determine whether the matter is applicable to your Fund. You will also be referred to Part 1 for certain data applicable to your Fund.

MISCELLANEOUS INVESTMENT PRACTICES

PART 1 OF THIS SAI LISTS ON PAGE B WHICH OF THE FOLLOWING INVESTMENT PRACTICES

ARE AVAILABLE TO YOUR FUND. IF AN INVESTMENT PRACTICE IS NOT LISTED IN PART 1 OF THIS SAI, IT IS NOT APPLICABLE TO YOUR FUND.

SHORT-TERM TRADING

In seeking the Fund's investment goal, the Advisor will buy or sell portfolio securities whenever it believes it is appropriate. The Advisor's decision will not generally be influenced by how long the Fund may have owned the security. From time to time, the Fund will buy securities intending to seek short-term trading profits. A change in the securities held by the Fund is known as "portfolio turnover" and generally involves some expense to the Fund. These expenses may include brokerage commissions or dealer mark-ups and other transaction costs on both the sale of securities and the reinvestment of the proceeds in other securities. If sales of portfolio securities cause the Fund to realize net short-term capital gains, such gains will be taxable as ordinary income. As a result of the Fund's investment policies, under certain market conditions the Fund's portfolio turnover rate may be higher than that of other mutual funds. The Fund's portfolio turnover rate for a fiscal year is the ratio of the lesser of purchases or sales of portfolio securities to the monthly average of the value of portfolio securities, excluding securities whose maturities at acquisition were one year or less. The Fund's portfolio turnover rate is not a limiting factor when the Advisor considers a change in the Fund's portfolio.

Short Sales

A Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. In order to deliver the security to the buyer, the Fund borrows the security from a third party. The Fund is then obligated to return the security to the third party, so the Fund must purchase the security at the market price at a later point in time. If the price of the security has increased during this time, then the Fund will incur a loss equal to the increase in price of the security from the time that the short sale was entered into plus any premiums and interest paid to the third party. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the security. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

LOWER-RATED DEBT SECURITIES

Lower-rated debt securities are those rated lower than Baa by Moody's or BBB by S&P, or comparable unrated debt securities. Relative to debt securities of higher quality,

1. an economic downturn or increased interest rates may have a more significant effect on the yield, price and potential for default for lower-rated debt securities;

2. the secondary market for lower-rated debt securities may at times become less liquid or respond to adverse publicity or investor perceptions, increasing the difficulty in valuing or disposing of the bonds;

3. the Advisor's credit analysis of lower-rated debt securities may have a greater impact on the Fund's achievement of its investment goal; and

4. lower-rated debt securities may be less sensitive to interest rate changes, but are more sensitive to adverse economic developments.

1

In addition, certain lower-rated debt securities may not pay interest in cash on a current basis.

SMALL COMPANIES

Smaller, less well established companies may offer greater opportunities for capital appreciation than larger, better established companies, but may also involve certain special risks related to limited product lines, markets, or financial resources and dependence on a small management group. Their securities may trade less frequently, in smaller volumes, and fluctuate more sharply in value than securities of larger companies.

COMMON STOCK, PREFERRED STOCK AND WARRANTS

Common stocks are generally more volatile than other securities. Preferred stocks share some of the characteristics of both debt and equity investments and are generally preferred over common stocks with respect to dividends and in liquidation. A warrant is an instrument issued by a corporation which gives the holder the right to subscribe to a specified amount of the company's capital stock at a set price for a specified period of time.

FOREIGN SECURITIES

The Fund may invest in securities traded in markets outside the United States. Foreign investments can be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards comparable to those applicable to U.S. companies. Securities of some foreign companies are less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees may be higher than in the United States. Investments in foreign securities can involve other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. Foreign securities, like other assets of the Fund, will be held by the Fund's custodian or by a sub-custodian or depository. See also "Foreign Currency Transactions" below.

The Fund may invest in certain Passive Foreign Investment Companies (PFICs) which may be subject to U.S. federal income tax on a portion of any "excess distribution" or gain (PFIC tax) related to the investment. This "excess distribution" will be allocated over the Fund's holding period for such investment. The PFIC tax is the highest ordinary income rate in effect for any period multiplied by the portion of the "excess distribution" allocated to such period, and it could be increased by an interest charge on the deemed tax deferral.

The Fund may possibly elect to include in its income its pro rata share of the ordinary earnings and net capital gain of PFICs. This election requires certain annual information from the PFICs which in many cases may be difficult to obtain. An alternative election would permit the Fund to recognize as income any appreciation (and to a limited extent, depreciation) on its holdings of PFICs as of the end of its fiscal year. See "Taxes" below.

The Fund may invest in other investment companies. Such investments will involve the payment of duplicative fees through the indirect payment of a portion of the expenses, including advisory fees, of such other investment companies.

EXCHANGE-TRADED FUNDS ("ETFS"). The Fund may invest in ETFs up to the maximum amount allowable under the 1940 Act. ETFs are shares of publicly-traded unit investment trusts, open-end funds, or depositary receipts that seek to track the performance and dividend yield of specific indexes or companies in related industries. These indexes may be either broad-based, sector or international.

ETF shareholders are generally subject to the same risks as holders of the underlying securities they are designed to track. ETFs are also subject to certain additional risks, including (1) the risk that their prices may not correlate perfectly with changes in the prices of the underlying securities they are designed to track; and (2) the risk of possible trading halts due to market conditions or other reasons, based on the policies of the exchange upon which an ETF trades. In addition, an exchange traded sector fund may be adversely affected by the performance of that specific sector or group of industries on which it is based.

The Fund would bear, along with other shareholders of an ETF, its pro rata portion of the ETF's expenses, including management fees. Accordingly, in addition to bearing their proportionate share of the Fund's expenses (i.e., management fees and operating expenses), shareholders of the Fund may also indirectly bear similar expenses of an ETF.

ZERO COUPON SECURITIES (ZEROS)

2

The Fund may invest in zero coupon securities, which are securities issued at a significant discount from face value and do not pay interest at intervals during the life of the security. Zero coupon securities include securities issued in certificates representing undivided interests in the interest or principal of mortgage-backed securities (interest only/principal only), which tend to be more volatile than other types of securities. The Fund will accrue and distribute income from stripped securities and certificates on a current basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

The Fund may invest in debt securities which pay interest at a series of different rates (including 0%) in accordance with a stated schedule for a series of periods. In addition to the risks associated with the credit rating of the issuers, these securities may be subject to more volatility risk than fixed rate debt securities.

TENDER OPTION BONDS

A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term tax-exempt rates, that has been coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, pursuant to which such institution grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the municipal security's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term tax-exempt rate. The Advisor will consider on an ongoing basis the creditworthiness of the issuer of the underlying municipal securities, of any custodian, and of the third-party provider of the tender option. In certain instances and for certain tender option bonds, the option may be terminable in the event of a default in payment of principal or interest on the underlying municipal securities and for other reasons.

PAY-IN-KIND (PIK) SECURITIES

The Fund may invest in securities which pay interest either in cash or additional securities. These securities are generally high yield securities and, in addition to the other risks associated with investing in high yield securities, are subject to the risks that the interest payments which consist of additional securities are also subject to the risks of high yield securities.

MONEY MARKET INSTRUMENTS

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. SUPRANATIONAL OBLIGATIONS are issued by supranational entities and are generally designed to promote economic improvements. CERTIFICATES OF DEPOSIT are issued against deposits in a commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are used to finance the import, export or storage of goods and are "accepted" when guaranteed at maturity by a bank. COMMERCIAL PAPER is a promissory note issued by a business to finance short-term needs (including promissory notes with floating or variable interest rates, or including a frequent interval put feature). SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to maturity at the time of purchase) issued by businesses to finance long-term needs. PARTICIPATION INTERESTS include the underlying securities and any related guaranty, letter of credit, or collateralization arrangement in which the Fund would be allowed to invest directly.

CERTIFICATES OF DEPOSIT are short-term negotiable instruments issued against deposits in a commercial bank with a defined return and maturity. TIME DEPOSITS are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates.

GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their subdivisions, agencies and instrumentalities. Examples of the types of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities (hereinafter, "U.S. Government obligations") that may be held by the Funds include, without limitation, direct obligations of the U.S. Treasury, and securities issued or guaranteed by the Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association, Federal National Mortgage Association, General Services Administration, Central Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate Credit Banks, Resolution Trust Corporation and Maritime Administration.

U.S. Treasury securities differ only in their interest rates, maturities and time of issuance: Treasury Bills have initial maturities of one year or less; Treasury Notes have initial maturities of one to ten years; and Treasury Bonds generally have initial maturities

3

of more than ten years. Obligations of certain agencies and instrumentalities of the U.S. Government, such as those of the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, such as those of the Federal Home Loan Mortgage Corporation, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. Government would provide financial support to U.S. Government-sponsored instrumentalities if it is not obligated to do so by law. Some of these instruments may be variable or floating rate instruments.

Securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities have historically involved relatively little risk of loss of principal. However, due to fluctuations in interest rates, the market value of such securities may vary during the period a shareholder owns shares of the Fund.

BANK OBLIGATIONS include bankers' acceptances, negotiable certificates of deposit, and non-negotiable time deposits issued for a definite period of time and earning a specified return by a U.S. bank which is a member of the Federal Reserve System or is insured by the Federal Deposit Insurance Corporation ("FDIC"), or by a savings and loan association or savings bank which is insured by the FDIC. Bank obligations also include U.S. dollar-denominated obligations of foreign branches of U.S. banks or of U.S. branches of foreign banks, all of the same type as domestic bank obligations. Time deposits with a maturity longer than seven days or that do not provide for payment within seven days after notice will be subject to any limitations on illiquid securities described in Part 1 of this SAI. For purposes of each Fund's investment policies with respect to bank obligations, the assets of a bank or savings institution will be deemed to include the assets of its U.S. and foreign branches.

Domestic and foreign banks are subject to extensive but different government regulation which may limit the amount and types of their loans and the interest rates that may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds to finance lending operations and the quality of underlying bank assets. Investments in obligations of foreign branches of U.S. banks and of U.S. branches of foreign banks may subject a Fund to additional risks, including future political and economic developments, the possible imposition of withholding taxes on interest income, possible seizure or nationalization of foreign deposits, the possible establishment of exchange controls, or the adoption of other foreign governmental restrictions which might adversely affect the payment of principal and interest on such obligations. In addition, foreign branches of U.S. banks and U.S. branches of foreign banks may be subject to less stringent reserve requirements and to different accounting, auditing, reporting, and recordkeeping standards than those applicable to domestic branches of U.S. banks.

SEPARATELY TRADED INTEREST AND PRINCIPAL SECURITIES ("STRIPS") are component parts of U.S. Treasury Securities traded through the Federal Reserve Book-Entry System. While there is no limitation on the percentage of a Fund's assets that may be invested in STRIPS, the Advisor will monitor the level of such holdings to avoid the risk of impairing shareholders' redemption rights. The interest-only component of STRIPS is extremely sensitive to the rate of principal payments on the underlying obligation. The market value of the principal-only component is usually volatile in response to changes in interest rates.

In U.S. TREASURY ROLLS, a Fund sells outstanding U.S. Treasury securities and buys back on a delayed settlement basis the same U.S. Treasury securities. During the period prior to the delayed settlement date, the assets from the sale of the U.S. Treasury securities are invested in certain cash equivalent instruments. U.S. Treasury rolls entail the risk that the Fund could suffer an opportunity loss if the counterparty to the roll failed to perform its obligations on the settlement date, and if market conditions changed adversely. The Funds intend to enter into U.S. Treasury rolls only with U.S. Government securities dealers recognized by the Federal Reserve Bank or with member banks of the Federal Reserve System. The Funds will hold and maintain in a segregated account until the settlement date cash or other liquid assets in an amount equal to the forward purchase price. For financial reporting and tax purposes, the Funds propose to treat U.S. Treasury rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale.

COMMERCIAL PAPER is an unsecured short-term promissory note issued by businesses to finance short-term needs (including those with floating or variable interest rates, or including a frequent interval put feature). Commercial paper may include variable and floating rate instruments which are unsecured instruments that permit the indebtedness thereunder to vary. Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of

4

variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event that an issuer of a variable or floating rate obligation were to default on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default.

Commercial paper may include securities issued by corporations without registration under the 1933 Act in reliance on the so-called "private placement" exemption in Section 4(2) ("Section 4(2) Paper"). Section 4(2) Paper is restricted as to disposition under the federal securities laws in that any resale must similarly be made in an exempt transaction. Section 4(2) Paper is normally resold to other institutional investors through or with the assistance of investment dealers who make a market in Section 4(2) Paper, thus providing liquidity. For purposes of each Fund's limitation on purchases of illiquid instruments described below, Section 4(2) Paper will not be considered illiquid if the Advisor has determined, in accordance with guidelines approved by the Board of Trustees, that an adequate trading market exists for such securities.

STRIPPED OBLIGATIONS

To the extent consistent with their investment objective, Funds may purchase U.S. Treasury receipts and other "stripped" securities that evidence ownership in either the future interest payments or the future principal payments on U.S. Government and other obligations. These participations, which may be issued by the U.S. Government or by private issuers, such as banks and other institutions, are issued at their "face value," and may include stripped mortgage-backed securities ("SMBS"), which are derivative multi-class mortgage securities. Stripped securities, particularly SMBS, may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors.

SMBS are usually structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed obligations. A common type of SMBS will have one class receiving all of the interest, while the other class will receive all of the principal. However, in some instances, one class will receive some of the interest and most of the principal while the other class will receive most of the interest and the remainder of the principal. If the underlying obligations experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities. The market value of the class consisting entirely of principal payments generally is extremely volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest are generally higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. SMBS which are not issued by the U.S. Government (or a U.S. Government agency or instrumentality) are considered illiquid by the Funds. Obligations issued by the U.S. Government may be considered liquid under guidelines established by Funds' Board of Trustees if they can be disposed of promptly in the ordinary course of business at a value reasonably close to that used in the calculation of net asset value per share.

MUNICIPAL SECURITIES

Municipal Securities acquired by the Funds include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately operated facilities are "Municipal Securities" if the interest paid thereon is exempt from regular federal income tax and not treated as a specific tax preference item under the federal alternative minimum tax.

The two principal classifications of Municipal Securities which may be held by the Funds are "general obligation" securities and "revenue" securities. General obligation securities are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as the user of the facility being financed.

The Fund's portfolio may also include "moral obligation" securities, which are normally issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the state or municipality which created the issuer. There is no limitation on the amount of moral obligation securities that may be held by the Funds.

There are, of course, variations in the quality of Municipal Securities, both within a particular category and between categories, and the yields on Municipal Securities depend upon a variety of factors, including general market conditions, the financial

5

condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of a nationally recognized statistical rating organization ("NRSRO"), such as Moody's and S&P, represent such NRSRO's opinion as to the quality of Municipal Securities. It should be emphasized that these ratings are general and are not absolute standards of quality. Municipal Securities with the same maturity, interest rate and rating may have different yields. Municipal Securities of the same maturity and interest rate with different ratings may have the same yield.

Municipal Securities may include rated and unrated variable and floating rate tax-exempt instruments, such as variable rate demand notes. Variable rate demand notes are long-term Municipal Securities that have variable or floating interest rates and provide a Fund with the right to tender the security for repurchase at its stated principal amount plus accrued interest. Such securities typically bear interest at a rate that is intended to cause the securities to trade at par. The interest rate may float or be adjusted at regular intervals (ranging from daily to annually), and is normally based on an applicable interest index or another published interest rate or interest rate index. Most variable rate demand notes allow a Fund to demand the repurchase of the security on not more than seven days prior notice. Other notes only permit a Fund to tender the security at the time of each interest rate adjustment or at other fixed intervals. Variable interest rates generally reduce changes in the market value of Municipal Securities from their original purchase prices. Accordingly, as interest rates decrease, the potential for capital appreciation is less for variable rate Municipal Securities than for fixed income obligations. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the Municipal Securities, the issuer of the participation interest or a guarantor of either issuer.

Municipal Securities purchased by the Funds in some cases may be insured as to the timely payment of principal and interest. There is no guarantee, however, that the insurer will meet its obligations in the event of a default in payment by the issuer. In other cases, Municipal Securities may be backed by letters of credit or guarantees issued by domestic or foreign banks or other financial institutions which are not subject to federal deposit insurance. Adverse developments affecting the banking industry generally or a particular bank or financial institution that has provided its credit or guarantee with respect to a Municipal Security held by a Fund, including a change in the credit quality of any such bank or financial institution, could result in a loss to the Fund and adversely affect the value of its shares. Letters of credit and guarantees issued by foreign banks and financial institutions involve certain risks in addition to those of similar instruments issued by domestic banks and financial institutions.

The payment of principal and interest on most Municipal Securities purchased by the Funds will depend upon the ability of the issuers to meet their obligations. Each state, the District of Columbia, each of their political subdivisions, agencies, instrumentalities and authorities and each multi-state agency of which a state is a member is a separate "issuer" as that term is used in this SAI and the Prospectuses. The non-governmental user of facilities financed by private activity bonds is also considered to be an "issuer." An issuer's obligations under its Municipal Securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code and laws, if any, which may be enacted by federal or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its Municipal Securities may be materially adversely affected by litigation or other conditions.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on Municipal Securities. For example, under the Tax Reform Act of 1986, interest on certain private activity bonds must be included in an investor's federal alternative minimum taxable income, and corporate investors must include all tax-exempt interest in their federal alternative minimum taxable income. The Funds cannot, of course, predict what legislation may be proposed in the future regarding the income tax status of interest on Municipal Securities, or which proposals, if any, might be enacted. Such proposals, while pending or if enacted, might materially and adversely affect the availability of Municipal Securities for investment by the Funds and the liquidity and value of their respective portfolios. In such an event, each Fund would re-evaluate its investment objective and policies and consider possible changes in its structure or possible dissolution.

Opinions relating to the validity of Municipal Securities and to the exemption of interest thereon from federal income tax are rendered by bond counsel to the respective issuers at the time of issuance. Neither the Funds nor the Advisor will review the proceedings relating to the issuance of Municipal Securities or the bases for such opinions.

6

PRIVATE ACTIVITY BONDS

The Funds may invest in "private activity bonds," the interest on which, although exempt from regular federal income tax, may constitute an item of tax preference for purposes of the federal alternative minimum tax. Private activity bonds are or have been issued to obtain funds to provide, among other things, privately operated housing facilities, pollution control facilities, convention or trade show facilities, mass transit, airport, port or parking facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. Private activity bonds are also issued to privately held or publicly owned corporations in the financing of commercial or industrial facilities. State and local governments are authorized in most states to issue private activity bonds for such purposes in order to encourage corporations to locate within their communities. The principal and interest on these obligations may be payable from the general revenues of the users of such facilities.

Private activity bonds held by the Funds are in most cases revenue securities and are not payable from the unrestricted revenues of the issuer. Consequently, the credit quality of such private activity bonds is usually directly related to the credit standing of the corporate user of the facility involved.

MUNICIPAL LEASE OBLIGATIONS

Although a municipal lease obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a municipal lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the municipal lease obligation. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although "non-appropriation" lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear.

Determinations concerning the liquidity and appropriate valuation of a municipal lease obligation, as with any other municipal security, are made based on all relevant factors. These factors include, among others: (1) the frequency of trades and quotes for the obligation; (2) the number of dealers willing to purchase or sell the security and the number of other potential buyers; (3) the willingness of dealers to undertake to make a market in the security; and (4) the nature of the marketplace trades, including the time needed to dispose of the security, the method of soliciting offers, and the mechanics of the transfer.

SECURITIES LOANS

The Fund may make secured loans of its portfolio securities amounting to not more than the percentage of its total assets specified in Part 1 of this SAI, thereby realizing additional income. The risks in lending portfolio securities, as with other extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a matter of policy, securities loans are made to banks and broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the value of the securities on loan. The borrower pays to the Fund an amount equal to any dividends or interest received on securities lent. The Fund retains all or a portion of the interest received on investment of the cash collateral or receives a fee from the borrower. Although voting rights, or rights to consent, with respect to the loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved.

INTERFUND BORROWING AND LENDING

The Fund may lend money to and borrow money from other affiliated registered open-end investment companies. The Fund may borrow through the program when the Advisor believes borrowing is appropriate and the costs are equal to or lower than the costs of bank loans. When borrowing money, the Fund is subject to the risk that the securities the Fund acquires with the borrowed money or would otherwise have sold will decline in value. When lending money, the Fund is subject to the risk that the borrower will be unwilling or unable to make timely payments of interest or principal.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)

The Fund may enter into contracts to purchase securities for a fixed price at a future date beyond customary settlement time ("forward commitments" and "when-issued securities") if the Fund holds until the settlement date, in a segregated account, cash or liquid securities in an amount sufficient to meet the purchase price, or if the Fund enters into offsetting contracts for the forward sale of other securities it owns. Forward commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date. Where such purchases are made through

7

dealers, the Fund relies on the dealer to consummate the sale. The dealer's failure to do so may result in the loss to the Fund of an advantageous yield or price. Although the Fund will generally enter into forward commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the Fund may dispose of a commitment prior to settlement if the Advisor deems it appropriate to do so. The Fund may realize short-term profits or losses (generally taxed at ordinary income tax rates in the hands of the shareholders) upon the sale of forward commitments.

MORTGAGE DOLLAR ROLLS

In a mortgage dollar roll, the Fund sells a mortgage-backed security and simultaneously enters into a commitment to purchase a similar security at a later date. The Fund either will be paid a fee by the counterparty upon entering into the transaction or will be entitled to purchase the similar security at a discount. As with any forward commitment, mortgage dollar rolls involve the risk that the counterparty will fail to deliver the new security on the settlement date, which may deprive the Fund of obtaining a beneficial investment. In addition, the security to be delivered in the future may turn out to be inferior to the security sold upon entering into the transaction. In addition, the transaction costs may exceed the return earned by the Fund from the transaction.

REITS

The Funds may invest in real estate investment trusts ("REITs"). Equity REITs invest directly in real property while mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real estate, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, and variations in rental income. Generally, increases in interest rates will decrease the value of high yielding securities and increase the costs of obtaining financing, which could decrease the value of a REIT's investments. In addition, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of credit extended. Equity and mortgage REITs are dependent upon management skill, are not diversified and are subject to the risks of financing projects. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code of 1986, as amended (the "Code"), and to maintain exemption from the 1940 Act. REITs pay dividends to their shareholders based upon available funds from operations. It is quite common for these dividends to exceed a REIT's taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. The Funds intend to include the gross dividends from any investments in REITs in their periodic distributions to its shareholders and, accordingly, a portion of the Fund's distributions may also be designated as a return of capital.

Mortgage-Backed Securities

Mortgage-backed securities, including "collateralized mortgage obligations" (CMOs) and "real estate mortgage investment conduits" (REMICs), evidence ownership in a pool of mortgage loans made by certain financial institutions that may be insured or guaranteed by the U.S. government or its agencies. CMOs are obligations issued by special-purpose trusts, secured by mortgages. REMICs are entities that own mortgages and elect REMIC status under the Internal Revenue Code. Both CMOs and REMICs issue one or more classes of securities of which one (the Residual) is in the nature of equity. The Funds will not invest in the Residual class. Principal on mortgage-backed securities, CMOs and REMICs may be prepaid if the underlying mortgages are prepaid. Prepayment rates for mortgage-backed securities tend to increase as interest rates decline (effectively shortening the security's life) and decrease as interest rates rise (effectively lengthening the security's life). Because of the prepayment feature, these securities may not increase in value as much as other debt securities when interest rates fall. A Fund may be able to invest prepaid principal only at lower yields. The prepayment of such securities purchased at a premium may result in losses equal to the premium.

NON-AGENCY MORTGAGE-BACKED SECURITIES

The Fund may invest in non-investment grade mortgage-backed securities that are not guaranteed by the U.S. government or an agency. Such securities are subject to the risks described under "Lower Rated Debt Securities" and "Mortgage-Backed Securities." In addition, although the underlying mortgages provide collateral for the security, the Fund may experience losses, costs and delays in enforcing its rights if the issuer defaults or enters bankruptcy.

Asset-Backed Securities

Asset-backed securities are interests in pools of debt securities backed by various types of loans such as credit card, auto and home equity loans. These securities involve prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining interest rates. During periods of rising interest rates, asset-backed securities have a high risk of declining in price because the declining prepayment rates effectively lengthen the

8

expected maturity of the securities. A decline in interest rates may lead to a faster rate of repayment on asset-backed securities and, therefore, cause a Fund to earn a lower interest rate on reinvestment. In addition, the potential impact of prepayment on the price of an asset-backed security may be difficult to predict and result in greater volatility.

CUSTODY RECEIPTS AND TRUST CERTIFICATES. Custody receipts, such as Morgan Stanley TRACERs (Traded Custody Receipts), and trust certificates, such as Lehman Brothers TRAINs (Targeted Return Index Securities Trust), are derivative products which, in the aggregate, evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing those securities or with a trust in exchange for trust certificates evidencing interests in the trust, the principal asset of which is those securities. The sponsor will then generally sell those custody receipts or trust certificates in negotiated transactions at varying prices that are determined at the time of sale. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities. Each holder of a custody receipt or trust certificate generally will be treated as directly purchasing its pro rata share of the securities in the pool for an amount equal to the amount that such holder paid for its custody receipt or trust certificate. If a custody receipt or trust certificate is sold, a holder will be treated as having directly "disposed of its pro rata share of the securities evidenced by the custody receipt or trust certificate. Additionally, the holder of a custody receipt or trust certificate may withdraw the securities represented by the custody receipt or trust certificate subject to certain conditions. Custody receipts and trust certificates are generally subject to the same risks as those securities evidenced by the receipts or certificates which, in the case of the Fund, are corporate debt securities. Additionally, custody receipts and trust certificates may also be less liquid than the underlying securities if the sponsor fails to maintain a trading market.

REPURCHASE AGREEMENTS

The Fund may enter into repurchase agreements. A repurchase agreement is a contract under which the Fund acquires a security for a relatively short period subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). It is the Fund's present intention to enter into repurchase agreements only with commercial banks and registered broker-dealers and only with respect to obligations of the U.S. government or its agencies or instrumentalities. Repurchase agreements may also be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Advisor will monitor such transactions to determine that the value of the underlying securities is at least equal at all times to the total amount of the repurchase obligation, including the interest factor. If the seller defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of sale including accrued interest are less than the resale price provided in the agreement including interest. In addition, if the seller should be involved in bankruptcy or insolvency proceedings, the Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the Fund is treated as an unsecured creditor and required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase agreement, the Fund sells a security and agrees to repurchase the same security at a mutually agreed upon date and price. A reverse repurchase agreement may also be viewed as the borrowing of money by the Fund and, therefore, as a form of leverage. The Fund will invest the proceeds of borrowings under reverse repurchase agreements. In addition, the Fund will enter into a reverse repurchase agreement only when the interest income expected to be earned from the investment of the proceeds is greater than the interest expense of the transaction. The Fund will not invest the proceeds of a reverse repurchase agreement for a period which exceeds the duration of the reverse repurchase agreement. The Fund may not enter into reverse repurchase agreements exceeding in the aggregate one-third of the market value of its total assets, less liabilities other than the obligations created by reverse repurchase agreements. Each Fund will establish and maintain with its custodian a separate account with a segregated portfolio of securities in an amount at least equal to its purchase obligations under its reverse repurchase agreements. If interest rates rise during the term of a reverse repurchase agreement, entering into the reverse repurchase agreement may have a negative impact on a money market fund's ability to maintain a net asset value of $1.00 per share.

LINE OF CREDIT

The Fund may establish and maintain a line of credit with a major bank in order to permit borrowing on a temporary basis to meet share redemption requests in circumstances in which temporary borrowings may be preferable to liquidation of portfolio securities.

OPTIONS ON SECURITIES

9

WRITING COVERED OPTIONS. The Fund may write covered call options and covered put options on securities held in its portfolio when, in the opinion of the Advisor, such transactions are consistent with the Fund's investment goal and policies. Call options written by the Fund give the purchaser the right to buy the underlying securities from the Fund at a stated exercise price; put options give the purchaser the right to sell the underlying securities to the Fund at a stated price.

The Fund may write only covered options, which means that, so long as the Fund is obligated as the writer of a call option, it will own the underlying securities subject to the option (or comparable securities satisfying the cover requirements of securities exchanges). In the case of put options, the Fund will hold cash and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, the Fund will be considered to have covered a put or call option if and to the extent that it holds an option that offsets some or all of the risk of the option it has written. The Fund may write combinations of covered puts and calls on the same underlying security.

The Fund will receive a premium from writing a put or call option, which increases the Fund's return on the underlying security if the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option but continues to bear the risk of a decline in the value of the underlying security. By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund may terminate an option that it has written prior to its expiration by entering into a closing purchase transaction in which it purchases an offsetting option. The Fund realizes a profit or loss from a closing transaction if the cost of the transaction (option premium plus transaction costs) is less or more than the premium received from writing the option. Because increases in the market price of a call option generally reflect increases in the market price of the security underlying the option, any loss resulting from a closing purchase transaction may be offset in whole or in part by unrealized appreciation of the underlying security.

If the Fund writes a call option but does not own the underlying security, and when it writes a put option, the Fund may be required to deposit cash or securities with its broker as "margin" or collateral for its obligation to buy or sell the underlying security. As the value of the underlying security varies, the Fund may have to deposit additional margin with the broker. Margin requirements are complex and are fixed by individual brokers, subject to minimum requirements currently imposed by the Federal Reserve Board and by stock exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS. The Fund may purchase put options to protect its portfolio holdings in an underlying security against a decline in market value. Such hedge protection is provided during the life of the put option since the Fund, as holder of the put option, is able to sell the underlying security at the put exercise price regardless of any decline in the underlying security's market price. For a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs. By using put options in this manner, the Fund will reduce any profit it might otherwise have realized from appreciation of the underlying security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS. The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

OVER-THE-COUNTER (OTC) OPTIONS. The Staff of the Division of Investment Management of the Securities and Exchange Commission (SEC) has taken the position that OTC options purchased by the Fund and assets held to cover OTC options written by the Fund are illiquid securities. Although the Staff has indicated that it is continuing to evaluate this issue, pending further developments, the Fund intends to enter into OTC options transactions only with primary dealers in U.S. government securities and, in the case of OTC options written by the Fund, only pursuant to agreements that will assure that the Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. The Fund will treat the amount

10

by which such formula price exceeds the amount, if any, by which the option may be "in-the-money" as an illiquid investment. It is the present policy of the Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund's Prospectus) of the Fund's net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by the Fund, (ii) OTC options purchased by the Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

RISK FACTORS IN OPTIONS TRANSACTIONS. The successful use of the Fund's options strategies depends on the ability of the Advisor to forecast interest rate and market movements correctly.

When it purchases an option, the Fund runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction with respect to the option during the life of the option. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying securities, since the Fund may continue to hold its investment in those securities notwithstanding the lack of a change in price of those securities.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Advisor deems it desirable to do so. Although the Fund will take an option position only if the Advisor believes there is a liquid secondary market for the option, there is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary trading market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A marketplace may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events -- such as volume in excess of trading or clearing capability -- were to interrupt normal market operations.

A marketplace may at times find it necessary to impose restrictions on particular types of option transactions, which may limit the Fund's ability to realize its profits or limit its losses.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation (OCC) or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If a prohibition on exercise remains in effect until an option owned by the Fund has expired, the Fund could lose the entire value of its option.

Special risks are presented by internationally traded options. Because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS

Upon entering into futures contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated with the Fund's custodian..

A futures contract sale creates an obligation by the seller to deliver the type of instrument called for in the contract in a specified delivery month for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of instrument called for in the contract in a specified delivery month at a stated price. The specific instruments delivered or taken at the settlement date are not determined until on or near that date. The determination is made in accordance with the rules of the exchanges on which the futures contract was made. The Fund may enter into futures contracts which are traded on national or foreign futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges

11

and trading in the United States are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC).

Although futures contracts by their terms call for actual delivery or acceptance of commodities or securities, the contracts usually are closed out before the settlement date without the making or taking of delivery. Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If the price of the initial sale of the futures contract exceeds the price of the offsetting purchase, the seller is paid the difference and realizes a gain. Conversely, if the price of the offsetting purchase exceeds the price of the initial sale, the seller realizes a loss. Similarly, the closing out of a futures contract purchase is effected by the purchaser's entering into a futures contract sale. If the offsetting sale price exceeds the purchase price, the purchaser realizes a gain, and if the purchase price exceeds the offsetting sale price, the purchaser realizes a loss.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract, although the Fund is required to deposit with its custodian in a segregated account in the name of the futures broker an amount of cash and/or U.S. government securities. This amount is known as "initial margin." The nature of initial margin in futures transactions is different from that of margin in security transactions in that futures contract margin does not involve the borrowing of funds by the Fund to finance the transactions. Rather, initial margin is in the nature of a performance bond or good faith deposit on the contract that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Futures contracts also involve brokerage costs.

Subsequent payments, called "variation margin," to and from the broker (or the custodian) are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking to market."

The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of making such a move would be to reduce or eliminate the hedge position then currently held by the Fund. The Fund may close its positions by taking opposite positions which will operate to terminate the Fund's position in the futures contracts. Final determinations of variation margin are then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a loss or a gain. Such closing transactions involve additional commission costs.

INTEREST RATE FUTURES CONTRACTS. Bond prices are established in both the cash market and the futures market. In the cash market, bonds are purchased and sold with payment for the full purchase price of the bond being made in cash, generally within five business days after the trade. In the futures market, only a contract is made to purchase or sell a bond in the future for a set price on a certain date. Historically, the prices for bonds established in the futures markets have tended to move generally in the aggregate in concert with the cash market prices and have maintained fairly predictable relationships. Accordingly, the Funds may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Funds presently could accomplish a similar result to that which they hope to achieve through the use of futures contracts by selling bonds with long maturities and investing in bonds with short maturities when interest rates are expected to increase, or conversely, selling short-term bonds and investing in long-term bonds when interest rates are expected to decline. However, because of the liquidity that is often available in the futures market, the protection is more likely to be achieved, perhaps at a lower cost and without changing the rate of interest being earned by the Funds, through using futures contracts.

Interest rate futures contracts are traded in an auction environment on the floors of several exchanges -- principally, the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The Funds would deal only in standardized contracts on recognized exchanges. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership.

A public market now exists in futures contracts covering various financial instruments including long-term United States Treasury Bonds and Notes; Government National Mortgage Association (GNMA) modified pass-through mortgage backed securities; three-month United States Treasury Bills; and ninety-day commercial paper. The Funds may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

MUNICIPAL BOND INDEX FUTURES CONTRACTS. Municipal bond index futures contracts may act as a hedge against changes in market conditions. A municipal bond index assigns values daily to the municipal bonds included in the index based on the independent assessment of dealer-to-dealer municipal bond brokers. A municipal bond index futures contract represents a firm

12

commitment by which two parties agree to take or make delivery of an amount equal to a specified dollar amount multiplied by the difference between the municipal bond index value on the last trading date of the contract and the price at which the futures contract is originally struck. No physical delivery of the underlying securities in the index is made.

The Chicago Board of Trade has designed a futures contract based on the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue and general obligation bonds, and its composition is updated regularly as new bonds meeting the criteria of the Index are issued and existing bonds mature. The Index is intended to provide an accurate indicator of trends and changes in the municipal bond market. Each bond in the Index is independently priced by six dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged and multiplied by a coefficient. The coefficient is used to maintain the continuity of the Index when its composition changes. The Chicago Board of Trade, on which futures contracts based on this Index are traded, as well as other U.S. commodities exchanges, are regulated by the CFTC. Transactions on such exchange are cleared through a clearing corporation, which guarantees the performance of the parties to each contract.

OPTIONS ON FUTURES CONTRACTS. The Fund will enter into written options on futures contracts only when, in compliance with the SEC's requirements, cash or liquid securities equal in value to the commodity value (less any applicable margin deposits) have been deposited in a segregated account. The Fund may purchase and write call and put options on futures contracts it may buy or sell and enter into closing transactions with respect to such options to terminate existing positions. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or purchasing and selling the underlying futures contracts. Such options generally operate in the same manner as options purchased or written directly on the underlying investments.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. Successful use of futures contracts by the Fund is subject to the Advisor's ability to predict correctly, movements in the direction of interest rates and other factors affecting securities markets.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution, by exchanges, of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a hedge position held by the Fund, the Fund may seek to close out a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

USE BY TAX-EXEMPT FUNDS OF INTEREST RATE AND U.S. TREASURY SECURITY FUTURES CONTRACTS AND OPTIONS. The Funds investing in tax-exempt securities may purchase and sell futures contracts and related options on interest rate and U.S. Treasury securities when, in the opinion of the Advisor, price movements in these security futures and related options will correlate closely with price movements in the tax-exempt securities which are the subject of the hedge. Interest rate and U.S. Treasury securities futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of security called for in the contract at a specified date and price. Options on interest rate and U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a futures contract at the specified option exercise price at any time during the period of the option.

In addition to the risks generally involved in using futures contracts, there is also a risk that price movements in interest rate and U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for tax-exempt securities.

INDEX FUTURES CONTRACTS. An index futures contract is a contract to buy or sell units of an index at a specified future date at a price agreed upon when the contract is made. Entering into a contract to buy units of an index is commonly referred to as buying or purchasing a contract or holding a long position in the index. Entering into a contract to sell units of an index is commonly referred to as selling a contract or holding a short position. A unit is the current value of the index. The Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s). The Fund may also purchase and sell options on index futures contracts.

There are several risks in connection with the use by the Fund of index futures as a hedging device. One risk arises because of the imperfect correlation between movements in the prices of the index futures and movements in the prices of securities which are the subject of the hedge. The Advisor will attempt to reduce this risk by selling, to the extent possible, futures on indices the movements of which will, in its judgment, have a significant correlation with movements in the prices of the Fund's portfolio securities sought to be hedged.

Successful use of index futures by the Fund for hedging purposes is also subject to the Advisor's ability to predict correctly movements in the direction of the market. It is possible that, where the Fund has sold futures to hedge its portfolio against a decline in the market, the index on which the futures are written may advance and the value of securities held in the Fund's portfolio may decline. If this occurs, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities. However, while this could occur to a certain degree, the Advisor believes that over time the value of the Fund's portfolio will tend to move in the same direction as the market indices which are intended to correlate to the price movements of the portfolio securities sought to be hedged. It is also possible that, if the Fund has hedged against the possibility of a decline in the market adversely affecting securities held in its portfolio and securities prices increase instead, the Fund will lose part or all of the benefit of the increased values of those securities that it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements.

In addition to the possibility that there may be an imperfect correlation, or no correlation at all, between movements in the index futures and the securities of the portfolio being hedged, the prices of index futures may not correlate perfectly with movements in the underlying index due to certain market distortions. First, all participants in the futures markets are subject to margin deposit and maintenance requirements. Rather than meeting additional margin deposit requirements, investors may close futures contracts through offsetting transactions which would distort the normal relationship between the index and futures markets. Second, margin requirements in the futures market are less onerous than margin requirements in the securities market, and as a result, the futures market may attract more speculators than the securities market. Increased participation by speculators in the futures market may also cause temporary price distortions. Due to the possibility of price distortions in the futures market and also because of the imperfect correlation between movements in the index and movements in the prices of index futures, even a correct forecast of general market trends by the Advisor may still not result in a successful hedging transaction.

OPTIONS ON INDEX FUTURES. Options on index futures are similar to options on securities except that options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration

14

date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

OPTIONS ON INDICES. As an alternative to purchasing call and put options on index futures, the Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the Options Clearing Corporation. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

OPTIONS ON FOREIGN STOCK INDICES. The Funds may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges. A stock index fluctuates with changes in the market values of the stocks included in the index.

SWAP AGREEMENTS (SWAPS, CAPS, COLLARS AND FLOORS)

The Funds may enter into interest rate swaps, currency swaps, and other types of swap agreements such as caps, collars, and floors. In a typical interest rate swap, one party agrees to make regular payments equal to a floating interest rate times a "notional principal amount," in return for payments equal to a fixed rate times the same amount, for a specified period of time. If a swap agreement provides for payments in different currencies, the parties might agree to exchange notional principal amount as well. Swaps may also depend on other prices or rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of investment to another. For example, if a Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund's exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a Fund's investments and its share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Funds' performance. Swap agreements are subject to risks related to the counterparty's ability to perform, and may decline in value if the counterparty's creditworthiness deteriorates. The Funds may also suffer losses if they are unable to terminate outstanding swap agreements or reduce their exposure through offsetting transactions.

Equity Swaps

The Fund may engage in equity swaps. Equity swaps allow the parties to the swap agreement to exchange components of return on one equity investment (e.g., a basket of equity securities or an index) for a component of return on another non-equity or equity investment, including an exchange of differential rates of return. Equity swaps may be used to invest in a market without owning or taking physical custody of securities in circumstances where direct investment may be restricted for legal reasons or is otherwise impractical. Equity swaps also may be used for other purposes, such as hedging or seeking to increase total return.

RISK FACTORS IN EQUITY SWAP TRANSACTIONS. Equity swaps are derivative instruments and their values can be very volatile. To the extent that the portfolio managers do not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults. See "Taxes" for information on tax risks associated with equity swaps.

15

FOREIGN CURRENCY TRANSACTIONS

The Fund may engage in currency exchange transactions to protect against uncertainty in the level of future currency exchange rates.

The Fund may engage in both "transaction hedging" and "position hedging." When it engages in transaction hedging, the Fund enters into foreign currency transactions with respect to specific receivables or payables of the Fund generally arising in connection with the purchase or sale of its portfolio securities. The Fund will engage in transaction hedging when it desires to "lock in" the U.S. dollar price of a security it has agreed to purchase or sell, or the U.S. dollar equivalent of a dividend or interest payment in a foreign currency. By transaction hedging the Fund attempts to protect itself against a possible loss resulting from an adverse change in the relationship between the U.S. dollar and the applicable foreign currency during the period between the date on which the security is purchased or sold, or on which the dividend or interest payment is declared, and the date on which such payments are made or received.

The Fund may purchase or sell a foreign currency on a spot (or cash) basis at the prevailing spot rate in connection with the settlement of transactions in portfolio securities denominated in that foreign currency. The Fund may also enter into contracts to purchase or sell foreign currencies at a future date ("forward contracts") and purchase and sell foreign currency futures contracts.

For transaction hedging purposes the Fund may also purchase exchange-listed and over-the-counter call and put options on foreign currency futures contracts and on foreign currencies. Over-the-counter options are considered to be illiquid by the SEC staff. A put option on a futures contract gives the Fund the right to assume a short position in the futures contract until expiration of the option. A put option on currency gives the Fund the right to sell a currency at an exercise price until the expiration of the option. A call option on a futures contract gives the Fund the right to assume a long position in the futures contract until the expiration of the option. A call option on currency gives the Fund the right to purchase a currency at the exercise price until the expiration of the option.

When it engages in position hedging, the Fund enters into foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which its portfolio securities are denominated (or an increase in the value of currency for securities which the Fund expects to purchase, when the Fund holds cash or short-term investments). In connection with position hedging, the Fund may purchase put or call options on foreign currency and foreign currency futures contracts and buy or sell forward contracts and foreign currency futures contracts. The Fund may also purchase or sell foreign currency on a spot basis.

The precise matching of the amounts of foreign currency exchange transactions and the value of the portfolio securities involved will not generally be possible since the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the dates the currency exchange transactions are entered into and the dates they mature.

It is impossible to forecast with precision the market value of portfolio securities at the expiration or maturity of a forward or futures contract. Accordingly, it may be necessary for the Fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security or securities being hedged is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security or securities and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security or securities if the market value of such security or securities exceeds the amount of foreign currency the Fund is obligated to deliver.

Transaction and position hedging do not eliminate fluctuations in the underlying prices of the securities which the Fund owns or intends to purchase or sell. They simply establish a rate of exchange which one can achieve at some future point in time. Additionally, although these techniques tend to minimize the risk of loss due to a decline in the value of the hedged currency, they tend to limit any potential gain which might result from the increase in value of such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS. Upon entering into such contracts, in compliance with the SEC's requirements, cash or liquid securities, equal in value to the amount of the Fund's obligation under the contract (less any applicable margin deposits and any assets that constitute "cover" for such obligation), will be segregated.

A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties, at a price set at the time of the contract. In the case of a

16

cancelable contract, the holder has the unilateral right to cancel the contract at maturity by paying a specified fee. The contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A contract generally has no deposit requirement, and no commissions are charged at any stage for trades. A currency futures contract is a standardized contract for the future delivery of a specified amount of a foreign currency at a future date at a price set at the time of the contract. Currency futures contracts traded in the United States are designed and traded on exchanges regulated by the CFTC, such as the New York Mercantile Exchange.

Forward currency contracts differ from currency futures contracts in certain respects. For example, the maturity date of a forward contract may be any fixed number of days from the date of the contract agreed upon by the parties, rather than a predetermined date in a given month. Forward contracts may be in any amounts agreed upon by the parties rather than predetermined amounts. Also, forward contracts are traded directly between currency traders so that no intermediary is required. A forward contract generally requires no margin or other deposit.

At the maturity of a forward or futures contract, the Fund may either accept or make delivery of the currency specified in the contract, or at or prior to maturity enter into a closing transaction involving the purchase or sale of an offsetting contract. Closing transactions with respect to forward contracts are usually effected with the currency trader who is a party to the original forward contract. Closing transactions with respect to futures contracts are effected on a commodities exchange; a clearing corporation associated with the exchange assumes responsibility for closing out such contracts.

Positions in currency futures contracts may be closed out only on an exchange or board of trade which provides a secondary market in such contracts. Although the Fund intends to purchase or sell currency futures contracts only on exchanges or boards of trade where there appears to be an active secondary market, there is no assurance that a secondary market on an exchange or board of trade will exist for any particular contract or at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make daily cash payments of variation margin.

CURRENCY OPTIONS. In general, options on currencies operate similarly to options on securities and are subject to many similar risks. Currency options are traded primarily in the over-the-counter market, although options on currencies have recently been listed on several exchanges. Options are traded not only on the currencies of individual nations, but also on the European Currency Unit (ECU). The ECU is composed of amounts of a number of currencies, and is the official medium of exchange of the European Economic Community's European Monetary System.

The Fund will only purchase or write currency options when the Advisor believes that a liquid secondary market exists for such options. There can be no assurance that a liquid secondary market will exist for a particular option at any specified time. Currency options are affected by all of those factors which influence exchange rates and investments generally. To the extent that these options are traded over the counter, they are considered to be illiquid by the SEC staff.

The value of any currency, including the U.S. dollar, may be affected by complex political and economic factors applicable to the issuing country. In addition, the exchange rates of currencies (and therefore the values of currency options) may be significantly affected, fixed, or supported directly or indirectly by government actions. Government intervention may increase risks involved in purchasing or selling currency options, since exchange rates may not be free to fluctuate in respect to other market forces.

The value of a currency option reflects the value of an exchange rate, which in turn reflects relative values of two currencies, the U.S. dollar and the foreign currency in question. Because currency transactions occurring in the interbank market involve substantially larger amounts than those that may be involved in the exercise of currency options, investors may be disadvantaged by having to deal in an odd lot market for the underlying currencies in connection with options at prices that are less favorable than for round lots. Foreign governmental restrictions or taxes could result in adverse changes in the cost of acquiring or disposing of currencies.

There is no systematic reporting of last sale information for currencies and there is no regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Available quotation information is generally representative of very large round-lot transactions in the interbank market and thus may not reflect exchange rates for smaller odd-lot transactions (less than $1 million) where rates may be less favorable. The interbank market in currencies is a global, around-the-clock market. To the extent that options markets are closed while the markets for the underlying currencies remain open, significant price and rate movements may take place in the underlying markets that cannot be reflected in the options markets.

17

SETTLEMENT PROCEDURES. Settlement procedures relating to the Fund's investments in foreign securities and to the Fund's foreign currency exchange transactions may be more complex than settlements with respect to investments in debt or equity securities of U.S. issuers, and may involve certain risks not present in the Fund's domestic investments, including foreign currency risks and local custom and usage. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION. Although foreign exchange dealers do not charge a fee for currency conversion, they do realize a profit based on the difference (spread) between prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer. Foreign currency transactions may also involve the risk that an entity involved in the settlement may not meet its obligation.

PARTICIPATION INTERESTS

The Fund may invest in municipal obligations either by purchasing them directly or by purchasing certificates of accrual or similar instruments evidencing direct ownership of interest payments or principal payments, or both, on municipal obligations, provided that, in the opinion of counsel to the initial seller of each such certificate or instrument, any discount accruing on such certificate or instrument that is purchased at a yield not greater than the coupon rate of interest on the related municipal obligations will be exempt from federal income tax to the same extent as interest on such municipal obligations. The Fund may also invest in tax-exempt obligations by purchasing from banks participation interests in all or part of specific holdings of municipal obligations. Such participations may be backed in whole or part by an irrevocable letter of credit or guarantee of the selling bank. The selling bank may receive a fee from the Fund in connection with the arrangement. The Fund will not purchase such participation interests unless it receives an opinion of counsel or a ruling of the Internal Revenue Service that interest earned by it on municipal obligations in which it holds such participation interests is exempt from federal income tax.

STAND-BY COMMITMENTS

When the Fund purchases municipal obligations, it may also acquire stand-by commitments from banks and broker-dealers with respect to such municipal obligations. A stand-by commitment is the equivalent of a put option acquired by the Fund with respect to a particular municipal obligation held in its portfolio. A stand-by commitment is a security independent of the municipal obligation to which it relates. The amount payable by a bank or dealer during the time a stand-by commitment is exercisable, absent unusual circumstances relating to a change in market value, would be substantially the same as the value of the underlying municipal obligation. A stand-by commitment might not be transferable by the Fund, although it could sell the underlying municipal obligation to a third party at any time.

The Fund expects that stand-by commitments generally will be available without the payment of direct or indirect consideration. However, if necessary and advisable, the Fund may pay for stand-by commitments either separately in cash or by paying a higher price for portfolio securities which are acquired subject to such a commitment (thus reducing the yield to maturity otherwise available for the same securities). The total amount paid in either manner for outstanding stand-by commitments held in the Fund portfolio will not exceed 10% of the value of the Fund's total assets calculated immediately after each stand-by commitment is acquired. The Fund will enter into stand-by commitments only with banks and broker-dealers that, in the judgment of the Trust's Board of Trustees, present minimal credit risks.

VARIABLE AND FLOATING RATE OBLIGATIONS

Variable rate instruments provide for periodic adjustments in the interest rate. Floating rate instruments provide for automatic adjustment of the interest rate whenever some other specified interest rate changes. Some variable and floating rate obligations are direct lending arrangements between the purchaser and the issuer and there may be no active secondary market. However, in the case of variable and floating rate obligations with a demand feature, a Fund may demand payment of principal and accrued interest at a time specified in the instrument or may resell the instrument to a third party. In the event an issuer of a variable or floating rate obligation defaulted on its payment obligation, a Fund might be unable to dispose of the note because of the absence of a secondary market and could, for this or other reasons, suffer a loss to the extent of the default. Variable or floating rate instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities are similar in form but may have a more active secondary market. Substantial holdings of variable and floating rate instruments could reduce portfolio liquidity.

If a variable or floating rate instrument is not rated, the Fund's Advisor must determine that such instrument is comparable to rated instruments eligible for purchase by the Funds and will consider the earning power, cash flows and other liquidity ratios of

18

the issuers and guarantors of such instruments and will continuously monitor their financial status in order to meet payment on demand. In determining average weighted portfolio maturity of each of these Funds, a variable or floating rate instrument issued or guaranteed by the U.S. Government or an agency or instrumentality thereof will be deemed to have a maturity equal to the period remaining until the obligation's next interest rate adjustment. Variable and floating rate obligations with a demand feature will be deemed to have a maturity equal to the longer of the period remaining to the next interest rate adjustment or the demand notice period.

INVERSE FLOATERS

Inverse floaters are derivative securities whose interest rates vary inversely to changes in short-term interest rates and whose values fluctuate inversely to changes in long-term interest rates. The value of certain inverse floaters will fluctuate substantially more in response to a given change in long-term rates than would a traditional debt security. These securities have investment characteristics similar to leverage, in that interest rate changes have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

The Fund may purchase securities that have been privately placed but that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (1933 Act). That Rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities that have not been registered for sale under the 1933 Act. The Advisor, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's investment restriction on illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, the Advisor will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, the Advisor could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market, and (4) nature of the security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers, and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined by the Advisor that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not exceed its investment limit on illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

CURRENCY SWAPS. Currency swaps involve the exchange of rights to make or receive payments in specified currencies. Currency swaps usually involve the delivery of the entire principal value of one designated currency. Therefore, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations. The use of currency swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect in its forecast of market value and currency exchange rates, the investment performance of a Fund would be less favorable than it would have been if this investment technique were not used.

CONVERTIBLE SECURITIES

Convertible securities are fixed income securities which may be exchanged or converted into a predetermined number of shares of the issuer's underlying common stock at the option of the holder during a specified time period. Convertible securities may take the form of convertible preferred stock, convertible bonds or debentures, units consisting of "usable" bonds and warrants or a combination of the features of several of these securities.

Convertible bonds and convertible preferred stocks generally retain the investment characteristics of fixed income securities until they have been converted but also react to movements in the underlying equity securities. The holder is entitled to receive the fixed income of a bond or the dividend preference of a preferred stock until the holder elects to exercise the conversion privilege. Usable bonds are corporate bonds that can be used in whole or in part, customarily at full face value, in lieu of cash to purchase the issuer's common stock. When owned as part of a unit along with warrants, which are options to buy the common stock, they function as convertible bonds, except that the warrants generally will expire before the bond's maturity. Convertible securities are senior to equity securities and therefore have a claim to the assets of the issuer prior to the holders of common stock in the case of liquidation. However, convertible securities are generally subordinated to similar non-convertible securities of the same issuer. The interest income and dividends from convertible bonds and preferred stocks provide a stable stream of income with generally higher yields than common stocks, but lower than non-convertible securities of similar quality. A Fund will exchange or convert the convertible securities held in its portfolio into shares of the underlying common stock in instances in which, in the Advisor's opinion, the investment characteristics of the underlying common stock will assist the Fund in achieving its investment objective.

19

Otherwise, the Fund will hold or trade the convertible securities. In selecting convertible securities for a Fund, the Advisor evaluates the investment characteristics of the convertible security as a fixed income instrument, and the investment potential of the underlying equity security for capital appreciation.

GUARANTEED INVESTMENT CONTRACTS

Pursuant to guaranteed investment contracts ("GICs"), which are issued by U.S. and Canadian insurance companies, a Fund makes cash contributions to a deposit fund of the insurance company's general account. The insurance company then credits to the fund payments at negotiated, floating or fixed interest rates. A GIC is a general obligation of the issuing insurance company and not a separate account. The purchase price paid for a GIC becomes part of the general assets of the insurance company, and the contract is paid from the company's general assets.

The Funds will only purchase GICs that are issued or guaranteed by insurance companies that at the time of purchase are rated at least AA by S&P or receive a similar high quality rating from a nationally recognized service which provides ratings of insurance companies. GICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available. No Fund will invest more than 20% of its total assets in GICs.

BANK INVESTMENT CONTRACTS

Bank investment contracts ("BICs") issued by banks that meet certain quality and asset size requirements for banks are available to the Funds. Pursuant to BICs, cash contributions are made to a deposit account at the bank in exchange for payments at negotiated, floating or fixed interest rates. A BIC is a general obligation of the issuing bank. BICs are considered illiquid securities and will be subject to any limitations on such investments described in Part 1 of this SAI, unless there is an active and substantial secondary market for the particular instrument and market quotations are readily available.

LOAN PARTICIPATIONS

Loan participations are interests in loans which are administered by the lending bank or agent for a syndicate of lending banks, and sold by the lending bank or syndicate member. The Funds may only purchase interests in loan participations issued by a bank in the United States with assets exceeding $1 billion and for which the underlying loan is issued by borrowers in whose obligations the Funds may invest. Because the intermediary bank does not guarantee a loan participation in any way, a loan participation is subject to the credit risk generally associated with the underlying corporate borrower. In addition, in the event the underlying corporate borrower defaults, a Fund may be subject to delays, expenses and risks that are greater than those that would have been involved if the Fund had purchased a direct obligation (such as commercial paper) of the borrower. Under the terms of a loan participation, the purchasing Fund may be regarded as a creditor of the intermediary bank so that the Fund may also be subject to the risk that the issuing bank may become insolvent.

STRUCTURED INVESTMENTS

Structured investments are a relatively new innovation and may be designed to have various combinations of equity and fixed-income characteristics. Equity-linked securities are a form of structured investment and generally consist of a conversion privilege to a single company's common stock plus a fixed annual distribution to the holder. Equity-linked securities have some derivative characteristics because the conversion feature is linked to the price of the company's common stock. Equity-linked securities are designed to provide investors with higher quarterly income than the dividend paid per share on the common stock. However, equity-linked securities have decreased potential for capital appreciation because of limitations of the conversion feature.

Equity-linked securities include issues such as "Structured Yield Product Exchangeable for Stock" ("STRYPES"), "Trust Automatic Common Exchange Securities" ("TRACES"), "Trust Issued Mandatory Exchange Securities" ("TIMES"), "Trust Enhanced Dividend Securities" ("TRENDS") and other similar securities, including those which may be developed in the future. The issuers of the above listed examples of equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on equity-linked securities generally consist of the cash received from the U.S. Treasury securities and equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Equity-linked securities may be issued by closed-end or other forms of investment companies. To the extent that equity-linked securities are issued by investment companies, a Fund's investments in equity-linked securities are subject to the same limitations as investments in more traditional forms of investment companies.

20

YANKEE OBLIGATIONS

Yankee obligations are U.S. dollar-denominated instruments of foreign issuers that are either registered with the SEC or issued pursuant to Rule 144A under the 1933 Act. These obligations consist of debt securities (including preferred or preference stock of non-governmental issuers), certificates of deposit, fixed time deposits and banker's acceptances issued by foreign banks, and debt obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supranational entities. Some securities issued by foreign governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of the foreign government.

AMERICAN, EUROPEAN, CONTINENTAL AND GLOBAL DEPOSITARY RECEIPTS

American Depositary Receipts ("ADRs") are receipts issued in registered form by a U.S. bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. European Depositary Receipts ("EDRs"), which are sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts issued in Europe typically by non-U.S. banks or trust companies and foreign branches of U.S. banks that evidence ownership of foreign or U.S. securities. Global Depositary Receipts ("GDRs") are receipts structured similarly to EDRs and CDRs and are marketed globally. ADRs may be listed on a national securities exchange or may be traded in the over-the-counter market. EDRs and CDRs are designed for use in European exchange and over-the-counter markets. GDRs are designed for trading in non-U.S. securities markets. ADRs, EDRs, CDRs and GDRs traded in the over-the-counter market which do not have an active or substantial secondary market will be considered illiquid and therefore will be subject to the Funds' respective limitations with respect to such securities, if any. If a Fund invests in an unsponsored ADR, EDR, CDR or GDR, there may be less information available to the Fund concerning the issuer of the securities underlying the unsponsored ADR, EDR, CDR or GDR than is available for an issuer of securities underlying a sponsored ADR, EDR, CDR or GDR. ADR prices are denominated in U.S. dollars although the underlying securities are denominated in a foreign currency. Investments in ADRs, EDRs, CDRs and GDRs involve risks similar to those accompanying direct investments in foreign securities.

TEMPORARY CASH BALANCES

The Funds may hold very small temporary cash balances to efficiently manage transactional expenses. These cash balances are expected, under normal conditions, not to exceed 2% of each Fund's net assets at any time (excluding amounts used as margin and segregated assets with respect to futures transactions and collateral for securities loans and repurchase agreements). The Funds may invest these temporary cash balances in short-term debt obligations issued or guaranteed by the U.S. Government or its agencies and instrumentalities ("U.S. Government Securities"), high quality commercial paper (rated A-1 or better by S&P or P-1 or better by Moody's), certificates of deposit and time deposits of banking institutions having total assets in excess of $1 billion, and repurchase agreements collateralized by U.S. Government Securities. The Funds may also hold these investments in connection with U.S. Treasury rolls, which are not subject to the 2% limitation above.

TAXES

In this section, all discussions of taxation at the shareholder and fund levels relate to U.S. federal taxes only. Consult your tax advisor for state, local and foreign tax considerations and for information about special tax considerations that may apply to shareholders that are not natural persons or not U.S. citizens or resident aliens.

FEDERAL TAXES. Although it may be one of several series in a single trust, the Fund is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (Code). The Fund has elected (or in the case of a new fund, intends to elect) to be, and intends to qualify to be treated each year as, a "regulated investment company" under Subchapter M of the Code by meeting all applicable requirements of Subchapter M, including requirements as to the nature of the Fund's gross income, the amount of its distributions (as a percentage of both its overall income and any tax-exempt income), and the composition of its portfolio assets.

To qualify as a "regulated investment company," the Fund must (a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies or other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; (b) diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the market value of its total assets consists of cash, cash items, U.S. government securities, securities of other regulated investment companies and other securities limited generally with respect to any one issuer to not more than 5% of the total assets of the Fund and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any issuer, other than U.S. government securities

21

or other regulated investment companies; or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses; and (c) distribute with respect to each year at least 90% of its taxable net investment income, its tax-exempt interest income and the excess, if any, of net short-term capital gains over net long-term capital losses for such year. In general, for purposes of the 90% gross income requirement described in
(a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized by the regulated investment company. However, recent legislation, provides that for taxable years of a regulated investment company beginning after October 22, 2004, 100% of the net income derived from an interest in a "qualified publicly traded partnership" (defined as a partnership (i) interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof and (ii) that derives less than 90% of its income from the qualifying income described in (a) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do not apply to a regulated investment company with respect to items attributable to an interest in a qualified publicly traded partnership. Finally, for purposes of (c) above, the term "outstanding voting securities of such issuer" will include the equity securities of a qualified publicly traded partnership. As a regulated investment company that is accorded special tax treatment, the Fund will not be subject to any federal income taxes on its net investment income and net realized capital gains that it distributes to shareholders on the form of dividends and in accordance with the timing requirements imposed by the Code. The Fund's foreign-source income, if any, may be subject to foreign withholding taxes. If the Fund were to fail to qualify as a "regulated investment company" accorded special tax treatment in any taxable year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions (including any distributions of net tax-exempt income and net long-term capital gains) would generally be taxable as ordinary income to the shareholders, except to the extent they were treated as "qualified dividend income," as described below. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all of its ordinary income for such year and substantially all of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a 4% excise tax on the underdistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

ALTERNATIVE MINIMUM TAX. Distributions derived from interest that is exempt from regular federal income tax may subject corporate shareholders to or increase their liability under the federal corporate alternative minimum tax (AMT). A portion of such distributions may constitute a tax preference item for individual shareholders and may subject them to or increase their liability under the AMT.

DIVIDENDS RECEIVED DEDUCTIONS. Distributions will qualify for the corporate dividends received deduction only to the extent that dividends earned by the Fund qualify. Any such dividends may be, however, includable in adjusted current earnings for purposes of computing corporate federal AMT. The dividends received deduction for eligible dividends is subject to a holding period requirement.

RETURN OF CAPITAL DISTRIBUTIONS. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated "earning and profits" in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his or her shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces tax basis in shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of such shares. Dividends and distributions on a Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when a Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when a Fund's net asset value also reflects unrealized losses.

FUNDS THAT INVEST IN U.S. GOVERNMENT SECURITIES. Many states grant tax-free status to dividends paid to shareholders of mutual funds from interest income earned by the Fund from direct obligations of the U.S. government. Investments in mortgage-backed securities (including GNMA, FNMA and FHLMC Securities) and repurchase agreements collateralized by U.S. government securities do not qualify as direct federal obligations in most states. Shareholders should consult with their own tax

22

advisors about the applicability of state and local intangible property, income or other taxes to their Fund shares and distributions and redemption proceeds received from the Fund.

FUND DISTRIBUTIONS. Distributions from the Fund (other than qualified dividend income and exempt-interest dividends, as discussed below) will generally be taxable to shareholders as ordinary income to the extent derived from the Fund's investment income and net short-term gains. Distributions of long-term capital gains (that is, the excess of net gains from capital assets held for more than one year over net losses from capital assets held for not more than one year) will be taxable to shareholders as such, regardless of how long a shareholder has held shares in the Fund. In general, any distributions of net capital gains will be taxed to shareholders who are individuals at a maximum rate of 15% for taxable years beginning on or before December 31, 2008.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price of the shareholder paid). Distributions are taxable whether received in cash or in Fund shares.

QUALIFIED DIVIDEND INCOME. For taxable years beginning on or before December 31, 2008, "qualified dividend income" received by an individual will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund's shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. With respect to a Fund investing in bonds, the Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

In general, distributions of investment income properly designated by the Fund as derived from qualified dividend income may be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to his or her shares. If the aggregate qualified dividends received by a fund during any taxable year are 95% or more of its gross income, then 100% of the Fund's dividends (other than properly designated capital gain dividends) will be eligible to be treated as qualified dividend income. For this purpose, the only gain included in the term "gross income" is the excess of net short-term capital gain over net long-term capital loss.

DISTRIBUTIONS FROM TAX-EXEMPT FUNDS. Each tax-exempt Fund will have at least 50% of its total assets invested in tax-exempt bonds at the end of each quarter so that dividends from net interest income on tax-exempt bonds will be exempt from federal income tax when received by a shareholder (but may be taxable for federal alternative minimum tax purposes and for state and local tax purposes). The tax-exempt portion of dividends paid will be designated within 60 days after year-end based upon the ratio of net tax-exempt income to total net investment income earned during the year. That ratio may be substantially different from the ratio of net tax-exempt income to total net investment income earned during any particular portion of the year. Thus, a shareholder who holds shares for only a part of the year may be allocated more or less tax-exempt dividends than would be the case if the allocation were based on the ratio of net tax-exempt income to total net investment income actually earned while a shareholder.

Income from certain "private activity bonds" issued after August 7, 1986, is treated as a tax preference item for the AMT at the maximum rate of 28% for individuals and 20% for corporations. If the Fund invests in private activity bonds, shareholders may be subject to the AMT on that part of the distributions derived from interest income on such bonds. Interest on all tax-exempt bonds is included in corporate adjusted current earnings when computing the AMT applicable to corporations. Seventy-five percent of the excess of adjusted current earnings over the amount of income otherwise subject to the AMT is included in a corporation's alternative minimum taxable income.

23

Dividends derived from any investments other than tax-exempt bonds and any distributions of short-term capital gains are generally taxable to shareholders as ordinary income. Any distributions of long-term capital gains will in general be taxable to shareholders as long-term capital gains (generally subject to a maximum 15% tax rate for shareholders who are individuals) regardless of the length of time Fund shares are held by the shareholder.

A tax-exempt Fund may at times purchase tax-exempt securities at a discount and some or all of this discount may be included in the Fund's ordinary income which will be taxable when distributed. Any market discount recognized on a tax-exempt bond purchased after April 30, 1993, with a term at time of issue of more than one year is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below its "stated redemption price" (in the case of a bond with original issue discount, its "revised issue price").

Shareholders receiving social security and certain retirement benefits may be taxed on a portion of those benefits as a result of receiving tax-exempt income, including tax-exempt dividends from the Fund.

SPECIAL TAX RULES APPLICABLE TO TAX-EXEMPT FUNDS. In general, exempt-interest dividends, if any, attributable to interest received on certain private activity obligations and certain industrial development bonds will not be tax-exempt to any shareholders who are "substantial users" of the facilities financed by such obligations or bonds or who are "related persons" of such substantial users, as further defined in the Code. Income derived from the Fund's investments other than tax-exempt instruments may give rise to taxable income. The Fund's shares must be held for more than six months in order to avoid the disallowance of a capital loss on the sale of Fund shares to the extent of tax-exempt dividends paid during that period. Part or all of the interest on indebtedness, if any, incurred or continued by a shareholder to purchase or carry shares of the Fund paying exempt-interest dividends is not deductible. The portion of interest that is not deductible is equal to the total interest paid or accrued on the indebtedness, multiplied by the percentage of the Fund's total distributions (not including distributions from net long-term capital gains) paid to the shareholder that are exempt-interest dividends. Under rules used by the Internal Revenue Service to determine when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase of shares may be considered to have been made with borrowed funds even though such funds are not directly traceable to the purchase of shares.

SALES OF SHARES. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain realized upon a taxable disposition of shares generally will be treated as long-term capital gain if the shares have been held for more than one year. Otherwise the gain on the sale, exchange or redemption of Fund shares will be treated as short-term capital gain. In general, any loss realized upon a taxable disposition of shares will be treated as long-term loss if the shares have been held more than one year, and otherwise as short-term loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be disallowed for federal income tax purposes to the extent of any exempt-interest dividends received on such shares. In addition, any loss (not already disallowed as provided in the preceding sentence) realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, capital loss to the extent of any long-term capital gain distributions received by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if other shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Under Treasury regulations, if on a disposition of Fund shares a shareholder recognizes a loss of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder will likely have to file with the Internal Revenue Service a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. You are advised to consult with your tax advisor.

BACKUP WITHHOLDING. Certain distributions and redemptions may be subject to backup withholding for taxpayers who fail to furnish a correct taxpayer identification number, who have under-reported dividend or interest income, or who fail to certify to the Fund that the shareholder is a United States person and is not subject to the withholding. This number and certification may be provided by either a Form W-9 or the accompanying application. In certain instances, CMS may be notified by the Internal Revenue Service that a shareholder is subject to backup withholding. The backup withholding rate is 28% for amounts paid through 2010. The backup withholding rate will be 31% for amounts paid after December 31, 2010.

24

HEDGING TRANSACTIONS. If the Fund engages in hedging transactions, including hedging transactions in options, futures contracts and straddles, or other similar transactions, it will be subject to special tax rules (including constructive sale, mark-to-market, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will endeavor to make any available elections pertaining to such transactions in a manner believed to be in the best interests of the Fund and its shareholders.

SECURITIES ISSUED AT A DISCOUNT. The Fund's investment in debt securities issued at a discount and certain other obligations will (and investments in securities purchased at a discount may) require the Fund to accrue and distribute income not yet received. In such cases, the Fund may be required to sell assets (possibly at a time when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level.

FOREIGN CURRENCY-DENOMINATED SECURITIES AND RELATED HEDGING TRANSACTIONS. The Fund's transactions in foreign currencies, foreign currency-denominated debt securities, certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This may produce a difference between the Fund's book income and its taxable income possibly accelerating distributions or converting distributions of book income and gains to returns of capital for book purposes.

If more than 50% of the Fund's total assets at the end of its fiscal year are invested in stock or securities of foreign corporate issuers, the Fund may make an election permitting its shareholders to take a deduction or credit for federal income tax purposes for their pro rata portion of certain qualified foreign taxes paid by the Fund to foreign countries in respect of foreign securities the Fund has held for at least the minimum period specified in the Code. The Advisor will consider the value of the benefit to a typical shareholder, the cost to the Fund of compliance with the election, and incidental costs to shareholders in deciding whether to make the election. A shareholder's ability to claim such a foreign tax credit or deduction in respect of foreign taxes will be subject to certain limitations imposed by the Code, including a holding period requirement, as a result of which a shareholder may not get a full credit or deduction for the amount of foreign taxes so paid by the Fund. Shareholders who do not itemize on their federal income tax returns may claim a credit (but not a deduction) for such foreign taxes.

Investment by the Fund in "passive foreign investment companies" could subject the Fund to a U.S. federal income tax or other charge on the proceeds from the sale of its investment in such a company; however, this tax can be avoided by making an election to mark such investments to market annually or to treat the passive foreign investment company as a "qualified electing Fund." A "passive foreign investment company" is any foreign corporation: (i) 75 percent or more of the income of which for the taxable year is passive income, or (ii) the average percentage of the assets of which (generally by value, but by adjusted tax basis in certain cases) that produce or are held for the production of passive income is at least 50 percent. Generally, passive income for this purpose means dividends, interest (including income equivalent to interest), royalties, rents, annuities, the excess of gain over losses from certain property transactions and commodities transactions, and foreign currency gains. Passive income for this purpose does not include rents and royalties received by the foreign corporation from active business and certain income received from related persons.

NON-U.S. SHAREHOLDERS. Capital gain dividends will not be subject to withholding of federal income tax. In general, dividends (other than Capital Gain Dividends) paid by the Fund to a shareholder that is not a "U.S. person" within the meaning of the Code (such shareholder, a "foreign person") are subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, under the recent legislation, effective for taxable years of the Fund beginning after December 31, 2004 and before January 1, 2008, the Fund will not be required to withhold any amounts (i) with respect to distributions (other than distributions to a foreign person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the foreign person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or
(z) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign person and the foreign person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual foreign person, to the extent such distributions are properly designated by the Fund, and (ii) with respect to distributions (other than distributions to an individual foreign person who is present in the United States for a period or periods

25

aggregating 183 days or more during the year of the distribution) of net short-term capital gains in excess of net long-term capital losses, to the extent such distributions are properly designated by the Fund. The Fund has not determined whether it will make such designations.

If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Recent legislation modifies the tax treatment of distributions from the Fund that are paid to a foreign person and are attributable to gain from "U.S. real property interests" ("USRPIs"), which the Code defines to include direct holdings of U.S. real property and interests (other than solely as a creditor) in "U.S. real property holding corporations" such as REITs. The Code deems any corporation that holds (or held during the previous five-year period) USRPIs with a fair market value equal to 50% or more of the fair market value of the corporation's U.S. and foreign real property assets and other assets used or held for use in a trade or business to be a U.S. real property holding corporation; however, if any class of stock of a corporation is traded on an established securities market, stock of such class shall be treated as a USRPI only in the case of a person who holds more than 5% of such class of stock at any time during the previous five-year period. Under the legislation, which is generally effective for taxable years of RICs beginning after December 31, 2004 and which applies to dividends paid or deemed paid on or before December 31, 2007, distributions to foreign persons attributable to gains from the sale or exchange of USRPIs will give rise to an obligation for those foreign persons to file a U.S. tax return and pay tax, and may well be subject to withholding under future regulations.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares constitute USRPIs or (effective for taxable years of the Fund beginning on September 1, 2005) the Capital Gain Dividends are paid or deemed paid on or before December 31, 2007 and are attributable to gains from the sale or exchange of USRPIs. Effective after December 31, 2004, and before January 1, 2008, if the Fund is a U.S. real property holding corporation (as described above) the Fund's shares will nevertheless not constitute USRPIs if the Fund is a "domestically controlled qualified investment entity," which is defined to include a RIC that, at all times during the shorter of the 5-year period ending on the date of the disposition or the period during which the RIC was in existence, had less than 50 percent in value of its stock held directly or indirectly by foreign persons.

ADDITIONAL TAX MATTERS CONCERNING TRUST SHARES (THIS SECTION IS APPLICABLE ONLY TO THE COLUMBIA TAX-MANAGED GROWTH FUND)

FEDERAL GIFT TAXES. An investment in Trust Shares may be a taxable gift for federal tax purposes, depending upon the option selected and other gifts that the donor and his or her spouse may make during the year.

Under the Columbia Advantage Plan, the entire amount of the gift will be a "present interest" that qualifies for the federal gift tax annual exclusion. In that case, the donor will be required to file a federal gift tax return on account of this gift only if (i) the aggregate present interest gifts by the donor to the particular beneficiary (including the gift of Trust Shares) exceed $11,000 or (ii) the donor wishes to elect gift splitting on gifts with his or her spouse for the year. The trustee will notify the beneficiary of his or her right of withdrawal promptly following any contribution under the Advantage Plan.

Under the Columbia Gift Plan, the entire amount of the gift will be a "future interest" for federal gift tax purposes, so that none of the gift will qualify for the federal gift tax annual exclusion. Consequently, the donor will have to file a federal gift tax return (IRS Form 709) reporting the entire amount of the gift, even if the gift is less than $11,000.

No federal gift tax will be payable by the donor until his or her cumulative taxable gifts (i.e., gifts other than those qualifying for the annual exclusion or otherwise exempt), including taxable gifts of other assets as well as any taxable gifts of trust shares, exceed the federal gift and estate tax exemption equivalent amount, which is $1,000,000 for gifts made after December 31, 2001, and before January 1, 2010.

26

Any gift of Trust Shares that does not qualify as a present interest or that exceeds the available annual exclusion amount will reduce the amount of the donor's Federal gift and estate tax exemption (if any) that would otherwise be available for future gifts for transfers at death.

The donor and his or her spouse may elect "gift-splitting" for any gift of Trust Shares (other than a gift to such spouse), meaning that the donor and his or her spouse may elect to treat the gift as having been made one-half by each of them, thus allowing a total gift of $22,000.

The donor's gift of Fund shares may also have to be reported for state gift tax purposes, if the state in which the donor resides imposes a gift tax. Many states do not impose such a tax. Some states follow the Federal rules concerning the types of transfers subject to tax and the availability of the annual exclusion.

GENERATION-SKIPPING TRANSFER TAXES

If the beneficiary of a gift of Trust Shares is a relative who is two generations or more younger than the donor, or is not a relative and is more than 37 1/2 years younger than the donor, the gift will be subject in whole or in part to the generation-skipping transfer tax (the "GST tax") unless the gift is made under the Columbia Advantage Plan and does not exceed the available annual exclusion amount. An exemption (the "GST exemption"), equal to $1.5 million in 2005, is allowed against this tax, and so long as the GST exemption has not been used by other transfers it will automatically be allocated to a gift of Trust Shares that is subject to the GST tax unless the donor elects otherwise. Such an election is made by reporting the gift on a timely filed gift tax return and paying the applicable GST tax. The GST tax is imposed at a flat rate (47% for gifts made in 2005) on the amount of the gift, and payment of the tax by the donor is treated as an additional gift for gift tax purposes.

INCOME TAXES

The Internal Revenue Service takes the position that a trust beneficiary who is given a power of withdrawal over contributions to the trust should be treated, for Federal income tax purposes, as the "owner" of the portion of the trust that was subject to the power. Accordingly, if the donor selects Columbia Advantage Trust Shares, the beneficiary will be treated as the "owner" of all of the Fund shares in the account for Federal income tax purposes, and will be required to report all of the income and capital gains earned in the trust on his or her personal Federal income tax return. The trust will not pay Federal income taxes on any of the trust's income or capital gains. The trustee will prepare and file the Federal income tax information returns that are required each year (and any state income tax returns that may be required), and will send the beneficiary a statement following each year showing the amounts (if any) that the beneficiary must report on his or her income tax returns for that year. If the beneficiary is under fourteen years of age, these amounts may be subject to Federal income taxation at the marginal rate applicable to the beneficiary's parents. The beneficiary may at any time after the creation of the trust irrevocably elect to require the trustee to pay him or her a portion of the trust's income and capital gains annually thereafter to provide funds with which to pay any resulting income taxes, which the trustee will do by redeeming Trust Shares. The amount distributed will be a fraction of the trust's ordinary income and short-term capital gains and the trust's long-term capital gains equal to the highest marginal Federal income tax rate imposed on each type of income (currently, 35% and 15%, respectively). If the beneficiary selects this option, he or she will receive those fractions of his or her trust's income and capital gains annually for the duration of the trust.

Under the Columbia Advantage Plan, the beneficiary will also be able to require the trustee to pay his or her tuition, room and board and other expense of his or her college or post-graduate education, and the trustee will raise the cash necessary to fund these distributions by redeeming Trust Shares. Any such redemption will result in the realization of capital gain or loss on the shares redeemed, which will be reportable by the beneficiary on his or her income tax returns for the year in which the shares are redeemed, as described above. Payments must be made directly to the educational institution.

If the donor selects the Columbia Gift Plan, the trust that he or she creates will be subject to Federal income tax on all income and capital gains realized by it, less a $100 annual exemption (in lieu of the personal exemption allowed to individuals). The amount of the tax will be determined under the tax rate schedule applicable to estates and trusts, which is more sharply graduated than the rate schedule for individuals, reaching the same maximum marginal rate for ordinary income or short-term capital gains (currently, 35%), but at a much lower taxable income level than would apply to an individual. It is anticipated, however, that most of the gains taxable to the trust will be long-term capital gain, on which the Federal income tax rate is currently limited to 15%. The trustee will raise the cash necessary to pay any Federal or state income taxes by redeeming Fund shares. The beneficiary will not pay Federal income taxes on any of the trust's income or capital gains, except those earned in the year when the trust terminates. The trustee will prepare and file all Federal and state income tax returns that are required

27

each year, and will send the beneficiary an information statement for the year in which the trust terminates showing the amounts (if any) that the beneficiary must report on his or her Federal and state income tax returns for that year.

When the trust terminates, the distribution of the remaining shares held in the trust to the beneficiary will not be treated as a taxable disposition of the shares. Any Fund shares received by the beneficiary will have the same cost basis as they had in the trust at the time of termination. Any Fund shares received by the beneficiary's estate will have a basis equal to the value of the shares at the beneficiary's death (or the alternate valuation date for Federal estate tax purposes, if elected).

Consultation with Qualified Advisor

Due to the complexity of Federal and state gift, GST and income tax laws pertaining to all gifts in trust, prospective donors should consider consulting with their financial or tax advisor before investing in Trust Shares.

MANAGEMENT OF THE FUNDS Columbia Management Advisors, LLC ("Columbia Advisors" or "CMA" or the "Advisor"), located at 100 Federal Street, Boston, Massachusetts 02110 is the Advisor to the Funds. The Advisor provides administrative and management services to the Funds. Columbia Advisors is a direct, wholly owned subsidiary of Columbia Management Group, LLC ("CMG"), which in turn is a direct, wholly owned subsidiary of Bank of America, which in turn is a wholly owned banking subsidiary of Bank of America Corporation, a financial services holding company organized as a Delaware corporation. On September 30, 2005, Columbia Management Advisors, Inc. ("Columbia Management") merged into Columbia Advisors (which prior to September 30, 2005 had been known as Banc of America Capital Management, LLC). Before September 30, 2005 Columbia Management was the investment advisor to the Funds. As a result of the merger, Columbia Advisors is now the investment advisor to the Funds. Columbia Advisors, a registered investment advisor, has been an investment advisor since 1995.

Trustee Positions

As of December 31, 2004, no disinterested Trustee or any of their immediate family members owned beneficially or of record any class of securities of the Advisor, another investment advisor, sub-advisor or portfolio manager of any of the funds in the Fund Complex or any person controlling, controlled by or under common control with any such entity.

Approving the Investment Advisory Contract

In determining to approve the most recent annual extension of a Fund's management agreement, the Trustees met over the course of the year with the relevant investment advisory personnel from the Advisor and considered information provided by the Advisor relating to the education, experience and number of investment professionals and other personnel providing services under that agreement. See "Managing the Fund" in each Fund's Prospectus and "Trustees and Officers" in this SAI. The Trustees also took into account the time and attention devoted by senior management to the Funds and the other funds in the Fund Complex. The Trustees evaluated the level of skill required to manage the Funds and concluded that the human resources devoted by the Advisor to the Funds were appropriate to fulfill effectively the Advisor's duties under the agreement. The Trustees also considered the business reputation of the Advisor and its financial resources, and concluded that the Advisor would be able to meet any reasonably foreseeable obligations under the agreement.

The Trustees received information concerning the investment philosophy and investment process applied by the Advisor in managing the Funds. See "Principal Investment Strategies" and "Principal Investment Risks" in the Funds' Prospectuses. In this connection, the Trustees considered the Advisor's in-house research capabilities as well as other resources available to the Advisor's personnel, including research services available to the Advisor as a result of securities transactions effected for the Funds and other investment advisory clients. The Trustees concluded that the Advisor's investment process, research capabilities and philosophy were well suited to each Fund, given each Fund's investment goal(s) and policies.

The Trustees considered the scope of the services provided by the Advisor to the Funds under the agreement relative to services provided by third parties to other mutual funds. See "Fund Charges and Expenses" and "Management of the Funds
- The Management Agreement". The Trustees concluded that the scope of the Advisor's services to the Funds was consistent with the Funds' operational requirements, including, in addition to its investment goal, compliance with each Fund's investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services provided by the Advisor to the Funds. The Trustees evaluated the Advisor's record with respect to regulatory compliance and compliance with the investment policies of each Fund. The Trustees also evaluated the procedures of the Advisor designed to fulfill the Advisor's fiduciary duty to the Funds with respect to possible conflicts of interest, including the Advisor's code of ethics (regulating the personal trading of its officers and employees) (see "Management of the Funds - Code of Ethics"), the procedures by which the Advisor allocates trades among its various investment advisory clients and the record of the Advisor in these matters. The Trustees also received information concerning standards of the Advisor with respect to the execution of portfolio transactions. See "Management of the Funds
- Portfolio Transactions."

The Trustees considered the Advisor's management of non-advisory services provided by persons other than the Advisor by reference, among other things, to each Fund's total expenses and the reputation of each Fund's other service providers. See "Your Expenses" in each Fund's Prospectus(es). The Trustees also considered information provided by third parties relating to each Fund's investment performance relative to its performance benchmark(s), relative to other similar funds managed by the Advisor and relative to funds managed similarly by other advisors. The Trustees reviewed performance over various periods, including each Fund's one, five and ten year calendar year periods and/or the life of the Fund, as applicable (See "Performance History" in the Fund's Prospectuses), as well as factors identified by the Advisor as contributing to each Fund's performance. See each Fund's most recent annual and semi-annual reports. The Trustees concluded that the scope and quality of the Advisor's services was sufficient to merit reapproval of the agreement for another year.

In reaching that conclusion, the Trustees also gave substantial consideration to the fees payable under the agreement. The Trustees reviewed information concerning fees paid to investment advisors of similarly-managed funds. The Trustees also considered the fees of the Funds as a percentage of assets at different asset levels and possible economies of scale to the Advisor. The Trustees evaluated the Advisor's profitability with respect to the Funds, concluding that such profitability appeared to be generally consistent with levels of profitability that had been determined by courts to be "not excessive." For these purposes, the Trustees took into account not only the actual dollar amount of fees paid by the Funds directly to the Advisor, but also so-called "fallout benefits" to the Advisor such as reputational value derived from serving as investment Advisor to the Funds and the research services available to the Advisor by reason of brokerage commissions generated by each Fund's turnover. In evaluating the Funds' advisory fees, the Trustees also took into account the complexity of investment management for the Funds relative to other types of funds. Based on challenges associated with less readily available market information about foreign issuers and smaller capitalization companies, limited liquidity of certain securities, and the specialization required for focused funds, the Trustees concluded that generally greater research intensity and trading acumen is required for equity funds, and for international or global funds, as compared to funds investing, respectively, in debt obligations or in U.S.

36

issuers. Similarly, the Trustees concluded that, generally, small capitalization equity funds and focused funds including state specific municipal funds, require greater intensity of research and trading acumen than larger capitalization or more diversified funds. See "The Fund" in each Fund's Prospectus.

Based on the foregoing, the Trustees concluded that the fees to be paid the Advisor under the advisory agreement were fair and reasonable, given the scope and quality of the services rendered by the Advisor.

General

Messrs. Lowry, Mayer and Neuhauser are also trustees/directors of the Liberty All-Star Funds.

The Trustees serve as trustees of86 registered investment companies managed by the Advisor for which each Trustee receives a retainer at the annual rate of $45,000 and an attendance fee of $9,500 for each regular and special joint board meeting and $1,000 for each special telephonic joint board meeting. Beginning in December, 2003, Mr. Theobald began serving as the Chairman of the Board. As the independent chairman of the board, Mr. Theobald receives a supplemental retainer at the annual rate of of $100,000; the chair of the Audit Committee receives a supplemental retainer at the annual rate of $10,000; the chair of each other committee receives a supplemental retainer at the annual rate of $5,000. Members of each committee, except the Audit Committee, receive $1,500 for each committee meeting. Each Audit Committee member receives $2,000 for each Audit Committee meeting. Committee members receive $1,500 for each special committee meeting attended on a day other than a regular joint board meeting day. Two-thirds of the Trustee fees are allocated among the Funds based on each Fund's relative net assets and one-third of the fees is divided equally among the Funds.

Trustees and officers of the Trust, who are also officers of the Advisor or its affiliates, will benefit from the advisory fees, sales commissions and agency fees paid or allowed by the Trust.

The Agreement and Declaration of Trust (Declaration) of the Trust provides that the Trust will indemnify its Trustees and officers against liabilities and expenses incurred in connection with litigation in which they may be involved because of their offices with the Trust but that such indemnification will not relieve any officer or Trustee of any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties. The Trust, at its expense, provides liability insurance for the benefit of its Trustees and officers.

The Trustees have the authority to convert the Funds into a master fund/feeder fund structure. Under this structure, a Fund may invest all or a portion of its investable assets in investment companies with substantially the same investment goals, policies and restrictions as the Fund. The primary reason to use the master fund/feeder fund structure is to provide a mechanism to pool, in a single master fund, investments of different investor classes, resulting in a larger portfolio, investment and administrative efficiencies and economies of scale.

MANAGEMENT AGREEMENT

Under a Management Agreement (Agreement), the Advisor has contracted to furnish each Fund with investment research and recommendations or fund management, respectively, and accounting and administrative personnel and services, and with office space, equipment and other facilities. For these services and facilities, each Fund pays a monthly fee based on the average of the daily closing value of the total net assets of each Fund for such month. Under the Agreement, any liability of the Advisor to the Trust, a Fund and/or its shareholders is limited to situations involving the Advisor's own willful misfeasance, bad faith, gross negligence or reckless disregard of its duties.

The Agreement may be terminated with respect to the Fund at any time on 60 days' written notice by the Advisor or by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund. The Agreement will automatically terminate upon any assignment thereof and shall continue in effect from year to year only so long as such continuance is approved at least annually
(i) by the Trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund and (ii) by vote of a majority of the Trustees who are not interested persons (as such term is defined in the 1940 Act) of the Advisor or the Trust, cast in person at a meeting called for the purpose of voting on such approval.

The Advisor pays all salaries of officers of the Trust. The Trust pays all expenses not assumed by the Advisor including, but not limited to, auditing, legal, custodial, investor servicing and shareholder reporting expenses. The Trust pays the cost of printing and mailing any Prospectuses sent to shareholders. Columbia Management Distributors, Inc. (formerly named Columbia Funds Distributor, Inc.) pays the cost of printing and distributing all other Prospectuses.

ADMINISTRATION AGREEMENT (THIS SECTION APPLIES ONLY TO CERTAIN FUNDS AND THEIR RESPECTIVE TRUSTS. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION REGARDING YOUR FUND).

37

Under an Administration Agreement, the Advisor, in its capacity as the Administrator to each Fund, has contracted to perform the following administrative services:

(a) providing office space, equipment and clerical personnel;

(b) arranging, if desired by the respective Trust, for its directors, officers and employees to serve as Trustees, officers or agents of each Fund;

(c) preparing and, if applicable, filing all documents required for compliance by each Fund with applicable laws and regulations;

(d) preparation of agendas and supporting documents for and minutes of meetings of Trustees, committees of Trustees and shareholders;

(e) coordinating and overseeing the activities of each Fund's other third-party service providers; and

(f) maintaining certain books and records of each Fund.

With respect to Columbia Money Market Fund and Columbia Municipal Money Market Fund, the Administration Agreement for these Funds provides that the Advisor will monitor compliance by the Fund with Rule 2a-7 under the 1940 Act and report to the Trustees from time to time with respect thereto.

The Advisor is paid a monthly fee at the annual rate of average daily net assets set forth in Part 1 of this SAI.

TRUST SERVICES AGREEMENT

Pursuant to a Trust Services Agreement, CMS provides the Columbia Tax-Managed Growth Fund's Trust Shares with trust administration services, including tax return preparation and filing, other tax and beneficiary reporting and recordkeeping. CMS's fee is described in the Prospectuses of the Columbia Tax-Managed Growth Fund.

The Pricing and Bookkeeping Agreement

The Advisor is responsible for providing accounting and bookkeeping services to each Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (Outsourcing Agreement), the Advisor has delegated those functions to State Street Corporation (State Street). The Advisor pays fees to State Street under the Outsourcing Agreement. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF
THIS SAI FOR INFORMATION ON THESE FEES.

PORTFOLIO TRANSACTIONS

INVESTMENT DECISIONS. The Advisor acts as investment advisor to each of the Funds. Various officers and Trustees of the Trust also serve as officers or Trustees of other funds and the other corporate or fiduciary clients of the Advisor. The Funds and clients advised by the Advisor or the Funds administered by the Advisor sometimes invest in securities in which the Fund also invests and sometimes engage in covered option writing programs and enter into transactions utilizing stock index options and stock index and financial futures and related options ("other instruments"). If the Fund, such other funds and such other clients desire to buy or sell the same portfolio securities, options or other instruments at about the same time, the purchases and sales are normally made as nearly as practicable on a pro rata basis in proportion to the amounts desired to be purchased or sold by each. Although in some cases these practices could have a detrimental effect on the price or volume of the securities, options or other instruments as far as the Fund is concerned, in most cases it is believed that these practices should produce better executions. It is the opinion of the Trustees that the desirability of retaining the Advisor as investment advisor to the Funds outweighs the disadvantages, if any, which might result from these practices.

POTENTIAL CONFLICTS OF INTEREST IN MANAGING MULTIPLE ACCOUNTS

Like other investment professionals with multiple clients, a portfolio manager for a Fund may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The paragraphs below describe some of these potential conflicts, which the Advisor believes are faced by investment professionals at most major financial firms. The Advisor and the Trustees of the Columbia Funds have adopted compliance policies and procedures that attempt to address certain of these potential conflicts.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance ("performance fee accounts"), may raise potential conflicts of interest by creating an incentive to favor higher-fee accounts. These potential conflicts may include, among others:

- The most attractive investments could be allocated to higher-fee accounts or performance fee accounts.

38

- The trading of higher-fee accounts could be favored as to timing and/or execution price. For example, higher-fee accounts could be permitted to sell securities earlier than other accounts when a prompt sale is desirable or to buy securities at an earlier and more opportune time.

- The trading of other accounts could be used to benefit higher-fee accounts (front-running).

- The investment management team could focus their time and efforts primarily on higher-fee accounts due to a personal stake in compensation.

Potential conflicts of interest may also arise when the portfolio managers have personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to limited exceptions, the Advisor's investment professionals do not have the opportunity to invest in client accounts, other than the Columbia Funds.

A potential conflict of interest may arise when a Fund and other accounts purchase or sell the same securities. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Advisor's trading desk may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if one account is favored over another in allocating the securities purchased or sold - for example, by allocating a disproportionate amount of a security that is likely to increase in value to a favored account.

"Cross trades," in which one Columbia account sells a particular security to another account (potentially saving transaction costs for both accounts), may also pose a potential conflict of interest. Cross trades may be seen to involve a potential conflict of interest if, for example, one account is permitted to sell a security to another account at a higher price than an independent third party would pay. The Advisor and the Funds' Trustees have adopted compliance procedures that provide that any transactions between a Fund and another Columbia-advised account are to be made at an independent current market price, as required by law.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts. For example, another account may have a shorter-term investment horizon or different investment objectives, policies or restrictions than a Fund. Depending on another account's objectives or other factors, a portfolio manager may give advice and make decisions that may differ from advice given, or the timing or nature of decisions made, with respect to a Fund. In addition, investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a particular security may be bought or sold for certain accounts even though it could have been bought or sold for other accounts at the same time. More rarely, a particular security may be bought for one or more accounts managed by a portfolio manager when one or more other accounts are selling the security (including short sales). There may be circumstances when purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts.

A Fund's portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. As a result, the portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. The effects of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

A Fund's portfolio managers may be able to select or influence the selection of the brokers and dealers that are used to execute securities transactions for the Fund. In addition to executing trades, some brokers and dealers provide portfolio managers with brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934), which may result in the payment of higher brokerage fees than might have otherwise be available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to the fund, a portfolio manager's decision as to the selection of brokers and dealers could yield disproportionate costs and benefits among the funds and/or accounts that he or she manages.

The Advisor or an affiliate may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of fund and/or accounts that provide greater overall returns to the investment manager and its affiliates.

A Fund's portfolio manager(s) may also face other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could be deemed to exist in managing both a Fund and other accounts. In addition, a Fund's portfolio manager may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel at the Advisor, including each Fund's portfolio manager, are subject to restrictions on engaging in personal securities transactions

39

pursuant to Codes of Ethics adopted by the Advisor and each Fund, which contain provisions and requirements designed to identify and address certain conflicts of interest between personal investment activities and the interests of each Fund.

BROKERAGE AND RESEARCH SERVICES. Consistent with the Conduct Rules of the National Association of Securities Dealers, Inc., and subject to seeking "best execution" (as defined below) and such other policies as the Trustees may determine, the Advisor may consider sales of shares of the Funds as a factor in the selection of broker-dealers to execute securities transactions for a Fund.

The Advisor places the transactions of the Funds with broker-dealers selected by the Advisor and, if applicable, negotiates commissions. Broker-dealers may receive brokerage commissions on portfolio transactions, including the purchase and writing of options, the effecting of closing purchase and sale transactions, and the purchase and sale of underlying securities upon the exercise of options and the purchase or sale of other instruments. The Funds from time to time also execute portfolio transactions with such broker-dealers acting as principals. The Funds do not intend to deal exclusively with any particular broker-dealer or group of broker-dealers.

It is the Advisor's policy generally to seek best execution, which is to place the Funds' transactions where the Funds can be expected to obtain the most favorable combination of price and execution services in particular transactions or provided on a continuing basis by a broker-dealer, and to deal directly with a principal market maker in connection with over-the-counter transactions, except when it is believed that best execution is obtainable elsewhere. In evaluating the execution services of, including the overall reasonableness of brokerage commissions paid to, a broker-dealer, consideration is given to, among other things, the firm's general execution and operational capabilities, and to its reliability, integrity and financial condition.

Securities transactions of the Funds may be executed by broker-dealers who also provide research services (as defined below) to the Advisor and the Funds. The Advisor may use all, some or none of such research services in providing investment advisory services to each of its investment company and other clients, including the Fund. To the extent that such services are used by the Advisor, they tend to reduce the Advisor's expenses. In the Advisor's opinion, it is impossible to assign an exact dollar value for such services.

The Trustees have authorized the Advisor to cause the Funds to pay a broker-dealer which provides brokerage and research services to the Advisor an amount of commission for effecting a securities transaction, including the sale of an option or a closing purchase transaction, for the funds in excess of the amount of commission which another broker-dealer would have charged for effecting that transaction. As provided in Section 28(e) of the Securities Exchange Act of 1934, "brokerage and research services" include advice as to the value of securities, the advisability of investing in, purchasing or selling securities and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issues, industries, securities, economic factors and trends and portfolio strategy and performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement). The Advisor must determine in good faith that such greater commission is reasonable in relation to the value of the brokerage and research services provided by the executing broker-dealer viewed in terms of that particular transaction or the Advisor's overall responsibilities to the Funds and all its other clients.

The Trustees have authorized the Advisor to utilize the services of a clearing agent with respect to all call options written by Funds that write options and to pay such clearing agent commissions of a fixed amount per share (currently 1.25 cents) on the sale of the underlying security upon the exercise of an option written by a Fund.

The Advisor may use the services of affiliated broker-dealers, when buying or selling securities for a Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Advisor must ensure that commissions a Fund pays to affiliates of the Advisor on portfolio transactions are reasonable and fair compared to commissions received by other broker-dealers in connection with comparable transactions involving similar securities being bought or sold at about the same time. The Advisor will report quarterly to the Trustees on all securities transactions placed through affiliates of the Advisor so that the Trustees may consider whether such trades complied with these procedures and the Rule.

PRINCIPAL UNDERWRITER

CMD is the principal underwriter of the Trust's shares. CMD has no obligation to buy the Funds' shares, and purchases the Funds' shares only upon receipt of orders from authorized FSFs or investors.

INVESTOR SERVICING AND TRANSFER AGENT

CMS is the Trust's investor servicing agent (transfer, plan and dividend disbursing agent), for which it receives fees which are paid monthly by the Trust. The fee paid to CMS is based on number of accounts plus reimbursement for certain out-of-pocket expenses. SEE "FUND CHARGES AND EXPENSES" IN PART 1 OF THIS SAI FOR INFORMATION ON FEES RECEIVED BY CMS. The agreement continues indefinitely but may be terminated by 90 days' notice by the Fund to CMS or generally by 6 months' notice by CMS to the Fund. The agreement limits the liability of CMS to the Fund for loss or damage incurred by the Fund to situations involving a failure of CMS to use reasonable care or to act in good faith and without negligence in performing its duties under the agreement. The Fund will indemnify CMS from, among other things, any and all claims, actions, suits, losses, costs, damages, and expenses incurred by it in connection with its acceptance of this Agreement, provided that: (i) to the extent such claims, actions, suits, losses, costs, damages, or expenses relate

40

solely to a particular series or group of series of shares, such indemnification shall be only out of the assets of that series or group of series; (ii) this indemnification shall not apply to actions or omissions constituting negligence or misconduct of CMS or its agents or contractors, including but not limited to willful misfeasance, bad faith or gross negligence in the performance of their duties, or reckless disregard of their obligations and duties under this Agreement; and (iii) CMS shall give a Fund prompt notice and reasonable opportunity to defend against any such claim or action in its own name or in the name of CMS.

CODE OF ETHICS

The Funds, the Advisor, and CMD have adopted Codes of Ethics pursuant to the requirements of the Act. These Codes of Ethics permit personnel subject to the Codes to invest in securities, including securities that may be purchased or held by the Funds. These Codes of Ethics can be reviewed and copied at the SEC's Public Reference Room and may be obtained by calling the SEC at 1-202-942-8090. These Codes are also available on the EDGAR Database on the SEC's internet web site at http://www.sec.gov, and may also be obtained, after paying a duplicating fee, by electronic request to publicinfo@sec.gov or by writing to the SEC's Public Reference Section, Washington, D.C. 20549-0102.

Anti-Money Laundering Compliance

The Funds are required to comply with various anti-money laundering laws and regulations. Consequently, the Funds may request additional information from you to verify your identity. If at any time the Funds believe a shareholder may be involved in suspicious activity or if certain account information matches information on government lists of suspicious persons, the Funds may choose not to establish a new account or may be required to "freeze" a shareholder's account, halting all shareholder activity with respect to such account. The Funds also may be required to provide a governmental agency with information about transactions that have occurred in a shareholder's account or to transfer monies received to establish a new account, transfer an existing account or transfer the proceeds of an existing account to a governmental agency. In some circumstances, the law may not permit a Fund to inform the shareholder that it has taken the actions described above.

Proxy Voting Policies and Fund Proxy Voting Record

THE FUND HAS DELEGATED TO THE ADVISOR THE RESPONSIBILITY TO VOTE PROXIES RELATING TO PORTFOLIO SECURITIES HELD BY THE FUND. IN DECIDING TO DELEGATE THIS RESPONSIBILITY TO THE ADVISOR, THE BOARD OF TRUSTEES OF THE TRUST REVIEWED AND APPROVED THE POLICIES AND PROCEDURES ADOPTED BY THE ADVISOR. THESE INCLUDED THE PROCEDURES THAT THE ADVISOR FOLLOWS WHEN A VOTE PRESENTS A CONFLICT BETWEEN THE INTERESTS OF THE FUND AND ITS SHAREHOLDERS AND THE ADVISOR, ITS AFFILIATES, ITS OTHER CLIENTS OR OTHER PERSONS.

THE ADVISOR'S POLICY IS TO VOTE ALL PROXIES FOR FUND SECURITIES IN A MANNER CONSIDERED BY THE ADVISOR TO BE IN THE BEST INTEREST OF THE FUND AND ITS SHAREHOLDERS WITHOUT REGARD TO ANY BENEFIT TO THE ADVISOR, ITS AFFILIATES, ITS OTHER CLIENTS OR OTHER PERSONS. THE ADVISOR EXAMINES EACH PROPOSAL AND VOTES AGAINST THE PROPOSAL, IF, IN ITS JUDGMENT, APPROVAL OR ADOPTION OF THE PROPOSAL WOULD BE EXPECTED TO IMPACT ADVERSELY THE CURRENT OR POTENTIAL MARKET VALUE OF THE ISSUER'S SECURITIES. THE ADVISOR ALSO EXAMINES EACH PROPOSAL AND VOTES THE PROXIES AGAINST THE PROPOSAL, IF, IN ITS JUDGMENT, THE PROPOSAL WOULD BE EXPECTED TO AFFECT ADVERSELY THE BEST INTEREST OF THE FUND. THE ADVISOR DETERMINES THE BEST INTEREST OF THE FUND IN LIGHT OF THE POTENTIAL ECONOMIC RETURN ON THE FUND'S INVESTMENT.

The Advisor addresses potential material conflicts of interest by having predetermined voting guidelines. For those proposals that require special consideration or in instances where special circumstances may require varying from the predetermined guideline, the Advisor's Proxy Committee determines the vote in the best interest of the Fund, without consideration of any benefit to the Advisor, its affiliates, its other clients or other persons. The Advisor's Proxy Committee is composed of representatives of the Advisor's equity investments, equity research, compliance, legal and fund administration functions. In addition to the responsibilities described above, the Proxy Committee has the responsibility to review, on a semi-annual basis, the Advisor's proxy voting policies to ensure consistency with internal and regulatory agency policies and to develop additional predetermined voting guidelines to assist in the review of proxy proposals.

THE PROXY COMMITTEE MAY VARY FROM A PREDETERMINED GUIDELINE IF IT DETERMINES THAT VOTING ON THE PROPOSAL ACCORDING TO THE PREDETERMINED GUIDELINE WOULD BE EXPECTED TO IMPACT ADVERSELY THE CURRENT OR POTENTIAL MARKET VALUE OF THE ISSUER'S SECURITIES OR TO AFFECT ADVERSELY THE BEST INTEREST OF THE CLIENT. REFERENCES TO THE BEST INTEREST OF A CLIENT REFER TO THE INTEREST OF THE CLIENT IN TERMS OF THE POTENTIAL ECONOMIC RETURN ON THE CLIENT'S INVESTMENT. IN DETERMINING THE VOTE ON ANY PROPOSAL, THE PROXY COMMITTEE DOES NOT CONSIDER ANY BENEFIT OTHER THAN BENEFITS TO THE OWNER OF THE SECURITIES TO BE VOTED. A MEMBER OF THE PROXY COMMITTEE IS PROHIBITED FROM VOTING ON ANY PROPOSAL FOR WHICH HE OR SHE HAS A CONFLICT OF INTEREST BY REASON OF A DIRECT RELATIONSHIP WITH THE ISSUER OR OTHER PARTY AFFECTED BY A GIVEN PROPOSAL. PERSONS MAKING RECOMMENDATIONS TO THE PROXY COMMITTEE OR ITS MEMBERS ARE REQUIRED TO DISCLOSE TO THE COMMITTEE ANY RELATIONSHIP WITH A PARTY MAKING A PROPOSAL OR OTHER MATTER KNOWN TO THE PERSON THAT WOULD CREATE A POTENTIAL CONFLICT OF INTEREST.

The Advisor has retained Institutional Shareholder Services ("ISS"), a third party vendor, to implement its proxy voting process. ISS provides proxy analysis, record keeping services and vote disclosure services.

41

The Advisor's proxy voting guidelines and procedures are included in this SAI as Appendix II. In accordance with SEC regulations, the fund's proxy voting record for the last twelve-month period ended June 30 has been filed with the SEC. You may obtain a copy of the fund's proxy voting record (i) at www.columbiamanagement.com; (ii) on the Securities and Exchange Commission's website at www.sec.gov and (iii) without charge, upon request, by calling 800-368-0346.

Disclosure of Portfolio Information

The Trustees of the Columbia Funds have adopted policies with respect to the disclosure of the Funds' portfolio holdings by the Funds, Columbia Advisors, or their affiliates. These policies provide that Fund portfolio holdings information generally may not be disclosed to any party prior to (1) the day next following the posting of such information on the Funds' website at www.columbiafunds.com, (2) the day next following the filing of the information with the SEC in a required filing, or (3) for money market funds, such information is publicly available to all shareholders upon request on the fifth business day after each calendar month-end. Certain limited exceptions pursuant to the Fund's policies are described below. The Trustees shall be updated as needed regarding the Fund's compliance with the policies, including information relating to any potential conflicts of interest between the interests of Fund shareholders and those of Columbia Advisors and its affiliates. The Fund's policies prohibit Columbia Advisors and the Fund's other service providers from entering into any agreement to disclose Fund portfolio holdings information in exchange for any form of consideration. These policies apply to disclosures to all categories of persons, including, without limitation, individual investors, institutional investors, intermediaries that distribute the Fund's shares, third-party service providers, rating and ranking organizations and affiliated persons of the Fund.

PUBLIC DISCLOSURES. The Fund's portfolio holdings are currently disclosed to the public through required filings with the SEC and, for equity and fixed income funds, on the Fund's website at www.columbiafunds.com. The Fund files its portfolio holdings with the SEC for each fiscal quarter on Form N-CSR (with respect to each annual period and semi-annual period) and Form N-Q (with respect to the first and third quarters of the Fund's fiscal year). Shareholders may obtain the Fund's Forms N-CSR and N-Q filings on the SEC's website at www.sec.gov. In addition, the Fund's Forms N-CSR and N-Q filings may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's website or the operation of the public reference room.

The equity and fixed income Columbia Funds also currently make portfolio information publicly available at www.columbiafunds.com, as disclosed in the following table:

                                                            FREQUENCY OF
   TYPE OF FUND              INFORMATION PROVIDED            DISCLOSURE            DATE OF WEB POSTING
   ------------              --------------------            ----------            -------------------
Equity Funds         Full portfolio holdings information.      Monthly      30 calendar days after month-end.
Fixed Income Funds   Full portfolio holdings information.     Quarterly    60 calendar days after quarter-end

The scope of the information provided relating to the Fund's portfolio that is made available on the website may change from time to time without prior notice.

For Columbia's money market funds, a complete list of a Fund's portfolio holdings shall be publicly available on a monthly basis on the fifth business day after month-end. Shareholders may request such information by writing or calling the Fund's distributor, Columbia Management Distributors, Inc. at the address listed on the cover of this SAI.

A Fund, Columbia Advisors or their affiliates may include portfolio holdings information that has already been made public through a web posting or SEC filing in marketing literature and other communications to shareholders, advisors or other parties, provided that the information is disclosed no earlier than the day after the date the information is disclosed publicly.

OTHER DISCLOSURES. The Fund's policies provide that non-public disclosures of the Fund's portfolio holdings may be made if (1) the Fund has a legitimate business purpose for making such disclosure, (2) the Fund's chief executive officer authorizes such non-public disclosure of information, and (3) the party receiving the non-public information enters into a confidentiality agreement, which includes a duty not to trade on the non-public information.

The Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information in order to assist the Fund with its day-to-day business affairs. In addition to Columbia Advisors and its affiliates, these service providers include the Fund's custodian and sub-custodians, the Fund's independent registered public accounting firm, legal counsel, financial printers(R.R. Donnelly & Sons and Bowne & Co., Inc.), the Fund's proxy voting service provider (Alamo Direct Mail Services, Inc.), the Fund's proxy solicitor (Georgeson Shareholder Communications Inc.), rating agencies that maintain ratings on certain Columbia Funds

42

(Fitch, Inc.) and service providers that support Columbia Advisors' trading systems (InvestorTool, Inc. and Thomson Financial). These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. The Fund may also disclose portfolio holdings information to broker/dealers and certain other entities related to potential transactions and management of the Fund, provided that reasonable precautions, including limitations on the scope of the portfolio holdings information disclosed, are taken to avoid any potential misuse of the disclosed information.

Certain clients of the Fund's investment adviser(s) may follow a strategy similar to that of the Fund, and have access to portfolio holdings information for their account. It is possible that such information could be used to infer portfolio holdings information relating to the Fund.

DETERMINATION OF NET ASSET VALUE

Each Fund determines net asset value (NAV) per share for each class as of the close of the New York Stock Exchange (Exchange) (generally 4:00 p.m. Eastern time) each day the Exchange is open, except that certain classes of assets, such as index futures, for which the market close occurs shortly after the close of regular trading on the Exchange will be priced at the closing time of the market on which they trade. Currently, the Exchange is closed Saturdays, Sundays and the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Funds with portfolio securities which are primarily listed on foreign exchanges may experience trading and changes in NAV on days on which such Fund does not determine NAV due to differences in closing policies among exchanges. This may significantly affect the NAV of the Fund's redeemable securities on days when an investor cannot redeem such securities Debt securities generally are valued by a pricing service which determines valuations based upon market transactions for normal, institutional-size trading units of similar securities. However, in circumstances where such prices are not available or where the Advisor deems it appropriate to do so, an over-the-counter or exchange bid quotation is used. Securities listed on an exchange or on NASDAQ are valued at the last sale price (or the official closing price as determined by the NASDAQ system, if different, as applicable). Listed securities for which there were no sales during the day and unlisted securities generally are valued at the last quoted bid price. Options are valued at the last sale price or in the absence of a sale, the mean between the last quoted bid and offering prices. Short-term obligations with a maturity of 60 days or less are valued at amortized cost pursuant to procedures adopted by the Trustees. The values of foreign securities quoted in foreign currencies are translated into U.S. dollars at the exchange rate for that day. Portfolio positions for which market quotations are not readily available and other assets are valued at fair value as determined by the Advisor in good faith under the direction of the Trust's Board of Trustees.

Generally, trading in certain securities (such as foreign securities) is substantially completed each day at various times prior to the close of the Exchange. Trading on certain foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets takes place on days which are not business days in New York and on which the Fund's NAV is not calculated. The values of these securities used in determining the NAV are computed as of such times. Also, because of the amount of time required to collect and process trading information as to large numbers of securities issues, the values of certain securities (such as convertible bonds, U.S. government securities, and tax-exempt securities) are determined based on market quotations collected earlier in the day at the latest practicable time prior to the close of the Exchange. Occasionally, events affecting the value of such securities may occur between such times and the close of the Exchange which will not be reflected in the computation of each Fund's NAV. If events materially affecting the value of such securities occur during such period, then these securities will be valued at fair value following procedures approved by the Trust's Board of Trustees.

(The following two paragraphs are applicable only to Columbia Newport Tiger Fund and Columbia Newport Greater China Fund).

Trading in securities on stock exchanges and over-the-counter markets in foreign securities markets is normally completed well before the close of the business day in New York. Trading on foreign securities markets may not take place on all business days in New York, and trading on some foreign securities markets does take place on days which are not business days in New York and on which the Fund's NAV is not calculated.

The calculation of the Fund's NAV accordingly may not take place contemporaneously with the determination of the prices of the Fund's portfolio securities used in such calculations. Events affecting the values of portfolio securities that occur between the time their prices are determined and the close of the Exchange (when the Fund's NAV is calculated) will not be reflected in the Fund's calculation of NAV unless the Advisor, acting under procedures established by the Board of Trustees of the Trust, deems that the particular event would materially affect the Fund's NAV, in which case an adjustment will be made. Assets or liabilities initially expressed in terms of foreign currencies are translated prior to the next determination of the NAV of the Fund's shares into U.S. dollars at prevailing market rates.

AMORTIZED COST FOR MONEY MARKET FUNDS (SEE "AMORTIZED COST FOR MONEY MARKET FUNDS" UNDER "INFORMATION CONCERNING THE FUND" IN PART 1 OF THE SAI OF COLUMBIA MONEY MARKET FUND (FORMERLY NAMED LIBERTY MONEY MARKET FUND) AND COLUMBIA MUNICIPAL MONEY MARKET FUND (FORMERLY NAMED LIBERTY MUNICIPAL MONEY MARKET FUND) ) Money market funds generally value their portfolio securities at amortized cost according to Rule 2a-7 under the 1940 Act.

43

Under the amortized cost method a security is initially valued at cost and thereafter any discount or premium from maturity value is amortized ratably to maturity. This method assures a constant NAV but may result in a yield different from that of the same portfolio under the market value method. The Trust's Trustees have adopted procedures intended to stabilize a money market fund's NAV per share at $1.00. If a money market fund's market value deviates from the amortized cost of $1.00, and results in a material dilution to existing shareholders, the Trust's Trustees will take corrective action that may include:
realizing gains or losses; shortening the portfolio's maturity; withholding distributions; redeeming shares in kind; or converting to the market value method (in which case the NAV per share may differ from $1.00). All investments will be determined pursuant to procedures approved by the Trust's Trustees to present minimal credit risk.

See the Statement of Assets and Liabilities in the shareholder report of the Columbia Money Market Fund (formerly named Liberty Money Market Fund) or the Columbia Municipal Money Market Fund (formerly named Liberty Municipal Money Market Fund) for a specimen price sheet showing the computation of maximum offering price per share of Class A shares.

HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of the Fund and tables of charges. This SAI contains additional information which may be of interest to investors.

The Fund may accept unconditional orders for shares to be executed at the public offering price based on the NAV per share next determined after the order is placed in good order. The public offering price is the NAV plus the applicable sales charge, if any. In the case of orders for purchase of shares placed through FSFs, the public offering price will be determined on the day the order is placed in good order, but only if the FSF receives the order prior to the time at which shares are valued and transmits it to the Fund before the Fund processes that day's transactions. If the FSF fails to transmit before the Fund processes that day's transactions, the customer's entitlement to that day's closing price must be settled between the customer and the FSF. If the FSF receives the order after the time at which the Fund values its shares, the price will be based on the NAV determined as of the close of the Exchange on the next day it is open. If funds for the purchase of shares are sent directly to CMS, they will be invested at the public offering price next determined after receipt in good order. Payment for shares of the fund must be in U.S. dollars; if made by check, the check must be drawn on a U.S. bank.

Investors should understand that, since the offering price of the Fund's shares is calculated to two decimal places using standard rounding methodology, the dollar amount of the sales charge paid as a percentage of the offering price and of the net amount invested for any particular purchase of fund shares may be higher or lower depending on whether downward or upward rounding was required during the calculation process.

The Fund receives the entire NAV of shares sold. For shares subject to an initial sales charge, CMD's commission is the sales charge shown in the Fund's Prospectus less any applicable FSF discount. The FSF discount is the same for all FSFs, except that CMD retains the entire sales charge on any sales made to a shareholder who does not specify a FSF on the Investment Account Application ("Application"), and except that CMD may from time to time reallow additional amounts to all or certain FSFs. CMD generally retains some or all of any asset-based sales charge (distribution fee) or contingent deferred sales charge. Such charges generally reimburse CMD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by the purchaser's bank or checkwriting privilege checks for which there are insufficient funds in a shareholder's account to cover redemption may subject such purchaser or shareholder to a $15 service fee for each check returned. Checks must be drawn on a U.S. bank and must be payable in U.S. dollars. Travelers checks, gift checks, credit card convenience checks, credit cards, cash and ban counter (starter checks) are not accepted.

CMS acts as the shareholder's agent whenever it receives instructions to carry out a transaction on the shareholder's account. Upon receipt of instructions that shares are to be purchased for a shareholder's account, the designated FSF will receive the applicable sales commission. Shareholders may change FSFs at any time by written notice to CMS, provided the new FSF has a sales agreement with CMD.

Shares credited to an account are transferable upon written instructions in good order to CMS and may be redeemed as described under "How to Sell Shares" in the Prospectus. Certificates are not available for any class of shares offered by the Fund. If you currently hold previously issued share certificates, you may send the certificates to CMS for deposit to your account.

In addition to the commissions specified in a Fund's prospectus and this SAI, CMD, or its advisory affiliates, from their own resources, may make cash payments to FSFs that agree to promote the sale of shares of funds that CMD distributes. A number of factors may be considered in determining the amount of those payments, including the FSF's sales, client assets invested in the funds and redemption rates, the quality of the FSF's relationship with CMD and/or its affiliates, and the nature of the services provided by FSFs to its clients.

The payments may be made in recognition of such factors as marketing support, access to sales meetings and the FSF's representatives, and inclusion of the Fund on focus, select or other similar lists.

Subject to applicable rules, CMD may also pay non-cash compensation to FSFs and their representatives, including: (i) occasional gifts (ii) occasional meals, or other entertainment; and/or (iii) support for FSF educational or training events.

In addition, CMD, and/or the Fund's investment advisor, transfer agent or their affiliates, may pay service, administrative or other similar fees to broker/dealers, banks, third-party administrators or other financial institutions (each commonly referred to as an "intermediary"). Those fees are generally for subaccounting, sub-transfer agency and other shareholder services associated with shareholders whose shares are held of record in omnibus or other group accounts. The rate of those fees may vary and is generally calculated on the average daily net assets of a Fund attributable to a particular intermediary.

In some circumstances, the payments discussed above may create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of a Fund.

CMD and its affiliates anticipate that the FSFs and intermediaries that will receive the additional compensation described above include:

SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or eliminated at any time.

AUTOMATIC INVESTMENT PLAN. As a convenience to investors, shares of most Funds advised by the Advisor may be purchased through the Automatic Investment Plan. Electronic fund transfers for a fixed amount of at least $50 ($25 for IRA) are used to purchase a Fund's shares at the public offering price next determined after CMD receives the proceeds. If your Automatic Investment Plan purchase is by electronic funds transfer, you may request the Automatic Investment Plan purchase for any day. Further information and application forms are available from FSFs or from CMD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B, C, D, T, G and Z). The Automated Dollar Cost Averaging program allows you to exchange $100 or more on a monthly basis from any fund distributed by CMD in which you have a current balance of at least $5,000 into the same class of shares of up to five other Funds. Complete the Automated Dollar Cost Averaging section of the Application. There is no charge for exchanges made pursuant to the Automated Dollar Cost Averaging program. Sales charges may apply if exchanging from a money market fund. Exchanges will continue so long as your fund balance is sufficient to complete the transfers. Your normal rights and privileges as a shareholder remain in full force and effect. Thus you can buy any Fund, exchange between the same Class of shares of Funds by written instruction or by telephone exchange if you have so elected and withdraw amounts from any Fund, subject to the imposition of any applicable CDSC or sales charges.

Any additional payments or exchanges into your Fund will extend the time of the Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax purposes.

You may terminate your program, change the amount of the exchange (subject to the $100 minimum), or change your selection of funds, by telephone or in writing; if in writing by mailing your instructions to Columbia Management Services, Inc. (formerly named Columbia Funds Services, Inc.) (CMS) P.O. Box 8081, Boston, MA 02266-8081.

You should consult your FSF or financial advisor to determine whether or not the Automated Dollar Cost Averaging program is appropriate for you.

CMD offers several plans by which an investor may obtain reduced initial or contingent deferred sales charges. These plans may be altered or discontinued at any time. See "Programs For Reducing or Eliminating Sales Charges" below for more information.

CLASS T SHAREHOLDER SERVICES PLAN. The Trustees have approved a Shareholder Services Plan (the "Services Plan") pursuant to which the Trusts plan to enter into servicing agreements with institutions (including Bank of America Corporation and its affiliates). Pursuant to these servicing agreements, institutions render certain administrative and support services to customers who are the beneficial owners of Class T shares of each Fund other than the Columbia Newport Tiger Fund. Such services are provided to the institution's customers who are the beneficial owners of Class T shares and are intended to supplement the services provided by the Fund's administrator and transfer agent to the shareholders of record of the Class T shares. The Services Plan provides that each Fund will pay fees for such services at an annual rate of up to 0.50% of the average daily net asset value of Class T shares owned beneficially by the institution's

47

customers. Institutions may receive up to one-half of this fee for providing one or more of the following services to such customers: (i) aggregating and processing purchase and redemption requests and placing net purchase and redemption orders with CMD; (ii) processing dividend payments from a Fund; (iii) providing sub-accounting with respect to Class T shares or the information necessary for sub-accounting; and (iv) providing periodic mailings to customers. Institutions may also receive up to one-half of this fee for providing one or more of these additional services to such customers: (i) providing customers with information as to their positions in Class T shares; (ii) responding to customer inquiries; and (iii) providing a service to invest the assets of customers in Class T shares.

The payments under the servicing agreements entered into as of the date of this SAI are limited to an aggregate fee of not more than 0.30% (on an annualized basis) of the average daily net asset value of the Class T shares of equity funds beneficially owned by customers of institutions and 0.15% (on an annualized basis) of the average daily net asset value of the Class T shares of bond funds beneficially owned by customers of institutions. The Funds understand that institutions may charge fees to their customers who are the beneficial owners of Class T shares in connection with their accounts with such institutions. Any such fees would be in addition to any amounts which may be received by an institution under the Services Plan. Under the terms of each servicing agreement, institutions are required to provide to their customers a schedule of any fees that they may charge in connection with customer investments in Class T shares.

Each servicing agreement with an institution ("Service Organization") relating to the Services Plan requires that, with respect to those Funds which declare dividends on a daily basis, the Service Organization agrees to waive a portion of the servicing fee payable to it under the Services Plan to the extent necessary to ensure that the fees required to be accrued with respect to the Class T shares of such Funds on any day do not exceed the income to be accrued to such Class T shares on that day.

The Class T servicing agreements are governed by the Services Plan approved by the Board of Trustees in connection with the offering of Class T shares of each Fund. Pursuant to the Services Plan, the Board of Trustees reviews, at least quarterly, a written report of the amounts paid under the servicing agreements and the purposes for which the expenditures were made. In addition, the arrangements with Service Organizations must be approved annually by a majority of the Trustees, including a majority of the trustees who are not "interested persons" of the Funds as defined in the 1940 Act and who have no direct or indirect financial interest in such arrangements (the "Disinterested Trustees").

The Board of Trustees has approved the service agreements with Service Organizations based on information provided by the Funds' service contractors that there is a reasonable likelihood that the arrangements will benefit the Funds and their shareholders by affording the Funds greater flexibility in connection with the efficient servicing of the accounts of the beneficial owners of Class T shares of the Funds. Any material amendment to the Funds' arrangements with Service Organizations must be approved by a majority of the Board of Trustees (including a majority of the Disinterested Trustees). So long as the service agreements with Service Organizations are in effect, the selection and nomination of the members of Columbia's Board of Trustees who are not "interested persons" (as defined in the 1940 Act) of the Funds will be committed to the discretion of such Disinterested Trustees.

TAX-SHELTERED RETIREMENT PLANS (Retirement Plans). CMD offers prototype tax-qualified plans, including Pension and Profit-Sharing Plans for individuals, corporations, employees and the self-employed. The minimum initial Retirement Plan investment is $25. Columbia Trust Company (CTC) is the Custodian/Trustee and Plan Sponsor of the Columbia Advisor prototype plans offered through CMD. In general, a $20 annual fee is charged. Detailed information concerning these Retirement Plans and copies of the Retirement Plans are available from CMD.

Participants in Retirement Plans not sponsored by CTC, not including Individual Retirement Accounts (IRAs), may be subject to an annual fee of $20 unless the Retirement Plan maintains an omnibus account with CMS. Participants in CTC sponsored prototype plans (other than IRAs) who liquidate the total value of their account may also be charged a $20 close-out processing fee payable to CMS. The close out fee applies to plans opened after September 1, 1996. The fee is in addition to any applicable CDSC. The fee will not apply if the participant uses the proceeds to open a Columbia Advisor IRA Rollover account in any Fund distributed by CMD, or if the Retirement Plan maintains an omnibus account.

Consultation with a competent financial advisor regarding these Retirement Plans and consideration of the suitability of Fund shares as an investment under the Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling CMS, shareholders or their FSF of record may change an address on a recorded telephone line. Confirmations of address change will be sent to both the old and the new addresses. Telephone redemption privileges by check are suspended for 30 days after an address change is effected. Please have your account and taxpayer identification numbers available when calling.

48

CASH CONNECTION. Dividends and any other distributions, including Systematic Withdrawal Plan (SWP) payments, may be automatically deposited to a shareholder's bank account via electronic funds transfer. Shareholders wishing to avail themselves of this electronic transfer procedure should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification reinvestment program (ADD) generally allows shareholders to have all distributions from a Fund automatically invested in the same class of shares of another Fund. An ADD account must be in the same name as the shareholder's existing open account with the particular Fund. Call CMS for more information at 1-800-345-6611.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES

RIGHTS OF ACCUMULATION (Columbia Class A and Class T shares, Nations Class A shares and Galaxy Retail A shares only) (Class T shares can only be purchased by the shareholders of Columbia Newport Tiger Fund (formerly named Liberty Newport Tiger Fund) who already own Class T shares). Reduced sales charges on Class A and T shares can be effected by combining a current purchase of Class A or Class T shares with prior purchases of other funds and classes distributed by CMD. The applicable sales charge is based on the combined total of:

1. the current purchase; and

2. the value at the public offering price at the close of business on the previous day of all shares of funds for which CMD serves as distributor (Funds) held by the shareholder.

CMD must be promptly notified of each purchase with respect to which a shareholder is entitled to a reduced sales charge. Such reduced sales charge will be applied upon confirmation of the shareholder's holdings by CMS. A Fund may terminate or amend this Right of Accumulation.

STATEMENT OF INTENT (Class A, Class E and Class T shares only). Any person may qualify for reduced sales charges on purchases of Class A, E and T shares made within a thirteen-month period pursuant to a Statement of Intent ("Statement"). A shareholder may include, as an accumulation credit toward the completion of such Statement, the value of all fund shares held by the shareholder on the date of the Statement in Funds (except shares of any money market fund, unless such shares were acquired by exchange from Class A shares of another non-money market fund)). The value is determined at the public offering price on the date of the Statement. Purchases made through reinvestment of distributions do not count toward satisfaction of the Statement.

During the term of a Statement, CMS will hold shares in escrow to secure payment of the higher sales charge applicable to Class A, E or T shares actually purchased. Dividends and capital gains will be paid on all escrowed shares and these shares will be released when the amount indicated has been purchased. A Statement does not obligate the investor to buy or a Fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which would qualify for a further quantity discount, a retroactive price adjustment will be made at the time of expiration of the Statement (provided the FSF returns to CMD the excess commission previously paid during the thirteen-month period). The resulting difference in offering price will purchase additional shares for the shareholder's account at the applicable offering price.

If the amount of the Statement is not purchased, the shareholder shall remit to CMD an amount equal to the difference between the sales charge paid and the sales charge that should have been paid. If the shareholder fails within twenty days after a written request to pay such difference in sales charge, CMS will redeem escrowed Class A, E or T shares with a value equal to such difference. The additional FSF commission will be remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available from your FSF, or from CMS at 1-800-345-6611.

NET ASSET VALUE ELIGIBILITY GUIDELINES (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS).

49

Registered broker/dealer firms that have entered into a Nations Funds dealer agreement with BACAP Distributors, LLC may buy Class A shares without paying a front-end sales charge for their investment account only.

Banks, trust companies and thrift institutions, acting as fiduciaries.

2. Grandfathered investors. Any shareholder who owned shares of any fund of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on September 29, 2000 (when all of the then outstanding shares of Columbia Acorn Trust were re-designated Class Z shares) and who since that time has remained a shareholder of any Fund, may purchase Class A shares of any Fund at NAV in those cases where a Columbia Fund Class Z share is not available.

Shareholders of certain Funds that reorganized into the Nations Funds who were entitled to buy shares at (NAV) will continue to be eligible for NAV purchases into those Nations Fund accounts opened through August 19, 2005.

Galaxy Fund shareholders prior to December 1, 1995; and shareholders who
(i) purchased Galaxy Fund Prime A shares at net asset value and received Class A shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Prime A shares were originally purchased.

(For Class T shares only) Shareholders who (i) purchased Galaxy Fund Retail A shares at net asset value and received Class T shares in exchange for those shares during the Galaxy/Liberty Fund reorganization; and (ii) continue to maintain the account in which the Retail A shares were originally purchased; and Boston 1784 Fund shareholders on the date that those funds were reorganized into Galaxy Funds.

3. Reinstatement. Subject to the fund policy on trading of fund shares, an investor who has redeemed class A, B, C, D, G or T shares may, upon request, reinstate within 1 year a portion or all of the proceeds of such sales in shares of class A of any fund at the NAV next determined after Columbia Management Services, Inc. received a written reinstatement request and payment.

4. Retirement Plans. Class A, Class E and Class T shares (Class T shares are not currently open to new investors) of certain funds may also be purchased at reduced or no sales charge by clients of dealers, brokers or registered investment advisors that have entered into arrangements with CMD pursuant to which the funds are included as investments options in wrap fee accounts, other managed agency/asset allocation accounts or programs involving fee-based compensation arrangements, and by participants in certain retirement plans.

50

5. Non-U.S. Investors. Certain pension, profit-sharing or other employee benefit plans offered to non-US investors may be eligible to purchase Class A shares with no sales charge.

6. Reorganizations. At the Fund's discretion, NAV eligibility may apply to shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which the fund is a party.

7. Rights of Accumulation (ROA). The value of eligible accounts, regardless of class, maintained by you and you and your immediate family may be combined with the value of your current purchase to reach a sales discount level and to obtain the lower sales charge for your current purchase.

8. Letters of Intent (LOI). You may pay a lower sales charge when purchasing class A shares by signing a letter of intent. By doing so, you would be able to pay the lower sales charge on all purchases made under the LOI within 13 months. If your LOI purchases are not completed within 13 months, you will be charged the applicable sales charge on the amount you had invested to that date.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES (CDSCS) (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC IN ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR TO CERTAIN FUNDS) (Class A, B, C, D, E, matured F, G and T shares) CDSCs may be waived on redemptions in the following situations with the proper documentation:

1. Death. CDSCs may be waived on redemptions following the death of (i) the sole shareholder on an individual account, (ii) a joint tenant where the surviving joint tenant is the deceased's spouse, or (iii) the beneficiary of a Uniform Gifts to Minors Act (UGMA), Uniform Transfers to Minors Act (UTMA) or other custodial account. If, upon the occurrence of one of the foregoing, the account is transferred to an account registered in the name of the deceased's estate, the CDSC will be waived on any redemption from the estate account If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

2. Systematic Withdrawal Plan (SWP). CDSCs may be waived on redemptions occurring pursuant to a monthly, quarterly or semi-annual SWP established with CMS, to the extent the redemptions do not exceed, on an annual basis, 12% of the account's value at the time that the SWP is established. Otherwise, CDSCs will be charged on SWP redemptions until this requirement is met. For redemptions in excess of 12% of the account's value at the time that the SWP is established, a CDSC will be charged on the SWP redemption. The 12% limit does not apply if the SWP is set up at the time the account is established, and distributions are being reinvested. See below under "How to Sell Shares - Systematic Withdrawal Plan."

3. Disability. CDSCs may be waived on redemptions occurring after the sole shareholder on an individual account or a joint tenant on a spousal joint tenant account becomes disabled (as defined in Section 72(m)(7) of the Internal Revenue Code). To be eligible for such waiver, (i) the disability must arise AFTER the purchase of shares (ii) the disabled shareholder must have been under age 65 at the time of the initial determination of disability, and (iii) a letter from a physician must be signed under penalty of perjury stating the nature of the disability. If the account is transferred to a new registration and then a redemption is requested, the applicable CDSC will be charged.

4. Death of a trustee. CDSCs may be waived on redemptions occurring upon dissolution of a revocable living or grantor trust following the death of the sole trustee where (i) the grantor of the trust is the sole trustee and the sole life beneficiary, (ii) death occurs following the purchase AND
(iii) the trust document provides for dissolution of the trust upon the trustee's death. If the account is transferred to a new registration (including that of a successor trustee), the applicable CDSC will be charged upon any subsequent redemption.

5. Returns of excess contributions. CDSCs may be waived on redemptions required to return excess contributions made to retirement plans or individual retirement accounts, so long as the FSF agrees to return the applicable portion of any commission paid by CMD.

6. Qualified Retirement Plans. CDSCs may be waived on CMD shares sold by employee benefit plans created according to Section 403(b) of the tax code and sponsored by a non-profit organization qualified under Section 501(c)(3) of the tax code. To qualify for the waiver, the plan must be a participant in an alliance program that has signed an agreement with Columbia Funds or CMD.

51

7. Trust Share Taxes. CDSCs will be waived on redemptions of Class E and F shares (i) where the proceeds are used to directly pay trust taxes, and
(ii) where the proceeds are used to pay beneficiaries for the payment of trust taxes.

8. Return of Commission. CDSCs may be waived on shares sold by intermediaries that are part of the Columbia Funds selling group where the intermediary has entered into an agreement with Columbia Funds not to receive (or to return if received) all or any applicable portion of an upfront commission.

9. Non-U.S. Investors. CDSCs may be waived on shares sold by or distributions from certain pension, profit-sharing or other employee benefit plans offered to non-U.S. investors.

10. IRS Section 401 and 457. CDSCs may be waived on shares sold by certain pension, profit-sharing or other employee benefit plans established under
Section 401 or 457 of the tax code.

11. Medical Payments. CDSCs may be waived on shares redeemed for medical payments that exceed 7.5% of income, and distributions made to pay for insurance by an individual who has separated from employment and who has received unemployment compensation under a federal or state program for at least twelve weeks.

12. Plans of Reorganization. At the Funds' discretion, CDSCs may be waived for shares issued in plans of reorganization, such as mergers, asset acquisitions and exchange offers, to which a fund is a party.

13. Charitable Giving Program. CDSCs may be waived on the sale of Class C or Class D shares sold by a non-profit organization qualified under Section 501(c)(3) of the tax code in connection with the Banc of America Capital Management Charitable Giving Program.

14. The CDSC also may be waived where the FSF agrees to return all or an agreed upon portion of the commission earned on the sale of the shares being redeemed.

HOW TO SELL SHARES

Shares may be sold on any day the Exchange is open, either directly to the Fund or through the shareholder's FSF. Sale proceeds generally are sent within seven days (usually on the next business day after your request is received in good form). However, for shares recently purchased by check, the Fund may delay selling or delay sending proceeds from your shares for up to 15 days in order to protect the Fund against financial losses and dilution in net asset value caused by dishonored purchase payment checks.

To sell shares directly to the Fund, send a signed letter of instruction to CMS, along with any certificates for shares to be sold. The sale price is the net asset value (less any applicable contingent deferred sales charge) next calculated after the Fund receives the request in proper form. Signatures must be guaranteed by a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. Stock power forms are available from FSFs, CMS and many banks. Additional documentation may be required for sales by corporations, agents, fiduciaries, surviving joint owners, individual retirement account holders and other legal entities. Call CMS for more information 1-800-345-6611.

FSFs must receive requests before the time at which the Fund's shares are valued to receive that day's price, FSF's are responsible for furnishing all necessary documentation to CMS and may charge for this service.

SYSTEMATIC WITHDRAWAL PLAN (SWP). The shareholder may establish a SWP. A specified dollar amount, share amount or percentage of the then current net asset value of the shareholder's investment in any Fund designated by the shareholder will be paid monthly, quarterly or semi-annually to a designated payee. The amount or percentage the shareholder specifies is run against available shares and generally may not, on an annualized basis, exceed 12% of the value, as of the time the shareholder makes the election, of the shareholder's investment. Withdrawals of shares of the Fund under a SWP will be treated as redemptions of shares purchased through the reinvestment of Fund distributions, or, to the extent such shares in the shareholder's account are insufficient to cover Plan payments, as redemptions from the earliest purchased shares of such Fund in the shareholder's account. No CDSCs apply to a redemption pursuant to a SWP of 12% or less, even if, after giving effect to the redemption, the shareholder's account balance is less than the shareholder's base amount. Qualified plan participants who are required by Internal Revenue Service regulation to withdraw more than 12%, on an annual basis, of the value of their share account may do so but may be subject to a CDSC ranging from 1% to 5% of the amount withdrawn in excess of 12% annually. If a shareholder wishes to participate in a SWP, the shareholder must elect to have all of the shareholder's income dividends and other Fund distributions payable in shares of the Fund rather than in cash.

52

A shareholder or a shareholder's FSF of record may establish a SWP account by telephone on a recorded line. However, SWP checks will be payable only to the shareholder and sent to the address of record. SWPs from retirement accounts cannot be established by telephone.

A shareholder may not establish a SWP if the shareholder holds shares in certificate form. Purchasing additional shares (other than through dividend and distribution reinvestment) while receiving SWP payments is ordinarily disadvantageous because of sales charges. For this reason, a shareholder may not maintain a plan for the accumulation of shares of the Fund (other than through the reinvestment of dividends) and a SWP at the same time.

SWP payments are made through share redemptions, which may result in a gain or loss for tax purposes, may involve the use of principal and may eventually use up all of the shares in a shareholder's account.

A Fund may terminate a shareholder's SWP if the shareholder's account balance falls below $5,000 due to any transfer or liquidation of shares other than pursuant to the SWP. SWP payments will be terminated on receiving satisfactory evidence of the death or incapacity of a shareholder. Until this evidence is received, CMS will not be liable for any payment made in accordance with the provisions of a SWP.

The cost of administering SWPs for the benefit of shareholders who participate in them is borne by the Fund as an expense of all shareholders.

Shareholders whose positions are held in "street name" by certain FSFs may not be able to participate in a SWP. If a shareholder's Fund shares are held in "street name," the shareholder should consult his or her FSF to determine whether he or she may participate in a SWP. The SWP on accounts held in "street name" must be made payable to the back office via the NSCC.

TELEPHONE REDEMPTIONS. All Fund shareholders and/or their FSFs are automatically eligible to redeem up to $100,000 of the Fund's shares by calling 1-800-422-3737 toll-free any business day between 9:00 a.m. and the close of trading of the Exchange (normally 4:00 p.m. Eastern time). Transactions received after 4:00
p.m. Eastern time will receive the next business day's closing price. Telephone redemptions by check and ACH are limited to a total of $100,000 in a 30-day period. Redemptions that exceed $100,000 may be accomplished by placing a wire order trade through a broker, to a pre-existing bank account or furnishing a signature guaranteed request. Signatures must be guaranteed by either a bank, a member firm of a national stock exchange or another eligible guarantor that participates in the Medallion Signature Guarantee Program. CMS will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. Telephone redemptions are not available on accounts with an address change in the preceding 30 days and proceeds and confirmations will only be mailed or sent to the address of record unless the redemption proceeds are being sent to a pre-designated bank account. Shareholders and/or their FSFs will be required to provide their name, address account and taxpayer identification numbers. FSFs will also be required to provide their broker number. All telephone transactions are recorded. A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. Certain restrictions apply to retirement plan accounts.

CHECKWRITING (IN THIS SECTION, THE "ADVISOR" REFERS TO COLUMBIA MANAGEMENT ADVISORS, LLC ITS CAPACITY AS THE ADVISOR OR ADMINISTRATOR OF CERTAIN FUNDS)
(Available only on the Class A and Z shares of certain Funds)

Shares may be redeemed by check if a shareholder has previously completed an Application and Signature Card. CMS will provide checks to be drawn on Mellon Trust of New England, N.A. (the "Bank"). These checks may be made payable to the order of any person in the amount of not less than $500 ($250 for money market funds) nor more than $100,000. The shareholder will continue to earn dividends on shares until a check is presented to the Bank for payment. At such time a sufficient number of full and fractional shares will be redeemed at the next determined net asset value to cover the amount of the check. Certificate shares may not be redeemed in this manner.

Shareholders utilizing checkwriting drafts will be subject to the Bank's rules governing checking accounts. There is currently no charge to the shareholder for the use of checks., However, you may incur customary fees for services such as a stop payment request or a request for copies of a check. The shareholder should make sure that there are sufficient shares in his or her open account to cover the amount of any check drawn since the net asset value of shares will fluctuate. If insufficient shares are in the shareholder's open account, the check will be returned marked "insufficient funds" and no shares will be redeemed; the shareholder will be charged a $15 service fee for each check returned. It is not possible to determine in advance the total value of an open account because prior redemptions and possible changes in net asset value may cause the value of an open account to change. Accordingly, a check redemption should not be used to close an open account. In addition, a check redemption, like any other redemption, may give rise to taxable capital gains.

NON-CASH REDEMPTIONS. For redemptions of any single shareholder within any 90-day period exceeding the lesser of $250,000 or 1% of a Fund's net asset value, a Fund may make the payment or a portion of the payment with portfolio securities held by that Fund instead of cash, in which case the redeeming shareholder may incur brokerage and other costs in selling the securities received.

INFORMATION APPLICABLE TO CLASS G AND CLASS T SHARES

The primary difference between Class G and Class T shares lies in their sales charge structures and shareholder servicing/distribution expenses. Investments in Class T shares of the Funds are subject to a front-end sales charge. Investments in Class G shares of the Funds are subject to a back-end sales charge. This back-end sales charge declines over time and is known as a "contingent deferred sales charge." An investor should understand that the purpose and function of the sales charge structures and shareholder servicing/distribution arrangements for both Class G and Class T shares are the same. Class T shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing fees at an annual rate of up to 0.15% and 0.30%, respectively, of the Fund's average daily net assets attributable to its Class T shares. Class G shares of a bond fund and an equity fund are currently subject to ongoing shareholder servicing and distribution fees at an annual rate of up to 0.80% and 0.95%, respectively, of the Fund's average daily net assets attributable to its Class G shares. These ongoing fees, which are higher than those charged on Class T shares, will cause Class G shares to have a higher expense ratio and pay lower dividends than Class T shares. Class G and Class T shares may only be purchased by current shareholders of Class G and Class T, respectively.

CLASS T SHARES. The public offering price for Class T shares of the Funds is the sum of the net asset value of the Class T shares purchased plus any applicable front-end sales charge as described in the applicable Prospectus. A deferred sales charge of up to 1.00% is assessed on certain redemptions of Class T shares that are purchased with no initial sales charge as part of an investment of $1,000,000 to $25,000,000. A portion of the front-end sales charge may be reallowed to broker-dealers as follows:

The appropriate reallowance to dealers will be paid by CMD to broker-dealer organizations which have entered into agreements with CMD. The reallowance to dealers may be changed from time to time.

Certain affiliates of the Advisor may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers whose customers purchase significant amounts of Class T shares of the Funds. Such compensation will not represent an additional expense to the Funds or their shareholders, since it will be paid from the assets of Bank of America Corporation's affiliates.

INFORMATION APPLICABLE TO CERTAIN CLASS G SHARES RECEIVED BY FORMER GALAXY FUND RETAIL B SHAREHOLDERS IN CONNECTION WITH THE GALAXY/LIBERTY REORGANIZATION. The following table describes the CDSC schedule applicable to Class G shares received by former Galaxy Fund Retail B shareholders in exchange for Retail B Shares purchased prior to January 1, 2001:

                                % DEDUCTED WHEN

Class G shares received in exchange for Galaxy Fund Retail B Shares that were purchased prior to January 1, 2001 will automatically convert to Class T shares seven years after purchase. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

The following table describes the CDSC schedule applicable to Class G shareholders whose Galaxy Asset Allocation Fund and/or International Equity Fund Retail B Shares were acquired in connection with the reorganization of the Pillar Funds:

Through the seventh year              None
Longer than seven years               None

If you acquired Retail B Shares in connection with the reorganization of the Pillar Funds, your Class G shares will automatically convert to Class T shares eight years after you purchased the Pillar Fund Class B shares you held prior to the reorganization. For purposes of calculating the CDSC, all purchases are considered to be made on the first day of the month in which each purchase was made.

CLASS G SHARES PURCHASED AFTER THE GALAXY/LIBERTY REORGANIZATION. The public offering price for Class G shares of the Funds is the net asset value of the Class G shares purchased. Although investors pay no front-end sales charge on purchases of Class G shares, such shares are subject to a contingent deferred sales charge at the rates set forth in the applicable Prospectus if they are redeemed within seven years of purchase. Securities dealers, brokers, financial institutions and other industry professionals will receive commissions from CMD in connection with sales of Class G shares. These commissions may be different than the reallowances or placement fees paid to dealers in connection with sales of Class T shares. Certain affiliates of Columbia may, at their own expense, provide additional compensation to broker-dealer affiliates of Columbia and to unaffiliated broker-dealers, whose customers purchase significant amounts of Class G shares of a Fund. See "Class T Shares." The contingent deferred sales charge on Class G shares is based on the lesser of the net asset value of the shares on the redemption date or the original cost of the shares being redeemed. As a result, no sales charge is imposed on any increase in the principal value of an investor's Class G shares. In addition, a contingent deferred sales charge will not be assessed on Class G shares purchased through reinvestment of dividends or capital gains distributions.

The proceeds from the contingent deferred sales charge that an investor may pay upon redemption go to CMD, which may use such amounts to defray the expenses associated with the distribution-related services involved in selling Class G shares. Class G shares of a Fund will convert automatically to Class T shares eight years after purchase. The purpose of the conversion is to relieve a holder of Class G shares of the higher ongoing expenses charged to those shares, after enough time has passed to allow CMD to recover approximately the amount it would have received if the applicable front-end sales charge had been charged. The conversion from Class G shares to Class T shares takes place at net asset value, as a result of which an investor receives dollar-for-dollar the same value of Class T shares as he or she had of Class G shares. The conversion occurs eight years after the beginning of the calendar month in which the shares are purchased. Upon conversion, the converted shares will be relieved of the distribution and shareholder servicing fees borne by Class G shares, although they will be subject to the shareholder servicing fees borne by Class T shares.

Class G shares acquired through a reinvestment of dividends or distributions are also converted at the earlier of two dates - (i) eight years after the beginning of the calendar month in which the reinvestment occurred or (ii) the date of conversion of the most recently purchased Class G shares that were not acquired through reinvestment of dividends or distributions. For example, if an investor makes a one-time purchase of Class G shares of a Fund, and subsequently acquires additional Class G shares of the Fund only through reinvestment of dividends and/or distributions, all of such investor's Class G shares in the Fund, including those acquired through reinvestment, will convert to Class T shares of the Fund on the same date.

INFORMATION APPLICABLE TO CERTAIN CLASS B SHAREHOLDERS

Except for the following, Class B Share Contingent Deferred Sales Charges ("CDSCs") and conversion schedules are described in the Prospectuses.

The following table describes the CDSC schedule applicable to Class B shares received by Galaxy Quality Plus Bond Fund shareholders in exchange for Prime B Shares in connection with the Galaxy/Liberty reorganization.

Automatic conversion to Class A shares occurs eight years after purchase.

The Class B share discount program for purchases of $250,000 or more is not applicable to Class B shares received by Galaxy Fund Prime B shareholders in connection with the reorganization of the Galaxy Fund.

INFORMATION APPLICABLE TO CERTAIN CLASS A SHAREHOLDERS:

Except as set forth in the following paragraph, Class A share CDSCs are described in the Prospectuses:

Class A shares received by former Galaxy High Quality Bond Fund shareholders in exchange for Prime A Shares in connection with the Galaxy/Liberty reorganization of that Fund are subject to a 1% CDSC upon redemption of such Class A shares if the Prime A Shares were purchased without an initial sales charge in accounts aggregating $1 million or more at the time of purchase and the Class A shares are sold within 12 months of the time of purchase of the Prime A Shares. The 12-month holding period begins on the first day of the month in which each purchase was made.

DISTRIBUTIONS

Distributions are invested in additional shares of the same Class of the Fund at net asset value unless the shareholder elects to receive cash. Regardless of the shareholder's election, distributions of $10 or less will not be paid in cash, but will be invested in additional shares of the same class of the Fund at net asset value. Undelivered distribution checks returned by the post office will be reinvested in your account. If a shareholder has elected to receive dividends and/or capital gain distributions in cash and the postal or other delivery service selected by the Transfer Agent is unable to deliver checks to the shareholder's address of record, such shareholder's distribution option will automatically be converted to having all dividend and other distributions reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution or redemption checks. Shareholders may reinvest all or a portion of a recent cash distribution without a sales charge. No charge is currently made for reinvestment.

Shares of some Funds that pay daily dividends (include Funds) will normally earn dividends starting with the date the Fund receives payment for the shares and will continue through the day before the shares are redeemed, transferred or exchanged. Shares of some Funds that pay daily dividends (exclude Funds) Columbia will be earned starting with the day after that Fund receives payments for the shares. To determine whether a particular Fund is an include or exclude fund, customers can call 1-800-345-6611.

HOW TO EXCHANGE SHARES

Shares of the Fund may be exchanged for the same class of shares of the other continuously offered funds (with certain exceptions) on the basis of the NAVs per share at the time of exchange. Class T and Z shares may be exchanged for Class A shares of certain other funds. The prospectus of each Fund describes its investment goal and policies, and shareholders should obtain a prospectus and consider these goals and policies carefully before requesting an exchange Consult CMS before requesting an exchange.

If you acquire Class A shares of an international fund by exchange from any other fund, you will not be permitted to exchange those shares into another fund for 30 calendar days, although you may redeem those shares at any time. An exchange order received prior to the expiration of the 30-day period will not be honored.

By calling CMS, shareholders or their FSF of record may exchange among accounts with identical registrations, provided that the shares are held on deposit. During periods of unusual market changes or shareholder activity, shareholders may experience delays in contacting CMS by telephone to exercise the telephone exchange privilege. Because an exchange involves a redemption and reinvestment in another fund, completion of an exchange may be delayed under unusual circumstances, such as if the Fund suspends repurchases or postpones payment for the Fund shares being exchanged in accordance with federal securities law. CMS will also make exchanges upon receipt of a written exchange request and share certificates, if any. If the shareholder is a corporation, partnership, agent, or surviving joint owner, CMS may require customary additional documentation. Prospectuses of the other Funds are available from the CMD Literature Department by calling 1-800-426-3750.

A loss to a shareholder may result from an unauthorized transaction reasonably believed to have been authorized. No shareholder is obligated to use the telephone to execute transactions.

57

Consult your FSF or CMS. In all cases, the shares to be exchanged must be registered on the records of the Fund in the name of the shareholder desiring to exchange.

Shareholders of the other open-end funds generally may exchange their shares at NAV for the same class of shares of the Fund. Sales charges may apply for exchanges from money market funds.

An exchange is generally a capital sale transaction for federal income tax purposes. The exchange privilege may be revised, suspended or terminated at any time.

SUSPENSION OF REDEMPTIONS

A Fund may not suspend shareholders' right of redemption or postpone payment for more than seven days unless the Exchange is closed for other than customary weekends or holidays, or if permitted by the rules of the SEC during periods when trading on the Exchange is restricted or during any emergency which makes it impracticable for the Fund to dispose of its securities or to determine fairly the value of its net assets, or during any other period permitted by order of the SEC for the protection of investors.

SHAREHOLDER LIABILITY

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Declaration disclaims shareholder liability for acts or obligations of the Fund and the Trust and requires that notice of such disclaimer be given in each agreement, obligation, or instrument entered into or executed by the Fund or the Trust's Trustees. The Declaration provides for indemnification out of Fund property for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances (which are considered remote) in which the Fund would be unable to meet its obligations and the disclaimer was inoperative.

The risk of a particular fund incurring financial loss on account of another fund of the Trust is also believed to be remote, because it would be limited to circumstances in which the disclaimer was inoperative and the other fund was unable to meet its obligations.

SHAREHOLDER MEETINGS

The Trust is not required to hold annual shareholder meetings, but special meetings may be called for certain purposes. The Trust has voluntarily undertaken to hold a shareholder meeting at which the Board of Trustees would be elected at least every five years beginning in 2005. Each whole share (or fractional share) outstanding on the record date established in accordance with the Trust's By-Laws shall be entitled to a number of votes on any matter on which it is entitled to vote equal to the net asset value of the shares (or fractional share) in United States dollars determined at the close of business on the record date (for example, a share having a net asset value of $10.50 would be entitled to 10.5 votes).

The Trustees may fill any vacancies in the Board of Trustees except that the Trustees may not fill a vacancy if, immediately after filling such vacancy, less than two-thirds of the Trustees then in office would have been elected to such office by the shareholders. In addition, at such times as less than a majority of the Trustees then in office have been elected to such office by the shareholders, the Trustees must call a meeting of shareholders. Trustees may be removed from office by a written consent signed by a majority of the outstanding shares of the Trust or by a vote of the holders of a majority of the outstanding shares at a meeting duly called for the purpose. Except as otherwise disclosed in the Prospectus and this SAI, the Trustees shall continue to hold office and may appoint their successors.

At any shareholders' meetings that may be held, shareholders of all series would vote together, irrespective of series, on the election of Trustees, but each series would vote separately from the others on other matters, such as changes in the investment policies of that series or the approval of the management agreement for that series. Shares of each Fund and any other series of the Trust that may be in existence from time to time generally vote together except when required by law to vote separately by fund or by class.

APPENDIX I
DESCRIPTION OF BOND RATINGS
STANDARD & POOR'S (S&P)

The following descriptions are applicable to municipal bond funds:

AAA bonds have the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA bonds have a very strong capacity to pay interest and repay principal, and they differ from AAA only in small degree.

A bonds have a strong capacity to pay interest and repay principal, although they are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB bonds are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal than for bonds in the A category.

BB, B, CCC, CC and C bonds are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. BB indicates the lowest degree of speculation and C the highest degree. While such debt will likely have some quality and protective characteristics, these are outweighed by large uncertainties or large exposures to adverse conditions.

BB bonds have less near-term vulnerability to default than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The BB rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BBB- rating.

B bonds have a greater vulnerability to default but currently have the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied BB or BB- rating.

CCC bonds have a currently identifiable vulnerability to default, and are dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, the bonds are not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating.

CC rating typically is applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating.

C rating typically is applied to debt subordinated to senior debt which assigned an actual or implied CCC- debt rating. The C rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued.

CI rating is reserved for income bonds on which no interest is being paid.

D bonds are in payment default. The D rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized.

Plus(+) or minus(-) ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

PROVISIONAL RATINGS. The letter "p" indicates that the rating is provisional. A provisional rating assumes the successful completion of the project being financed by the debt being rated and indicates that payment of debt service requirements is largely or entirely dependent upon the successful and timely completion of the project. This rating, however, although addressing credit quality subsequent to completion of the project, makes no comments on the likelihood of, or the risk of default upon failure of, such completion. The investor should exercise his own judgment with respect to such likelihood and risk.

MUNICIPAL NOTES:

SP-1. Notes rated SP-1 have very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are designated as SP-1+.

SP-2. Notes rated SP-2 have satisfactory capacity to pay principal and interest.

59

Notes due in three years or less normally receive a note rating. Notes maturing beyond three years normally receive a bond rating, although the following criteria are used in making that assessment:

Amortization schedule (the larger the final maturity relative to other maturities, the more likely the issue will be rated as a note).

Source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be rated as a note).

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity, and the commercial paper rating symbols are usually used to denote the put (demand) option (for example, AAA/A-1+). Normally, demand notes receive note rating symbols combined with commercial paper symbols (for example, SP-1+/A-1+).

COMMERCIAL PAPER:

A. Issues assigned this highest rating are regarded as having the greatest capacity for timely payment. Issues in this category are further refined with the designations 1, 2, and 3 to indicate the relative degree to safety.

A-1. This designation indicates that the degree of safety regarding timely payment is either overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics are designed A-1+.

CORPORATE BONDS:

The description of the applicable rating symbols and their meanings is substantially the same as the Municipal Bond ratings set forth above.

The following descriptions are applicable to equity and taxable bond funds:

AAA bonds have the highest rating assigned by S&P. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA bonds differ from the highest rated obligations only in small degree. The obligor's capacity to meet its financial commitment on the obligation is very strong.

A bonds are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

BBB bonds exhibit adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB, B, CCC and CC bonds are regarded, as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB bonds are less vulnerable to non-payment than other speculative issues. However, they face major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitment on the obligation.

B bonds are more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

CCC bonds are currently vulnerable to nonpayment, and are dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC bonds are currently highly vulnerable to nonpayment.

C ratings may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on the obligation are being continued.

D bonds are in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

60

Plus (+) or minus(-): The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

R This symbol is attached to the rating of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk, such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)

AAA bonds are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge". Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While various protective elements are likely to change, such changes as can be visualized are most unlikely to impair a fundamentally strong position of such issues.

AA bonds are judged to be of high quality by all standards. Together with Aaa bonds they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities.

Those bonds in the Aa through B groups that Moody's believes possess the strongest investment attributes are designated by the symbol Aa1, A1 and Baa1.

A bonds possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

BAA bonds are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact, have speculative characteristics as well.

BA bonds are judged to have speculative elements: their future cannot be considered as well secured. Often, the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B bonds generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

CAA bonds are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

CA bonds represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C bonds are the lowest rated class of bonds and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

CONDITIONAL RATINGS. Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting conditions attach. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

MUNICIPAL NOTES:

MIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

DEMAND FEATURE OF VARIABLE RATE DEMAND SECURITIES:

Moody's may assign a separate rating to the demand feature of a variable rate demand security. Such a rating may include:

VMIG 1. This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

61

VMIG 2. This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

VMIG 3. This designation denotes favorable quality. All security elements are accounted for, but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

COMMERCIAL PAPER:

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment capacity of rated issuers:

Prime-1 Highest Quality

Prime-2 Higher Quality

Prime-3 High Quality

If an issuer represents to Moody's that its Commercial Paper obligations are supported by the credit of another entity or entities, Moody's, in assigning ratings to such issuers, evaluates the financial strength of the indicated affiliated corporations, commercial banks, insurance companies, foreign governments, or other entities, but only as one factor in the total rating assessment.

CORPORATE BONDS:

The description of the applicable rating symbols (Aaa, Aa, A) and their meanings is identical to that of the Municipal Bond ratings as set forth above, except for the numerical modifiers. Moody's applies numerical modifiers 1, 2, and 3 in the Aa and A classifications of its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a midrange ranking; and the modifier 3 indicates that the issuer ranks in the lower end of its generic rating category.

FITCH INC.

INVESTMENT GRADE BOND RATINGS

AAA bonds are considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong ability to pay interest and/or dividends and repay principal, which is unlikely to be affected by reasonably foreseeable events.

AA bonds are considered to be investment grade and of very high credit quality. The obligor's ability to pay interest and repay principal is very strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable future developments, short-term debt of these issuers is generally rated 'F-1+'.

A bonds are considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than debt securities with higher ratings.

BBB bonds are considered to be investment grade and of satisfactory credit quality. The obligor's ability to pay interest or dividends and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse impact on these securities and, therefore, impair timely payment. The likelihood that the ratings of these bonds will fall below investment grade is higher than for securities with higher ratings.

CONDITIONAL

A conditional rating is premised on the successful completion of a project or the occurrence of a specific event.

SPECULATIVE-GRADE BOND RATINGS

BB bonds are considered speculative. The obligor's ability to pay interest and repay principal may be affected over time by adverse economic changes. However, business and financial alternatives can be identified, which could assist the obligor in satisfying its debt service requirements.

B bonds are considered highly speculative. While securities in this class are currently meeting debt service requirements, the probability of continued timely payment of principal and interest reflects the obligor's limited margin of safety and the need for reasonable business and economic activity throughout the life of the issue.

CCC bonds have certain identifiable characteristics that, if not remedied, may lead to default. The ability to meet obligations requires an advantageous business and economic environment.

CC bonds are minimally protected. Default in payment of interest and/or principal seems probable over time.

C bonds are in imminent default in payment of interest or principal.

62

DDD, DD, AND D bonds are in default on interest and/or principal payments. Such securities are extremely speculative and should be valued on the basis of their ultimate recovery value in liquidation or reorganization of the obligor. 'DDD' represents the highest potential for recovery on these securities, and 'D' represents the lowest potential for recovery.

APPENDIX II

COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA")
PROXY VOTING POLICIES AND PROCEDURES
ADOPTED JULY 1, 2003 AND REVISED MARCH 4, 2005

POLICY:

ALL PROXIES(1) REGARDING CLIENT SECURITIES FOR WHICH COLUMBIA MANAGEMENT ADVISORS, LLC ("CMA") HAS ASSUMED AUTHORITY TO VOTE SHALL, UNLESS CMA DETERMINES IN ACCORDANCE WITH POLICIES STATED BELOW TO ABSTAIN FROM VOTING, BE VOTED IN A MANNER CONSIDERED BY CMA TO BE IN THE BEST INTEREST OF CMA'S CLIENTS, INCLUDING THE CMG FAMILY FUNDS(2) AND THEIR SHAREHOLDERS, WITHOUT REGARD TO ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES. THE BEST INTEREST OF CLIENTS IS DEFINED FOR THIS PURPOSE AS THE INTEREST OF ENHANCING OR PROTECTING THE ECONOMIC VALUE OF CLIENT ACCOUNTS, CONSIDERED AS A GROUP RATHER THAN INDIVIDUALLY, AS CMA DETERMINES IN ITS SOLE AND ABSOLUTE DISCRETION. IN THE EVENT A CLIENT BELIEVES THAT ITS OTHER INTERESTS REQUIRE A DIFFERENT VOTE, CMA SHALL VOTE AS THE CLIENT CLEARLY INSTRUCTS, PROVIDED CMA RECEIVES SUCH INSTRUCTIONS IN TIME TO ACT ACCORDINGLY.

CMA ENDEAVORS TO VOTE, IN ACCORDANCE WITH THIS POLICY, ALL PROXIES OF WHICH IT BECOMES AWARE, SUBJECT TO THE FOLLOWING EXCEPTIONS (UNLESS OTHERWISE AGREED) WHEN CMA EXPECTS TO ROUTINELY ABSTAIN FROM VOTING:

1. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE THE SECURITY HAS BEEN LOANED FROM THE CLIENT'S ACCOUNT.

2. PROXIES WILL USUALLY NOT BE VOTED IN CASES WHERE CMA DEEMS THE COSTS TO THE CLIENT AND/OR THE ADMINISTRATIVE INCONVENIENCE OF VOTING THE SECURITY (E.G., SOME FOREIGN SECURITIES) OUTWEIGH THE BENEFIT OF DOING SO.

CMA SEEKS TO AVOID THE OCCURRENCE OF ACTUAL OR APPARENT MATERIAL CONFLICTS OF INTEREST IN THE PROXY VOTING PROCESS BY VOTING IN ACCORDANCE WITH PREDETERMINED VOTING GUIDELINES, AS STATED BELOW. FOR THOSE PROXY PROPOSALS THAT REQUIRE SPECIAL CONSIDERATION OR IN INSTANCES WHERE SPECIAL CIRCUMSTANCES MAY REQUIRE VARYING FROM THE PREDETERMINED GUIDELINES, THE CMG PROXY COMMITTEE WILL DETERMINE THE BEST INTEREST OF CMA'S CLIENTS AND VOTE ACCORDINGLY, WITHOUT CONSIDERATION OF ANY RESULTING BENEFIT OR DETRIMENT TO CMA OR ITS AFFILIATES.

OVERVIEW:

CMA's policy is based upon its fiduciary obligation to act in its clients' best interest. Citing this obligation, the SEC has adopted rules pursuant to the Investment Advisers Act of 1940 and Investment Company Act of 1940 with respect to proxy voting.

PROCEDURE:

I. ACCOUNT POLICIES

Except as otherwise directed by the client, CMA shall vote as follows:

SEPARATELY MANAGED ACCOUNTS

CMA shall vote proxies on securities held in its separately managed accounts.

COLUMBIA TRUST COMPANY (CTC) TRUST POOLS

CMA shall vote proxies on securities held in the trust pools.

CMG FAMILY FUNDS/CMA FUND TRUST

CMA shall vote proxies on securities held in the Funds, including multi-managed and subadvised Funds.

COLUMBIA PRIVATE PORTFOLIO

CMA shall vote proxies on securities held in its separately managed accounts.

ALTERNATIVE INVESTMENT GROUP


(1) The term "proxy" as used herein refers to consents, elections and authorizations solicited by any party with respect to securities of any sort.

(2) A CMG Family Fund or a Fund is a registered investment company or series of a registered investment company managed or advised by Columbia Management Advisors, LLC

64

CMA's clients may invest in securities ("Alternative Investments") issued by alternative investment vehicles (i.e. hedge funds, private equity funds, and other alternative investment pools) that are structured as private limited partnerships ("LPs"), limited liability companies ("LLCs") or offshore corporations. Generally, CMA's Alternative Investment Group ("AIG") is the platform through which CMA provides advisory services relating to Alternative Investments.

The voting rights of Alternative Investments generally are rights of contract set forth in the limited liability company or limited partnership agreement, in the case of LLCs and LPs, or Memorandum and Articles of Association or By-laws, in the case of offshore corporations. Also, as privately placed securities, Alternative Investments generally are not subject to the regulatory scheme applicable to public companies. Consequently, in most cases, proxies are not solicited regarding Alternative Investment vehicles. Instead, consents may be solicited from members, limited partners or shareholders.

Because of the unique characteristics of Alternative Investments, CMA has a tailored process for voting Alternative Investment proxies and consents.

Process

AIG will vote all Alternative Investment proxies and consents in accordance with this Policy. The committee voting AIG proxies consists of AIG senior management, investment and operations professionals. Conflicts of interest are to be monitored and resolved as set forth in this Policy.

II. PROXY COMMITTEE

CMA shall establish a Proxy Committee whose standing members shall include the head of core equity, head of value, head of growth, head of income strategies, head of equity research and head of fixed income research. Each standing member may designate a senior portfolio manager or a senior analyst officer to act as a substitute in a given matter on their behalf.

The Proxy Committee's functions shall include, in part,

(a) direction of the vote on proposals where there has been a recommendation to the Committee, pursuant to Section IV.B, not to vote according to the predetermined Voting Guidelines stated in Section IV.A or on proposals which require special, individual consideration in accordance with Section IV.C;

(b) review at least annually of this Proxy Voting Policy and Procedure to ensure consistency with internal policies, client disclosures and regulatory requirements;

(c) review at least annually of existing Voting Guidelines and need for development of additional Voting Guidelines to assist in the review of proxy proposals; and

(d) development and modification of Voting Procedures, as stated in Section V, as it deems appropriate or necessary.

The Proxy Committee shall establish a charter, which shall set forth the Committee's purpose, membership and operation. The Committee's charter shall be consistent, in all material respects, with this policy and procedure.

III. CONFLICTS OF INTEREST

WITH OTHER BANK OF AMERICA BUSINESSES

Bank of America Corporation ("BAC"), the ultimate corporate parent of CMA, Bank of America, N.A. and all of their numerous affiliates owns, operates and has interests in many lines of business that may create or give rise to the appearance of a conflict of interest between BAC or its affiliates and those of Firm-advised clients. For example, the commercial and investment banking business lines may have interests with respect to issuers of voting securities that could appear to or even actually conflict with CMA's duty, in the proxy voting process, to act in the best economic interest of its clients.

Within CMA

Conflicts of interest may also arise from the business activities of CMA. For example, CMA might manage (or be seeking to manage) the assets of a benefit plan for an issuer. CMA may also be presented with an actual or apparent conflict of interest where proxies of securities issued by BAC or a CMG Family Fund, for which CMA serves as investment adviser, are to be voted for a client's account.

Management of Conflicts

CMA's policy is to always vote proxies in the best interest of its clients, as a whole, without regard to its own self-interest or that of its affiliates. BAC as well as CMA has various compliance policies and procedures in place in order to address any material conflicts of interest that might arise in this context.

65

1. BAC's enterprise-wide Code of Ethics specifically prohibits the flow of certain business-related information between associates on the commercial and/or investment banking side of the corporation and associates charged with trust or (as in the case of BACAP associates) non-trust fiduciary responsibilities, including investment decision-making and proxy voting.

2. In addition, BAC has adopted "Global Policies and Procedures Regarding Information Walls and Inside Information." Pursuant to these policies and procedures, "information barriers" have been established between various BAC business lines designed to prohibit the passage of certain information across those barriers.

3. Within CMA, CMA's Code of Ethics affirmatively requires that associates of CMA act in a manner whereby no actual or apparent conflict of interest may be seen as arising between the associate's interests and those of CMA's Clients.

4. By assuming his or her responsibilities pursuant to this Policy, each member of the Proxy Committee and any CMA or BAC associate advising or acting under the supervision or oversight of the Proxy Committee undertakes:

- To disclose to the chairperson of the Proxy Committee and the chairperson to the head of CMG Compliance any actual or apparent personal material conflicts of interest which he or she may have (e.g., by way of substantial ownership of securities, relationships with nominees for directorship, members of an issuer's or dissident's management or otherwise) in determining whether or how CMA shall vote proxies. In the event the chairperson of the Proxy Committee has a conflict of interest regarding a given matter, he or she shall abstain from participating in the Committee's determination of whether and/or how to vote in the matter; and

- To refrain from taking into consideration, in the decision as to whether or how CMA shall vote proxies:

- The existence of any current or prospective material business relationship between CMA, BAC or any of their affiliates, on one hand, and any party (or its affiliates) that is soliciting or is otherwise interested in the proxies to be voted, on the other hand; and/or

- Any direct, indirect or perceived influence or attempt to influence such action which the member or associate views as being inconsistent with the purpose or provisions of this Policy or the Code of Ethics of CMA or BAC.

Where a material conflict of interest is determined to have arisen in the proxy voting process that may not be adequately mitigated by voting in accordance with the predetermined Voting Guidelines, CMA's policy is to invoke one or more of the following conflict management procedures:

1. Convene the Proxy Committee for the purpose of voting the affected proxies in a manner that is free of the conflict.

2. Causing the proxies to be voted in accordance with the recommendations of a qualified, independent third party, which may include CMA's proxy voting agent.

3. In unusual cases, with the Client's consent and upon ample notice, forwarding the proxies to CMA's clients so that they may vote the proxies directly.

IV. VOTING GUIDELINES

A. THE PROXY COMMITTEE HAS ADOPTED THE FOLLOWING GUIDELINES FOR VOTING PROXIES:

1. Matters Relating to the Board of Directors/Corporate Governance

CMA generally will vote FOR:

- Proposals for the election of directors or for an increase or decrease in the number of directors, provided that no more than one-third of the Board of Directors would, presently or at any time during the previous three-year period, be from management.

However, CMA generally will WITHHOLD votes from pertinent director nominees if:

(i) the board as proposed to be constituted would have more than one-third of its members from management;

(ii) the board does not have audit, nominating, and compensation committees composed solely of directors who qualify as being regarded as "independent," i.e. having no material relationship, directly or indirectly, with the Company, as CMA's proxy voting agent may determine (subject to the Proxy Committee's contrary determination of independence or non-independence);

66

(iii) the nominee, as a member of the audit committee, permitted the company to incur excessive non-audit fees (as defined below regarding other business matters -- ratification of the appointment of auditors);

(iv) a director serves on more than six public company boards;

(v) the CEO serves on more than two public company boards other than the company's board.

On a CASE-BY-CASE basis, CMA may WITHHOLD votes for a director nominee who has failed to observe good corporate governance practices or, through specific corporate action or inaction (e.g. failing to implement policies for which a majority of shareholders has previously cast votes in favor), has demonstrated a disregard for the interests of shareholders.

- Proposals requesting that the board audit, compensation and/or nominating committee be composed solely of independent directors. The Audit Committee must satisfy the independence and experience requirements established by the Securities and Exchange Commission ("SEC") and the New York Stock Exchange, or appropriate local requirements for foreign securities. At least one member of the Audit Committee must qualify as a "financial expert" in accordance with SEC rules.

- Proposals to declassify a board, absent special circumstances that would indicate that shareholder interests are better served by a classified board structure.

CMA generally will vote FOR:

- Proposals to create or eliminate positions or titles for senior management. CMA generally prefers that the role of Chairman of the Board and CEO be held by different persons unless there are compelling reasons to vote AGAINST a proposal to separate these positions, such as the existence of a counter-balancing governance structure that includes at least the following elements in addition to applicable listing standards:

- Established governance standards and guidelines.

- Full board composed of not less than two-thirds "independent" directors, as defined by applicable regulatory and listing standards.

- Compensation, as well as audit and nominating (or corporate governance) committees composed entirely of independent directors.

- A designated or rotating presiding independent director appointed by and from the independent directors with the authority and responsibility to call and preside at regularly and, as necessary, specially scheduled meetings of the independent directors to be conducted, unless the participating independent directors otherwise wish, in executive session with no members of management present.

- Disclosed processes for communicating with any individual director, the presiding independent director (or, alternatively, all of the independent directors, as a group) and the entire board of directors, as a group.

- The pertinent class of the Company's voting securities has out-performed, on a three-year basis, both an appropriate peer group and benchmark index, as indicated in the performance summary table of the Company's proxy materials. This requirement shall not apply if there has been a change in the Chairman/CEO position within the three-year period.

- Proposals that grant or restore shareholder ability to remove directors with or without cause.

- Proposals to permit shareholders to elect directors to fill board vacancies.

- Proposals that encourage directors to own a minimum amount of company stock.

- Proposals to provide or to restore shareholder appraisal rights.

- Proposals to adopt cumulative voting.

- Proposals for the company to adopt confidential voting.

CMA generally will vote AGAINST:

- Proposals to classify boards, absent special circumstances indicating that shareholder interests would be better served by a classified board structure.

- Proposals that give management the ability to alter the size of the board without shareholder approval.

67

- Proposals that provide directors may be removed only by supermajority vote.

- Proposals to eliminate cumulative voting.

- Proposals which allow more than one vote per share in the election of directors.

- Proposals that provide that only continuing directors may elect replacements to fill board vacancies.

- Proposals that mandate a minimum amount of company stock that directors must own.

- Proposals to limit the tenure of non-management directors.

CMA will vote on a CASE-BY-CASE basis in contested elections of directors.

CMA generally will vote on a CASE-BY-CASE basis on board approved proposals relating to corporate governance. Such proposals include, but are not limited to:

- Director and officer indemnification and liability protection. CMA is opposed to entirely eliminating directors' and officers' liability for monetary damages for violating the duty of care. CMA is also opposed to expanding coverage beyond just legal expenses to acts, such as negligence, that are more serious violations of fiduciary obligation than mere carelessness. CMA supports proposals which provide such expanded coverage in cases when a director's or officer's legal defense was unsuccessful if: (i) the director was found to have acted in good faith and in a manner that he/she reasonably believed was in the best interests of the company, AND (ii) if the director's legal expenses would be covered.

- Reimbursement of proxy solicitation expenses taking into consideration whether or not CMA was in favor of the dissidents.

- Proxy contest advance notice. CMA generally will vote FOR proposals that allow shareholders to submit proposals as close to the meeting date as possible while allowing for sufficient time for Company response, SEC review, and analysis by other shareholders.

2. Compensation

CMA generally will vote FOR management sponsored compensation plans (such as bonus plans, incentive plans, stock option plans, pension and retirement benefits, stock purchase plans or thrift plans) if they are consistent with industry and country standards. However, CMA generally is opposed to compensation plans that substantially dilute ownership interest in a company, provide participants with excessive awards, or have objectionable structural features. Specifically, for equity-based plans, if the proposed number of shares authorized for option programs (excluding authorized shares for expired options) exceeds an average of 10% of the currently outstanding shares over the previous three years or an average of 3% over the previous three years for directors only, the proposal should be referred to the Proxy Committee. The Committee will then consider the circumstances surrounding the issue and vote in the best interest of CMA's clients. CMA requires that management provide substantial justification for the repricing of options.

CMA generally will vote FOR:

- Proposals requiring that executive severance arrangements be submitted for shareholder ratification.

- Proposals asking a company to expense stock options.

- Proposals to put option repricings to a shareholder vote.

- Employee stock purchase plans that have the following features: (i) the shares purchased under the plan are acquired for no less than 85% of their market value, (ii) the offering period under the plan is 27 months or less, and (iii) dilution is 10% or less.

CMA generally will vote AGAINST:

- Stock option plans that permit issuance of options with an exercise price below the stock's current market price, or that permit replacing or repricing of out-of-the money options.

- Proposals to authorize the replacement or repricing of out-of-the money options.

68

CMA will vote on a CASE-BY-CASE basis proposals regarding approval of specific executive severance arrangements.

3. Capitalization

CMA generally will vote FOR:

- Proposals to increase the authorized shares for stock dividends, stock splits (and reverse stock splits) or general issuance, unless proposed as an anti-takeover measure or a general issuance proposal increases the authorization by more than 30% without a clear need presented by the company. Proposals for reverse stock splits should include an overall reduction in authorization.

For companies recognizing preemptive rights for existing shareholders, CMA generally will vote FOR general issuance proposals that increase the authorized shares by more than 30%. CMA will vote on a CASE-BY-CASE basis all such proposals by companies that do not recognize preemptive rights for existing shareholders.

- Proposals for the elimination of authorized but unissued shares or retirement of those shares purchased for sinking fund or treasury stock.

- Proposals to institute/renew open market share repurchase plans in which all shareholders may participate on equal terms.

- Proposals to reduce or change the par value of common stock, provided the number of shares is also changed in order to keep the capital unchanged.

4. Mergers, Restructurings and Other Transactions

CMA will review, on a CASE-BY-CASE basis, business transactions such as mergers, acquisitions, reorganizations, liquidations, spinoffs, buyouts and sale of all or substantially all of a company's assets.

5. Anti-Takeover Measures

CMA generally will vote AGAINST proposals intended largely to avoid acquisition prior to the occurrence of an actual event or to discourage acquisition by creating a cost constraint. With respect to the following measures, CMA generally will vote as follows:

Poison Pills

- CMA votes FOR shareholder proposals that ask a company to submit its poison pill for shareholder ratification.

- CMA generally votes FOR shareholder proposals to eliminate a poison pill.

- CMA generally votes AGAINST management proposals to ratify a poison pill.

Greenmail

- CMA will vote FOR proposals to adopt anti-greenmail charter or bylaw amendments or to otherwise restrict a company's ability to make greenmail payments.

Supermajority vote

- CMA will vote AGAINST board-approved proposals to adopt anti-takeover measures such as supermajority voting provisions, issuance of blank check preferred stock, the creation of a separate class of stock with disparate voting rights and charter amendments adopting control share acquisition provisions.

Control Share Acquisition Provisions

- CMA will vote FOR proposals to opt out of control share acquisition statutes.

6. Other Business Matters

CMA generally will vote FOR:

- Proposals to approve routine business matters such as changing the company's name and procedural matters relating to the shareholder meeting such as approving the minutes of a prior meeting.

69

- Proposals to ratify the appointment of auditors, unless any of the following apply in which case CMA will generally vote AGAINST the proposal:

- Credible reason exists to question:

- The auditor's independence, as determined by applicable regulatory requirements.

- The accuracy or reliability of the auditor's opinion as to the company's financial position.

- Fees paid to the auditor or its affiliates for "non-audit" services were excessive, i.e., in excess of the total fees paid for "audit," "audit-related" and "tax compliance" and/or "tax return preparation" services, as disclosed in the company's proxy materials.

- Bylaw or charter changes that are of a housekeeping nature (e.g., updates or corrections).

- Proposals to approve the annual reports and accounts provided the certifications required by the Sarbanes Oxley Act of 2002 have been provided.

CMA generally will vote AGAINST:

- Proposals to eliminate the right of shareholders to act by written consent or call special meetings.

- Proposals providing management with authority to adjourn an annual or special shareholder meeting absent compelling reasons, or to adopt, amend or repeal bylaws without shareholder approval, or to vote unmarked proxies in favor of management.

- Shareholder proposals to change the date, time or location of the company's annual meeting of shareholders.

CMA will vote AGAINST:

- Authorization to transact other unidentified substantive (as opposed to procedural) business at a meeting.

CMA will vote on a CASE-BY-CASE basis:

- Proposals to change the location of the company's state of incorporation. CMA considers whether financial benefits (e.g., reduced fees or taxes) likely to accrue to the company as a result of a reincorporation or other change of domicile outweigh any accompanying material diminution of shareholder rights.

- Proposals on whether and how to vote on "bundled" or otherwise conditioned proposals, depending on the overall economic effects upon shareholders.

CMA generally will ABSTAIN from voting on shareholder proposals predominantly involving social, socio-economic, environmental, political or other similar matters on the basis that their impact on share value can rarely be anticipated with any high degree of confidence. CMA may, on a CASE-BY-CASE basis, vote:

- FOR proposals seeking inquiry and reporting with respect to, rather than cessation or affirmative implementation of, specific policies where the pertinent issue warrants separate communication to shareholders; and

- FOR or AGAINST the latter sort of proposal in light of the relative benefits and detriments (e.g. distraction, costs, other burdens) to share value which may be expected to flow from passage of the proposal.

7. Other Matters Relating to Foreign Issues

CMA generally will vote FOR:

- Most stock (scrip) dividend proposals. CMA votes AGAINST proposals that do not allow for a cash option unless management demonstrates that the cash option is harmful to shareholder value.

- Proposals to capitalize the company's reserves for bonus issues of shares or to increase the par value of shares.

- Proposals to approve control and profit transfer agreements between a parent and its subsidiaries.

- Management proposals seeking the discharge of management and supervisory board members, unless there is concern about the past actions of the company's auditors/directors and/or legal action is being taken against the board by other shareholders.

70

- Management proposals concerning allocation of income and the distribution of dividends, unless the dividend payout ratio has been consistently below 30 percent without adequate explanation or the payout is excessive given the company's financial position.

- Proposals for the adoption of financing plans if they are in the best economic interests of shareholders.

8. INVESTMENT COMPANY MATTERS

CMA will vote on a CASE-BY-CASE basis proposals for the election of directors, considering the following factors:

- Board structure

- Attendance at board and committee meetings.

CMA will WITHHOLD votes from directors who:

- Attend less than 75 percent of the board and committee meetings without a valid excuse for the absences. Valid reasons include illness or absence due to company business. Participation via telephone is acceptable. In addition, if the director missed only one meeting or one day's meetings, votes should not be withheld even if such absence dropped the director's attendance below 75 percent.

- Ignore a shareholder proposal that is approved by a majority of shares outstanding;

- Ignore a shareholder proposal this is approved by a majority of the votes cast for two consecutive years;

- Are interested directors and sit on the audit or nominating committee; or

B. ABILITY TO VOTE PROXIES OTHER THAN AS PROVIDED IN A ABOVE.

A Portfolio Manager, sub-adviser or other party involved with a client's account may conclude that the best interest of the firm's client, as defined above, requires that a proxy be voted in a manner that differs from the predetermined proxy Voting Guidelines stated in Section IV.A. In this situation, he or she shall request that the Proxy Committee consider voting the proxy other than according such Guidelines. If any person, group, or entity requests the Proxy Committee (or any of its members) vote a proxy other than according to the predetermined Voting Guidelines, that person shall furnish to the Proxy Committee a written explanation of the reasons for the request and a description of the person's, group's, or entity's relationship, if any, with the parties proposing and/or opposing the matter's adoption.

C. PROPOSALS REQUIRING SPECIAL CONSIDERATION

The following proposals require special, individual consideration. The Proxy Committee will determine how proxies related to all such proposals will be voted.

1. NEW PROPOSALS. For each new type of proposal that is expected to be proposed to shareholders of multiple companies, the Proxy Committee will develop a Voting Guideline which will be incorporated into this Policy.

2. ACCOUNTS ADHERING TO TAFT HARTLEY PRINCIPLES. All proposals for these accounts shall be voted according to the Taft Hartley Guidelines developed by Institutional Shareholder Services, Inc. ("ISS").

3. ACCOUNTS ADHERING TO SOCIALLY RESPONSIBLE PRINCIPLES. All proposals for these accounts shall be voted according to the Socially Responsible Guidelines developed by ISS or as specified by the client.

4. PROXIES OF INTERNATIONAL ISSUERS WHICH BLOCK SECURITIES SALES BETWEEN THE TIME A SHAREHOLDER SUBMITS A PROXY AND THE VOTE. Proposals for these securities shall be voted only on the specific instruction of the Proxy Committee and to the extent practicable in accordance with the Voting Guidelines set forth in this Policy.

5. PROXIES OF INVESTMENT COMPANY SHARES. Proposals on issues other than those specified in Section IV.A.

6. EXECUTIVE/DIRECTOR COMPENSATION. Except as provided in Section
IV.A, proposals relating to compensation of any executive or director will be voted as recommended by ISS or as otherwise directed by the Proxy Committee.

7. PREEMPTIVE RIGHTS. Proposals to create or eliminate shareholder preemptive rights. In evaluating these proposals the Proxy Committee will consider the size of the company and the nature of its shareholder base.

V. VOTING PROCEDURES

The Proxy Committee has developed the following procedures to aid the voting of proxies according to the Voting Guidelines set forth in Section IV above. The Proxy Committee may revise these procedures from time to time, as it deems necessary or appropriate to effect the purposes of this Policy.

- CMA shall use an independent, third-party vendor (currently Institutional Shareholder Services ("ISS")), to implement its proxy voting process as CMAs proxy voting agent. This retention is subject to CMA continuously assessing the vendor's independence from CMA and its affiliates, and the vendor's ability to perform its responsibilities (and, especially, its responsibility to vote client proxies in accordance with CMA's proxy voting guidelines) free of any actual, potential or apparent material conflicts of interests that may arise between the interests of the vendor, its affiliates, the vendor's other clients and the owners, officers or employees of any such firm, on the one hand, and CMA's clients, on the other hand. As means of performing this assessment, CMA will require various reports and notices from the vendor, as well as periodic audits of the vendor's voting record and other due diligence.

- ISS shall provide proxy analysis and record keeping services in addition to voting proxies on behalf of CMA in accordance with this Policy.

- On a daily basis CMA shall send to ISS a holdings file detailing each equity holding held in all accounts over which CMA has voting authority. Information regarding equity holdings for international portfolio shall be sent weekly.

- ISS shall receive proxy material information from Proxy Edge or the custodian bank for the account. This shall include issues to be voted upon, together with a breakdown of holdings for CMA accounts. ISS shall then reconcile information it receives from CMA with that it has received from Proxy Edge and custodian banks. Any discrepancies shall be promptly noted and resolved by ISS, with notice to CMA.

74

- Whenever a vote is solicited, ISS shall execute the vote according to CMA's Voting Guidelines previously delivered by CMA to ISS as set forth in Section IV.A.

- If ISS is not sure how to vote a particular proxy, then ISS will issue a request for voting instructions to CMA over a secure website. CMA personnel shall check this website regularly. The request shall be accompanied by a recommended vote. The recommended vote shall be based upon CMA's understanding of the Voting Guidelines previously delivered to ISS. CMA shall promptly provide ISS with any amendments or modifications to the Voting Guidelines if necessary. CMA shall return a final instruction to vote to ISS, which ISS shall record with Proxy Edge or the custodian bank as our agent.

- Each time that ISS shall send CMA a request to vote the request shall be accompanied by the recommended vote determined in accordance with CMA's Voting Guidelines. ISS shall vote as indicated in the request unless the client has reserved discretion, the Proxy Committee determines that the best interest of clients requires another vote or the proposal is a matter as to which the Proxy Committee affords special, individual consideration under Section IV.C. In such situations ISS shall vote based on the direction of the client or the Proxy Committee, as the case may be. The interests of CMA's Taft Hartley or Socially Responsible clients may impact a proposal that normally should be voted in a certain way. ISS shall inform CMA of all proposals having impact on its Taft Hartley and or Socially Responsible clients. The Proxy Voting Committee shall be consulted before a vote is placed in cases where Taft Hartley or Socially Responsible issues are presented.

- ISS shall have procedures in place to ensure that a vote is cast on every security holding maintained by CMA on which a vote is solicited unless otherwise directed by the Proxy Committee. On a yearly basis, or as required by our clients CMA shall receive a report from ISS detailing CMA's voting for the previous period.

VI. AVAILABILITY OF PROXY POLICY AND VOTING RECORD

A summary disclosure regarding the provisions of this Policy is available in CMA's Form ADV. Upon receipt of a Client's request for more information, CMA will provide to the Client a copy of this Policy and/or how CMA voted proxies for the Client pursuant to this Policy for up to a one-year period.

Item 24. Persons Controlled by or under Common Control with Registrant

None

Item 25. Indemnification

Article Five of the Bylaws of Registrant ("Article Five") provides that Registrant shall indemnify each of its trustees and officers (including persons who serve at the Registrant's request as directors, officers or trustees of another organization in which the Registrant has any interest as a shareholder, creditor or otherwise) who are not employees or officers of any investment adviser to the Registrant or any affiliated person thereof, and its chief compliance officer, regardless of whether such person is an employee or officer of any investment adviser to the Trust or any affiliated person thereof, and may indemnify each of its trustees and officers (including persons who serve at the Registrant's request as directors, officers or trustees of another organization in which the Registrant has any interest as a shareholder, creditor or otherwise) who are employees or officers of any investment adviser to the Registrant or any affiliated person thereof ("Covered Persons") under specified circumstances.


Section 17(h) of the Investment Company Act of 1940 ("1940 Act") provides that neither the Agreement and Declaration of Trust nor the By-Laws of Registrant, nor any other instrument pursuant to which Registrant is organized or administered, shall contain any provision which protects or purports to protect any trustee or officer of Registrant against any liability to Registrant or its shareholders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office. In accordance with Section 17(h) of the 1940 Act, Article Five shall not protect any person against any liability to Registrant or its shareholders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office. To the extent required under the 1940 Act, (i) Article Five does not protect any person against any liability to Registrant or to its shareholders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office; (ii) in the absence of a final decision on the merits by a court or other body before whom a proceeding was brought that a Covered Person was not liable by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office, no indemnification is permitted under Article Five unless a determination that such person was not so liable is made on behalf of Registrant by (a) the vote of a majority of the trustees who are neither "interested persons" of Registrant, as defined in Section 2(a)(19) of the 1940 Act, nor parties to the proceeding ("disinterested, non-party trustees"), or (b) an independent legal counsel as expressed in a written opinion; and (iii) Registrant will not advance attorneys' fees or other expenses incurred by a Covered Person in connection with a civil or criminal action, suit or proceeding unless Registrant receives an undertaking by or on behalf of the Covered Person to repay the advance (unless it is ultimately determined that he is entitled to indemnification) and (a) the Covered Person provides security for his undertaking, or (b) Registrant is insured against losses arising by reason of any lawful advances, or (c) a majority of the disinterested, non-party trustees of Registrant or an independent legal counsel as expressed in a written opinion, determine, based on a review of readily-available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the Covered Person ultimately will be found entitled to indemnification.

Any approval of indemnification pursuant to Article Five does not prevent the recovery from any Covered Person of any amount paid to such Covered Person in accordance with Article Five as indemnification if such Covered Person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that such Covered Person's action was in, or not opposed to, the best interests of Registrant or to have been liable to Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of such Covered Person's office.

Article Five also provides that its indemnification provisions are not exclusive. The Trust has also entered into Indemnification Agreements with each of its Trustees and its chief compliance officer, a copy of which has been filed as an exhibit to this


registration statement, establishing certain procedures with respect to the indemnification described above.

Such consent shall be treated for all purposes as a vote taken at a meeting of Trustees.

2.7 Presence through Communications Equipment.

ARTICLE 5

INDEMNIFICATION

5.1 Trustees, Officers, etc. The Trust shall indemnify each of its Trustees and officers (including persons who serve at the Trust's request as directors, officers or Trustees of another organization in which the Trust has any interest as a shareholder, creditor or otherwise) who are not employees or officers of any investment adviser to the Trust or any affiliated person thereof and its chief compliance officer, regardless of whether such person is an employee or officer of any investment adviser to the Trust or any affiliated person thereof, and may indemnify each of its other Trustees and officers (including persons who serve at the Trust's request as directors, officers or Trustees of another organization in which the Trust has any interest as a shareholder, creditor or otherwise) (i.e., those who are employees or officers of any investment adviser to the Trust or any affiliated person thereof) (hereinafter referred to as a "Covered Person") against all liabilities and expenses, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by any Covered Person, in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such Covered Person may be or may have been threatened, while in office or thereafter, by reason of any alleged act or omission as a Trustee or officer or by reason of his or her being or having been

-4-

such a Covered Person except with respect to any matter as to which such Covered Person shall have been finally adjudicated in any such action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and except that no Covered Person shall be indemnified against any liability to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office. Expenses, including counsel fees, so incurred by any such Covered Person (but excluding amounts paid in satisfaction of judgments, in compromise or as fines or penalties) shall be paid from time to time by the Trust in advance of the final disposition of any such action, suit or proceeding upon receipt of an undertaking by or on behalf of such Covered Person to repay amounts so paid to the Trust if it is ultimately determined that indemnification of such expenses is not authorized under this Article, provided, however, that either (a) such Covered Person shall have provided appropriate security for such undertaking, (b) the Trust shall be insured against losses arising from any such advance payments or (c) either a majority of the disinterested Trustees acting on the matter (provided that a majority of the disinterested Trustees then in office act on the matter), or independent legal counsel in a written opinion, shall have determined, based upon a review of readily available facts (as opposed to a full trial type inquiry) that there is reason to believe that such Covered Person will be found entitled to indemnification under this Article. For purposes of the determination or opinion referred to in clause (c), the majority of disinterested Trustees acting on the matter or independent legal counsel, as the case may be, shall afford the Covered Person a rebuttable presumption that the Covered Person has not engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office.

5.2 Compromise Payment. As to any matter disposed of (whether by a compromise payment, pursuant to a consent decree or otherwise) without an adjudication by a court, or by any other body before which the proceeding was brought, that such Covered Person has not acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust or is liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office, indemnification shall be provided if (a) approved, after notice that it involves such indemnification, by at least a majority of the disinterested Trustees acting on the matter (provided that a majority of the disinterested Trustees then in office act on the matter) upon a determination, based upon a review of readily available facts (as opposed to a full trial type inquiry) that such Covered Person has acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and is not liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office, or (b) there has been obtained an opinion in writing of independent legal counsel, based upon a review of readily available facts (as opposed to a full trial type inquiry) to the effect that such Covered Person appears to have acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and that such indemnification would not protect such Covered Person against any liability to the Trust to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office. Any approval pursuant to this Section shall not prevent the recovery from any Covered Person of any amount paid to such Covered Person in accordance with this
Section as indemnification if such Covered Person is subsequently

-5-

adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that his or her action was in the best interests of the Trust or to have been liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office.

5.3 Indemnification Not Exclusive. The right of indemnification hereby provided shall not be exclusive of or affect any other rights to which any such Covered Person may be entitled. As used in this Article 5, the term "Covered Person" shall include such person's heirs, executors and administrators; and a "disinterested Trustee" is a Trustee who is not an "interested person" of the Trust as defined in Section 2(a)(19) of the Investment Company Act of 1940 (or exempted from being an "interested person" by any rule, regulation or order of the Securities and Exchange Commission) and against whom none of the actions, suits or other proceedings in question or another action, suit or other proceeding on the same or similar grounds is then or has been pending. Nothing contained in this Article shall affect any rights to indemnification to which personnel of the Trust, other than Trustees and officers, and other persons may be entitled by contract or otherwise under law, nor the power of the Trust to purchase and maintain liability insurance on behalf of any such person.

ARTICLE 6

REPORTS

6.1 General. The Trustees and officers shall render reports at the time and in the manner required by the Declaration of Trust or any applicable law. Officers shall render such additional reports as they may deem desirable or as may from time to time be required by the Trustees.

ARTICLE 7

SEAL

7.1 General. The seal of the Trust shall consist of a flat-faced die with the word "Massachusetts," together with the name of the Trust and the year of its organization cut or engraved thereon, but, unless otherwise required by the Trustees, the seal shall not be necessary to be placed on, and its absence shall not impair the validity of, any document, instrument or other paper executed and delivered by or on behalf of the Trust.

ARTICLE 8

EXECUTION OF PAPERS

8.1 General.

This Agreement is made as of the __ day of March, 2006 between COLUMBIA FUNDS SERIES TRUST I (the "Trust"), on behalf of its COLUMBIA BALANCED FUND series, (the "Fund") and COLUMBIA MANAGEMENT ADVISORS, LLC (the "Adviser"). The Trust is registered as an open-end investment company pursuant to the Investment Company Act of 1940 (the "Act"). The Adviser is registered as an investment adviser pursuant to the Investment Advisers Act of 1940. This Agreement relates to services to be performed by the Adviser with respect to the Fund.

The parties agree as follows:

1. DUTIES OF ADVISER. The Adviser shall regularly provide the Fund with research, advice, and supervision with respect to investment matters and shall furnish continuously an investment program, recommend what securities shall be purchased or sold and what portion of the Fund's assets shall be held invested or uninvested, subject always to the provisions of the Act and the Fund's Articles of Incorporation and Bylaws, and amendments thereto, which amendments shall be furnished to the Adviser by the Fund. The Adviser shall take any steps necessary or appropriate to carry out its decisions in regard to the foregoing matters and the general conduct of the business of the Fund. The Adviser may take into consideration receipt of research and statistical information and other services rendered to the Fund in the allocation of commissions from portfolio brokerage business.

(a) The Adviser shall pay or reimburse the Fund for payments made by the Fund for all executive salaries and executive expenses, office rent of the Fund, ordinary office expenses (other than the expense of clerical services relating to the administration of the Fund), and for any other expenses that, if otherwise borne by the Fund, would cause the Fund to "be deemed to be acting as a distributor of securities of which it is the issuer, other than through an underwriter," pursuant to Rule 12b-1 under the Act. The Adviser shall provide investment advisory, statistical, and research facilities and all clerical services relating to research, statistical, and investment work with respect to the Fund.

(b) The Adviser shall not be required to pay any expenses of the Fund other than those enumerated in this Agreement. The Fund will assume all other costs, including the cost of its custodian, legal, auditing, and accounting expenses, disinterested directors' fees, taxes, and governmental fees, interest, brokers' commissions, transaction expenses, cost of stock certificates, and any other expenses (including clerical expenses) of issue, sale, repurchase, or redemption of shares, expenses of registering or qualifying shares for sale, transfer taxes, and all expenses of preparing the Fund's registration statement and prospectus, and the cost of printing and delivering to shareholders prospectuses and reports.

(c) At the request of the Fund, the Adviser shall pay all or a portion of the direct and indirect costs, charges and expenses of or related to the Fund's business and operations. The Adviser will submit to the Fund on a monthly basis a statement setting forth the cost, charges and expenses paid by the Adviser for the previous month. Upon receipt of the statement, the Fund shall promptly reimburse the Adviser for the costs, charges and expenses.

3. COMPENSATION OF THE ADVISER.

If the asset value is not required to be determined on any particular business day, then for the purposes of this Section 3, the asset value of a share as last determined shall be deemed to be the asset value of a share as of the close of business on that day. If there is no business day in any calendar month, the fee shall be computed on the basis of the asset value of a share as last determined, multiplied by the average number of shares outstanding on the last day of the month.

4. COVENANTS OF THE ADVISER. In connection with purchases or sales of portfolio securities for the account of the Fund, neither the Adviser nor any officer, director, or employee of the Adviser shall act as a principal.

1

the Adviser or any of its affiliates give any advice to clients concerning the shares of the Fund, it will act solely as investment counsel for the clients and not on behalf of the Fund.

5. LIMITATION ON LIABILITY OF ADVISER. The Adviser shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the matters to which this agreement relates, except a loss resulting from willful malfeasance, bad faith, or gross negligence on the part of the Adviser in the performance of its duties or from reckless disregard by the Adviser of its obligations and duties under this Agreement. The federal securities laws impose liabilities under certain circumstances on persons who act in good faith, and therefore nothing herein shall in any way constitute a waiver or limitation of any rights which the Fund may have under any federal securities laws.

6. DURATION AND TERMINATION OF THIS AGREEMENT.

(a) This Agreement shall remain in force for two years from the date hereof, and it may be continued from year to year thereafter if approved annually by a vote of a majority of the Fund's shareholders or by its Board of Directors and in either case a vote of a majority of the Board of Directors who are not parties to this Agreement or interested persons of any such party cast in person at a meeting called for the purpose of voting on such approval.

3. COMPENSATION OF THE ADVISER. For the services to be rendered, the facilities to be furnished, and the payments to be made by the Adviser, as provided in Sections 1 and 2 hereof, for each calendar month the Fund shall pay to the Adviser a fee computed at the annual rate of .75 of 1 percent of daily net assets. If the asset value is not required to be determined on any particular business day, then for the purposes of this Section 3, the asset value of a share as last determined shall be deemed to be the asset value of a share as of the close of business on that day. If there is no business day in any calendar month, the fee shall be computed on the basis of the asset value of a share as last determined, multiplied by the average number of shares outstanding on the last day of the month.

4. COVENANTS OF THE ADVISER. In connection with purchases or sales of portfolio securities for the account of the Fund, neither the Adviser nor any officer, director, or employee of the Adviser shall act as a principal.

If the Adviser or any of its affiliates give any advice to clients concerning the shares of the Fund, it will act solely as investment counsel for the clients and not on behalf of the Fund.

5. LIMITATION ON LIABILITY OF ADVISER. The Adviser shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the matters to which this agreement relates, except a loss resulting from willful malfeasance, bad faith, or gross negligence on the part of the Adviser in the performance of its duties or from reckless disregard by the Adviser of its obligations and duties under this Agreement. The federal securities laws impose liabilities under certain circumstances on persons who act in good faith, and therefore nothing herein shall in any way constitute a waiver or limitation of any rights which the Fund may have under any federal securities laws.

6. DURATION AND TERMINATION OF THIS AGREEMENT.

(a) This Agreement shall remain in force for two years from the date hereof, and it may be continued from year to year thereafter if approved annually by a vote of a majority of the Fund's shareholders or by its Board of Directors and in either case a vote of a majority of the Board of Directors who are not parties to this Agreement or interested persons of any such party cast in person at a meeting called for the purpose of voting on such approval.

(b) This Agreement may be terminated at any time without the payment of any penalty by vote of the Board of Directors of the Fund, by vote of a majority of the outstanding shares of the Fund, or by the Adviser, on 60 days written notice to the other party.

The parties agree as follows:

1. Investment Management Services. The Adviser shall manage the investment operations of the Trust and each Fund, subject to the terms of this Agreement and to the supervision and control of the Trust's Board of Trustees ("Trustees"). The Adviser agrees to perform, or arrange for the performance of, the following services with respect to each Fund:

(c) unless otherwise directed by the Trustees, to determine from time to time securities, commodities, interests or other investments to be purchased, sold, retained or lent by the Funds, and to implement those decisions, including the selection of entities with or through which such purchases, sales or loans are to be effected;

In connection with the selection of all such parties for the placement of all such orders, the Adviser shall attempt to obtain most favorable execution and price, but may nevertheless in its sole discretion as a secondary factor, purchase and sell portfolio securities from and to brokers and dealers who provide the Adviser with statistical, research and other information, analysis, advice, and similar services. In recognition of such services or brokerage services provided by a broker or dealer, the Adviser is hereby authorized to pay such broker or dealer a commission or spread in excess of that which

The Adviser may, where it deems to be advisable, aggregate orders for its other customers together with any securities of the same type to be sold or purchased for the Trust or one or more Funds in order to obtain best execution or lower brokerage commissions. In such event, the Adviser shall allocate the shares so purchased or sold, as well as the expenses incurred in the transaction, in a manner it considers to be equitable and fair and consistent with its fiduciary obligations to the Trust, the Funds, and the Adviser's other customers.

The Adviser shall for all purposes be deemed to be an independent contractor and not an agent of the Trust and shall, unless otherwise expressly provided or authorized, have no authority to act for or represent the Trust in any way.

2. Administrative Services. The Adviser shall supervise the business and affairs of the Trust and each Fund and shall provide such services and facilities as may be required for effective administration of the Trust and the Funds as are not provided by employees or other agents engaged by the Trust; provided that the Adviser shall not have any obligation to provide under this Agreement any such services which are the subject of a separate agreement or arrangement between the Trust and the Adviser, any affiliate of the Adviser, or any third party administrator ("Administrative Agreements").

3. Use of Affiliated Companies and Subcontractors. In connection with the services to be provided by the Adviser under this Agreement, the Adviser may, to the extent it deems appropriate, and subject to compliance with the requirements of applicable laws and regulations and upon receipt of written approval of the Trustees, make use of (i) its affiliated companies and their directors, trustees, officers, and employees and (ii) subcontractors selected by the Adviser, provided that the Adviser shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided by this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by the Adviser or such parties.

4. Expenses Borne by the Trust.

Without limitation, such costs and expenses shall include but not be limited to:

(a) all charges of depositories, custodians and other agencies for the safekeeping and servicing of its cash, securities, and other property;

2

(g) all expenses of printing of annual or more frequent revisions of the Trust's prospectus(es) and of supplying each then-existing Unitholder with a copy of a revised prospectus;

(m) all interest on indebtedness, if any, incurred by the Trust or a Fund; and

(n) all fees, dues and other expenses incurred by the Trust in connection with membership of the Trust in any trade association or other investment company organization.

5. Allocation of Expenses Borne by Trust. Any expenses borne by the Trust that are attributable solely to the organization, operation or business of a Fund shall be paid solely out of Fund assets. Any expense borne by the Trust which is not solely attributable to a Fund, nor solely to any other series of shares of the Trust, shall be apportioned in such manner as the Adviser determines is fair and appropriate, or as otherwise specified by the Board of Trustees.

6. Expenses Borne by the Adviser. The Adviser at its own expense shall furnish all executive and other personnel, office space, and office facilities required to render the investment management and administrative services set forth in this Agreement. The Adviser shall pay all expenses of establishing, maintaining, and servicing the accounts of Unitholders in each Fund. However, the Adviser shall not be required to pay or provide any credit for services provided by Trust's custodian or other agents without additional cost to the Trust.

In the event that the Adviser pays or assumes any expenses of Trust or a Fund not required to be paid or assumed by the Adviser under this Agreement, the Adviser shall not be obligated hereby to pay or assume the same or similar expense in the future; provided that nothing contained herein shall be deemed to relieve the Adviser of any obligation to the Trust or a Fund under any separate agreement or arrangement between the parties.

7. Management Fee. For the services rendered, facilities provided, and charges assumed and paid by the Adviser hereunder, the Trust shall pay to the Adviser out of the assets of each Fund fees at the annual rate for such Fund as set forth in Schedule A to this Agreement. For each Fund, the management fee shall accrue on each calendar day, and shall be payable monthly on the first business day of the next succeeding calendar month. The daily fee accrual shall be computed by multiplying the fraction of one divided by the number of days in the calendar year by the applicable annual rate of fee, and multiplying this product by the net assets of the Fund, determined in the manner established by the Board of Trustees, as of the close of business on the last preceding business day on which the Fund's net asset value was determined.

8. Retention of Sub-Adviser. Subject to obtaining the initial and periodic approvals required under Section 15 of the 1940 Act, the Adviser may retain one or more sub-advisers at the Adviser's own cost and expense for the purpose of furnishing one or more of the services described in Section 1 hereof with respect to the Trust or one or more Funds.

9. Non-Exclusivity. The services of the Adviser to the Trust hereunder are not to be deemed exclusive and the Adviser shall be free to render similar services to others.

11. Amendment. This Agreement may not be amended as to the Trust or any Fund without the affirmative votes (a) of a majority of the Board of Trustees, including a majority of those Trustees who are not "interested persons" of the Trust or of the Adviser, voting in person at a meeting called for the purpose of voting on such approval, and (b) of a "majority of the outstanding shares" of the Trust or, with respect to an amendment affecting an individual Fund, a "majority of the outstanding shares" of that Fund.

13. Ownership of Records; Interparty Reporting. All records required to be maintained and preserved by Trust pursuant to the provisions of rules or regulations of the Securities and Exchange Commission under Section 31(a) of the Act or other applicable laws or regulations which are maintained and preserved by the Adviser on behalf of the Trust and any other records the parties mutually agree shall be maintained by the Adviser on behalf of the Trust are the property of the Trust and shall be surrendered by the Adviser promptly on request by the Trust; provided that the Adviser may at its own expense make and retain copies of any such records.

The Trust shall furnish or otherwise make available to the Adviser such copies of the financial statements, proxy statements, reports, and other information relating to the business and affairs of each Unitholder in a Fund as the Adviser may, at any time or from time to time, reasonably require in order to discharge its obligations under this Agreement.

The Adviser shall prepare and furnish to the Trust as to each Fund statistical data and other information in such form and at such intervals as the Trust may reasonably request.

14. Non-Liability of Trustees and Unitholders. Any obligation of the Trust hereunder shall be binding only upon the assets of the Trust (or the applicable Fund thereof) and shall not be binding upon any Trustee, officer, employee, agent or Unitholder of the Trust.

FORM OF

COLUMBIA INCOME FUND
COLUMBIA INTERMEDIATE BOND FUND

MANAGEMENT AGREEMENT

This Agreement is made as of the __ day of March, 2006 between COLUMBIA FUNDS SERIES TRUST I (the "Trust"), on behalf of its COLUMBIA INCOME FUND and COLUMBIA INTERMEDIATE BOND FUND series (the "Funds") and COLUMBIA MANAGEMENT ADVISORS, LLC (the "Adviser"). The Trust is registered as an open-end investment company pursuant to the Investment Company Act of 1940 (the "Act"). The Adviser is registered as an investment adviser pursuant to the Investment Advisers Act of 1940. This Agreement relates to the services to be performed by the Adviser with respect to the Funds.

The parties agree as follows:

1. Investment Management Services. The Adviser shall manage the investment operations of the Trust and each Fund, subject to the terms of this Agreement and to the supervision and control of the Trust's Board of Trustees ("Trustees"). The Adviser agrees to perform, or arrange for the performance of, the following services with respect to each Fund:

(a) to obtain and evaluate such information relating to economies, industries, businesses, securities and commodities markets, and individual securities, commodities and indices as it may deem necessary or useful in discharging its responsibilities hereunder;

(b) to formulate and maintain a continuing investment program in a manner consistent with and subject to (i) the Trust's agreement and declaration of trust and by-laws; (ii) the Fund's investment objectives, policies, and restrictions as set forth in written documents furnished by the Trust to the Adviser; (iii) all securities, commodities, and tax laws and regulations applicable to the Fund and the Trust; and (iv) any other written limits or directions furnished by the Trustees to the Adviser;

(c) unless otherwise directed by the Trustees, to determine from time to time securities, commodities, interests or other investments to be purchased, sold, retained or lent by the Fund, and to implement those decisions, including the selection of entities with or through which such purchases, sales or loans are to be effected;

(d) to use reasonable efforts to manage the Fund so that it will qualify as a regulated investment company under subchapter M of the Internal Revenue Code of 1986, as amended;

(e) to make recommendations as to the manner in which voting rights, rights to consent to the Trust or Fund action, and any other rights pertaining to the Trust or the Fund shall be exercised;

(f) to make available to the Trust promptly upon request all of the Fund's records and ledgers and any reports or information reasonably requested by the Trust; and

(g) to the extent required by law, to furnish to regulatory authorities any information or reports relating to the services provided pursuant to this Agreement.

Except as otherwise instructed from time to time by the Trustees, with respect to execution of transactions for the Trust on behalf of a Fund, the Adviser shall place, or arrange for the placement of, all orders for purchases, sales, or loans with issuers, brokers, dealers or other counter parties or agents selected by the Adviser. In connection with the selection of all such parties for the placement of all such orders, the Adviser shall attempt to obtain most favorable execution and price, but may nevertheless in its sole discretion as a secondary factor, purchase and sell portfolio securities from and to brokers and dealers who provide the Adviser with statistical, research and other information, analysis, advice, and similar services. In recognition of such services or brokerage services provided by a broker or dealer, the Adviser is hereby authorized to pay such broker or dealer a commission or spread in excess of that which might be charged by another broker or dealer for the same transaction if the Adviser determines in good faith that the commission or spread is reasonable in relation to the value of the services so provided.

The Trust hereby authorizes any entity or person associated with the Adviser that is a member of a national securities exchange to effect any transaction on the exchange for the account of a Fund to the extent permitted by and in accordance with Section 11(a) of the Securities Exchange Act of 1934 and Rule 11a2-2(T) thereunder. The Trust hereby consents to the retention by such entity or person of compensation for such transactions in accordance with Rule 11a-2-2(T)(a)(iv).

The Adviser may, where it deems to be advisable, aggregate orders for its other customers together with any securities of the same type to be sold or purchased for the Trust or one or

1

more Funds in order to obtain best execution or lower brokerage commissions. In such event, the Adviser shall allocate the shares so purchased or sold, as well as the expenses incurred in the transaction, in a manner it considers to be equitable and fair and consistent with its fiduciary obligations to the Trust, the Funds, and the Adviser's other customers. The Adviser shall for all purposes be deemed to be an independent contractor and not an agent of the Trust and shall, unless otherwise expressly provided or authorized, have no authority to act for or represent the Trust in any way.

2. Administrative Services. The Adviser shall supervise the business and affairs of the Trust and each Fund and shall provide such services and facilities as may be required for effective administration of the Trust and Funds as are not provided by employees or other agents engaged by the Trust; provided that the Adviser shall not have any obligation to provide under this Agreement any such services which are the subject of a separate agreement or arrangement between the Trust and the Adviser, any affiliate of the Adviser, or any third party administrator ("Administrative Agreements").

3. Use of Affiliated Companies and Subcontractors. In connection with the services to be provided by the Adviser under this Agreement, the Adviser may, to the extent it deems appropriate, and subject to compliance with the requirements of applicable laws and regulations and upon receipt of written approval of the Trustees, make use of (i) its affiliated companies and their directors, trustees, officers, and employees and (ii) subcontractors selected by the Adviser, provided that the Adviser shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided by this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by the Adviser or such parties.

4. Expenses Borne by the Trust. Except to the extent expressly assumed by the Adviser herein or under a separate agreement between the Trust and the Adviser and except to the extent required by law to be paid by the Adviser, the Adviser shall not be obligated to pay any costs or expenses incidental to the organization, operations or business of the Trust. Without limitation, such costs and expenses shall include but not be limited to:

(a) all charges of depositories, custodians and other agencies for the safekeeping and servicing of its cash, securities, and other property;

(b) all charges for equipment or services used for obtaining price quotations or for communication between the Adviser or the Trust and the custodian, transfer agent or any other agent selected by the Trust;

(c) all charges for administrative and accounting services provided to the Trust by the Adviser, or any other provider of such services;

(d) all charges for services of the Trust's independent auditors and for services to the Trust by legal counsel;

(e) all compensation of Trustees, other than those affiliated with the Adviser, all expenses incurred in connection with their services to the Trust, and all expenses of meetings of the Trustees or committees thereof;

(f) all expenses incidental to holding meetings of holders of units of interest in the Trust ("Unitholders"), including printing and of supplying each record-date Unitholder with notice and proxy solicitation material, and all other proxy solicitation expense;

(g) all expenses of printing of annual or more frequent revisions of the Trust's prospectus(es) and of supplying each then-existing Unitholder with a copy of a revised prospectus;

(h) all expenses related to preparing and transmitting certificates representing the Trust shares;

(i) all expenses of bond and insurance coverage required by law or deemed advisable by the Board of Trustees;

(j) all brokers' commissions and other normal charges incident to the purchase, sale, or lending of portfolio securities;

(k) all taxes and governmental fees payable to Federal, state or other governmental agencies, domestic or foreign, including all stamp or other transfer taxes;

(m) all interest on indebtedness, if any, incurred by the Trust or a Fund; and

(n) all fees, dues and other expenses incurred by the Trust in connection with membership of the Trust in any trade association or other investment company organization.

5. Allocation of Expenses Borne by the Trust. Any expenses borne by the Trust that are attributable solely to the organization, operation or business of a Fund shall be paid solely out of Fund assets. Any expense borne by the Trust which is not solely attributable to a Fund, nor solely to any other series of shares of the Trust, shall be apportioned in such manner as the Adviser determines is fair and appropriate, or as otherwise specified by the Board of Trustees.

6. Expenses Borne by the Adviser. The Adviser at its own expense shall furnish all executive and other personnel, office space, and office facilities required to render the investment management and administrative services set forth in this Agreement. The Adviser shall pay all expenses of establishing, maintaining, and servicing the accounts of Unitholders in each Fund. However, the Adviser shall not be required to pay or provide any credit for services provided by the Trust's custodian or other agents without additional cost to the Trust.

In the event that the Adviser pays or assumes any expenses of the Trust or a Fund not required to be paid or assumed by the Adviser under this Agreement, the Adviser shall not be obligated hereby to pay or assume the same or similar expense in the future; provided that nothing contained herein shall be deemed to relieve the Adviser of any obligation to the Trust or a Fund under any separate agreement or arrangement between the parties.

7. Management Fee. For the services rendered, facilities provided, and charges assumed and paid by the Adviser hereunder, the Trust shall pay to the Adviser out of the assets of each Fund fees at the annual rate for such Fund as set forth in Schedule A to this Agreement. For each Fund, the management fee shall accrue on each calendar day, and shall be payable monthly on the first business day of the next succeeding calendar month. The daily fee accrual shall be computed by multiplying the fraction of one divided by the number of days in the calendar year by the applicable annual rate of fee, and multiplying this product by the net assets of the Fund, determined in the manner established by the Board of Trustees, as of the close of business on the last preceding business day on which the Fund's net asset value was determined.

8. Retention of Sub-Adviser. Subject to obtaining the initial and periodic approvals required under Section 15 of the Act, the Adviser may retain one or more sub-advisers at the Adviser's own cost and expense for the purpose of furnishing one or more of the services described in Section 1 hereof with respect to the Trust or one or more Funds. Retention of a sub-adviser shall in no way reduce the responsibilities or obligations of the Adviser under this Agreement, and the Adviser shall be responsible to the Trust and its Funds for all acts or omissions of any sub-adviser in connection with the performance of the Adviser's duties hereunder.

9. Non-Exclusivity. The services of the Adviser to the Trust hereunder are not to be deemed exclusive and the Adviser shall be free to render similar services to others.

11. Amendment. This Agreement may not be amended as to the Trust or any Fund without the affirmative votes (a) of a majority of the Board of Trustees, including a majority of those Trustees who are not "interested persons" of the Trust or of the Adviser, voting in person at a meeting called for the purpose of voting on such approval, and (b) of a "majority of the outstanding shares" of the Trust or, with respect to an amendment affecting an individual Fund, a "majority of the outstanding shares" of that Fund. The terms "interested persons" and "vote of a majority of the outstanding shares" shall be construed in accordance with their respective definitions in the Act and, with respect to the latter term, in accordance with Rule 18f-2 under the Act.

12. Effective Date and Termination. This Agreement shall become effective as to any Fund as of the effective date as first written above.

The Adviser shall prepare and furnish to the Trust as to each Fund statistical data and other information in such form and at such intervals as the Trust may reasonably request.

14. Non-Liability of Trustees and Unitholders.

Exhibit (d)(18)

FORM OF

COLUMBIA GROWTH STOCK FUND
COLUMBIA YOUNG INVESTOR FUND

MANAGEMENT AGREEMENT

This Agreement is made as of the __ day of March, 2006 between COLUMBIA FUNDS SERIES TRUST I (the "Trust"), on behalf of its COLUMBIA GROWTH STOCK FUND and COLUMBIA YOUNG INVESTOR FUND series (the "Funds") and COLUMBIA MANAGEMENT ADVISORS, LLC (the "Adviser"). The Trust is registered as an open-end investment company pursuant to the Investment Company Act of 1940 (the "Act"). The Adviser is registered as an investment adviser pursuant to the Investment Advisers Act of 1940. This Agreement relates to the services to be performed by the Adviser with respect to the Funds.

The parties agree as follows:

1. Investment Management Services. The Adviser shall manage the investment operations of the Trust and each Fund, subject to the terms of this Agreement and to the supervision and control of the Trust's Board of Trustees ("Trustees"). The Adviser agrees to perform, or arrange for the performance of, the following services with respect to each Fund:

(a) to obtain and evaluate such information relating to economies, industries, businesses, securities and commodities markets, and individual securities, commodities and indices as it may deem necessary or useful in discharging its responsibilities hereunder;

(b) to formulate and maintain a continuing investment program in a manner consistent with and subject to (i) the Trust's agreement and declaration of trust and by-laws; (ii) the Fund's investment objectives, policies, and restrictions as set forth in written documents furnished by the Trust to the Adviser; (iii) all securities, commodities, and tax laws and regulations applicable to the Fund and the Trust; and (iv) any other written limits or directions furnished by the Trustees to the Adviser;

(c) unless otherwise directed by the Trustees, to determine from time to time securities, commodities, interests or other investments to be purchased, sold, retained or lent by the Fund, and to implement those decisions, including the selection of entities with or through which such purchases, sales or loans are to be effected;

(d) to use reasonable efforts to manage the Fund so that it will qualify as a regulated investment company under subchapter M of the Internal Revenue Code of 1986, as amended;

(e) to make recommendations as to the manner in which voting rights, rights to consent to Trust or Fund action, and any other rights pertaining to the Trust or the Fund shall be exercised;

(f) to make available to the Trust promptly upon request all of the Fund's records and ledgers and any reports or information reasonably requested by the Trust; and

(g) to the extent required by law, to furnish to regulatory authorities any information or reports relating to the services provided pursuant to this Agreement.

Except as otherwise instructed from time to time by the Trustees, with respect to execution of transactions for the Trust on behalf of a Fund, the Adviser shall place, or arrange for the placement of, all orders for purchases, sales, or loans with issuers, brokers, dealers or other counter parties or agents selected by the Adviser. In connection with the selection of all such parties for the placement of all such orders, the Adviser shall attempt to obtain most favorable execution and price, but may nevertheless in its sole discretion as a secondary factor, purchase and sell portfolio securities from and to brokers and dealers who provide the Adviser with statistical, research and other information, analysis, advice, and similar services. In recognition of such services or brokerage services provided by a broker or dealer, the Adviser is hereby authorized to pay such broker or dealer a commission or spread in excess of that which might be charged by another broker or dealer for the same transaction if the Adviser determines in good faith that the commission or spread is reasonable in relation to the value of the services so provided.

The Trust hereby authorizes any entity or person associated with the Adviser that is a member of a national securities exchange to effect any transaction on the exchange for the account of a


Fund to the extent permitted by and in accordance with Section 11(a) of the Securities Exchange Act of 1934 and Rule 11a2-2(T) thereunder. Trust hereby consents to the retention by such entity or person of compensation for such transactions in accordance with Rule 11a-2-2(T)(a)(iv).

The Adviser may, where it deems to be advisable, aggregate orders for its other customers together with any securities of the same type to be sold or purchased for the Trust or one or more Funds in order to obtain best execution or lower brokerage commissions. In such event, the Adviser shall allocate the shares so purchased or sold, as well as the expenses incurred in the transaction, in a manner it considers to be equitable and fair and consistent with its fiduciary obligations to the Trust, the Funds, and the Adviser's other customers. The Adviser shall for all purposes be deemed to be an independent contractor and not an agent of the Trust and shall, unless otherwise expressly provided or authorized, have no authority to act for or represent the Trust in any way.

2. Administrative Services. The Adviser shall supervise the business and affairs of the Trust and each Fund and shall provide such services and facilities as may be required for effective administration of the Trust and Funds as are not provided by employees or other agents engaged by the Trust; provided that the Adviser shall not have any obligation to provide under this Agreement any such services which are the subject of a separate agreement or arrangement between the Trust and the Adviser, any affiliate of the Adviser, or any third party administrator ("Administrative Agreements").

3. Use of Affiliated Companies and Subcontractors. In connection with the services to be provided by the Adviser under this Agreement, the Adviser may, to the extent it deems appropriate, and subject to compliance with the requirements of applicable laws and regulations and upon receipt of written approval of the Trustees, make use of (i) its affiliated companies and their directors, trustees, officers, and employees and (ii) subcontractors selected by the Adviser, provided that the Adviser shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided by this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by the Adviser or such parties.

4. Expenses Borne by the Trust. Except to the extent expressly assumed by the Adviser herein or under a separate agreement between the Trust and the Adviser and except to the extent required by law to be paid by the Adviser, the Adviser shall not be obligated to pay any costs or expenses incidental to the organization, operations or business of the Trust. Without limitation, such costs and expenses shall include but not be limited to:

(a) all charges of depositories, custodians and other agencies for the safekeeping and servicing of its cash, securities, and other property;

(b) all charges for equipment or services used for obtaining price quotations or for communication between the Adviser or the Trust and the custodian, transfer agent or any other agent selected by the Trust;

(c) all charges for administrative and accounting services provided to the Trust by the Adviser, or any other provider of such services;

(d) all charges for services of the Trust's independent auditors and for services to the Trust by legal counsel;

(e) all compensation of Trustees, other than those affiliated with the Adviser, all expenses incurred in connection with their services to the Trust, and all expenses of meetings of the Trustees or committees thereof;

(f) all expenses incidental to holding meetings of holders of units of interest in the Trust ("Unitholders"), including printing and of supplying each record-date Unitholder with notice and proxy solicitation material, and all other proxy solicitation expense;

(g) all expenses of printing of annual or more frequent revisions of the Trust's prospectus(es) and of supplying each then-existing Unitholder with a copy of a revised prospectus;

(h) all expenses related to preparing and transmitting certificates representing the Trust shares;

(i) all expenses of bond and insurance coverage required by law or deemed advisable by the Board of Trustees;

(j) all brokers' commissions and other normal charges incident to the purchase, sale, or lending of portfolio securities;

(k) all taxes and governmental fees payable to Federal, state or other governmental agencies, domestic or foreign, including all stamp or other transfer taxes;

jurisdictions and of registration and qualification of the Trust under all other laws applicable to the Trust or its business activities;

(m) all interest on indebtedness, if any, incurred by the Trust or a Fund; and

(n) all fees, dues and other expenses incurred by the Trust in connection with membership of the Trust in any trade association or other investment company organization.

5. Allocation of Expenses Borne by the Trust. Any expenses borne by the Trust that are attributable solely to the organization, operation or business of a Fund shall be paid solely out of Fund assets. Any expense borne by the Trust which is not solely attributable to a Fund, nor solely to any other series of shares of the Trust, shall be apportioned in such manner as the Adviser determines is fair and appropriate, or as otherwise specified by the Board of Trustees.

6. Expenses Borne by the Adviser. The Adviser at its own expense shall furnish all executive and other personnel, office space, and office facilities required to render the investment management and administrative services set forth in this Agreement. The Adviser shall pay all expenses of establishing, maintaining, and servicing the accounts of Unitholders in each Fund. However, the Adviser shall not be required to pay or provide any credit for services provided by the Trust's custodian or other agents without additional cost to the Trust. In the event that the Adviser pays or assumes any expenses of the Trust or a Fund not required to be paid or assumed by the Adviser under this Agreement, the Adviser shall not be obligated hereby to pay or assume the same or similar expense in the future; provided that nothing contained herein shall be deemed to relieve the Adviser of any obligation to the Trust or a Fund under any separate agreement or arrangement between the parties.

7. Management Fee. For the services rendered, facilities provided, and charges assumed and paid by the Adviser hereunder, the Trust shall pay to the Adviser out of the assets of each Fund fees at the annual rate for such Fund as set forth in Schedule A to this Agreement. For each Fund, the management fee shall accrue on each calendar day, and shall be payable monthly on the first business day of the next succeeding calendar month. The daily fee accrual shall be computed by multiplying the fraction of one divided by the number of days in the calendar year by the applicable annual rate of fee, and multiplying this product by the net assets of the Fund, determined in the manner established by the Board of Trustees, as of the close of business on the last preceding business day on which the Fund's net asset value was determined.

8. Retention of Sub-Adviser. Subject to obtaining the initial and periodic approvals required under Section 15 of the Act, the Adviser may retain one or more sub-advisers at the Adviser's own cost and expense for the purpose of furnishing one or more of the services described in Section 1 hereof with respect to the Trust or one or more Funds. Retention of a sub-adviser shall in no way reduce the responsibilities or obligations of the Adviser under this Agreement, and the Adviser shall be responsible to the Trust and its Funds for all acts or omissions of any sub-adviser in connection with the performance of the Adviser's duties hereunder.

9. Non-Exclusivity. The services of the Adviser to the Trust hereunder are not to be deemed exclusive and the Adviser shall be free to render similar services to others.

10. Standard of Care. Neither The Adviser, nor any of its directors, officers, stockholders, agents or employees shall be liable to the Trust or its Unitholders for any error of judgment, mistake of law, loss arising out of any investment, or any other act or omission in the performance by the Adviser of its duties under this Agreement, except for loss or liability resulting from willful misfeasance, bad faith or gross negligence on the Adviser's part or from reckless disregard by the Adviser of its obligations and duties under this Agreement.

Exhibit (e)(1)

FORM OF
DISTRIBUTION AGREEMENT
COLUMBIA FUNDS

THIS AGREEMENT is made as of March __, 2006, by and between each Massachusetts business trust (each trust, hereinafter, the "Fund") listed on Schedule I on behalf of each series of each Fund that is organized as a trust listed on Schedule I (each, a "Series" and collectively, the "Series"), and Columbia Management Distributors, Inc., a Massachusetts corporation (the "Distributor"). Absent written notification to the contrary by either the Fund or the Distributor, each new investment portfolio established in the future shall automatically become a "Series" for all purposes hereunder and shares of each new class established in the future shall automatically become "Shares" for all purposes hereunder as if set forth on Schedule I.

WHEREAS, the Fund is registered with the Securities and Exchange Commission (the "SEC") as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act");

WHEREAS, the Fund desires to retain the Distributor as the exclusive distributor of the units of beneficial interest in all classes of shares ("Shares") of the Funds and each Series, if applicable, and the Distributor is willing to render such services; and

WHEREAS, the Distributor is registered as a broker-dealer under the Securities Exchange Act of 1934, as amended (the "1934 Act") and is a member of the National Association of Securities Dealers, Inc. (the "NASD").

NOW THEREFORE, in consideration of the promises and mutual covenants herein contained, it is agreed between the parties hereto as follows:

1. SERVICES AS DISTRIBUTOR.

1.1. The Distributor will act as agent for the distribution of Shares in accordance with any instructions of the Fund's Board of Trustees or Board of Directors, as applicable, and with the Fund's registration statement then in effect under the Securities Act of 1933, as amended (the "1933 Act"), and will transmit promptly any orders properly received by it for the purchase or redemption of Shares to the Fund or its transfer agent, or their designated agents. As used in this Agreement, the term "registration statement" shall mean any registration statement, specifically including, among other items, any then-current prospectus together with any related then-current statement of additional information, filed with the SEC with respect to Shares, and any amendments and supplements thereto which at any time shall have been filed.

1.2. The Distributor agrees to use appropriate efforts to solicit orders for the sale of Shares and will undertake such advertising and promotion, as it believes appropriate in connection with such solicitation. The Distributor agrees to offer and sell Shares at the applicable public offering price or net asset value next determined after an order is received. The Fund understands that the Distributor is and may in the future be the distributor of shares of other investment company

-1-

portfolios including portfolios having investment objectives similar to those of the Funds and each Series, if applicable. The Fund further understands that existing and future investors in the Funds and each Series, if applicable, may invest in shares of such other portfolios. The Fund agrees that the Distributor's duties to such portfolios shall not be deemed in conflict with its duties to the Fund under this paragraph 1.2.

1.3. The Distributor shall, at its own expense, finance such activities as it deems reasonable and which are primarily intended to result in the sale of Shares, including, but not limited to, advertising, compensation of underwriters, dealers and sales personnel, the printing and mailing of prospectuses to other than current shareholders, and the printing and mailing of sales literature.

1.4. The Fund shall be responsible for expenses relating to the execution of any and all documents and the furnishing of any and all information and otherwise taking, or causing to be taken, all actions that may be reasonably necessary in connection with the registration of Shares under the 1933 Act and the Fund under the 1940 Act and the qualification of Shares for sale under the so-called "blue sky" laws in such states as the Fund directs and in such states as the Distributor may recommend to the Fund which the Fund approves, and the Fund shall pay all fees and other expenses incurred in connection with such registration and qualification. The Fund shall be also responsible for the preparation, printing and distribution of prospectuses and statements of additional information to shareholders and the direct expenses of the issue of Shares.

1.5. The Distributor shall be responsible for preparing, reviewing and providing advice on all sales literature (e.g., advertisements, brochures and shareholder communications) with respect to each of the Funds and each Series, if applicable, and shall file with the NASD or the appropriate regulators all such materials as are required to be filed under applicable laws and regulations in compliance with such laws and regulations.

1.6. In connection with all matters relating to this Agreement, the Fund and the Distributor agree to comply with all applicable laws, rules and regulations, including, without limitation, all rules and regulations made or adopted pursuant to the 1933 Act, the 1934 Act, the 1940 Act, the regulations of the NASD and all other applicable federal and state laws, rules and regulations. The Distributor agrees to provide the Fund with such certifications, reports and other information as the Fund may reasonably request from time to time to assist it in complying with, and monitoring for compliance with, such laws, rules and regulations.

1.7. Whenever in their judgment such action is warranted by unusual market, economic or political conditions, or by other circumstances of any kind, the Fund's officers may decline to accept any orders for, or make any sales of, Shares until such time as those officers deem it advisable to accept such orders and to make such sales.

1.8. The Fund shall furnish from time to time, for use in connection with the sale of Shares, such information with respect to the Funds and each Series, if applicable, and Shares as the Distributor may reasonably request and the Fund warrants that such information shall be true and correct. Without limited the foregoing, the Fund shall also furnish the Distributor upon

-2-

request with: (a) audited annual and unaudited semi-annual statements of the Fund's books and accounts with respect to each Fund and each Series, if applicable, and (b) from time to time such additional information regarding the Funds' and each Series, if applicable, financial condition as the Distributor may reasonably request.

1.9. The Fund may from time to time adopt one or more distribution plans pursuant to Rule 12b-1 under the 1940 Act. As compensation for services rendered hereunder, the Distributor shall be entitled to receive from the Fund the payments set forth on Schedule II attached hereto, as the same may be amended from time to time by agreement of the parties. In addition, the Distributor shall be entitled to retain any front-end sales charge imposed upon the sale of Shares (and reallow a portion thereof) as specified in the Fund's registration statement and the Fund shall pay to the Distributor the proceeds from any contingent deferred sales charge imposed on the redemption of Shares as specified in the Fund's registration statement. The Distributor, from time to time, may assign to any third party all or any portion of amounts payable to the Distributor under this Agreement.

1.10. The Distributor shall prepare reports for the Board of Trustees or the Board of Directors, as applicable, of the Fund regarding its activities under this Agreement as from time to time shall be reasonably requested by such Board, including reports regarding the use of Rule 12b-1 payments received by the Distributor, if any.

1.11. The Distributor is authorized to enter into written agreements with banks, broker/dealers and other financial institutions (collectively, "Intermediaries"), based on such form(s) of sales support agreements as may be approved by the Board of Trustees or the Board of Directors, as applicable, from time to time. The Distributor also may enter into such agreements based on such additional forms of agreement as it deems appropriate, provided that the Distributor determines that the Fund's responsibility or liability to any person under, or on account of any acts or statements of any such selling agent under, any such sales support agreement does not exceed its responsibility or liability under the form(s) approved by the Board of Trustees or the Board of Directors, as applicable, and provided further that the Distributor determines that the overall terms of any such sales support agreement are not materially less advantageous to the Fund than the overall terms of the form(s) approved by the Board of Trustees or Board of Directors, as applicable. In entering into and performing such agreements, the Distributor shall act as principal and not as agent for the Fund or any Series. Upon the failure of any Intermediary to pay for any order for the purchase of Shares in accordance with the terms of the Fund's or any Series, if applicable, prospectus, the Fund or any Series, if applicable, shall have the right to cancel the sale of such Shares and thereupon the Distributor shall be responsible for any loss sustained as a result thereof.

2. REPRESENTATIONS; INDEMNIFICATION.

2.1. The Fund represents to the Distributor that all registration statements with respect to Shares and shareholder reports with respect to Funds or any Series, if applicable, filed by the Fund with the SEC, have been prepared in conformity with the requirements of the 1933 Act, the 1934 Act and the 1940 Act, as applicable, and rules and regulations of the SEC thereunder. The Fund further represents and warrants to the Distributor that any registration statement, when such

-3-

registration statement becomes effective, and any shareholder report, when such report is filed, will contain all statements required to be stated therein in conformity with the 1933 Act, the 1934 Act and the 1940 Act, as applicable, and the rules and regulations of the SEC; that all statements of fact contained in any such registration statement or shareholder report will be true and correct when such registration statement becomes effective, or when such shareholder report is filed; and that no registration statement, when such registration statement becomes effective, and no shareholder report, when such shareholder report is filed, will include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading to a purchaser of Shares; provided, however, that the foregoing representations and warranties shall not apply to any untrue statement of material fact or omission made in any registration statement or shareholder report in reliance upon and in conformity with any information furnished to the Fund by the Distributor or any affiliate thereof and used in preparation thereof. The Fund authorizes the Distributor and authorized banks, broker/dealers and other financial institutions to use any prospectus or statement of additional information in the form furnished from time to time in connection with the sale of Shares and represented by the Fund as being the then-current form of prospectus or then-current form of statement of additional information.

2.2. The Fund agrees to indemnify, defend and hold the Distributor, its several officers and directors, and any person who controls the Distributor within the meaning of Section 15 of the 1933 Act free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Distributor, its officers and directors, or any such controlling person, may incur under the 1933 Act or under common law or otherwise, arising out of or based upon (a) any breach by the Fund of any provision of this Agreement, or (b) any untrue statement, or alleged untrue statement, of a material fact contained in any registration statement or shareholder report or arising out of or based upon any omission, or alleged omission, to state a material fact required to be stated in any registration statement or shareholder report or necessary to make any statement in such documents not misleading; provided, however, that the Fund's agreement to indemnify the Distributor, its officers and directors, and any such controlling person shall not be deemed to cover any claims, demands, liabilities or expenses arising out of any untrue statement or alleged untrue statement or omission or alleged omission made in any registration statement or shareholder report or in any financial or other statements in reliance upon and in conformity with any information furnished to the Fund by the Distributor or any affiliate thereof and used in the preparation thereof; and further provided that the Fund's agreement to indemnify the Distributor, its officers and directors, and any such controlling person shall not be deemed to cover any liability to the Fund or its shareholders to which the Distributor, is officers and directors, or any such controlling person would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of the Distributor's, its officer's or director's, or any such controlling person's duties, or by reason of the Distributor's, its officer's or director's, or any such controlling person's reckless disregard of its obligations and duties under this Agreement.

The Fund's agreement to indemnify the Distributor, its officers and directors, and any such controlling person, as aforesaid, is expressly conditioned upon the Fund's being notified of any action brought against the Distributor, its officers or directors, or any such controlling person,

-4-

such notification to be given in writing and to be transmitted by personal delivery, first class mail, overnight courier, facsimile or other electronic means to the address or facsimile number contained in paragraph 9 of this Agreement, or to such other addresses or facsimile numbers as the parties hereto may specify from time to time in writing and such notification to be sent to the Fund within a reasonable period of time after the summons or other first legal process shall have been served. The failure to so notify the Fund of any such action shall not relieve the Fund from any liability hereunder, which the Fund may have to the person against whom, such action is brought by reason of any such untrue or alleged untrue statement, or omission or alleged omission, except to the extent the Fund has been actually prejudiced by such delay. The Fund will be entitled to assume at its own expense the defense of any suit brought to enforce any such claim, demand or liability, but, in such case, such defense shall be conducted by counsel of good standing chosen by the Fund and approved by the Distributor, which approval shall not unreasonably be withheld. In the event the Fund elects to assume the defense of any such suit and retain counsel of good standing approved by the Distributor, the defendant or defendants in such suit shall bear the fees and expenses of any additional counsel retained by any of them; but in case the Fund does not elect to assume the defense of any such suit, or in case the Distributor reasonably does not approve of counsel chosen by the Fund, the Fund will reimburse the distributor, its officers and directors, or the controlling person or persons named as defendant or defendants in such suit, for the fees and expenses of any counsel retained by the Distributor or them.

The Fund's indemnification agreement contained in this paragraph 2.2 and the Fund's representations and warranties in this Agreement shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Distributor, its officers or directors, or any controlling person, and shall survive the delivery of any Shares. This agreement of indemnity will inure exclusively to the Distributor's benefit, to the benefit of its several officers and directors, and their respective estates, and to the benefit of the controlling persons and their successors. The Fund agrees promptly to notify the Distributor of the commencement of any litigation or proceedings against the Fund or any of its officers, Trustees, or Directors in connection with the issue and sale of any Shares.

2.3. The Distributor agrees to indemnify, defend and hold the Fund, its several officers, Trustees and Directors, and any person who controls the Fund within the meaning of Section 15 of the 1933 Act free and harmless from and against any and all claims, demands, liabilities and expenses (including the costs of investigation or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Fund, its officers, Trustees or Directors or any such controlling person, may incur under the 1933 Act or under common law or otherwise, but only to the extent that such liability or expense incurred by the Fund, its officers, Trustees or Directors, or such controlling person resulting from such claims or demands, shall arise out of or be based upon (a) any untrue, or alleged untrue, statement of a material fact contained in information furnished by the Distributor or any affiliate thereof to the Fund or its counsel and used in the Fund's registration statement or shareholder reports, or any omission, or alleged omission, to state a material fact in connection with such information furnished by the Distributor or any affiliate thereof to the Fund or its counsel required to be stated in such information or necessary to make such information not misleading, (b) any untrue statement of a material fact contained in any sales literature prepared by the Distributor, or any omission to

-5-

state a material fact required to be stated therein or necessary to make such sales literature not misleading (except to the extent arising out of information furnished by the Fund to the Distributor for use therein), (c) any willful misfeasance, bad faith or gross negligence in the performance of the Distributor's obligations and duties under the Agreement or by reason of its reckless disregard thereof, or (d) any breach by the Distributor of any provision of this Agreement. The Distributor's agreement to indemnify the Fund, its officers, Trustees and Directors, and any such controlling person, as aforesaid, is expressly conditioned upon the Distributor's being notified of any action brought against the Fund, its officers, Trustees or Directors, or any such controlling person, such notification to be given in writing and to be transmitted by personal delivery, first class mail, overnight courier, facsimile or other electronic means to the address or facsimile number contained in paragraph 9 of this Agreement, or to such other addresses or facsimile numbers as the parties hereto may specify from time to time in writing and such notification to be sent to the Distributor by the person against whom such action is brought, within a reasonable period of time after the summons or other first legal process shall have been served. The failure to so notify the Distributor of any such action shall not relieve the Distributor or any affiliate thereof from any liability hereunder, which the Distributor or any affiliate thereof may have to the Fund, its officers, Trustees or Directors, or to such controlling person by reason of any such untrue or alleged untrue statement, or omission or alleged omission, or other conduct covered by this indemnity agreement, except to the extent the Distributor has been actually prejudiced by such delay. The Distributor shall have the right to control the defense of such action, with counsel of good standing of its own choosing, approved by the Board of Trustees or Board of Directors of the Fund, as applicable, which approval shall not unreasonably be withheld, if such action is based solely upon such misstatement or omission, or alleged misstatement or omission, on the Distributor's part or any affiliate thereof.

2.4. The Fund agrees to advise the Distributor as soon as reasonably practicable of the issuance by the SEC of any stop order suspending the effectiveness of the registration statement then in effect or of the initiation of any proceeding for that purpose. Thereafter, no Shares shall be offered by either the Distributor or the Fund under any of the provisions of this Agreement and no orders for the purchase or sale of Shares hereunder shall be accepted by the Fund if and so long as the effectiveness of the registration statement then in effect or any necessary amendments thereto shall be suspended under any of the provisions of the 1933 Act, or if and so long as a current prospectus, as required by Section 10(b) of the 1933 Act is not on file with the SEC; provided, however, that nothing contained in this paragraph 2.4 shall in any way restrict or have any application to or bearing upon the Fund's obligation to repurchase Shares from any shareholder in accordance with the provisions of the Fund's prospectus or Declaration of Trust.

3. CONFIDENTIALITY.

The Fund and Distributor may receive from each other information, or access to information, about the customers or about consumers generally (collectively, "Customer Information") including, but not limited to, nonpublic personal information such as a customer's name, address, telephone number, account relationships, account balances and account histories. Each of the Fund and Distributor agrees on behalf of their respective employees that all information, including Customer Information, obtained pursuant to this Agreement shall be considered confidential information. Except as permitted by law or required by order of a court

-6-

or governmental authority, or required by any self-regulatory organization, having jurisdiction over the parties, none of the parties shall disclose such confidential information to any other person or entity or use such confidential information other than to carry out the purposes of this Agreement, including its use under applicable provisions of the SEC's Regulation S-P in the ordinary course of carrying out the purposes of this Agreement.

4. ANTI-MONEY LAUNDERING PROGRAM.

The Distributor represents and warrants that it (a) has adopted an anti-money laundering compliance program ("AML Program") that satisfies the requirements of all applicable laws and regulations; and (b) will notify the Fund promptly if an inspection by the appropriate regulatory authorities of its AML Program identifies any material deficiency, and will promptly remedy any material deficiency of which it learns.

5. LIMITATIONS OF LIABILITY.

Except as provided in paragraph 2.3, the Distributor shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund or any Series in connection with matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard of its obligations and duties under this Agreement.

6. TERM.

6.1. This Agreement shall become effective on the date of its execution and, unless sooner terminated as provided herein, shall continue in effect for a period of two (2) years from the date written above. This Agreement shall thereafter continue from year to year, provided such continuance is specifically approved at least annually by (i) the Fund's Board of Trustees or Board of Directors, as applicable, or (ii) a vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the Fund or any Series, if applicable, provided that in either event the continuance is also approved by the majority of the Fund's Trustees or Directors, as applicable, who are not parties to this Agreement or interested persons (as defined in the 1940 Act) of any such party, by vote cast in person at a meeting called for the purpose of voting on such approval.

Ladies and Gentlemen:

We wish to enter into this Shareholder Servicing Plan Implementation Agreement ("Agreement") with you concerning the provision of services as set forth herein. The terms and conditions of this Agreement are as follows:

1. Provision of Services

(a) You will from time to time enter into agreements with banks, broker/dealers and other financial institutions (collectively "Intermediaries") pursuant to which the Intermediaries will agree to provide personal services to, and maintain accounts of, their clients ("Customers") who may from time to time beneficially own shares of one or more of the portfolios (collectively, the "Funds") of the undersigned trust(s) that have a Board approved shareholder servicing plan. The shares of the Funds are collectively referred to herein as "Shares."

(b) You will provide such office space and equipment, facilities and personnel (which may be any part of the space, equipment and facilities currently used in your business, or any personnel employed by you) as may be reasonably necessary or beneficial in order to provide the services contemplated hereby.

(c) You will pay to the Intermediaries, out of the Service Fee (as defined below), such amounts as may be agreed between you and the Intermediaries in return for the provision by the Intermediaries of personal services and/or the maintenance of shareholder accounts as described in Section 1(a).

(d) For all purposes of this Agreement you will be deemed to be an independent contractor, and will have no authority to act as agent for us in any other capacity, except as expressly provided herein.

2. Compensation

(a) In consideration of the services provided by you hereunder, we will pay to you a fee as set forth in Schedule II (the "Servicing Fee"). The Servicing Fee may be prospectively increased or decreased by us, in our sole discretion, at any time upon notice to you.

(b) Compensation payable under this Agreement is subject to, among other things, the National Association of Securities Dealers, Inc. ("NASD") Conduct Rules governing receipt by NASD members of service fees from registered investment companies (the "NASD Service Fee Rule"). Such compensation shall only be paid if permissible under the NASD Service Fee Rule and shall not be payable for services that are deemed to be distribution-related services, or to the extent otherwise prohibited by the NASD Service Fee Rule.

3. Reports

You agree to furnish us with such information as we may reasonably request, and will otherwise cooperate with us and our designees (including, without limitation, any auditors or legal counsel designated by us) in connection with the preparation of reports to our Board of Trustees concerning this Agreement and the monies paid or payable by us pursuant hereto, as well as any other reports or filings that may be required by law. You agree to provide us with such certifications, reports and other information as we may reasonably request from time to time to assist us in complying with, and monitoring for compliance with, such laws, rules and regulations.

4. Term

(a) This Agreement shall become effective on the date of its execution and, unless sooner terminated as provided herein, shall continue in effect from year to year with respect to a Fund, provided such continuance is specifically approved at least annually by (i) our Board of Trustees, or (ii) a vote of a majority (as defined in the Investment Company Act of 1940, as amended ("1940 Act")) of the outstanding voting securities of the Fund, provided that in either event the continuance is also approved by the majority of our Trustees who are not parties to this Agreement or interested persons (as defined in the 1940 Act) of any such party, by vote cast in person at a meeting called for the purpose of voting on such approval.

(b) This Agreement is terminable with respect to a Fund, without penalty, on not less than sixty (60) days' written notice, by our Board of Trustees, by vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of such Fund, or by you. This Agreement will also terminate automatically in the event of its assignment (as defined in the 1940 Act). Upon termination, the obligations of the parties under this Agreement shall cease except for unfulfilled obligations and liabilities arising prior to termination.

(i) its affiliated companies and their directors, trustees, officers and employees and (ii) subcontractors selected by it, provided that it shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided in this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by CMA or such parties.

4. Expenses Borne By Trust. Except to the extent expressly assumed by CMA herein or under a separate agreement between a Trust and CMA and except to the extent required by law to be paid by CMA, each Trust shall pay all costs and expenses incidental to its organization, operations and business. Without limitation, such costs and expenses shall include but not be limited to:

(b) All charges for equipment or services used for obtaining price quotations or for communication between CMA or the Trust and the custodian, transfer agent or any other agent selected by the Trust;

5. Allocation Of Expenses Borne By Trust. Any expenses borne by a Trust that are attributable solely to the organization, operation or business of a constituent Fund shall be paid solely out of such Fund's assets. Any expense borne by a Trust which is not solely attributable to a constituent Fund, nor solely to any other series of shares of the Trust, shall be apportioned in such manner as CMA determines is fair and appropriate, or as otherwise specified by the Trustees.

6. Expenses Borne By CMA. CMA at its own expense shall furnish all executive and other personnel, office space, and office facilities required to render the services set forth in this Agreement. However, CMA shall not be required to pay or provide any credit for services provided by the Trust's custodian or other agents without additional cost to the Trust.

In the event that CMA pays or assumes any expenses of a Trust or a Fund not required to be paid or assumed by CMA under this Agreement, CMA shall not be obligated hereby to pay or assume the same or similar expense in the future; provided that nothing contained herein shall be deemed to relieve CMA of any obligation to a Trust or a Fund under any separate agreement or arrangement between the parties.

7. Administration Fee. Each Trust shall pay to CMA, or to such person(s) as CMA may from time to time instruct, for services rendered and costs incurred in connection with the performance of duties hereunder, such compensation and reimbursement as may from time to time be agreed to by the Trust and CMA.

8. Non-Exclusivity. The services of CMA to the Trusts and Funds hereunder are not to be deemed exclusive and CMA shall be free to render similar services to others.

9. Standard Of Care. Neither CMA, nor any of its directors, officers or stockholders, agents or employees shall be liable to any Trust, Fund, or its shareholders for any action taken or thing done by it or its subcontractors or agents on behalf of the Trust or Fund in carrying out the terms and provisions of this Agreement if done in good faith and without gross negligence, willful misfeasance or reckless disregard of duties and obligations hereunder on the part of CMA, its subcontractors, or agents.

10. Effective Date, Amendment, And Termination. This Agreement shall become effective as to each Fund as of the effective date for Fund specified in Schedule A hereto and, unless terminated as hereinafter provided, shall remain in effect with respect to the Fund thereafter from year to year so long as such continuance is specifically approved with respect to the Fund at least annually by a majority of the Trustees who are not interested persons of the relevant Trust or CMA.

As to any Trust or Fund, this Agreement may be modified or amended from time to time by mutual agreement between CMA and the Trust and may be terminated by CMA or the Trust by at least sixty (60) days' written notice given by the terminating party to the other party. Upon termination as to a Fund, the relevant Trust shall pay to CMA such compensation as may be due under this Agreement as of the date of such termination and shall reimburse CMA for its costs, expenses, and disbursements payable under this Agreement to such date. In the event that, in connection with a termination, a successor to any of the duties or responsibilities of CMA

-3-

hereunder is designated by the Trust by written notice to CMA, upon such termination CMA shall promptly, and at the expense of the Trust or Fund with respect to which this Agreement is terminated, transfer to such successor all relevant books, records, and data established or maintained by CMA under this Agreement and shall cooperate in the transfer of such duties and responsibilities, including provision, at the expense of the Fund, for assistance from CMA personnel in the establishment of books, records, and other data by such successor.

11. Assignment. Any interest of CMA under this Agreement with respect to any Trust shall not be assigned either voluntarily or involuntarily, by operation of law or otherwise, without the prior written consent of the Trust.

12. Books And Records. CMA shall maintain, or oversee the maintenance by such other persons as may from time to time be approved by the Trustees to maintain, the books, documents, records and data required to be kept by each Trust under the 1940 Act, the laws of the Commonwealth of Massachusetts or such other authorities having jurisdiction over the Trust or Fund or as may otherwise be required for the proper operation of the business and affairs of the Trust or Fund (other than those required to be maintained by any investment adviser retained by the Trust on behalf of Fund in accordance with Section 15 of the 1940 Act).

CMA will periodically send to each Trust all books, documents, records, and data of the Trust and Funds that are no longer needed for current purposes or required to be retained as set forth herein. CMA shall have no liability for loss or destruction of said books, documents, records, or data after they are returned to the appropriate Trust.

CMA agrees that all such books, documents, records, and data which it maintains shall be maintained in accordance with Rule 31a-3 of the 1940 Act and that any such items maintained by it shall be the property of the relevant Trust. CMA further agrees to surrender promptly to a Trust any such items it maintains upon request, provided that CMA shall be permitted to retain a copy of all such items. CMA agrees to preserve all such items maintained under Rule 31a-1 for the period prescribed under Rule 31a-2 of the 1940 Act.

Each Trust shall furnish or otherwise make available to CMA such copies of the financial statements, proxy statements, reports, and other information relating to the business and affairs of its Funds as CMA may, at any time or from time to time, reasonably require in order to discharge its obligations under this Agreement.

13. Confidentiality. CMA agrees on behalf of itself and its employees to treat confidentially and as proprietary information of each Trust all records and other information relative to the Trust and its prior, present or potential shareholders and not to use such records and information for any purpose other than performance of its responsibilities and duties under this Agreement, except after prior notification to and approval in writing by the Trust, which approval shall not be unreasonably withheld and may not be withheld where CMA may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities or when so requested by the Trust.

14. Compliance. CMA agree to comply with all applicable federal, state and local laws and regulations, codes, orders and government rules in the performance of its duties under this

-4-

Agreement. CMA agree to provide each Trust with such certifications, reports and other information as the Trust may reasonably request from time to time to assist it in complying with, and monitoring for compliance with, applicable laws, rules and regulations.

15. Miscellaneous. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts.

The captions in this Agreement are included for convenience of reference only and in no way define or limit any of the provisions of this Agreement or otherwise affect their construction or effect. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

A copy of the Agreement and Declaration of Trust of the Trusts that are organized as Massachusetts business trusts, as amended or restated from time to time, is on file with the Secretary of the Commonwealth of Massachusetts, and notice is hereby given that this Agreement is executed on behalf of each of these Trusts by an officer or Trustee of the Trust in his or her capacity as an officer or Trustee of the Trust and not individually and that the obligations of or arising out of this Agreement are not binding upon any of the Trustees, officers or shareholders individually but are binding only upon the assets and property of the Trust. Furthermore, notice is given that the assets and liabilities of each series of each Trust is separate and distinct and that the obligations of or arising out of this Agreement with respect to the series of each Trust are several and not joint, and to the extent not otherwise reasonably allocated among such series by the Trustees of the Trust, shall be deemed to have been allocated in accordance with the relative net assets of such series, and CMA agrees not to proceed against any series for the obligations of another series.

1. Appointment. Each Trust appoints CMA as its agent to perform the pricing and bookkeeping services described below for each Fund.

2. Pricing and Bookkeeping Services. Subject to the terms of this Agreement and the supervision and control of the relevant Trust's Board of Trustees (the "Trustees"), CMA agrees to provide the services indicated for each Fund on Schedule B hereto.

3. Audit, Use and Inspection. CMA shall make available on its premises during regular business hours all records of a Fund for reasonable audit, use and inspection by the Funds, its agents and any regulatory agency having authority over the Fund.

4. Compensation. For the services provided pursuant to this Agreement, the Trust on behalf of each Fund will pay to CMA, or to such person(s) as CMA may from time to time instruct, the fee set forth on Schedule C hereto.

5. Compliance. CMA shall comply with applicable provisions relating to pricing and bookkeeping as set forth in the prospectuses and statements of additional information of each Fund, applicable resolutions of the Board of Trustees of the Trust and applicable laws and rules in the provision of services under this Agreement.

6. Limitation of Liability. In the absence of willful misfeasance, bad faith or gross negligence on the part of CMA, or reckless disregard of its obligations and duties hereunder, CMA shall not be subject to any liability to any Trust or Fund, to any shareholder of any Trust or Fund or to any other person, firm or organization, for any act

-1-

or omission in the course of, or connected with, rendering services hereunder. The provisions of this Paragraph 6 shall survive any termination of this Agreement.

7. Amendments. Each Trust shall submit to CMA a reasonable time in advance of filing with the Securities and Exchange Commission copies of any changes in its Registration Statements. If a change in documents or procedures materially increases the cost to CMA of performing its obligations, CMA shall be entitled to receive such reasonable additional compensation as shall be agreed to in writing by the parties.

8. Duration and Termination. This Agreement may be changed only by a writing executed by each party. This Agreement: (a) shall continue in effect from year to year so long as approved annually by vote of a majority of the Trustees, including a majority of the Trustees who are not affiliated with CMA;
(b) may be terminated at any time without penalty by sixty days' written notice to either party; and (c) may be terminated at any time for cause by either party if such cause remains unremedied for a reasonable period not to exceed ninety days after receipt of written specification of such cause. If a Trust designates a successor to any of CMA's obligations other than as a result of the termination of this Agreement pursuant to Paragraph 8(c), CMA shall, at the expense and direction of the Trust, transfer to the successor all relevant Fund records maintained by CMA.

9. Use of Affiliated Companies and Subcontractors. In connection with the services to be provided by CMA under this Agreement, CMA may, to the extent it deems appropriate, and subject to compliance with the requirements of applicable laws and regulations and upon receipt of approval of the Trustees, make use of
(i) its affiliated companies and their directors, trustees, officers and employees and (ii) subcontractors selected by it, provided that it shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided in this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by CMA or such parties, except to the extent specifically provided otherwise in this Agreement.

10. Confidentiality. CMA agrees on behalf of itself and its employees to treat confidentially and as proprietary information of each Trust all records and other information relative to the Trust and its prior, present or potential shareholders and not to use such records and information for any purpose other than performance of its responsibilities and duties under this Agreement, except after prior notification to and approval in writing by the Trust, which approval shall not be unreasonably withheld and may not be withheld where CMA may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities or when so requested by the Trust.

11. Sarbanes-Oxley Act. CMA agrees that any information that CMA provides that is necessary to complete a report or other filing that is required to be certified by certain of a Trust's officers pursuant to the Sarbanes-Oxley Act of 2002 ("Sarbox") and regulations issued and in effect from time to time under Sarbox will be true and complete when given. CMA further agrees that any written representation or

-2-

certification it provides to a Trust and/or the officers of the Trust in support of a certification by them to the Securities and Exchange Commission pursuant to Sarbox and/or any rules or regulations issued from time to time under Sarbox will be true and complete when given. The provisions of this Paragraph 11 shall survive any termination of this Agreement.

12. Compliance. CMA agree to comply with all applicable federal, state and local laws and regulations, codes, orders and government rules in the performance of its duties under this Agreement. CMA agree to provide each Trust with such certifications, reports and other information as the Trust may reasonably request from time to time to assist it in complying with, and monitoring for compliance with, applicable laws, rules and regulations.

13. Miscellaneous. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts.

The captions in this Agreement are included for convenience of reference only and in no way define or limit any of the provisions of this Agreement or otherwise affect their construction or effect. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

A copy of the Agreement and Declaration of Trust of the Trusts that are organized as Massachusetts business trusts, as amended or restated from time to time, is on file with the Secretary of the Commonwealth of Massachusetts, and notice is hereby given that this Agreement is executed on behalf of each of these Trusts by an officer or Trustee of the Trust in his or her capacity as an officer or Trustee of the Trust and not individually and that the obligations of or arising out of this Agreement are not binding upon any of the Trustees, officers or shareholders individually but are binding only upon the assets and property of the Trust. Furthermore, notice is given that the assets and liabilities of each series of each Trust is separate and distinct and that the obligations of or arising out of this Agreement with respect to the series of each Trust are several and not joint, and to the extent not otherwise reasonably allocated among such series by the Trustees of the Trust, shall be deemed to have been allocated in accordance with the relative net assets of such series, and CMA agrees not to proceed against any series for the obligations of another series.

[LIBERTY VARIABLE INVESTMENT TRUST]

[COLUMBIA FUNDS SERIES TRUST I, STEINROE VARIABLE INVESTMENT TRUST]

For each Fund of each Trust, CMA will value all securities and other assets of the Fund, and compute the net asset value per share of such Fund, at such times and dates and in the manner and by such methodology as is specified in the then currently effective prospectus and statement of additional information for such Fund, and pursuant to such other written procedures or instructions furnished to CMA by the Trust. To the extent procedures or instructions used to value securities or other assets of a Fund under this Agreement are at any time inconsistent with any applicable law or regulation, the Trust will provide CMA with written instructions for valuing such securities or assets in a manner which the Trust represents to be consistent with applicable law and regulation.

CMA will calculate with such frequency as each Trust directs, the net income of each Fund for dividend purposes and on a per share basis. Such calculation will be at such times and dates and in such manner as the Trust instructs CMA in writing. For purposes of such calculation, CMA is not responsible for determining whether any dividend or interest accruable to the Trust is or will be actually paid, but will accrue such dividend and interest unless otherwise instructed by the Trust.

CMA will calculate gains or losses of each Fund from the sale or other disposition of assets of that Fund as the Trust directs.

At the request of a Trust, CMA will compute yields for each Fund of the Trust for such periods and using such formula as the Trust instructs.

CMA will provide each Trust, the Trust's transfer agent and such other parties as directed by the Trust with the net asset value per share, the net income per share and yields for each Fund of the Trust at such time and in such manner and format and with such frequency as the parties mutually agree.

Each Trust will furnish CMA with any and all instructions, explanations, information, specifications and documentation deemed necessary by CMA in the performance of its duties hereunder, including, without limitation, the amounts and/or written formula for calculating the amounts, and times of accrual of liabilities and expenses of each Fund. Each Trust will also at


any time and from time to time furnish CMA with bid, offer and/or market values of securities owned by the Trust if the same are not available to CMA from a pricing or similar service designated by the Trust for use by CMA to value securities or other assets. CMA is at no time required to commence or maintain any utilization of, or subscriptions to, any such service which will be the sole responsibility and expense of the Trust.

CMA will, as agent for each Trust, maintain and keep current and preserve the general ledger and other accounts, books, and financial records of the Trust relating to activities and obligations under this Agreement in accordance with the applicable provisions of Sections 31(a) of the General Rules and Regulations under the Investment Company Act of 1940, as amended (the "Rules").

All records maintained and preserved by CMA pursuant to this Agreement which each Trust is required to maintain and preserve in accordance with the Rules will be and remain the property of the Trust and will be surrendered to the Trust promptly upon request in the form in which such records have been maintained and preserved.

CMA will make available on its premises during regular business hours all records of a Trust for reasonable audit, use and inspection by the Trust, its agents and any regulatory agency having authority over the Trust.

Exhibit (h)(3)

FORM OF

TRANSFER, DIVIDEND DISBURSING AND
SHAREHOLDERS' SERVICING AGENT AGREEMENT

This agreement (the "Agreement") is made as of March __, 2006, by and between the Massachusetts business trusts acting on behalf of their series all as listed on Schedule A hereto (as the same may from time to time be amended to add or delete one or more series of such trusts) (each such trust and corporation being hereinafter referred to as a "Trust" and each series of a Trust, if any, being hereinafter referred to as a "Fund" with respect to that Trust, but for any Trust that does not have any separate series, then any reference to the "Fund" is a reference to that Trust), Columbia Management Services, Inc., a Massachusetts corporation ("CMS"), and Columbia Management Advisors, LLC ("CMA"), a Delaware limited liability company.

WHEREAS, each Trust is a registered investment company and desires that CMS perform certain services for the Funds; and

WHEREAS, CMS is willing to perform such services upon the terms and subject to the conditions set forth herein.

NOW THEREFORE, in consideration of the mutual promises and covenants set forth herein, the parties hereto agree as follows:

1. Appointment. Each Trust hereby appoints CMS to act as Transfer Agent, Dividend Disbursing Agent and Shareholders' Servicing Agent for the Funds and as agent for the Funds' shareholders in connection with the shareholder plans described in the Prospectus (as defined below), and CMS accepts such appointments and will perform the respective duties and functions of such offices in the manner hereinafter set forth.

Notwithstanding such appointments, however, the parties hereto agree that CMA may, upon thirty (30) days prior written notice to the Trust, assume such duties and functions itself. In such event, CMA shall have all of the rights and obligations of CMS hereunder. However, whether or not CMA assumes such duties and functions, CMA guarantees the performance of CMS hereunder and shall be responsible financially and otherwise to the Trust for the performance by CMS of its obligations under this Agreement.

2. Compensation. Each Trust shall pay to CMS, or to such person(s) as CMS may from time to time instruct, for services rendered and costs incurred in connection with the performance of duties hereunder, such compensation and reimbursement as may from time to time be approved by vote of the Trustees of the Trust.

Schedule B hereto sets forth the compensation and reimbursement arrangements to be effective as of the date of this Agreement, and the treatment of all interest earned with respect to balances in the accounts maintained by CMS referred to in Sections 6, 10 and 11 of this Agreement, net of any charges imposed by the bank(s) at which CMS maintains such accounts.

3. Copies of Documents. Each Trust will furnish CMS with copies of the following documents: the Declaration of Trust of the Trust and all amendments thereto; and the Trust's


Registration Statement as in effect on the date hereof under the Securities Act of 1933, as amended, and the Investment Company Act of 1940, as amended, and all amendments or supplements thereto hereafter filed. The Prospectus(es) and Statement(s) of Additional Information contained in such Registration Statement, as from time to time amended and supplemented, together are herein collectively referred to as the "Prospectus."

4. Share Certificates. If the Trustees of a Trust shall have resolved that all of the Trust's (or a particular Fund's) shares of beneficial interest, or all of the shares of a particular series or class of such shares, shall be issued in certificated form, CMS shall maintain a sufficient supply of blank share certificates representing such shares, in the form approved from time to time by the Trustees of the Trust. Such blank share certificates shall be properly signed, manually or by facsimile signature, by the duly authorized officers of the Trust, and shall bear the seal or facsimile thereof of the Trust; and notwithstanding the death, resignation or removal of any officer of the Trust authorized to sign such share certificates, CMS may continue to countersign certificates which bear the manual or facsimile signature of such officer until otherwise directed by the Trust.

5. Lost or Destroyed Certificates. In case of the alleged loss or destruction of any shareholder certificate, no new certificate shall be issued in lieu thereof, unless there shall first be furnished to CMS an affidavit of loss or non-receipt by the holder of shares with respect to which a certificate has been lost or destroyed, supported by an appropriate bond satisfactory to CMS and the Trust issued by a surety company satisfactory to CMS.

6. Receipt of Funds for Investment. CMS will maintain one or more accounts with its cash management bank into which it will deposit funds payable to CMS as agent for, or otherwise identified as being for the account of, the Funds or the Distributor, prior to crediting such funds to the respective accounts of the Funds and the Distributor. Thereafter, CMS will determine the amount of any such funds due a Fund (equal to the number of Fund shares sold by the Fund computed pursuant to paragraph 7 hereof, multiplied by the net asset value of a Fund share next determined after receipt of such purchase order) and the Distributor (equal to the sales charge applicable to such sale computed pursuant to paragraph 9 hereof), respectively, deposit the portion due the Distributor in its account as may from time to time be designated by the Distributor, deposit the net amount due the Fund in the Fund's account with its custodian (the "Custodian"), notify the Distributor (such notification to the Distributor to include the amount of such sales charge to be remitted by the Distributor to the dealer participating in the sale, computed pursuant to paragraph 9 hereof) and the Fund, respectively, of such deposits, such notification to be given as soon as practicable on the next business day stating the total amount deposited to said accounts during the previous business day. Such notification shall be confirmed in writing.

7. Shareholder Accounts. Upon receipt of any funds referred to in paragraph 6 hereof, CMS will compute the number of shares purchased by the shareholder according to the net asset value of Fund shares next determined after such receipt less the applicable sales charge, calculated pursuant to paragraph 9 hereof; and

(a) in the case of a new shareholder, open and maintain an open account for such shareholder in the name or names set forth in the subscription application form;

-2-

(b) if the Trustees of a Trust have resolved that all of the Trust's shares of beneficial interest, or all of the shares of a particular series or class, shall be issued in certificated form, and if specifically requested in writing by the shareholder, countersign, issue and mail, by first class mail, to the shareholder at his or her address set forth in the shareholder records of the Trust maintained by CMS a share certificate for full shares purchased.

(c) send to the shareholder a confirmation indicating the amount of full and fractional shares purchased (in the case of fractional shares, rounded to three decimal places) and the price per share; and

(d) in the case of a request to establish an accumulation plan, withdrawal plan, group plan or other plan or program being offered by the Fund's Prospectus, open and maintain such plan or program for the shareholder in accordance with the terms thereof;

all subject to any reasonable instructions which the Distributor or each Trust may give to CMS with respect to rejection of orders for shares.

8. Unpaid Checks. In the event that any check or other order for payment of money on the account of any shareholder or new investor is returned for any reason, CMS will take such steps, including imposition of a reasonable processing or handling fee on such shareholder or investor, as CMS may, in CMS's discretion, deem appropriate, or as each Trust or the Distributor may instruct CMS.

9. Sales Charge. In computing the number of shares to credit to the account of a shareholder pursuant to paragraph 7 hereof, CMS will calculate the total of the applicable Distributor and representative sales charges, commission or other amount, if any, with respect to each purchase as set forth in the Prospectus and in accordance with any notification filed with respect to combined and accumulated purchases. CMS will also determine the portion of each sales charge, commission or other amount, if any, payable by the Distributor to the dealer or other amount, payable by the Distributor to the dealer participating in the sale in accordance with such schedules as are from time to time delivered by the Distributor to CMS.

10. Dividends and Distributions. Each Trust will promptly notify CMS of the declaration of any dividends or distribution with respect to Fund shares, the amount of such dividend or distribution, the date each such dividend or distribution shall be paid, and the record date for determination of shareholders entitled to receive such dividend or distribution. As Dividend Disbursing Agent, CMS will, on or before the payment date of any such dividend or distribution, notify the Custodian of the estimated amount of cash required to pay such dividend or distribution, and each Trust agrees that on or before the mailing date of such dividend or distribution it will instruct the Custodian to make available to CMS sufficient funds therefor in the dividend and distribution account maintained by CMS with the Custodian. As Dividend Disbursing Agent, CMS will prepare and distribute to shareholders any funds to which they are entitled by reason of any dividend or distribution and, in the case of shareholders entitled to receive additional shares by reason of any such dividend or distribution, CMS will make appropriate credits to their accounts and prepare and mail to shareholders a confirmation statement and, if required, a certificate in respect of such additional shares.

11. Repurchase and Redemptions. CMS will receive and stamp with the date of receipt all certificates and requests delivered to CMS for repurchase or redemption of shares and CMS will process such repurchases as agent for the Distributor and such redemptions as agent for each Trust as follows:

(a) If such certificate or request complies with standards for repurchase or redemption approved from time to time by the Trust, CMS will, on or prior to the seventh calendar day succeeding the receipt of any such request for repurchase or redemption in good order, deposit any contingent deferred sales charge ("CDSC") due the Distributor in its account with such bank as may from time to time be designated by the Distributor and pay to the shareholder from funds deposited by the Trust from time to time in the repurchase and redemption account maintained by CMS with its cash management bank, the appropriate repurchase or redemption price, as the case may be, as set forth in the Prospectus;

(b) If such certificate or request does not comply with said standards for repurchase or redemption as approved by the Trust, CMS will promptly notify the shareholder of such fact, together with the reason therefor, and shall effect such repurchase or redemption at the price in effect at the time of receipt of documents complying with said standards, or, in the case of a repurchase, at such other time as the Distributor, as agent for the Trust, shall so direct; and

(c) CMS shall notify the Trust and the Distributor as soon as practicable on each business day of the total number of Fund shares covered by requests for repurchase or redemption which were received by CMS in proper form on the previous business day, and shall notify the Distributor of deposits to its account with respect to any CDSC, such notification to be confirmed in writing.

12. Exchanges and Transfers. Upon receipt by CMS of a request to exchange Fund shares held in a shareholder's account for shares of another Fund, CMS will verify that the exchange request is made by authorized means and will process a redemption and corresponding purchase of shares in accordance with each Trust's redemption and purchase policies and in accordance with the redemption and purchase provisions of this Agreement. Upon receipt by CMS of a request to transfer Fund shares, and receipt of a share certificate for transfer or an order for the transfer of uncertificated shares, in either case with such endorsements, instruments of assignment or evidence of succession as CMS may require and accompanied by payment of any applicable transfer taxes, and satisfaction of any conditions contained in the Trust's Declaration of Trust, By-Laws, and Prospectus, CMS will record the transfer of ownership of such shares in the appropriate records and will process the transfer in accordance with the Trust's transfer policies and will open an account for the transferee, if a new shareholder, in accordance with the provisions of this Agreement.

13. Systematic Withdrawal Plans. CMS will administer systematic withdrawal plans pursuant to the provisions of withdrawal orders duly executed by shareholders and the relevant Fund's Prospectus. Payments upon such withdrawal orders shall be made by CMS from the appropriate account maintained by the Trust with the Custodian. Prior to the payment date CMS will withdraw from a shareholder's account and present for repurchase or redemption as many shares as shall be sufficient to make such withdrawal payment pursuant to the provisions of the shareholder's withdrawal plan and the relevant Fund's Prospectus.

-4-

14. Letters of Intent and Other Plans. CMS will process such letters of intent for investing in Fund shares as are provided for in the Prospectus, and CMS will act as escrow agent pursuant to the terms of such letters of intent duly executed by shareholders. CMS will make appropriate deposits to the account of the Distributor for the adjustment of sales charges as therein provided and will currently report the same to the Distributor, it being understood, however, that computations of any adjustment of sales charge shall be the responsibility of the Distributor or the Trust. CMS will process such accumulation plans, group programs and other plans or programs for investing in shares as are provided for in the Prospectus. In connection with any such plan or program, and with withdrawal plans described in paragraph 12 hereof, CMS will act as plan agent for shareholders and in so acting shall not be the agent of the Trust.

15. Tax Returns and Reports. CMS will prepare, file with the Internal Revenue Service and any other federal, state or local governmental agency which may require such filing, and, if required, mail to shareholders such returns for reporting dividends and distributions paid by the Funds as are required to be so prepared, filed and mailed by applicable laws, rules and regulations, and CMS will withhold such sums as are required to be withheld under applicable Federal and state income tax laws, rules and regulations.

16. Record Keeping. CMS will maintain records, which at all times will be the property of the respective Trust and available for inspection by the Trust and Distributor, showing for each shareholder's account the following:

(a) Name, address and United States taxpayer identification or Social Security number, if provided (or amounts withheld with respect to dividends and distributions on shares if a taxpayer identification or Social Security number if not provided);

(b) Number of shares held and number of shares for which certificates have been issued;

(c) Historical information regarding the account of each shareholder, including dividends and distributions paid, if any, and the date and price for all transactions on a shareholder's account;

(d) Any stop or restraining order placed against a shareholder's account;

(e) Information with respect to withholdings of taxes on dividends paid to foreign accounts; and

(f) Any instruction as to letters of intent, record address, and any correspondence or instructions or privileges (such as a telephone exchange privilege), relating to the current maintenance of a shareholder's account.

In addition, CMS will keep and maintain on behalf of the respective Trust all records which the Trust or CMS is required to keep and maintain pursuant to any applicable statute, rule or regulation, including without limitation, Rule
31(a)-1 under the Investment Company Act of 1940, relating to the maintenance of records in connection with the services to be provided hereunder. CMS shall be obligated to maintain at its expense only those records necessary to

-5-

carry out its duties hereunder and the remaining records will be preserved at the Trust's expense for the periods prescribed by law.

17. Other Information Furnished. CMS will furnish to each Trust and the Distributor such other information, including shareholder lists and statistical information as may be agreed upon from time to time between CMS and the Trust. CMS shall notify each Trust of any request or demand to inspect the share records books of the Trust and will act upon the instructions of the Trust as to permitting or refusing such inspection.

18. Shareholder Inquiries. CMS will respond promptly to written correspondence from shareholders, registered representatives of broker-dealers engaged in selling Fund shares, the Trust and the Distributor relating to its duties hereunder, and such other correspondence as may from time to time be mutually agreed upon between CMS and each Trust. CMS also will respond to telephone inquiries from shareholders with respect to existing accounts.

19. Communications to Shareholders and Meetings. CMS will determine all shareholders entitled to receive, and will address and mail, all communications by a Trust to its shareholders, including quarterly and annual reports to shareholders, proxy material for meetings of shareholders and periodic communications to shareholders. CMS will receive, examine and tabulate return proxy cards for meetings of shareholders and certify the vote to the Trust.

20. Insurance. CMS will not reduce or allow to lapse any of its insurance coverage from time to time in effect, including but not limited to Errors and Omissions, Fidelity Bond and Electronic Data Processing coverage, without the prior written consent of each Trust.

21. Duty of Care and Indemnification. CMS will at all times use reasonable care and act in good faith in performing its duties hereunder. CMS will not be liable or responsible for delays or errors by reason of circumstances beyond its control, including without limitation, acts of civil or military authority, national or state emergencies, labor difficulties, fire, mechanical breakdown, flood or catastrophe, acts of God, insurrection, war, riots or failure of transportation, communication or power supply.

CMS may rely on certifications of the Secretary, any Assistant Secretary, the President, any Vice President, the Treasurer or any Assistant Treasurer of a Trust as to proceedings or facts in connection with any action taken by the shareholders or Trustees of that Trust, and upon instructions not inconsistent with this Agreement from the President, any Vice President, the Treasurer or any Assistant Treasurer of that Trust. CMS may apply to counsel for a Trust, at the Trust's expense, or its own counsel for advice whenever it deems expedient. With respect to any action taken on the basis of such certifications or instructions or in accordance with the advice of counsel for instructions or in accordance with the advice of counsel for a Trust, the Trust will indemnify and hold harmless CMS from any and all losses, claims, damages, liabilities and expenses (including reasonable counsel fees and expenses).

Each Trust will indemnify CMS against and hold CMS harmless from any and all losses, claims, damages, liabilities and expenses (including reasonable counsel fees and expenses) in respect to any claim, demand, action or suit not resulting from CMS's bad faith or negligence and arising out of, or in connection with, its duties on behalf of the Trust under this Agreement.

-6-

CMS shall also be indemnified and held harmless by each Trust against any loss, claim, damage, liability and expenses (including reasonable counsel fees and expenses) by reason of any act done by it in good faith and in reliance upon any instrument or certificate for shares believed by it (a) to be genuine and
(b) to be signed, countersigned or executed by any person or persons authorized to sign, countersign, or execute such instrument or certificate.

In any case in which a party to this Agreement may be asked to indemnify or hold harmless the other party hereto, the party seeking indemnification shall advise the other party of all pertinent facts concerning the situation giving rise to the claim or potential claim for indemnification, and each party shall use reasonable care to identify and notify the other promptly concerning any situation which presents or appears likely to present a claim for indemnification.

22. Employees. CMS is responsible for the employment, control and conduct of its agents and employees and for injury to such agents or employees or to others caused by such agents or employees. CMS assumes full responsibility for its agents and employees under applicable statutes and agrees to pay all employer taxes thereunder.

CMS shall maintain at its own expense insurance against public liability in a reasonable amount.

23. AML/CIP. CMS agrees to provide anti-money laundering services to each Trust and to operate the Trust's customer identification program, in each case in accordance with the written procedures developed by CMS and adopted or approved by the Trustees of the Trust and with applicable law and regulation.

24. Termination. This Agreement shall continue indefinitely until terminated (with respect to that Trust) by not less than ninety (90) days' written notice given by a Trust to CMS or, by six (6) months written notice given by CMS to the Trust. Upon termination hereof, the relevant Trust shall pay such compensation as may be due to CMS as of the date of such termination.

25. Successors. In the event that (i) in connection with termination of this Agreement a successor to any of CMS's duties or responsibilities hereunder is designated by a Trust by written notice to CMS, or (ii) CMA exercises its prerogative under paragraph 1 hereof to assume the duties and functions of CMS hereunder, CMS shall promptly, at the expense of the Trust (in the case of an event described in (i) above), transfer to such successor or CMA, as the case may be, a certified list of the shareholders of the Funds (with name, address and taxpayer identification or Social Security number), and historical record of the account of each shareholder and the status thereof, all other relevant books, records, correspondence and other data established or maintained by CMS under this Agreement in form reasonably acceptable to the Trust (if such form differs from the form in which CMS has maintained the same, the Trust shall pay any expenses associated with transferring the same to such form), and will cooperate in the transfer of such duties and responsibilities, including provision for assistance from CMS's personnel in the establishment of books, records and other data by such successor or CMA. CMS shall, in the case of an event described in (i) above, be entitled to reasonable compensation and reimbursement of its out-of-pocket expenses in respect of assistance provided in accordance

-7-

with the preceding sentence. Also, in the event of the termination of this Agreement, to the extent permitted by the agreements or licenses described below, CMS and CMA shall, if requested by the Trustees of the Trust, assign to any entity wholly owned, directly or indirectly, by Columbia Management Group, Inc. (or its successors) or by the Trust, or any of them, all of their rights under any existing agreements to which either of them is a party and pursuant to which either has a right to have access to data processing capability in connection with the services contemplated by this Agreement and under any licenses to use third-party software in connection with the services contemplated by this Agreement and under any licenses to use third-party software in connection therewith, and in connection with such assignment shall grant to the assignee an irrevocable right and license or sublicenses, on a non-exclusive basis, to use any software used in connection therewith and, on an exclusive basis, any proprietary rights or interest which it has under such agreements or licenses.

26. Use of Affiliated Companies and Subcontractors. In connection with the services to be provided by CMS or CMA under this Agreement, either CMS or CMA may, to the extent it deems appropriate, and subject to compliance with the requirements of applicable laws and regulations and upon receipt of approval of the Trustees, make use of (i) its affiliated companies and their directors, trustees, officers and employees and (ii) subcontractors selected by it, provided that it shall supervise and remain fully responsible for the services of all such third parties in accordance with and to the extent provided in this Agreement. All costs and expenses associated with services provided by any such third parties shall be borne by CMS, CMA or such parties, except to the extent specifically provided otherwise in this Agreement.

27. Confidentiality. Each of CMS and CMA agrees on behalf of itself and its employees to treat confidentially and as proprietary information of each Trust all records and other information relative to the Trust and its prior, present or potential shareholders and not to use such records and information for any purpose other than performance of its responsibilities and duties under this Agreement, except after prior notification to and approval in writing by the Trust, which approval shall not be unreasonably withheld and may not be withheld where CMS or CMA may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities or when so requested by the Trust.

28. Compliance. Each of CMS and CMA agree to comply with all applicable federal, state and local laws and regulations, codes, orders and government rules in the performance of its duties under this Agreement. Each of CMS and CMA agree to provide each Trust with such certifications, reports and other information as the Trust may reasonably request from time to time to assist it in complying with, and monitoring for compliance with, applicable laws, rules and regulations.

29. Miscellaneous. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts.

The captions in this Agreement are included for convenience of reference only and in no way define or limit any of the provisions of this Agreement or otherwise affect their construction or effect. This Agreement may be executed simultaneously in two or more counterparts, each of

A copy of the Agreement and Declaration of Trust of the Trusts that are organized as Massachusetts business trusts, as amended or restated from time to time, is on file with the Secretary of the Commonwealth of Massachusetts, and notice is hereby given that this Agreement is executed on behalf of each of these Trusts by an officer or Trustee of the Trust in his or her capacity as an officer or Trustee of the Trust and not individually and that the obligations of or arising out of this Agreement are not binding upon any of the Trustees, officers or shareholders individually but are binding only upon the assets and property of the Trust. Furthermore, notice is given that the assets and liabilities of each series of each Trust is separate and distinct and that the obligations of or arising out of this Agreement with respect to the series of each Trust are several and not joint, and to the extent not otherwise reasonably allocated among such series by the Trustees of the Trust, shall be deemed to have been allocated in accordance with the relative net assets of such series, and CMS and CMA agree not to proceed against any series for the obligations of another series.

The Funds agree that postage and mailing expenses will be paid on the day of or prior to mailing as agreed with CMS. In addition, the Funds will promptly reimburse CMS for any other unscheduled expenses incurred by CMS whenever the Funds and CMS mutually agree that such expenses are not otherwise properly borne by CMS as part of its duties under the Agreement.


Methodology of Allocating CMS Reimbursable Out-of-Pocket Expenses

CMS Reimbursable Out-of-Pocket Expenses are allocated to the Funds as follows:

A. Identifiable     Based on actual services performed and invoiced to a Fund.

B. Unidentifiable   Allocation will be based on three evenly weighted factors.

                    - number of shareholder accounts

                    - number of transactions

                    - average assets

c/o State Street Bank and Trust Company, as Operations and Administrative Agent
225 Franklin Street, MAO/7
Boston, MA 02110-2804

Re: Columbia Funds Credit Facility

Ladies and Gentlemen:

Reference is hereby made to the Credit Agreement for the Columbia Funds, dated as of July 23, 2004, as amended (as so amended, the "Credit Agreement"), by and among the registered investment companies listed on the signature pages thereof (collectively, the "Entities"), the lending institutions listed on the signature pages thereof (the "Banks"), State Street Bank and Trust Company, as operations agent (the "Operations Agent") for itself and such Banks as are or may become parties thereto, and State Street Bank and Trust Company, as administrative agent (the "Administrative Agent") for itself and such Banks as are or may become parties thereto. Capitalized terms which are used herein without definition and which are defined in the Credit Agreement shall have the same meanings herein as in the Credit Agreement.

Each Borrower hereby severally represents and warrants to the Banks and the Agents as follows:

(a) each Borrower listed on Schedule A (a "Removed Borrower") has merged or reorganized its assets with or into another entity, with such other entity being the survivor of such merger or consolidation and all Obligations of each Removed Borrower have been paid in full on or prior to the date of such merger or reorganization;

(b) each Borrower listed on Schedule B has changed its name as indicated on such Schedule;

(c) Columbia Funds Trust IX has changed its name to Columbia Funds Series Trust I; and

(d) each of the Borrowers listed on Schedule C has been reorganized into a newly established series (each, an "Additional Series") of Columbia Funds Series Trust I as indicated on such Schedule in a "shell" reorganization.


-2-

In connection with the foregoing, (i) Columbia Funds Series Trust I requests that each of the Additional Series becomes a Series under the Credit Agreement and for all purposes of the Loan Documents and (ii) each Borrower requests that Schedule 2 to the Credit Agreement be replaced by the Schedule 2 attached hereto. Each of the Banks and the Agents, by their signature below hereby agree to the foregoing requests provided that:

(1) the Operations Agent shall have received a Note for the account of PNC Bank National Association in an amount equal to such Bank's Commitment Amount, or, if less, the aggregate unpaid principal amount of such Bank's Loans, from each of the Borrowers (after giving effect to this letter agreement);

(2) the Operations shall have received a Form F.R. U-1 in favor of each Bank from each of the Borrowers (after giving effect to this letter agreement); and

(3) the Operations Agent shall have received an Allocation Notice with respect to each of the Borrowers (after giving effect to this letter agreement) that has been manually signed by an authorized officer of each of the Entities.

In consideration of the agreement of the Banks and the Agents to allow each Additional Series of Columbia Funds Series Trust I to become a Series hereunder, Columbia Funds Series Trust I, on behalf of each Additional Series, hereby covenants and agrees that it shall, on or prior to February 15, 2006, deliver to the Operations Agent the following documents:

(a) a manually signed certificate from the Secretary of Columbia Funds Series Trust I in form and substance satisfactory to the Operations Agent as to the incumbency of, and bearing manual specimen signatures of, the officers of Columbia Funds Series Trust I who are authorized to execute and take actions under the Loan Documents, as to the Custodian and Investment Adviser of each Additional Series, and certifying and attaching copies of (i) the declaration of trust of Columbia Funds Series Trust I (with the designation of each Additional Series) and by-laws as then in effect, (ii) duly authorized resolutions of the Board of Trustees of Columbia Funds Series Trust I authorizing for each Additional Series the transactions contemplated hereby, and (iii) the current Prospectus for each Additional Series (or the links to the SEC's website where each such Prospectus may be located);

(b) a certificate manually signed by an authorized officer of Columbia Funds Series Trust I, on behalf of each Additional Series, to the effect set forth in clauses (b) (if applicable), (c) and (d) of Section 3.02 of the Credit Agreement, such Certificate to be in form and substance satisfactory to the Operations Agent;

(c) an Asset Coverage Ratio Certificate manually signed by an authorized officer of Columbia Funds Series Trust I, on behalf of each Additional Series;

(d) a copy of the declaration of trust of Columbia Funds Series Trust I, with all amendments, certified as of a recent date by the Secretary of State of the Commonwealth of Massachusetts;


-3-

(e) certificates dated as of a recent date that are satisfactory to the Operations Agent and reflect that Columbia Funds Series Trust I is legally existing, in good standing and qualified to engage in business in Massachusetts and in each jurisdiction where its ownership, lease or operation of properties or the conduct of its business requires such qualification; and

(f) an opinion of Ropes & Gray LLP, counsel to Columbia Funds Series Trust I, which is satisfactory to the Operations Agent in all respects.

Columbia Funds Series Trust I, on behalf of each of the Additional Series, acknowledges and agrees that the failure to deliver such documents on or before February 15, 2006 shall constitute an Event of Default with respect to Columbia Funds Series Trust I on behalf of such Additional Series.

Each of the Borrowers (including Columbia Funds Series Trust I, on behalf of each of the Additional Series) ratifies and confirms in all respects all of its obligations to the Banks under the Credit Agreement, the Notes and the other Loan Documents, as amended hereby, and hereby affirms its absolute and unconditional promise to pay to the Banks the Loans made to it and all other amounts due from it under the Credit Agreement as amended hereby.

This letter agreement is a contract under seal under the laws of the Commonwealth of Massachusetts and shall for all purposes be construed in accordance with and governed by the laws of said Commonwealth (excluding the laws applicable to conflicts or choice of law). Except as specifically amended by this letter agreement, the Credit Agreement and all other agreements and instruments executed and delivered in connection with the Credit Agreement shall remain in full force and effect. This letter agreement is limited specifically to the matters set forth herein and does not constitute directly or by implication an amendment or waiver of any other provision of the Credit Agreement or any of the other Loan Documents. This letter agreement may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, and all of which together shall constitute one instrument. In proving this letter agreement it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom enforcement is sought. This letter agreement shall constitute a Loan Document.

A copy of each Entity's agreement and declaration of trust is on file with the Secretary of The Commonwealth of Massachusetts, and notice is hereby given that this instrument is executed by the Trustees and officers of such Entity as Trustees and officers, as the case may be, and not individually and that the obligations of this instrument are not binding upon any of the Trustees, officers or shareholders individually but are binding only upon the assets and property of the appropriate Entity.

FORM OF INDEMNIFICATION AGREEMENT

This Indemnification Agreement (the "Agreement") is made as of the date set forth on the signature page by and between each of the entities listed in Schedule A hereto (a "Fund"), and the trustee of the Fund whose name is set forth on the signature page (the "Trustee").

WHEREAS, the Trustee is a trustee of the Fund, and the Fund wishes the Trustee to continue to serve in that capacity; and

WHEREAS, the organizational documents of the Fund and applicable laws provide for the Fund to indemnify the Trustee in certain cases; and

WHEREAS, to induce the Trustee to continue to provide services to the Fund as a Trustee and to provide the Trustee with contractual assurance that indemnification will be available to the Trustee, the Fund desires to provide the Trustee with protection against personal liability and delineate certain procedural aspects relating to indemnification and advancement of expenses, as more fully set forth herein.

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual agreements set forth herein, the parties hereby agree as set forth below. Certain capitalized terms used herein are defined in Section 7.

1. INDEMNIFICATION. The Fund shall indemnify the Trustee against any and all Expenses actually and reasonably incurred by the Trustee in any Proceeding in which the Trustee may be or may have been involved as a party or otherwise or with which the Trustee may be or may have been threatened, while in office or thereafter, by reason of any alleged act or omission as a Trustee or by reason of his or her being or having been a trustee of the Fund, except with respect to any matter as to which the Trustee shall have been finally adjudicated in a relevant Proceeding not to have acted in good faith in the reasonable belief that his or her action was in the best interests of the Fund and except that the Trustee shall not be indemnified against any liability to the Fund or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

2. ADVANCEMENT OF EXPENSES. Expenses, including reasonable counsel fees incurred by the Trustee (but excluding amounts paid in satisfaction of judgments, in compromise or as fines or penalties), shall be paid from time to time by the Fund in advance of the final disposition of a Proceeding upon receipt by the Fund of an undertaking by or on behalf of the Trustee to repay amounts so paid to the Fund if it is ultimately determined that indemnification of such Expenses is not authorized under this Agreement, provided, however, that
(a) the Trustee shall provide security considered in the sole discretion of the Fund to be appropriate for such undertaking, (b) the Fund shall be insured against losses arising from any such advance payments, or (c) either a majority of the Independent Trustees acting on the matter (provided that a majority of such Independent Trustees then in office act on the matter), or Independent Counsel in a written opinion shall determine, based upon a review of readily available facts (as opposed


to a full trial-type inquiry), that there is reason to believe the Trustee will be found entitled to indemnification under this Agreement.

3. PRESUMPTIONS. For purposes of the determination or opinion referred to in clause (c) of Section 2 of this Agreement or clauses (x) or (y) of subsection
(h) of Section 5 of this Agreement, the Independent Trustees or Independent Counsel, as the case may be, shall be entitled to rely upon a rebuttable presumption that the Trustee has not engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the Trustee's office.

4. WITNESS EXPENSES. To the extent that the Trustee is, by reason of the Trustee's service to the Fund, a witness for any reason in any Proceeding to which such Trustee is not a party, such Trustee shall be indemnified against any and all Expenses actually and reasonably incurred by or on behalf of such Trustee in connection therewith.

5. PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION AND ADVANCEMENTS. A request by the Trustee for indemnification or advancement of Expenses shall be made in writing to the Secretary of the Fund, and shall be accompanied by such relevant documentation and information as is reasonably available to the Trustee. The Secretary of the Fund shall promptly advise the Board of such request.

(a) Methods of Determination. Upon the Trustee's request for indemnification or advancement of Expenses, a determination with respect to the Trustee's entitlement thereto shall be made in a manner consistent with the terms of this Agreement. The Trustee shall cooperate with the person or persons making such determination, including without limitation providing to such persons upon reasonable advance request any documentation or information that is not privileged or otherwise protected from disclosure and is reasonably available to the Trustee and reasonably necessary to such determination. Any failure by the Trustee to cooperate with the person or persons making such determination shall extend as necessary and appropriate the period or periods described in paragraph (c) of Section 5 regarding determinations deemed to have been made. Any Expenses reasonably incurred by the Trustee in so cooperating shall be borne by the Fund, irrespective of the determination as to the Trustee's entitlement to indemnification or advancement of Expenses. Any counsel selected pursuant hereto to make the relevant determination shall be an Independent Counsel.

(b) Independent Counsel. If the determination of entitlement to indemnification or advancement of Expenses is to be made by Independent Counsel, the Independent Counsel shall be selected by the Board, and the Fund shall give written notice to the Trustee advising the Trustee of the identity of the Independent Counsel selected. The Trustee may, within five days after receipt of such written notice, deliver to the Fund a written objection to such selection. Such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirement of independence set forth in Section 7, and shall set forth with particularity the factual basis of such assertion. Promptly after the receipt of such objection, another Independent Counsel shall be selected by the Board, and the Fund shall give written notice to the Trustee advising the Trustee of the identity of the Independent Counsel selected. The Trustee may, within five days after receipt of such written notice, deliver to the Fund a written objection to such selection. Such objection may be asserted only on the ground that the

2

Independent Counsel so selected does not meet the requirement of independence set forth in Section 7, and shall set forth with particularity the factual basis of such assertion. The Board shall determine the merits of the objection and, in its discretion, either determine that the proposed Independent Counsel shall, despite the objection, act as such hereunder or select another Independent Counsel who shall act as such hereunder.

If within 45 days (which period shall be extended by another 45 days if the Trustee objects to the first Independent Counsel selected by the Board as provided in the previous paragraph) after submission by the Trustee of a written request for indemnification or advancement of Expenses no such Independent Counsel shall have been finally selected as provided in the previous paragraph, then either the Fund or the Trustee may petition any court of competent jurisdiction for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person so appointed shall act as Independent Counsel.

The Fund shall pay all reasonable fees and Expenses charged or incurred by Independent Counsel in connection with his or her determinations pursuant to this Agreement, and shall pay all reasonable fees and Expenses of the Trustee incurred incident to the procedures described in this paragraph (b), regardless of the manner in which such Independent Counsel was selected or appointed.

(c) Failure to Make Timely Determination. Subject to paragraph (a) of
Section 5, if the person or persons empowered or selected to determine whether the Trustee is entitled to indemnification or advancement of Expenses (other than determinations that are made or to be made by a court) shall not have made such determination within 150 days after receipt by the Fund of the request therefor, the requisite determination of entitlement to indemnification or advancement of Expenses shall be deemed to have been made, and the Trustee shall be entitled to such indemnification or advancement, absent (i) an intentional misstatement by the Trustee of a material fact, or an intentional omission of a material fact necessary to make the Trustee's statement not materially misleading, in connection with the request for indemnification or advancement of Expenses, (ii) a prohibition of such indemnification or advancement under applicable law or the Fund's Agreement and Declaration of Trust or By-Laws, or
(iii) a requirement under the Investment Company Act of 1940, as amended, for insurance or security; provided, however, that the Fund, in its sole discretion, may extend such period for a reasonable period of time, not to exceed an additional 60 days, if the person or persons making the determination in good faith require such additional time to obtain or evaluate documentation or information relating thereto.

(d) Payment Upon Determination of Entitlement. If a determination is made pursuant to Section 1 or 2 (or is deemed to be made pursuant to paragraph (c) of this Section 5 and, in the case of advancement of Expenses, the other conditions are satisfied) that the Trustee is entitled to indemnification or advancement of Expenses, payment of any indemnification amounts or advancements owing to the Trustee shall be made within 30 days after such determination (and, in the case of advancements of Expenses, within 30 days after submission of supporting information, including the required undertaking and evidence of any required security). If such payment is not made when due, the Trustee shall be entitled to an adjudication in an appropriate court of The Commonwealth of Massachusetts, or in any other court of competent jurisdiction, of

3

the Trustee's entitlement to such indemnification or advancement. The Trustee shall commence any proceeding seeking such adjudication within one year following the date on which he or she first has the right to commence such proceeding pursuant to this paragraph (d). In any such proceeding, the Fund shall be bound by the determination that the Trustee is entitled to indemnification or advancement, absent (i) an intentional misstatement by the Trustee of a material fact, or an intentional omission of a material fact necessary to make his or her statement not materially misleading, in connection with the request for indemnification or advancements, (ii) a prohibition of such indemnification or advancement under applicable law, or (iii) a requirement under the Investment Company Act of 1940, as amended, for insurance or security.

(e) Appeal of Adverse Determination. If a determination is made that the Trustee is not entitled to indemnification or advancement, the Trustee shall be entitled to an adjudication of such matter in an appropriate court of The Commonwealth of Massachusetts or in any other court of competent jurisdiction. Alternatively, the Trustee, at his or her option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the rules of the American Arbitration Association. The Trustee shall commence such proceeding or arbitration within one year following the date on which the adverse determination is made. Any such judicial proceeding or arbitration shall be conducted in all respects as a de novo trial or arbitration on the merits, and the Trustee shall not be prejudiced by reason of such prior adverse determination.

(f) Expenses of Appeal. If the Trustee seeks arbitration or a judicial adjudication to determine or enforce his or her rights under, or to recover damages for breach of, the indemnification or Expense advancement provisions of this Agreement, the Trustee shall be entitled to recover from the Fund, and shall be indemnified by the Fund against, any and all Expenses actually and reasonably incurred by the Trustee in such arbitration or judicial adjudication, but only if the Trustee prevails therein. If it shall be determined in such arbitration or judicial adjudication that the Trustee is entitled to receive part but not all of the indemnification or advancement of Expenses sought, the expenses incurred by the Trustee in connection with such arbitration or judicial adjudication shall be appropriately prorated.

(g) Validity of Agreement. In any arbitration or judicial proceeding commenced pursuant to this Section 5, the Fund shall be precluded from asserting that the procedures and presumptions set forth in this Agreement are not valid, binding and enforceable against the Fund, and shall stipulate in any such court or before any such arbitrator that the Fund is bound by all the provisions of this Agreement.

(h) Lack of Adjudication. Notwithstanding any provision herein to the contrary, as to any matter disposed of (whether by a compromise payment, pursuant to a consent decree or otherwise) without an adjudication by a court, or by any other body before which the Proceeding was brought, that the Trustee either (a) did not act in good faith in the reasonable belief that the Trustee's action was in the best interests of the Fund or (b) is liable by reason of the Trustee's willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the Trustee's office, indemnification shall be provided if (x) approved as in the best interest of the Fund, after notice that it involves such indemnification, by at least a majority of the Independent Trustees acting on the matter (provided that a majority of such Independent Trustees then in office act on the matter), upon a determination, based upon a review of readily available facts (as opposed to a full trial-type inquiry) that the Trustee acted in good faith in the

4

reasonable belief that the Trustee's action was in the best interests of the Fund and that such indemnification would not protect the Trustee against any liability to which the Trustee would otherwise be subject by reason of the Trustee's willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the Trustee's office, or (y) there has been obtained an opinion in writing of Independent Counsel, based upon a review of readily available facts (as opposed to a full trial-type inquiry), to the effect that the Trustee appears to have acted in good faith in the reasonable belief that the Trustee's action was in the best interests of the Fund and that such indemnification would not protect the Trustee against any liability to which the Trustee would otherwise be subject by reason of the Trustee's willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the Trustee's office.

6. GENERAL PROVISIONS.

(a) Non-Exclusive Rights. The provisions for indemnification of, and advancement of Expenses to, the Trustee set forth in this Agreement shall not be deemed exclusive of any other rights to which the Trustee may otherwise be entitled, including any other rights to be indemnified, or have Expenses advanced, by the Fund. The Fund shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that the Trustee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise, if such payment is not recoverable from the Trustee.

(b) Continuation of Provisions. This Agreement shall be binding upon all successors of the Fund, including without limitation any transferee of all or substantially all assets of the Fund and any successor by merger, consolidation or operation of law, and shall inure to the benefit of the Trustee's spouse, heirs, assigns, devisees, executors, administrators and legal representatives. The provisions of this Agreement shall continue until the later of (1) ten years after the Trustee has ceased to provide any service to the Fund, and (2) the final termination of all Proceedings in respect of which the Trustee has asserted, is entitled to assert, or has been granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by the Trustee pursuant to Section 5 relating thereto. No amendment of the Agreement and Declaration of Trust or By-Laws of the Fund shall limit or eliminate the right of the Trustee to indemnification and advancement of Expenses set forth in this Agreement.

(c) Selection of Counsel. The Fund shall be entitled to assume the defense of any Proceeding for which the Trustee seeks indemnification or advancement of Expenses under this Agreement. Notwithstanding the foregoing, however, counsel selected by the Trustee shall conduct the defense of the Trustee to the extent reasonably determined by such counsel to be necessary to protect the interests of the Trustee, and the Fund shall indemnify the Trustee for the Expenses of such defense to the extent otherwise permitted under this Agreement, if (1) the Trustee reasonably determines that there may be a conflict in the Proceeding between the positions of the Trustee and the positions of the Fund or of other parties to the Proceeding that are indemnified by the Fund and not represented by separate counsel, or the Trustee otherwise reasonably concludes that representation of both the Trustee and the Fund or any such other parties by the same counsel would not be appropriate, or (2) the Proceeding involves the Trustee, but neither the Fund nor any such other party who is indemnified by the Fund, and the Trustee reasonably withholds consent to being represented by counsel selected by the Fund. If the Fund

5

shall not have elected to assume the defense of any such Proceeding for the Trustee within thirty days after receiving written notice thereof from the Trustee, the Fund shall be deemed to have waived any right it might otherwise have to assume such defense.

(d) Subrogation. In the event of any payment by the Fund pursuant to this Agreement, the Fund shall be subrogated to the extent of such payment to all of the rights of recovery of the Trustee, who shall, upon reasonable written request by the Fund and at the Fund's expense, execute all such documents and take all such reasonable actions as are necessary to enable the Fund to enforce such rights. Nothing in this Agreement shall be deemed (1) to diminish or otherwise restrict the right of the Fund or the Trustee to proceed or collect against any insurers or (2) to give such insurers any rights against the Fund under or with respect to this Agreement, including without limitation any right to be subrogated to the Trustee's rights hereunder, unless otherwise expressly agreed to by the Fund in writing, and the obligation of such insurers to the Fund and the Trustee shall not be deemed to be reduced or impaired in any respect by virtue of the provisions of this Agreement.

(e) Notice of Proceedings. The Trustee shall promptly notify the Fund in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding which may be subject to indemnification or advancement of Expenses pursuant to this Agreement, but no delay in providing such notice shall in any way limit or affect the Trustee's rights or the Fund's obligations under this Agreement, except to the extent the Fund can establish that it was materially harmed thereby.

(f) Notices. All notices, requests, demands and other communications to a party pursuant to this Agreement shall be in writing, addressed to such party at the address specified on the signature page of this Agreement (or such other address as may have been furnished by such party by notice in accordance with this paragraph), and shall be deemed to have been duly given when delivered personally (with a written receipt by the addressee) or two days after being sent (1) by certified or registered mail, postage prepaid, return receipt requested, or (2) by nationally recognized overnight courier service.

(g) Severability. If any provision of this Agreement shall be held to be invalid, illegal or unenforceable, in whole or in part, for any reason whatsoever, (1) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any
Section of this Agreement containing any provision that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby, and (2) to the fullest extent possible, the remaining provisions of this Agreement shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

(h) Modification and Waiver. This Agreement supersedes any existing or prior agreement between the Fund and the Trustee pertaining to the subject matter of indemnification, advancement of expenses and insurance, other than the Fund's Agreement and Declaration of Trust, By-Laws and the terms of any liability insurance policies, which shall not be modified or amended by this Agreement. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both parties or their respective successors or legal representatives; provided, however, that any supplements, modifications or amendments to the Agreement and Declaration of Trust, By-Laws or the terms of any liability insurance policies

6

shall be deemed not to constitute supplements, modifications or amendments to this Agreement. Any waiver by either party of any breach by the other party of any provision contained in this Agreement to be performed by the other party must be in writing and signed by the waiving party or such party's successor or legal representative, and no such waiver shall be deemed a waiver of similar or other provisions at the same or any prior or subsequent time.

(i) Headings. The headings of the Sections of this Agreement are for convenience only and shall not be deemed to control or affect the meaning or construction of any provision of this Agreement.

(j) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be an original, and all of which when taken together shall constitute one agreement.

(k) Applicable Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of The Commonwealth of Massachusetts without reference to principles of conflict of laws. The Fund and the Trustee submit to the jurisdiction of all state and federal courts sitting in The Commonwealth of Massachusetts.

(l) WAIVER OF RIGHT TO JURY TRIAL. BY EXECUTING THIS AGREEMENT, THE PARTIES KNOWINGLY AND WILLINGLY WAIVE ANY RIGHT THEY HAVE UNDER APPLICABLE LAW TO A TRIAL BY JURY IN ANY DISPUTE ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT OR THE ISSUES RAISED BY THAT DISPUTE.

7. DEFINITIONS. For purposes of this Agreement, the following terms shall have the following meanings:

(a) "Board" means the board of trustees of the Fund.

(b) "Expenses" shall include without limitation all judgments, penalties, fines, amounts paid or to be paid in settlement, ERISA excise taxes, liabilities, losses, interest, expenses of investigation, attorneys' fees, retainers, court costs, transcript costs, fees of experts and witnesses, expenses of preparing for and attending depositions and other proceedings, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other costs, disbursements or expenses of the type customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, or acting as a witness in a Proceeding.

(c) "Final adjudication" or "judgment" shall mean a final adjudication by court order or judgment of the court or other body before which a matter is pending, from which no further right of appeal or review exists.

(d) "Independent Counsel" shall mean a law firm, or a member of a law firm, that is experienced in matters of investment company law and neither at the time of designation is, nor in the five years immediately preceding such designation was, retained to represent (A) the Fund or the Trustee in any matter material to either, or (B) any other party to the Proceeding giving rise to a claim for indemnification or advancements hereunder. Notwithstanding the foregoing,

7

however, the term "Independent Counsel" shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Fund or the Trustee in an action to determine the Trustee's rights pursuant to this Agreement, regardless of when the Trustee's act or failure to act occurred.

(e) "Independent Trustee" shall mean a trustee of the Trust who is neither an "interested person" of the Fund as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended, nor a party to the Proceeding with respect to which indemnification or advances are sought nor a party to any other Proceeding based on the same or similar grounds which is then or has been pending.

(f) The term "Proceeding" shall include without limitation any threatened, pending or completed claim, demand, threat, discovery request, request for testimony or information, action, suit, arbitration, alternative dispute mechanism, investigation, hearing or other proceeding, including any appeal from any of the foregoing, whether civil, criminal, administrative or investigative.

(g) The Trustee's "service to the Fund" shall include without limitation the Trustee's status or service as a trustee or officer of the Fund and his or her service at the request of the Fund as a trustee, director or officer of another organization in which the Fund has any interest as a shareholder, creditor or otherwise.

8. MISCELLANEOUS. A copy of the Agreement and Declaration of Trust of the Fund, as amended or restated from time to time, is on file with the Secretary of the Commonwealth of Massachusetts, and notice is hereby given that this Agreement is executed on behalf of the Fund by an officer or Trustee of the Fund in his or her capacity as an officer or Trustee of the Fund and not individually and that the obligations of or arising out of this Agreement are not binding upon any of the Trustees, officers or shareholders individually but are binding only upon the assets and property of the Fund. Furthermore, notice is given that the assets and liabilities of each series of the Fund are separate and distinct and that the obligations of or arising out of this Agreement with respect to the series of the Fund are several and not joint, and to the extent not otherwise reasonably allocated among such series by the Trustees of the Fund, shall be deemed to have been allocated in accordance with the relative net assets of such series, and the Trustee agrees not to proceed against any series for the obligations of another series.

FORM OF

DISTRIBUTION PLAN

This Distribution Plan (the "Plan") relating to the shares (collectively, the "Shares") of the legal entities listed on Exhibits I through IV hereto (individually a "Trust" and collectively, the "Trusts"), on behalf of each series thereof listed on the applicable exhibit (each a "Fund"), has been adopted by the trustees or directors of the applicable Trust (the "Trustees") in conformity with Rule 12b-1 under the Investment Company Act of 1940 (the "1940 Act"). The terms and conditions of this Plan shall apply with respect to each Trust on behalf of each Fund.

Section 1. The Trust, on behalf of each Fund that is a series thereof, will pay to Columbia Funds Distributor, Inc., a Massachusetts corporation ("CFDI"), or to such other person as may from time to time be engaged and appointed to act as the distributor of its Shares (each such person, including CFDI, a "Distributor"), a fee (the "Distribution Fee") at the aggregate annual rate not to exceed the percentage of the Fund's average daily net assets attributable to such Shares set forth for such Fund on the applicable exhibit, as compensation for services rendered in connection with the sale of such Shares by the Distributor and related expenses incurred by the Distributor. Subject to such limit and subject to the provisions of Section 6 hereof, the Distribution Fee shall be as approved from time to time by (a) the Trustees and (b) the Disinterested Trustees (as defined below). The Distribution Fee shall be accrued daily and paid monthly or at such other intervals as the Trustees shall determine.

Each distribution agreement shall provide that the Distributor that is a party to such agreement will receive its Allocable Portion of the fee specified in such agreement. Unless and until a person other than CFDI shall serve as a distributor of the Shares of any the Trust, CFDI's "Allocable Portion" of the total Distribution Fee payable in respect of such Shares shall be 100%, and thereafter each Distributor's Allocable Portion of the total Distribution Fee payable in respect of Shares of any Fund shall be the portion of the Distribution Fee attributable to (i) outstanding Shares of the Fund sold by the Distributor ("Commission Shares"), plus (ii) Shares of the Fund issued in connection with the exchange of Commission Shares of another Fund and/or Shares of the Fund issued in reinvestment of dividends or capital gain distributions in respect of Commission Shares of another Fund, plus (iii) Shares of the Fund issued in reinvestment of dividends or capital gain distributions in respect of Commission Shares of the Fund; provided that the mechanics of attributing the portion of the Distribution Fee for a Fund to particular Shares for purposes of calculating a Distributor's Allocable Portion shall be as agreed by the Trust and the Distributor in light of systems capabilities for tracking the aging, exchange, and reinvestment experience of Shares sold by the Distributor.

A Distributor will be deemed to have fully earned its Allocable Portion of the Distribution Fee payable in respect of Shares of the Trust upon the sale of the Commission Shares of the Trust taken into account in determining such Distributor's Allocable Portion of such Distribution Fee.

-1-

The Distribution Fee shall be payable to the relevant Distributor or, with respect to such portion of the Distribution Fee as the Distributor may from time to time instruct, to the person or persons to whom such Distributor may from time to time instruct the Trust to make payments.

Section 2. Payments made to a Distributor pursuant to Section 1 may be used by the Distributor for any purpose, including (but not limited to) to compensate or reimburse the Distributor and any banks, broker/dealers or other financial institutions that have entered agreements with the Distributor in conformity with Section 8 ("Selling Agents") for distribution or sales support services rendered, and related expenses incurred, for or on behalf of the Fund. The Distributor may pay all or any portion of the Distribution Fee to any Selling Agents (including, but not limited to, any affiliate of the Distributor) as commissions, asset-based sales charges or other compensation with respect to the sale of the Shares, and may retain all or any portion of the Distribution Fee as compensation for the Distributor's services as agent for the distribution of Shares. All payments under this Distribution Plan are intended to qualify as "asset-based sales charges" as defined in Rule 2830 of the Conduct Rules of the National Association of Securities Dealers, Inc. (or any successor provision) as in effect from time to time. Notwithstanding anything herein to the contrary, no Fund or class of shares shall make any payments under the Plan that exceed the maximum amounts payable under applicable Conduct Rules of the National Association of Securities Dealers, Inc.

Joint distribution or sales support financing with respect to a Fund (which financing may also involve other investment portfolios or companies that are affiliated persons of the Fund, or affiliated persons of the Distributor) shall be permitted in accordance with applicable regulations of the Securities and Exchange Commission as in effect from time to time.

For each Fund class, the shareholders of which have approved (or may be deemed to have approved because the plan was adopted before any public offering of such Fund's Shares or the sale of such Shares to persons that are not affiliated persons of the Fund or affiliated persons of such persons) a distribution or servicing plan under Rule 12b-1 under the 1940 Act providing for the payments in excess of the annual rate at which Distribution Fees are paid hereunder, to the extent any payments made by such Fund pursuant to a Shareholder Servicing Plan and/or Servicing Agreement are deemed to be payments for activity primarily intended to result in the sale of Shares, such payments shall be deemed to have been approved pursuant to this Plan.

Section 3. Any officer designated by the Trust is authorized to execute and deliver, in the name of and on behalf of the Trust, a written agreement with a Distributor in such a form as may be approved by the Trustees from time to time. Such agreement shall authorize the Distributor to enter into written agreements with Selling Agents, based on such form(s) of sales support agreements as may be approved by the Board of Trustees from time to time and on such additional forms of agreement as the Distributor deems appropriate, provided that the Distributor determines that the Trust's responsibility or liability to any person under, or on account of any acts or statements of any such Selling Agent under, any such sales support agreement does not exceed its responsibility or liability under the form(s) approved by the Board of Trustees, and provided further that the Distributor determines that the overall terms of any such sales support

-2-

agreement are not materially less advantageous to the Trust than the overall terms of the form(s) approved by the Board of Trustees.

Section 4. Any person authorized to direct the disposition of monies paid or payable by the Trust pursuant to this Plan or any related agreement shall provide to the Trustees of the Trust, and the Trustees shall review, at least quarterly, a written report of the amounts so expended and the purposes for which such expenditures were made.

Section 5. This Plan shall continue in effect with respect to any class of Shares of a Fund for a period of more than one year only so long as such continuance is specifically approved at least annually by votes of the majority of the Trustees and a majority of the Disinterested Trustees, cast in person at a meeting called for the purpose of voting on this Plan.

Section 6. This Plan may not be amended to increase materially the amount to be spent with respect to any class of Shares of a Fund for distribution hereunder without approval by a vote of at least a majority of the outstanding Shares of such class, and all material amendments of this Plan shall be approved in the manner provided for continuation of this Plan in Section 5.

Section 7. This Plan is terminable at any time with respect to any class of Shares of any Fund by vote of a majority of the Disinterested Trustees, or by vote of a majority of the outstanding Shares of such class.

Section 8. All agreements with any person relating to implementation of this Plan shall be in writing, and any agreement related to this Plan shall provide:

A. That such agreement may be terminated with respect to any class of Shares of a Fund at any time, without payment of any penalty, by vote of a majority of the Disinterested Trustees or by vote of a majority of the outstanding Shares of such class, on not more than 60 days' written notice to any other party to the agreement; and

B. That such agreement shall terminate automatically in the event of its assignment.

Section 9. The Trust will preserve copies of this Plan, and any agreement or written report regarding this Plan presented to the Board of Trustees for a period of not less than six years.

Section 10. As used in this Plan, (a) the term "Disinterested Trustees" shall mean those Trustees who are not interested persons of the Trust, and have no direct or indirect financial interest in the operation of this Plan or any agreements related to it, and (b) the terms "assignment" and "interested person" shall have the respective meanings specified in the Act and the rules and regulations thereunder, and the term "majority of the outstanding Shares of the Fund" shall mean the lesser of the 67% or the 50% voting requirements specified in clauses (A) and (B), respectively, of the third sentence of Section 2(a)(42) of the Act, all subject to such exemptions as may be granted by the Securities and Exchange Commission.

-3-

Section 11. This Plan is adopted by the Trustees as Trustees of the Trust, and not individually, and the obligations of the Trust hereunder are not those of the Trustees, officers, representatives or agents of the Trust individually, but in such capacities, and are not binding upon any of the Trustees, shareholders, officers, representatives or agents of the Trust personally, but bind only the assets of the Trust, and all persons dealing with a Trust or Fund must look solely to the Trust property belonging to such Fund for the enforcement of any claims against the Trust.

Approved: May 11, 2005 (revised to reflect Fund reorganizations as of March 27, 2006)

CODE OF ETHICS

BOARD APPROVAL RECEIVED   December 2005
VERSION EFFECTIVE DATE    January 3, 2006
DATE LAST REVIEWED        January 3, 2006
APPLICABLE AUTHORITY      Section 17(j) of the 1940 Act;
                          Rule 17j-1 under the 1940 Act

OVERVIEW AND STATEMENT

Section 17(j) of the 1940 Act makes it unlawful for any affiliated person of or principal underwriter for a registered investment company, or any affiliated person of an investment adviser of or principal underwriter for an investment company, to engage in any act, practice or course of business in connection with the purchase or sale, directly or indirectly, by such person of any security held or to be acquired by such investment company in contravention of such rules as the SEC may adopt to prevent any such acts, practices and courses of business as are fraudulent, deceptive or manipulative. Section 17(j) is intended to permit the SEC to create guidelines to prohibit persons affiliated with investment companies and their investment advisers and principal underwriters from engaging in securities transactions for their personal accounts when such transactions are likely to conflict with the investment programs of such investment companies. In response to Section 17(j), the SEC adopted Rule 17j-1 under the 1940 Act. Rule 17j-1 (1) prescribes an anti-fraud standard for affiliated persons of investment companies, their investment advisers and principal underwriters, (2) requires investment companies, their investment advisers and principal underwriters to adopt codes of ethics applicable to certain affiliated persons known as "access persons," subject to certain exceptions and (3) requires "access persons" to report to the investment company all transactions in securities of which they are the beneficial owners, subject to certain exceptions.

The Code of Ethics (the "Code") set forth below shall apply to each Fund advised by BAC whose Board specifically adopts the Code with respect to such Fund. A person who is an "access person" of the Fund and an "access person" of the Adviser (including any Subadviser) or principal underwriter of the Fund is only required to report under and otherwise comply with the Adviser's, Subadviser's or principal underwriter's Rule 17j-1 code of ethics, provided that such code has been adopted pursuant to and in compliance with Rule 17j-1 and that the Board of the Fund has also approved such code pursuant to Rule 17j-1. Such persons, however, are still subject to the principles and prohibitions contained in Section A of the Fund's Code.

FUND LEVEL POLICIES AND PROCEDURES

A. Legal Requirements.


Rule 17j-1(b) under the 1940 Act makes it unlawful for any officer or Board member of a Fund (as well as other persons who are "Access Persons"(1)), in connection with the purchase or sale, directly or indirectly, by such person of a security "held or to be acquired"(2) by the Fund:

1. To employ any device, scheme or artifice to defraud the Fund;

2. To make any untrue statement of a material fact to the Fund or omit to state a material fact necessary in order to make the statements made to the Fund, in light of the circumstances under which they are made, not misleading;

3. To engage in any act, practice or course of business that operates or would operate as a fraud or deceit on the Fund; or

4. To engage in any manipulative practice with respect to the Fund.

The policies, restrictions and procedures included in this Code are designed to prevent violations of these prohibitions. (See Rule 17j-1(b).)

In addition, the Investment Company Institute (the "ICI") has suggested that investment companies adopt additional measures to obviate conflicts, prevent and detect abusive practices and preserve the confidence of investors. The policies, restrictions and procedures included in this Code are intended to substantially conform to the additional measures suggested by the ICI.

B. Fund Policies.

It is the policy of the Fund that no Access Person of the Fund shall engage in any act, practice or course of conduct that would violate the provisions of Rule 17j-1(b) set forth above. In this regard, each Access Person has a duty at all times to place the interests of Fund shareholders first and is required to conduct all personal securities transactions consistent with the letter and spirit of this Code and in such a manner as to avoid any actual or potential conflicts of interest or any abuse of the Access Person's position of trust and responsibility. It is a fundamental standard that Access Persons should not take inappropriate advantage of their positions. (See Report of Advisory Group on Personal Investing, May 9, 1994).

C. Restrictions.

1. No Access Person shall purchase or sell, directly or indirectly, any "Covered Security"(3) where he or she has, or by reason of such transaction acquires or disposes of, any direct or indirect "Beneficial Ownership"(4) and where he or she knows or should have known, at the time of such purchase or sale, that the Covered Security:

(a) is being considered for purchase or sale by the Fund; or


(b) is being purchased or sold by the Fund.

2. All Investment Personnel must obtain approval from the Senior Compliance Manager before directly or indirectly acquiring Beneficial Ownership in any securities in an "Initial Public Offering"(5) or in a "Limited Offering."(6)

3. This Code sets forth additional requirements and restrictions that "Investment Personnel"(7) must comply with under this Code. To review such requirements and restrictions, please refer to Section H of this Code.

4. The restrictions set forth in Section C.1. shall not apply to:

(a) purchases or sales of any Covered Securities that are not eligible for purchase or sale by the Fund;

(b) purchases or sales over which the Access Person has no direct or indirect influence or control (i.e., non-volitional trades);

(c) purchases which are part of an "Automatic Investment Plan"(8);

(d) purchases which are effected upon the exercise of rights issued by an issuer pro rata to all holders of a class of its securities, to the extent such rights were acquired from the issuer, and sales of such rights;

(e) sales which are effected pursuant to a tender offer or similar transaction involving an offer to acquire all or a significant portion of a class of securities; or

(f) purchases or sales in an investment advisory account of the Access Person (either or alone or with others) over which the investment adviser for the account exercises investment discretion if the Access Person did not have knowledge of the transaction before it was executed.

1. In addition, the restrictions set forth in Section C.1. shall not apply to purchases or sales which are only remotely potentially harmful to the Fund, as determined by the Senior Compliance Manager, because they would be very unlikely to affect a highly institutional market. Any request to purchase or sell securities which are only remotely potentially harmful to the Fund must be made in writing. Similarly, the related approval or denial of such a request will be provided in writing.

D. Procedures.

1. In order to provide the Fund with information to enable it to determine with reasonable assurance whether the provisions of Rule 17j-1(b) are being


observed by its Access Persons, each Access Person shall file the following reports with the Fund, unless the Access Person is exempt as described above in the introduction or under Section D.1.(d) from reporting:

(A) INITIAL HOLDINGS REPORT

Except in the case of Independent Board Members as provided in Section D(1) below, each Access Person of the Fund shall submit a report in the form attached hereto as Appendix A to the Senior Compliance Manager showing all holdings in Covered Securities in which the Access Person had any direct or indirect Beneficial Ownership and all accounts maintained at brokers, dealers, and/or banks where securities are held (or accounts where securities could have been held) for the direct or indirect benefit of the Access Person as of the date the person became an Access Person. Such report shall be filed not later than 10 days after the person becomes an Access Person. Information in the initial report must be current as of a date no more than 45 days prior to the date the person became an Access Person. In lieu of providing such a report, an Access Person may provide account statements to the Senior Compliance Manager. (See Rule 17j-1(d)(1)(i)).

(B) QUARTERLY TRANSACTION REPORT

Except in the case of Independent Board Members as provided in Section D(1) below, each Access Person of the Fund shall submit a report in the form attached hereto as Appendix B to the Senior Compliance Manager showing all transactions effected during the quarter in Covered Securities in which the person had any direct or indirect Beneficial Ownership and all accounts established at brokers, dealers, and/or banks that held any securities during the quarter for the direct or indirect benefit of the Access Person. Such report shall be filed not later than 30 days after the end of each calendar quarter. In lieu of providing such a report, an Access Person may arrange for broker trade confirmations and account statements to be provided directly to the Senior Compliance Manager. (See Rule 17j-1(d)(1)(ii)).

(C) ANNUAL HOLDINGS REPORT

Except in the case of Independent Board Members as provided in Section D(1) below, each Access Person of the Fund shall submit a report in the form attached hereto as Appendix C to the Senior Compliance Manager showing all holdings of Covered Securities in which the Access Person had direct or indirect Beneficial Ownership and all accounts maintained at brokers, dealers, and/or banks where securities are held (or accounts where securities could have been held) for the direct or indirect benefit of the Access Person as of the calendar year end. Information in the annual report must be current as of a date no more than 45 days before the report is submitted to the Fund. Such report shall be filed not later than 30 days after the end of each calendar year.


In lieu of providing such a report, an Access Person may provide account statements to the Senior Compliance Manager. (See Rule 17j-1(d)(1)(iii)).

(D) EXCEPTIONS FROM REPORTING REQUIREMENTS

(i) A person need not make a report that would otherwise be required by Section D with respect to transactions effected for, and Covered Securities held in, any account over which the person has no direct or indirect influence or control.

(ii) Each Fund Board member who is an Independent Board Member and who would be required to make a report solely by reason of being a Fund Board member, need not make an initial holdings report or annual holdings report as would otherwise be required by Section D.1.(a) or D.1.(c) above. An Independent Board Member is also exempt from the requirement to submit a quarterly transaction report as required by
Section D.1.(b), but only if during the applicable calendar quarter there has not occurred any transaction by the Independent Board Member in a Covered Security where the Independent Board Member knew or, in the ordinary course of fulfilling the Independent Board Member's official duties as an Independent Board Member, should have known that during the 15-day period immediately before or after the date of the Independent Board Member's transaction in the Covered Security, the Fund purchased or sold the Covered Security, or the Fund or its Adviser considered purchasing or selling the Covered Security.

(iii) An Access Person need not make a quarterly transaction report under Section D.1.(b) with respect to transactions effected pursuant to an Automatic Investment Plan (unless such transaction would override or otherwise depart from any pre-set schedule or allocation). (See Rule 17j-1(d)(2)).

2. Every Access Person of the Fund shall provide an annual certification in the form of Appendix D to the Senior Compliance Manager. This requirement applies to all Fund Board members, including those who are Independent Board Members.

3. The Board shall appoint the Senior Compliance Manager to be responsible for administering this Code. In addition, an appropriate management or compliance person shall be responsible for reviewing the reports of the Senior Compliance Manager submitted pursuant to this Code. (See Rule 17j-1(d)(3)).


4. The Senior Compliance Manager shall notify each Access Person of the Fund who may be required to make reports pursuant to this Code that such person is subject to reporting requirements and shall deliver a copy of this Code to each such person. Any amendments to this Code shall be similarly furnished to each person to whom this Code is applicable. (Rule 17j-1(d)(4)).

5. The Senior Compliance Manager shall report to the Board at the next regularly scheduled Board meeting:

(a) apparent violations of the requirements stated herein; and

COORDINATION WITH OVERVIEW AND IMPLEMENTATION STATEMENT

This policy and procedures statement should be read and interpreted in conjunction with the Overview and Implementation of Compliance Policies and Procedures statement at the beginning of this compliance manual.


(1) "Access Person" means: (i) any "Advisory Person" of the Fund or its Adviser (which term includes, for purposes of this Code, any Subadviser); (ii) all of the Adviser's directors and officers; (iii) all of the Fund's Board members and officers; and (iv) any director or officer of any principal underwriter of the Fund who, in the ordinary course of business, makes, participates in or obtains information regarding the purchase or sale of "Covered Securities" (defined below) by the Fund, or whose functions or duties in the ordinary course of business relate to the making of any recommendations with respect to such purchases or sales. Categories (ii) and (iii) are based upon a presumption that such persons are Advisory Persons of the Fund or its Adviser, which may be rebutted in light of pertinent facts and circumstances. An "Advisory Person" of the Fund or its Adviser means any Board member, director, officer or employee of the Fund or its Adviser (or of any entity in a control (as defined in Section 2(a)(9) of the 1940 Act) relationship to the Fund or its Adviser) who, in connection with his or her regular functions or duties, makes, participates in or obtains information regarding the purchase or sale of "Covered Securities" (defined below) by the Fund, or whose functions relate to the making of any recommendations to the Fund with respect to such purchases or sales. "Advisory Person" also includes any natural person in a control relationship to the Fund or its Adviser who obtains information concerning recommendations made to the Fund with regard to the purchase or sale of "Covered Securities" by the Fund.

(2) A security "held or to be acquired" by the Fund means any "Covered Security" (defined below) which, within the most recent 15 days: (i) is or has been held by the Fund; or (ii) is being or has been considered by the Fund or its Adviser for purchase by the Fund; and any option to purchase or sell, and any security convertible into or exchangeable for, a "Covered Security."

(3) A "Covered Security" (or "Covered Securities") means a security as defined in section 2(a)(36) of


the 1940 Act, other than (i) direct obligations of the Government of the United States; (ii) bankers' acceptances, bank certificates of deposit, commercial paper and high quality short-term debt instruments, including repurchase agreements; and (iii) shares issued by open-end investment companies.

(4) A person will be treated as the "Beneficial Owner" of a security under this policy only if he or she has a direct or indirect pecuniary interest in the security, as interpreted by reference to Rule 16a-1(a)(2) under the 1934 Act.

(1) A direct pecuniary interest is the opportunity, directly or indirectly, to profit, or to share the profit, from the transaction.

(2) An indirect pecuniary interest is any nondirect financial interest, but is specifically defined in Rule 16a-1 of the 1934 Act to include securities held by members of the person's immediate family sharing the same household; securities held by a partnership of which the person is a general partner; securities held by a trust of which the person is a trustee and has both investment control and a pecuniary interest, the settlor if the person can revoke the trust, or a beneficiary if the person has or shares investment control with the trustee; and equity securities which may be acquired upon exercise of an option or other right, or through conversion.

For interpretive guidance on whether a person has a direct or indirect pecuniary interest in a transaction, the person should consult the Senior Compliance Manager. A report shall not be construed as an admission by the person making the report that he or she has any direct or indirect beneficial ownership in the security.

(5) In this Code, "Initial Public Offering" shall mean an offering of securities registered under the 1933 Act, the issuer of which, immediately before the registration, was not subject to the reporting requirements of Sections 13 or 15(d) of the 1934 Act.

(6) In this Code, "Limited Offering" shall mean an offering that is exempt from registration under the 1933 Act pursuant to Section 4(2) or Section 4(6) of, or Rule 504, Rule 505 or Rule 506 under, the 1933 Act.

(7) "Investment Personnel" includes any employee of the Fund or its Adviser (or of any company in a control relationship to the Fund or its Adviser) who, in connection with his or her regular functions or duties, makes or participates in making recommendations regarding the purchase or sale of securities by the Fund. Investment Personnel also includes any natural person who controls the Fund or its Adviser and who obtains information concerning recommendations made to the Fund regarding the purchase or sale of securities by the Fund.

(8) An "Automatic Investment Plan" means a program in which regular periodic purchases (or withdrawals) are made automatically in (or from) investment accounts in accordance with a predetermined schedule and allocation. An Automatic Investment Plan includes a dividend reinvestment plan.

(9) For purposes of this Code, "Short-term Trading" is defined as a purchase and sale, or sale and purchase, of the same (or equivalent) securities which both occur within any 60-day period.

This policy is the property of the Funds and must not be provided to any external party without express prior consent from the CCO or the appropriate BAC legal or compliance unit.

APPENDIX E

POLICY STATEMENT ON INSIDER TRADING

A. Introduction.

The Fund seeks to foster a reputation for integrity and professionalism. That reputation is a vital business asset. The confidence and trust placed in us by investors in the Fund is something we should value and endeavor to protect. To further that goal, this Policy Statement implements procedures to deter the misuse of material, nonpublic information in securities transactions.

Trading securities while in possession of material, nonpublic information or improperly communicating that information to others may expose you to stringent penalties. Criminal sanctions may include a fine of up to $1,000,000 and/or ten years imprisonment. The SEC can recover the profits gained or losses avoided through the violative trading, impose a penalty of up to three times the illicit windfall and issue an order permanently barring you from the securities industry. Finally, you may be sued by investors seeking to recover damages for insider trading violations.

Regardless of whether a government inquiry occurs, the Fund views seriously any violation of this Policy Statement. Such violations constitute grounds for disciplinary sanctions, including dismissal.

B. Scope of the Policy Statement.

This Policy Statement is drafted broadly; it will be applied and interpreted in a similar manner. This Policy Statement applies to securities trading and information handling by Access Persons, as defined in the Fund's Code of Ethics.

The law of insider trading is unsettled; an individual legitimately may be uncertain about the application of the Policy Statement in a particular circumstance. Often, a single question can forestall disciplinary action or complex legal problems. You should direct any questions relating to the Policy Statement to the Senior Compliance Manager. You also must notify the Senior Compliance Manager immediately if you have any reason to believe that a violation of the Policy Statement has occurred or is about to occur.

C. Policy Statement.

No person to whom this Policy Statement applies may trade, either personally or on behalf of others, while in possession of material, nonpublic information; nor may the Fund's Access Persons communicate material, nonpublic information to others in violation of the law. This section reviews principles important to the Policy Statement.


1. What is Material Information?

Information is "Material" when there is a substantial likelihood that a reasonable investor would consider it important in making his or her investment decisions. Generally, this is information disclosure of which will have a substantial effect on the price of a company's securities. No simple "bright line" test exists to determine when information is material; assessments of materiality involve a highly fact-specific inquiry. For this reason, you should direct any questions about whether information is material to the Senior Compliance Manager.

Material information often relates to a company's results and operations including, for example, dividend changes, earnings results, changes in previously released earnings estimates, significant merger or acquisition proposals or agreements, major litigation, liquidation problems, and extraordinary management developments.

Material information also may relate to the market for a company's securities. Information about a significant order to purchase or sell securities may, in some contexts, be deemed material. Similarly, prepublication information regarding reports in the financial press also may be deemed material. For example, the Supreme Court upheld the criminal convictions of insider trading defendants who capitalized on prepublication information about the Wall Street Journal's "Heard on the Street" column.

2. What is Nonpublic Information?

Information is "Public" when it has been disseminated broadly to investors in the marketplace. Tangible evidence of such dissemination is the best indication that the information is public. For example, information is public after it has become available to the general public through a public filing with the SEC or other government agency, the Dow Jones "tape" or the Wall Street Journal or some other publication of general circulation, and after sufficient time has passed so that the information has been disseminated widely.

3. Identifying Inside Information

Before executing any trade for yourself or others, including the Fund, you must determine whether you have access to material, nonpublic information. If you think that you might have access to material, nonpublic information, you should take the following steps:

(i) Report the information and proposed trade immediately to the Senior Compliance Manager.

(ii) Do not purchase or sell the securities on behalf of yourself or others, including the Fund.

(iii) Do not communicate the information inside or outside the Fund, other than to the Senior Compliance Manager.

(iv) After the Senior Compliance Manager has reviewed the issue, the Fund will determine whether the information is material and nonpublic and, if so, what action the Fund should take.

You should consult with the Senior Compliance Manager before taking any action. This degree of caution will protect you and the Fund.


4. Contact with Public Companies

The Fund's contacts with public companies represent an important part of our research efforts. The Fund may make investment decisions on the basis of the Fund's conclusions formed through such contacts and analysis of publicly-available information. Difficult legal issues arise, however, when, in the course of these contacts, a Fund employee or other person subject to this Policy Statement becomes aware of material, nonpublic information. This could happen, for example, if a company's Chief Financial Officer prematurely disclosed quarterly results to an analyst or an investor relations representative makes a selective disclosure of adverse news to a handful of investors. In such situations, the Fund must make a judgment as to its further conduct. To protect yourself and the Fund, you should contact the Senior Compliance Manager immediately if you believe that you may have received material, nonpublic information.

5. Tender Offers

Tender offers represent a particular concern in the law of insider trading for two reasons. First, tender offer activity often produces extraordinary gyrations in the price of the target company's securities. Trading during this time period is more likely to attract regulatory attention (and produces a disproportionate percentage of insider trading cases). Second, the SEC has adopted a rule that expressly forbids trading and "tipping" while in possession of material, nonpublic information regarding a tender offer received from the tender offeror, the target company or anyone acting on behalf of either. Fund employees and others subject to this Policy Statement should exercise particular caution any time they become aware of nonpublic information relating to a tender offer.
